GiveButter vs. Zeffy vs. RallyUp: The Honest 2026 Comparison

If you’re researching fundraising platforms in 2026, these three come up together constantly. They overlap enough to feel interchangeable and differ enough that the wrong pick can cost you real money or real capability. So let’s set them side by side plainly — fee for fee, feature for feature, raffle for raffle, gala for gala — and name each platform’s genuine strengths, not just its gaps. A comparison you can’t trust isn’t worth reading.

Which platform is right for you? The 60-second verdict

Each platform is best at a different job: Zeffy wins on cost, GiveButter wins on the back office, and RallyUp wins on fundraising range and live events. A fair comparison starts by saying what each is best at — including where it beats the other two outright.

Zeffy is the true zero-fee specialist.

Its pitch is simple and real: the nonprofit pays nothing — no platform fee and no payment-processing fee — because costs are funded by optional tips donors add at checkout. On fee purity, no major platform matches it. Zeffy serves 100,000+ nonprofits, has raised $2B+, and is genuinely simple for volunteer-run organizations. It also offers memberships (with renewals and member cards), which neither of the others does.

GiveButter leads on the back office, not the fundraising range.

Its real strength is the broad, mostly-free suite around the donation: a capable CRM (unlimited contacts), built-in email, outbound texting on its paid tier, a large integration library, and a financial layer (a wallet paying 2.5% APY, cards, QuickBooks sync). The fundraising itself is narrower — three campaign types (forms, pages, events) versus RallyUp’s 12+ — so GiveButter fits best when your donor database and communications matter more to you than how many ways you can raise.

RallyUp is the full fundraising suite that’s still easy to launch.

Start with one campaign — a raffle, an online auction, a donation page — and RallyUp is just as easy to use as the other two, and often faster to get live: launch from an Instant Fundraiser Template in 15–20 minutes, or let RallyUp’s team build your first campaign for free with Create My Campaign. Then, when you’re ready, it’s the only one of the three that lets you add and combine 12+ campaign types in a single Campaign with one checkout via Full Stack Fundraising — so the platform grows with you instead of boxing you in. It’s also the clear pick for galas and live auctions, for Sweepstakes and A-Thons (which the others don’t offer at all), and for Raffles that draw the winner inside the platform.

None of that requires exaggeration. The rest of this guide shows the evidence.

The master scorecard: how do they compare at a glance?

Each platform has its own strengths and clear wins. Here’s how they line up at a glance.

Two rows go decisively to the others — cost to Zeffy, built-in CRM and integrations to GiveButter — and both deserve real weight. Most of the rows that turn effort into dollars at an event, though, tilt toward RallyUp. Which set matters more depends entirely on what you’re running.

How much does each platform cost? Three kinds of “free”

Each platform can cost your organization $0 in platform fees, but “free” means something different in each case. This is the most-searched question about all three, so let’s be precise — the honest question is who pays, and for what capability.

Zeffy — truly zero, funded by donor tips.

Zeffy covers both the platform fee and the payment-processing fee, so a $100 gift can deposit as a full $100 whether or not the donor tips. That’s a real advantage, best-in-class on fee purity.

The model is funded by an optional tip Zeffy adds to the donor’s total at checkout, and it’s pre-selected by default: third-party coverage reports the default at 17% on gifts up to $99.49 and 15% at $99.50 and above (Donorbox), with about 60% of donors tipping (Zeffy). Donors can lower or remove it, though it requires an active opt-out.

One independent analysis estimates donors effectively pay around 12.75% through tips (4aGoodCause). The takeaway isn’t that the model is bad — plenty of platforms, RallyUp included, use optional donor tips on their free tiers — it’s simply that with Zeffy the cost sits with your donors at a high default rather than with your nonprofit. One detail worth knowing on the donor-experience side: per Zeffy’s own help center, if a donor is refunded, the tip to Zeffy isn’t returned automatically — a standard refund covers the donation only, and getting the tip back takes a separate request to Zeffy.

Two other notes: Zeffy is the merchant of record (your organization doesn’t own its donor payment tokens, which adds friction if you ever migrate recurring donors — 4aGoodCause), and it doesn’t support PayPal or Venmo.

GiveButter — free with tips on, or a flat 3% with tips off.

By GiveButter’s own pricing documentation, if you keep optional donor tips enabled, the Givebutter Guarantee (effective September 9, 2025) covers processing fees and your nonprofit keeps 100%. If you turn tips off — which some organizations prefer, especially those funded by grants or corporate gifts where a tip prompt feels awkward — a flat 3% platform fee applies across all campaign types, plus processing (2.9% + $0.30 cards, 1.9% + $0.30 ACH).

Separately, Givebutter Plus is a paid, contact-based subscription (from $29/month for under 250 contacts, scaling with your contact count) that unlocks automations, an advanced email editor, outbound SMS, custom reports, direct mail, and phone support. The free CRM itself has unlimited contacts.

RallyUp — a free plan, or per-Component Flex pricing with no subscription.

RallyUp’s Free plan runs on optional donor tipping with no platform fee, and its Donation Pages are free with no platform fee and no required donor tip at all — turn tipping off and you still pay zero.

Its Flex plan charges per Component rather than a subscription: 0% on Donation Pages, 2.9% on Ticketing & Registration and Storefront, 4.9% on Auctions, Crowdfunding, Fund-a-Need, Paddle Raise+, and A-Thons, and 6.9% on Raffles and Sweepstakes — plus processing (1.9–2.9% + $0.30 to Stripe or PayPal, which RallyUp takes no cut of and which can be passed to donors on Flex).

RallyUp also caps auction platform fees at $100 per item regardless of the winning bid.

There are no contracts, subscriptions, or setup fees. You can see the full breakdown on RallyUp’s pricing by campaign type.

Pricing dimension	GiveButter	Zeffy	RallyUp
Platform fee (tips on / default)	$0 (Givebutter Guarantee)	$0	$0
Platform fee (tips off)	Flat 3%, all campaign types	n/a (tip-funded)	Free plan $0; Flex 2.9–6.9% by Component
Payment processing	2.9% + $0.30 (1.9% ACH)	Covered by tips ($0 to org)	1.9–2.9% + $0.30 (Stripe/PayPal)
Default donor tip	15% suggested	Pre-selected 17% (≤$99.49) / 15% (≥$99.50)	Optional, not pre-required
Donation pages with no required donor tip	—	—	Yes
Paid subscription tier	Plus (from $29/mo, contact-based)	None	None (Enterprise is custom)
PayPal / Venmo	Cards, Apple/Google Pay, ACH	No PayPal or Venmo	PayPal supported
You own your donor data	Yes	Merchant of record	Yes

The honest takeaway on cost.

For a simple donation form where zero cost is everything, Zeffy wins outright — say it plainly. GiveButter is effectively free when donors tip and predictable at a flat 3% when they don’t.

RallyUp’s Free plan and no-tip Donation Pages keep entry costs at zero too.

But the fee is only half the equation, and arguably the smaller half. The number that actually lands in your account is what you raise minus what you pay — and a platform that helps you raise more can send you home with more even if a particular fee line is a point or two higher. RallyUp reports that campaigns combining multiple Components raise about 38% more on average; a bigger total generally beats a smaller total at a lower rate.

Put simply, the lowest fee isn’t a bargain if you take less money home. So weigh cost alongside the real question — how much will your next fundraiser actually raise? — rather than in isolation.

Campaign types: a toolbox, or one combined campaign?

The structural difference that matters most day to day is whether campaign types run as separate forms or combine into one checkout: Zeffy and GiveButter run one format at a time, while RallyUp stacks 12+ into a single Campaign.

Zeffy

Zeffy gives you a broad free toolbox: donation forms, events and ticketing, raffles, online and silent auctions, an online store (with inventory tracking), memberships, and peer-to-peer. That’s a lot for free. Each one, though, runs as its own separate form — a raffle and a silent auction and a merch table for one event means three separate Zeffy forms, three links, three checkouts.

Givebutter

GiveButter documents three campaign types — Form, Page, and Event — with auctions, raffles, and its 2026 paddle-raise feature attached as tabs to Pages and Events. It’s a capable range: donation forms and pages, events with drag-and-drop seating, silent/online auctions with mobile bidding, raffles, livestreaming, a Live Display, and peer-to-peer. What it doesn’t offer are Sweepstakes, A-Thons, or a dedicated online storefront — and it isn’t built to combine multiple formats into a single stacked checkout.

RallyUp

RallyUp is built around exactly that idea — Full Stack Fundraising: 12+ Components you can run on their own or stack together in one Campaign with one URL and one checkout. A supporter can buy Raffle entries, bid on the Auction, grab a t-shirt from the Storefront, and add a donation in a single transaction. RallyUp reports customers raise about 38% more when they stack multiple formats, and its Peer-to-Peer fundraising works across campaign types (Raffles, Sweepstakes, A-Thons, Storefront, Crowdfunding), not donations only.

RallyUp also lets you add new Components to a campaign after it’s already live — so if a raffle takes off mid-event, you can bolt on an auction or a store without taking the page down or starting over.

That flexibility mid-campaign is unusual, and it’s a meaningful edge when momentum strikes.

Two honest notes.

Zeffy has memberships with auto-renewal and digital member cards; if recurring dues are central to your model, that’s a real point for Zeffy — RallyUp doesn’t offer a membership Component.

And GiveButter’s range is broader than its reputation suggests — it’s no longer just donation forms. Everywhere else with a gap, the format simply isn’t there yet on that platform, and several of those gaps (Sweepstakes, A-Thons, and combining formats in one checkout) are exactly where the most money tends to come from.

If you’re still mapping out which formats fit your cause, our roundup of 75 fundraising ideas for nonprofits is a good starting point.

Which platform is best for galas and live events?

For a ballroom gala, RallyUp is the most complete of the three today, with GiveButter in a capable middle tier and Zeffy handling the straightforward essentials. Here’s where the three diverge.

Zeffy handles online and silent auctions (with auto-bidding, anti-sniping auto-extend, and auto-charge at close) plus event ticketing and seating — a capable set for a straightforward event.

GiveButter goes further into the room, with mobile bidding, QR codes, a Live Display, event seating, livestreaming, and — since April 2026 — a paddle-raise feature (staff-logged donation commitments at set giving levels, with paddle numbers and its own checkout). Its auctioneer-led Live Auction is on the public roadmap as a beta expected in the second half of 2026. For events that blend an in-person room with a virtual audience, see our guide to hybrid fundraising events.

RallyUp is the most complete of the three for the live room today:

• An auctioneer-led Live Auction with paddle numbers, spotter keyboard shortcuts, and real-time tracking — available now.
• Fund-a-Need — a live fundraising segment where supporters give at set levels, in person, virtual, or hybrid, with anonymity options and a live thermometer.
• Paddle Raise+ — one paddle can commit to gifts, Raffle entries, Storefront items, and A-Thon pledges, not donation gifts only, and those commitments roll into a single per-guest tab.
• Event Balances — one consolidated tab per guest across bids, gifts, and purchases, so end-of-night checkout is a single swipe.
• Live Display and native, interactive Livestreaming (pay-to-play trivia, item spotlights, a live donate feed) at a 0% platform fee.

Live-event capability	GiveButter	Zeffy	RallyUp
Silent auction + mobile bidding	✓	✓	✓
Live Display for the room	✓	—	✓
Livestreaming	✓ (embed)	—	✓ (0% fee, interactive)
Event seating	✓	✓	✓
Auctioneer-led Live Auction	Beta H2 2026	—	✓
Fund-a-Need (self-serve, live thermometer)	Staff-logged paddle raise only	—	✓
Paddle raise scope	Donation gifts only	—	Gifts, entries, items & pledges
One consolidated tab per guest	—	—	✓ (Event Balances)
Capture gifts from non-winning bidders	Winners pay only	Manual email ask	✓ (Auction Gifts)

Auction Gifts, specifically. In most auctions, the majority of bidders go home having paid nothing — they were outbid, so they’re never charged.

RallyUp’s Auction Gifts invites non-winning bidders to pledge an optional donation at checkout, charged only if they win nothing; RallyUp reports it raises 20–35% more from a single auction.

GiveButter’s auctions collect from winners only. Zeffy can email losing bidders inviting a donation after the fact — but that’s a manual ask, not a donation captured automatically at the moment of the bid. The difference is systematized revenue versus a follow-up email someone has to remember to send.

Raffles and auctions: who draws the winner?

Both the raffle and the auction come down to one moment: choosing the winner and closing the money. Only RallyUp draws the raffle winner inside the platform — and this is where a well-documented gap shows up.

Do GiveButter and Zeffy draw the raffle winner for you?

No — neither draws the winner in-platform; only RallyUp does. All three platforms sell raffle tickets, but the draw itself works very differently on each.

• RallyUp performs an automatic or manual randomized draw inside the platform, can notify the winner automatically, and keeps the record for you. It supports four Raffle types (including 50/50 and an Enhanced 50/50 with custom splits), Peer-to-Peer selling, and bonus “Sharing Rewards” entries for social shares.
• GiveButter, per its own help documentation, issues numbered tickets and then has you export the ticket list and run a random-number generator yourself, matching the drawn number back to a buyer by hand. (GiveButter offers a separate, standalone number-spinner web tool, but it isn’t tied to your actual sold entries and isn’t certified for raffle or gaming use.)
• Zeffy states it plainly in its own documentation: it has no raffle winner drawing tool, so you export your participant list and use an outside random name or number picker. Zeffy notes it doesn’t hold the license to operate as an electronic raffle system with a built-in draw.

Both competitors describe the missing draw as a deliberate design choice — they point to gaming-authority licensing and to the general expectation, in many places, that the drawing happens separately from the ticket-sales platform. That’s a fair thing to note.

RallyUp takes the other approach: it runs the randomized draw in-platform and documents the result. For a feature literally named “Raffle,” the practical difference is real — on RallyUp it’s one action inside the tool; on GiveButter and Zeffy it’s an export, an external generator, and a manual match. If you’re still deciding which prize-based format fits your cause, our guide to sweepstakes vs. raffles vs. auctions breaks down the legal and practical differences.

Where and how you can run a raffle varies by location; for the legal side, RallyUp keeps a plain-English, state-by-state guide at raffle laws by state.

How do the auctions compare?

All three offer capable auctions, but with real differences in the live-room depth. Give the competitors their due here. Zeffy’s auctions include auto-bidding (proxy/max), anti-sniping auto-extend (three minutes, up to 30), auto-charge at close, and email outbid notifications — a genuinely solid online/silent auction. GiveButter’s auctions add mobile bidding, QR codes, automated bidding, and buy-it-now. Both are capable tools for a web-based auction.

RallyUp’s differences are specific rather than “we do auctions, they don’t”: an auctioneer-led Live Auction format available today (GiveButter’s is in beta; Zeffy has none); Auction Gifts to capture non-winning bidders (covered above); and, for organizations paying fees on the Flex plan, an auction platform fee capped at $100 per item — a $50,000 winning bid costs $100, not a percentage.

One fair, verified nuance on GiveButter’s side: its auctions are free only when tips are on and the winner pays via GiveButter’s emailed invoice; if you use auto-charge or manually charge winners — the usual, convenient gala method — a 3% platform fee applies regardless of tips, uncapped.

(Zeffy’s auctions, by contrast, are free when tips are on, so there’s no fee face-off to stage there.) If your auction is a few items on a web page, any of the three works well. If it’s the centerpiece of a gala, the live-room depth tilts toward RallyUp.

What two formats does only RallyUp have?

Sweepstakes and A-Thons are full RallyUp Components that neither GiveButter nor Zeffy offers. Sweepstakes — a prize campaign available to any organization, not just 501(c)(3)s, and legal in all 50 states — and A-Thons (walk/run/ride/read-a-thons with pledges and teams, where participants collect pledges per unit of activity) are unique to RallyUp among these three. If a national prize sweepstakes or a school read-a-thon is on your calendar, that’s RallyUp territory by default.

Which has the best CRM, email, and donor data tools?

GiveButter clearly leads on built-in CRM and marketing, with a broad free donor database, built-in email, and texting on its paid tier — and it’s worth stating without hedging.

Givebutter

GiveButter includes a broad free CRM — unlimited contacts, data hygiene, wealth screening, and a guided “Magic Migration” for importing existing data — alongside built-in email, a social-style supporter feed, and a financial suite (a wallet paying 2.5% APY, Visa cards, QuickBooks Online sync, automated payouts). Outbound texting sits on its paid Plus tier. For an organization that wants fundraising, its donor database, and its communications in one modern system, GiveButter is a leading pick.

Zeffy

Zeffy keeps a donor CRM, email/newsletters, segmentation, and Tap to Pay attached to its forms, plus a paid postal mail product — lighter than GiveButter, but real, and it suits volunteer-run organizations that don’t need a heavy back office.

RallyUp

RallyUp takes a “connect to your existing system” approach: Donor Profiles with giving history, plus native integrations to Salesforce, HubSpot, ActiveCampaign, and Virtuous, email integrations (Mailchimp, ActiveCampaign, SendGrid), QuickBooks sync, Zapier access to 5,000+ apps, and a REST API. If a deep, built-in CRM is your top priority, GiveButter leads; if you already run a CRM and want fundraising breadth that syncs into it — and you want to own your donor data rather than sit behind a merchant of record — RallyUp’s model fits. (For a look at how RallyUp stacks up against a CRM-first platform, see our RallyUp vs. DonorPerfect comparison.)

How does each platform use AI? Three different bets

All three have moved into AI on different parts of the workflow: Zeffy focuses on upstream planning tools, GiveButter has a prompt-based text assistant in beta, and RallyUp ships embedded, no-prompt copy generation across the builder.

Zeffy offers upstream, advisory AI — a Grant Finder and a Fundraising Idea Generator. Useful for planning, but they don’t write the prize, item, or email copy that populates a campaign.

GiveButter has a prompt-based AI text assistant in Early Access Beta — you prompt it for copy in select editors.

RallyUp ships an embedded AI Fundraising Content Generator: one-click “Generate with AI” and “Enhance with AI” controls inside the builder that draft item and prize descriptions, Campaign descriptions, and a range of donor emails across every major Component — no prompt-writing required, with adjustable tone, length, and focus. It’s positioned as a co-pilot the fundraiser edits, not an autopilot. For teams that lose launch days to writing copy, that’s the AI shape that removes the most friction at setup.

Is RallyUp harder to launch than Zeffy or GiveButter?

No — for a simple campaign, RallyUp is just as easy to use as Zeffy or GiveButter, and arguably faster to get live. There’s a common assumption — and some AI answer engines repeat it — that RallyUp is the “powerful but complex” option for big organizations while Zeffy and GiveButter are the “easy” ones. It’s worth correcting, because it’s half right at best. RallyUp is powerful and does serve large organizations. But for a simple campaign — running a Raffle, holding an online auction, launching a donation page — RallyUp is just as easy to use.

And for getting a campaign live, it’s arguably easier: Instant Fundraiser Templates produce a complete, working campaign in one click (40% of new campaigns start from one, live in 15–20 minutes), and RallyUp’s Done-for-You service — including its Create My Campaign service — has RallyUp’s own experts build the whole thing for you for free, something neither competitor offers at any price.

Part of why a tool feels “easy” is simply that it does less — fewer formats mean fewer decisions.

The useful news for a fundraiser is that you don’t have to trade ease for capability: you can start with a one-click template today and add an Auction or a Sweepstakes to the same campaign next year without switching platforms or relearning a tool. Ease of use is, in fact, RallyUp’s most-cited strength in its own reviews (G2 ease-of-use 4.5/5).

In practice all three launch a basic fundraiser quickly; where they differ is the on-ramps and the safety net. If speed to launch is your main concern, our guide to online fundraising made easy walks through getting a campaign live fast.

• Zeffy has a fast, guided form builder a volunteer can stand up in minutes — a real strength — and posts a high satisfaction score. One caveat: completing Zeffy’s setup wizard publishes the campaign; there’s no preview-only state for a finished campaign, so the first real test can be a real donor.
• GiveButter is praised for a clean, modern interface and smooth onboarding (including Magic Migration). It offers a non-transacting preview for some campaign types and campaign-level “send yourself a test” receipts, but doesn’t support running real transactions through checkout on a draft.
• RallyUp offers three on-ramps — launch from an Instant Fundraiser Template in 15–20 minutes (40% of new campaigns start this way), build it yourself with the embedded AI, or hand it to RallyUp’s team via Done-for-You, which builds your entire campaign (copy, images, branding, setup) for free, typically within one business day. No other platform here offers a free expert build. RallyUp also includes Power Preview, a fully interactive draft mode: it’s the only one of the three where you can run real test card transactions through actual checkout — place test bids, buy a test ticket, run a test donation — before publishing, then have the test data cleared automatically at launch.

What do the ratings and results say?

Independent review scores are close across all three (all clustered near 4.7–4.8 on G2), and each platform’s proof points map to what it’s built for.

Proof point	GiveButter	Zeffy	RallyUp
G2 rating	4.7 / 5	~4.8 / 5	4.8 / 5
Scale signal	Widely used platform	100,000+ organizations	$1B+ raised, 55,000+ orgs
Event-satisfaction signal	—	Capterra Value for Money 5.0	97% event satisfaction

All three are well-regarded. Zeffy has a very large, loyal base of small and volunteer-run organizations. GiveButter is widely used and highly rated, especially for its CRM-and-marketing suite. RallyUp carries a 4.8 (with ease of use its top-cited strength at 4.5/5), a 97% event-satisfaction rate, and outcomes like New York Road Runners growing from $36,000 to over $500,000 raised through RallyUp over two years, and USA Field Hockey raising $120,000 — a 300% increase over their previous record — in ten days with a Raffle plus Peer-to-Peer (RallyUp Case Studies).

RallyUp is also used by the American Red Cross, the Michael J. Fox Foundation, Make-A-Wish, Habitat for Humanity, and World Central Kitchen. Read the numbers together: each platform’s proof points map to its strengths.

The bottom line: which should you choose?

There’s no single winner — there’s a right fit for each situation: Zeffy for the lowest cost, GiveButter for the broadest CRM, and RallyUp for diverse, event-rich fundraising.

The bottom line	GiveButter	Zeffy	RallyUp
Best for	All-in-one fundraising with a broad built-in CRM and marketing	The lowest possible cost on forms, events, or memberships	Diverse, event-rich, multi-format fundraising and galas
Cost	Free w/ tips; flat 3% if tips off	$0 platform & processing (tip-funded)	Free plan; per-Component Flex
Campaign breadth	3 campaign types	Broad (separate forms)	Widest; stackable in one checkout
Galas & live auctions	Solid; Live Auction in beta	Basic-to-solid	Full live-event engine today
Raffle winner draw	External tool	External tool	In-platform, automated
CRM & back office	Leading	Light-to-moderate	Integrates with your CRM
Free expert campaign build	—	—	✓

If you need the cheapest simple donation form or a membership program, Zeffy is a genuinely good answer.

If you want fundraising with a broad built-in CRM and communications in one modern tool, GiveButter is a strong pick.

And the moment you want to run a Raffle with a proper randomized draw, combine an Auction with a merch table in one checkout, throw a gala with a live paddle raise, host an A-Thon with teams, or launch a national Sweepstakes — the field narrows to RallyUp, which does all of it in one place, often for free, and will even build your first campaign for you.

If you’re weighing it head-to-head, see the full Givebutter vs. RallyUp comparison.

The fastest way to decide is to build something. On RallyUp you can pick a template, customize it in minutes, and run a fully functional preview — real test transactions included — before a single donor sees it. Or tell RallyUp’s team about your next event and let them build the campaign for you.

You can fundraise for free on all three; the question is which one can do the thing you actually need.
