Donorbox vs. OneCause vs RallyUp: 2026 Comparison

Most nonprofits arrive at this comparison with one campaign in mind: a raffle, an online auction, a donation page, a walk-a-thon, or a gala. RallyUp is genuinely easy to build and launch for exactly that job, and it is free to fundraise on Donation Pages.

Donorbox is a donation-first platform with recurring giving, memberships, crowdfunding, and peer-to-peer tools.

OneCause is a sales-led event platform with real auction, raffle, and gala capability. All three are known for being easy on screen. Only one of them can run every format in this comparison.

The stakes are higher than they were two years ago. Online revenue for the average nonprofit rose 15% in 2025 (M+R Benchmarks 2026). December alone delivered 37% of all annual online revenue. So much of the year lands in one month. Therefore the platform you pick has to support your format on the first try.

This comparison is openly pro-RallyUp, and every claim in it is sourced. Each figure comes from the platform’s own website, pricing page, help documentation, or acceptable-use policy, plus published review data.

Where a platform’s own pages contradict each other, we say so rather than picking the flattering number. Pricing and features are current as of August 2026.

What Is the 60-Second Verdict on Donorbox vs. OneCause vs. RallyUp?

Choose RallyUp. It is easy to build and launch for a single campaign, and it is free to fundraise on Donation Pages. It is also the only one of the three that runs Raffles, Sweepstakes, Auctions, A-Thons, and a full gala.

Donorbox is a reasonable pick if a recurring-giving form is genuinely the whole job. OneCause is worth a demo only if you want a sales-supported build for one flagship gala and are comfortable with a contract.

RallyUp offers the widest set of separately configurable formats of the three — and it stays easy while doing it. Raffles, Sweepstakes, Auctions, A-Thons, Storefront, Donation Pages, and live-event tools each run as their own Campaign, or combine into one. Ease of use is RallyUp’s most-cited review strength, at 4.5/5 for ease of use on Capterra.

There is no contract, no subscription, and a $0-RallyUp-platform-fee option; payment-processing fees still apply, as they do everywhere. It is not a full donor CRM, though — RallyUp offers Donor Profiles and CRM integrations rather than replacing one.

Donorbox is the most donation-focused of the three, and its ease reputation is real but narrow — it is easy at building a single donation form, not at running a fundraising program. It offers recurring giving, memberships, crowdfunding, peer-to-peer fundraising, and lightweight event ticketing. However, it has no native Raffle, Sweepstakes, or Auction product.

Its Acceptable Usage Policy restricts “games of skill or chance … or sweepstakes.” On top of that, its platform fee of 2.95%–3.95% applies on every plan, including the free one. No Donorbox configuration reaches a genuine $0 platform fee (Donorbox pricing).

OneCause is a sales-led event platform with genuine gala tenure — credit where it is due, and that tenure only matters if one flagship in-person event is your entire fundraising year. It offers Live and Silent Auctions, in-platform raffles with automated winner drawing, and Fund-a-Need-style live appeals. It publishes entry-tier pricing: a pay-as-you-go option from $200 and a $2,995/year Professional Auction & Event package (OneCause plans).

Even so, getting onto the platform runs through a demo request rather than instant signup. Its Enterprise and Nationals tiers stay quote-only, and there is no $0-platform-fee tier. Reviewers also report a steeper learning curve.

Which Platform Wins on Each Buying Priority?

Each platform wins a different question, so match the platform to your single most important requirement.

• Easiest path to a finished, launchable campaign: RallyUp — an Instant Fundraiser Template arrives with design, Components, and checkout already assembled, or RallyUp’s experts build it for you free.
• Lowest advertised cost to open a Donation Page: RallyUp — $0 RallyUp platform fee, no donor tipping required. Donorbox charges 2.95%–3.95% on every plan.
• Best end-of-night checkout at a live event: RallyUp — Event Balances settles a guest’s whole night into one tab and one charge.
• Widest format range in one place: RallyUp, the only one of the three that combines online-only formats with live-event tools in a single Campaign.
• Deepest donor CRM out of the box: Donorbox, whose Premium tier adds Salesforce NPSP sync — useful if you want your fundraising tool to double as your database.

Sweepstakes note: RallyUp makes its Sweepstakes Component available beyond 501(c)(3) nonprofits. Even so, eligibility, free-entry requirements, and state or local restrictions still apply. Confirming legality for a specific situation is the organizer’s responsibility — see the FAQ below.

What Does Each Platform Actually Cost in 2026?

RallyUp is the only one of the three that is free to fundraise: a $0 platform fee on its Free plan, plus processing. Donorbox charges 2.95%–3.95% on every plan, including its free one, plus processing. OneCause charges either 5% of funds raised or $2,995 a year flat. In short, only one of these three ever reaches a genuine $0 platform fee.

Cost element	Donorbox	OneCause	RallyUp
Subscription / upfront	$0 to start; $150/mo Pro; custom Premium	$0–$500 down (pay-as-you-go) or $2,995/yr flat	$0 Free plan; no subscription at any tier
Platform / performance fee	2.95% or 3.95% on Standard; ~1.75–2% Pro; ~1.6% Premium	5% of funds raised, capped (cap not published); $0% on flat package	$0 on Free; per-Component Flex fees of 2.9–6.9%
Payment-processing fee	Stripe 2.2% + $0.30, or PayPal 1.99% + $0.49	Not published on pages reviewed	1.9–2.9% + $0.30
Per-item fee caps	None identified	Not identified	Auction fee capped at $100/item on Flex
Donors can cover fees	Not identified	Not identified	Yes — organizer, donor-covered, or flat convenience fee
Contract required	No	Typically yes for the annual package	No
Quote-based or variable	Pro/Premium custom pricing	Pay-as-you-go minimum and fee cap vary or are unpublished	Enterprise only

How Does RallyUp’s $100 Auction Fee Cap Work?

RallyUp’s Flex Auction fee is 4.9%, capped at $100 per item. The cap only changes the math on higher-value lots. For example, a $500 item is billed its actual 4.9%, or $24.50. The fee reaches $100 once an item sells for about $2,041. After that, a $10,000 item and a $50,000 item both land at the same $100.

Can You Run the Campaign You Want To?

Only RallyUp supports every major fundraising format in this comparison, including Raffles, Sweepstakes, A-Thons, and Storefront alongside live-event tools. Donorbox and OneCause are each strong in a defined lane instead.

Campaign type	Donorbox	OneCause	RallyUp
Donation Pages / giving sites	Yes	Yes	Yes — $0 fee, no required tipping
Crowdfunding	Yes	Not a distinct product	Yes
Raffle	Not offered	Yes — within Auction & Events	Yes — 4 formats, P2P entry selling
Sweepstakes	Not offered	Not offered	Yes — eligibility rules apply
Online / Silent Auctions	Not offered	Yes	Yes
Live Auction (auctioneer-led)	Not offered	Yes	Yes
Peer-to-Peer	Yes	Yes	Yes — spans Raffles, Sweepstakes, A-Thons, Storefront
A-Thons (per-unit pledges)	Not offered	No — Runs Walks Rides collects flat donations, not per-mile or per-lap pledges	Yes
Storefront / merch	Not offered	Fixed-price items in an event	Yes
Ticketing & Registration	Yes	Yes	Yes
Fund-a-Need / Paddle Raise+	Not offered	Fund-a-Need-style appeals	Yes
Online-only + live-event formats in one checkout	No	Event-day activities only	Yes — 12+ Components, one URL

Organizations that stack multiple campaign types into a single RallyUp Campaign report raising 38% more on average. That lift is tied to combining formats in one Campaign, not to switching platforms generally.

Why Can’t Donorbox Run a Raffle?

Donorbox’s gap on Raffles and Sweepstakes is a matter of policy, not a missing feature. Its Acceptable Usage Policy restricts “games of skill or chance … or sweepstakes.” It also bars any activity that pairs an entry fee with a prize.

The policy does not speak to auctions directly. Still, Donorbox markets no auction product of any kind. If a paid raffle is on your calendar, start with a platform that treats raffles as a first-class Campaign type. You can also compare dedicated tools in our roundup of the best online raffle websites.

How Good Is OneCause’s Raffle Functionality?

OneCause’s raffle capability is real, not an add-on line item. Its materials describe multiple simultaneous raffles, randomized in-platform drawing, and tiered ticket bundles (OneCause Auction & Event plans). The distinction from RallyUp is product shape rather than missing functionality.

OneCause delivers raffles inside its Auction & Events product.

RallyUp, by contrast, offers Raffles as their own Component in four named formats, runnable without a full event package. If you are still weighing which format fits your prize and your state rules, our guide to sweepstakes vs. raffles vs. auctions breaks down the legal and operational differences.

Format choice pays off when it matches the audience. USA Field Hockey, for example, used RallyUp to raise $120,000 — a 300% increase over their previous fundraising record (RallyUp case study).

Which Platform Is Best for Galas and Live Events?

RallyUp is the best choice for a gala, and Donorbox cannot run one at all, because it has no auction or live-event tooling.

RallyUp’s gala and event tools are easy to build without a sales-led contract, and RallyUp’s experts will build the campaign for you free.

OneCause is the only real alternative here, and its depth is genuine — but it comes through a demo request and a paid plan.

One tab all night, one charge. RallyUp’s Event Balances keeps a single running tab per guest across bids, raffle entries, sale items, and pledges. Automated Checkout then settles it. Line-free checkout, instant or automatic. Put simply, it gives guests their night back instead of handing them a queue at the door.

The results show up in the numbers. 90% of payments complete in under a minute, and 75% of guests check out on their phones. Teams also report 50% fewer post-event follow-ups. For guests on auto-checkout, the checkout line takes 0 minutes — there is nothing to stand in.

The rest of the RallyUp gala set is equally complete. It includes auctioneer-led Live Auctions, Fund-a-Need, Paddle Raise+, and Live Display. Notably, Paddle Raise+ covers Raffle entries, sale items, and A-Thon pledges by paddle, not only donation gifts.

OneCause does have long-standing depth in this room. Its Auction & Events product covers Live Auctions with paddle numbers, a Spotter Tool, Silent Auctions, and Fund-a-Need-style appeals.

That said, the access model is the catch: a demo-request process and no $0 tier. Its own pages also disagree on the pay-as-you-go minimum. One says $200; another says as little as $500 down. The pay-as-you-go fee cap amount is not published either.

One honest caveat: we could not find public OneCause documentation describing an identically named, single cross-activity running-tab feature. OneCause’s materials point to card-on-file capture and split-payment billing instead.

Treat this as a difference in how each platform documents checkout rather than a confirmed capability gap. If your event runs partly online, our guide to hybrid fundraising events covers how the two halves connect.

How Do You Choose Between Donorbox, OneCause, and RallyUp?

Choose by working from your hardest campaign backwards, in six steps, rather than starting from the pricing page.

1. Name the hardest campaign you must run this year. Write down the single format that would break your calendar if the platform could not support it — a gala, a raffle, a walk-a-thon, or a year-round donation page.
2. Check whether each platform actually supports that format. Read the acceptable-use policy, not just the feature list. Donorbox’s policy, for instance, rules out raffles and sweepstakes outright.
3. Price the format, not the plan. Multiply your realistic annual raise by each platform fee, then add processing on top. A “free” plan with a 3.95% fee costs more than a $0-fee plan at your volume.
4. Decide how fast you need to launch. If your event is under six weeks away, rule out any platform whose onboarding starts with a demo request and a contract.
5. Confirm your donor-data and support requirements. Ask whether you need a full CRM or CRM integrations, and check whether phone support is included at your tier.
6. Test the full checkout before you announce. Run a real test transaction end to end, including any auction bid or ticket purchase, and only then send the launch email. RallyUp’s Power Preview does exactly this before a Campaign is published.

Which Platform Has the Best AI Tools?

RallyUp’s AI Fundraising Content Generator is the only one free to every user, with no prompt writing required. It drafts campaign copy directly inside the builder on every plan, including Free. Donorbox’s Jay·AI writes marketing copy, but only on paid plans and only from your prompts. OneCause’s AI is scoped to auction items. Treat all three as a co-pilot for a draft, though — you stay the editor.

AI capability	Donorbox (Jay·AI)	OneCause (Auction AI)	RallyUp (AI Fundraising Content Generator)
What it does	Drafts social posts, emails, win-back letters, reports	Recommends and sorts auction items; writes item descriptions	Drafts prize, item, campaign, and Participant Center copy plus six donor email types
Prompts required	Yes — chat-style	Not applicable	No — one-click Generate/Enhance
Plan availability	Pro, Premium, CRM only	Included with auction/event product	All plans, including Free
Scope	Marketing messaging and reporting	Auction/event experience	Every supported field in the campaign builder

How Fast Can You Launch on Each Platform?

RallyUp is the fastest way to get a real campaign live. An Instant Fundraiser Template takes about 15–20 minutes, or RallyUp’s experts build it free. Donorbox can publish a single donation form in minutes, though that is one form, not a campaign.

OneCause, by contrast, starts with a demo request and a sales process. Speed matters more than it looks, because 43% of online donations were made on a mobile device in 2025 (Nonprofit Tech for Good). Put simply, a campaign that is not live is not shareable.

Donorbox is quick at the narrow thing it does. Its reviews cite ease of setup often, and a single donation form can go live the same afternoon. Even so, a form is not a raffle, an auction, or a gala.

OneCause’s onboarding, by contrast, runs through a demo and a sales conversation. That is a reasonable trade for a dedicated Auction & Events build. Even so, it means a longer path to a first live campaign.

RallyUp’s Instant Fundraiser Templates arrive with design, Components, and checkout already assembled. Roughly 40% of RallyUp campaigns use a template, and a template campaign can be live in about 15–20 minutes.

If you would rather not touch the builder at all, RallyUp’s experts will build it free through Create My Campaign. That usually takes about one business day. The broader Done-for-You service extends that help further. Neither Donorbox nor OneCause offers a free equivalent.

Before a Campaign goes live, RallyUp also offers Power Preview, which runs real test card transactions and test bids through checkout. We found no public documentation describing an equivalent interactive test mode on Donorbox or OneCause.

What About CRM, Donor Data, and Support?

Donorbox has the deepest built-in donor management of the three. OneCause organizes donor data around event-day handoffs. RallyUp, meanwhile, pairs native Donor Profiles with integrations to dedicated CRMs.

Donorbox includes donor-management features and a donor portal in its core plans, plus broad country reach at 96+ countries. A fuller CRM feature set, including Salesforce NPSP sync, sits in the Premium tier rather than across all plans. Notably, Donorbox does not offer phone support at any tier — its help center states support is email only.

OneCause’s donor tools are built around guest profiles, card capture at registration, and supporter activity across events. They are not built for general CRM depth. Its pricing pages advertise phone, chat, and email support at no extra cost, plus a 24/7 AI Guide.

RallyUp offers native Donor Profiles plus integrations with Salesforce, HubSpot, ActiveCampaign, Virtuous, Mailchimp, and others. It does not function as a full CRM itself.

On support, RallyUp’s approach is deliberately different: no bots, only humans. Every plan, including Free, gives you full access to RallyUp’s fundraising experts by chat or email, with phone and Zoom available.

By contrast, OneCause routes first-line questions through a 24/7 AI Guide.

On international reach, RallyUp advertises 135+ currencies against Donorbox’s 52+, while Donorbox’s 96+ countries outpaces RallyUp’s 47+. If a CRM-first platform is what you actually need, our RallyUp vs. DonorPerfect comparison covers that trade-off directly.

What Do Ratings and Scale Numbers Say?

RallyUp holds the highest G2 rating of the three at 4.8/5, and ease of use is the strength reviewers cite most. OneCause follows at 4.7/5. Donorbox sits at 4.6/5, with by far the largest review volume. Figures below are as of August 2026.

Metric	Donorbox	OneCause	RallyUp
G2 rating	4.6/5	4.7/5	4.8/5
G2 reviews	~1,500	~510	~115
Capterra rating (reviews)	4.8/5 (~625)	Not comparable	4.7/5 (~59)
Ease of use (Capterra)	—	—	4.5/5 — most-cited strength
Scale claimed	100,000+ nonprofits; $4B+ raised	14,000+ organizations; $8B+ raised	55,000+ organizations; $1B+ raised
Most-cited strength	Ease of setup; recurring giving	Gala/auction depth; support	Ease of use; breadth of campaign types

Review counts and scale figures are not directly comparable, because each platform has a different customer base, pricing model, and time in market. Volume is not the same as satisfaction, though. RallyUp holds the highest rating of the three. Ease of use is also the strength reviewers name most often, at 4.5/5 on Capterra.

The Bottom Line: Which Should You Choose?

Choose RallyUp. It is easy to build and launch for a single campaign, and it is free to fundraise on Donation Pages. It also runs every format in this comparison: Raffles, Sweepstakes, Auctions, A-Thons, and a full gala.

Choose Donorbox only if a recurring-giving form is genuinely the whole job.

Choose OneCause only if a single flagship gala is the whole job and a contract is acceptable.

Key Takeaways

• RallyUp is easy to build and launch: 40% of campaigns use a template, ease is the top-cited review strength at 4.5/5 on Capterra, and RallyUp’s experts will build your first campaign free.
• Donorbox charges a platform fee on every plan, including the free one, at 2.95%–3.95% — no Donorbox configuration reaches a genuine $0 platform fee.
• Donorbox cannot host a raffle, sweepstakes, or auction — the first two are prohibited by policy, the third is simply not built.
• OneCause publishes prices but not a free path: pay-as-you-go from $200 with a capped 5% fee, or $2,995/year flat, both reached through a demo.
• RallyUp is the only one of the three with a $0 platform fee on Donation Pages and no donor tipping required there.
• Event Balances is a category of one: one tab all night, one charge, with 90% of payments completing in under a minute.
• When you are ready to grow, stacking pays: organizations that combine multiple campaign types in one Campaign raise 38% more.

Methodology: Donorbox and OneCause pricing, features, and policies are drawn from their own websites, pricing pages, and help or policy documentation. G2 review data is included as well, current as of August 2026. Some OneCause figures could not be cross-verified against a second OneCause source. These include the pay-as-you-go starting minimum, the fee cap amount, and specific event-day feature names. We have flagged those explicitly rather than presenting them as certain. Pricing and features change on all three platforms, so verify current details directly with each before making a purchasing decision.
