RallyUp vs.
OneCause 

OneCause publishes entry-tier pricing: $2,995/year for the Professional Auction & Event package, or Pay-As-You-Go starting at $200 with a capped 5% pay-later fee on funds raised, while its Enterprise and Nationals tiers are quote-only. Payment processing is reported on top of that, up to 4.35% + $0.35 per transaction depending on the processor. RallyUp has no subscription and no contract at all: its free plan carries a 0% platform fee funded by optional donor tips, and Flex charges per Component — 2.9% for Events and Store, 4.9% for Auctions, A-Thons and Crowdfunding, 6.9% for Raffles and Sweepstakes, and 0% for Donation Pages, Peer-to-Peer and Livestreaming, plus processing of 2.9% + $0.30 (1.9% + $0.30 for ACH). See RallyUp pricing.

No. OneCause has no free plan and no trial period — the cheapest documented route in is Pay-As-You-Go from $200 with a capped 5% pay-later fee, and the Professional Auction & Event package is $2,995/year. RallyUp’s free plan has a 0% platform fee funded by optional donor tips, and RallyUp Donation Pages go further still: no platform fee and no donor tipping required at all. There is nothing to sign and nothing due before your first dollar is raised, and RallyUp’s fundraising experts will build your first campaign free, usually within one business day.

OneCause is a capable event platform with a track record going back to 2008 — ticketing, mobile bidding, live and silent auctions, Fund-a-Need appeals, scoreboards, assigned seating, couples check-in and an optional on-site event staff are all real strengths. RallyUp runs the same gala-grade infrastructure — auctioneer-led Live Auction, Paddle Raise+, Fund-a-Need and Live Display — and adds Event Balances, which puts each guest on one tab all night that settles in a single charge, with line-free checkout that is instant or fully automatic. OneCause documents guest carts and self-driven checkout, but not a single end-of-night charge per guest. RallyUp also adds Auction Gifts, which lets non-winning bidders pledge a gift charged only if they win nothing and lifts auctions 20–35% on average, and it does all of this with no annual license and no sales process.

OneCause supports raffles with an automated randomized in-platform draw, but it documents no 50/50 format, no configurable split and no live prize total, and it is not a dedicated raffle platform. RallyUp runs four raffle formats natively — Single-Prize, Multi-Prize, 50/50 and Enhanced 50/50 where you set your own split, such as 60/40 — performs the randomized drawing inside the platform with automatic winner notification and retained records, and shows the winner’s live prize total on the campaign page as entries sell. Raffles are 6.9% on RallyUp’s Flex plan and carry no platform fee on the free plan. Whether a raffle is permitted — and what’s required to run one — depends on several factors, not just your state; it’s the organizer’s responsibility to research the applicable rules and confirm legality for their own situation, including with the relevant authorities and their own legal counsel as needed. RallyUp doesn’t provide legal advice or confirm that any campaign is legal.

Only partly. OneCause’s peer-to-peer is limited to crowdfunding and donations — it is not available across raffles, sweepstakes, a-thons, ticketing or store campaigns — and A-Thons, sweepstakes and an online store are not available on the platform at all. RallyUp runs Peer-to-Peer across Raffles, Events & Ticketing, Sweepstakes, A-Thons, Crowdfunding, Store and Livestreaming, and has a dedicated A-Thon Component with pledges, milestones and Peer-to-Peer built in. Peer-to-Peer carries a 0% platform fee on RallyUp’s Flex plan, and any Component can be added to a campaign that is already live without rebuilding it.

For organizations that want gala-grade event tooling without an annual license, RallyUp is the strongest OneCause alternative: it runs Live Auction, Paddle Raise+, Fund-a-Need, Live Display and Event Balances, plus the formats OneCause does not offer — Sweepstakes, A-Thons, an online Store and native Livestreaming with fundraising games. RallyUp is rated 4.8/5 on G2 from 115 reviews, and 4.5/5 for ease of use on Capterra, with most organizers launching a polished campaign in about 15 minutes from an Instant Fundraiser Template. OneCause requires an annual subscription at $2,995/year or a paid Pay-As-You-Go commitment before you launch; RallyUp has no contract, and its experts will build the campaign for you free at Create My Campaign.
