Zeffy vs. Givebutter: The Real Tradeoffs Behind 'Free'

Both of these platforms say they cost the organization nothing. Both are funded by donor tips. But the way each one asks your donors for that tip feels different at the checkout, and the feature sets are not interchangeable. The "free" is real; it just lands on someone.

Quick answer

  • Both are "free" to the org, funded by tips your donors pay.
  • Givebutter is deeper on events and peer-to-peer; Zeffy is broader and barer.
  • The hidden cost is what the tip prompt does to your donors’ wallets.

Zeffy and Givebutter both lead with the same headline: free for your nonprofit. And both are telling the truth, in the narrow sense that the platform does not bill your organization. The money comes from donor tips instead, an optional extra added on top of the gift at checkout.

That shared model hides two pretty different products. Givebutter is a full events-and-peer-to-peer platform that happens to be tip-funded. Zeffy is a broad, barebones, genuinely-zero-fees tool with a more insistent tip prompt. The right pick depends on what you are running and how comfortable you are asking your donors to subsidize the software.

Here is the real comparison, including the part nobody puts in the marketing: what those tip prompts cost the people giving you money.

How "free" actually works on each

Neither of these is free in the sense of "no money changes hands." Card processing still happens, roughly 2.9% + 30¢ on both. The trick is who pays for the platform on top of that.

Zeffy’s answer: donors. At checkout, Zeffy shows a prominent tip prompt asking the donor to add a contribution to Zeffy itself. If enough donors tip, Zeffy says the org pays $0 in platform and processing fees. The default tip is pre-set and visible, which is exactly why it works and exactly why some donors notice.

Givebutter’s answer: donors too, but softer, with a fallback. Givebutter is also tip-supported, and if you turn tips off you instead pay a platform fee, tiered around 1%, 3%, or 5% depending on configuration, on top of the 2.9% + 30¢ processing. So Givebutter gives you a lever Zeffy does not really emphasize: kill the tip prompt and just pay the fee yourself.

What the tip prompt does to your donors

This is the part worth slowing down on, because it is the actual cost of "free." When a donor decides to give you $50, the tip prompt asks them to give more, to the platform, not to you. Most will. Some will feel a flicker of "wait, why am I tipping software?" And a few will quietly knock their gift down to compensate.

Zeffy’s prompt is more prominent, which is how it funds true $0 fees, and it can read as the donor subsidizing the platform. Givebutter’s is present but gentler. Neither is wrong. But you are making a choice on your donors’ behalf: you are trading your platform fee for a small, repeated ask on every single gift.

For a one-time event crowd, that is usually fine. For loyal monthly donors who see the prompt every month, it can wear. If keeping the giving experience clean and tip-free matters to you, that is a real reason to look at a flat-fee tool instead, more on that below.

Where the features split

If the tip model were the only difference, you would just pick the gentler prompt. But the products diverge.

Givebutter goes deep. Events with ticketing, peer-to-peer fundraising, team pages, auctions, and a surprisingly capable free CRM-lite. If your fundraising revolves around galas, runs, and supporters raising money on your behalf, Givebutter is genuinely strong, and the depth is the reason to choose it over Zeffy.

Zeffy goes broad. Donation forms, event tickets, memberships, e-tickets, raffles, a bit of everything, all at the same $0 promise. It is less polished and less deep on any single feature, but it covers a lot of ground for budget-first orgs that just need things to work without a bill.

So the question under the question is: do you need depth in events and P2P (Givebutter), or breadth across a lot of small needs at zero cost (Zeffy)?

Who should pick what

Run a lot of events, galas, or peer-to-peer campaigns and want one polished tool to handle them? Givebutter, and it is not close. The events and P2P depth is the whole reason it exists, and the tip prompt is mild enough to live with.

Need to cover a grab-bag of needs, forms, tickets, raffles, memberships, on a hard $0 budget, and your donors won’t mind a visible tip ask? Zeffy delivers true free across a wide surface. For budget-first small orgs, that is hard to argue with.

But if your concern is the donor experience itself, that every gift comes with a "tip the platform" nudge, that is the honest weakness of the tip model. A form that pays out to your own Stripe and asks donors at most to cover the actual processing cost, rather than to tip the platform an arbitrary amount, is a cleaner experience. That is the lane KindLumen sits in, and the org is charged nothing either way. The best donation platforms with no monthly fee piece weighs that tradeoff in more detail.

Frequently asked questions

Are Zeffy and Givebutter actually free?

Free to the organization, yes, if donors tip. Both fund the platform through optional donor tips added at checkout. Card processing still happens at roughly 2.9% + 30¢, which the tips are meant to cover. Givebutter also lets you turn tips off and pay a platform fee instead.

Which has a stronger tip prompt, Zeffy or Givebutter?

Zeffy’s tip prompt is more prominent, which is how it achieves true $0 fees for the org. Givebutter’s is present but gentler, and it offers a fallback platform fee if you disable tips entirely.

Is Givebutter or Zeffy better for events?

Givebutter is the stronger events platform, with deeper ticketing, peer-to-peer, team pages, and auctions. Zeffy covers events too but is broader and less deep. For an events-heavy org, Givebutter is usually the better pick.

Do tip-funded platforms cost my donors money?

Effectively, yes. The platform is funded by asking your donors to add a tip on top of their gift. Most donors tip, but it is a repeated ask on every donation, and some donors notice they are subsidizing software rather than your cause.
