Verdict: Most "free" crowdfunding platforms waive the platform fee on the pricing page and still pass 2.2 to 2.9% + $0.30 processing back to your nonprofit, which costs roughly $300 to $440 per $10,000 raised. Zeffy is the only platform in this set where $10K in equals $10K out.
What works: Zeffy covers all processing itself; Donorbox and Mightycause bring strong donor-CRM features for orgs willing to pay for them; CauseVox is a solid P2P surface for teams on its paid tiers.
What doesn't: "Donor-tip-funded" pricing on Fundrazr, Fundly, and CauseVox Starter is conditional on donor behavior, so your real cost is unpredictable. Pricing on Fundly and Fundrazr was hard to verify at write time. Subscription platforms like Mightycause's higher tiers can price out grassroots orgs before campaign one.
Best for: Grassroots nonprofits, PTAs, schools, sports teams, and small organizations running goal-based, time-bound campaigns where every fee dollar matters.
Worth considering if: You're a $1M+ enterprise nonprofit with dedicated fundraising staff. a heavier paid suite is the fit; the rest of this list is calibrated for sub-$1M campaigns, where paying a platform to crowdfund is a cost without a reason.

Why "free" crowdfunding platforms aren't actually free
Run the math on a $10,000 crowdfunding campaign. On a platform that waives its subscription but routes payments through Stripe or PayPal at 2.2 to 2.9% + $0.30 per donation, your nonprofit loses roughly $300 to $440 before the campaign clears. A $50,000 campaign loses $1,500 to $2,500. The fee on the pricing page is not the cost. The cost is what arrives in your bank account. Zeffy is the only platform in this list that is truly zero-fee: no platform fee and no processing fee passed to your nonprofit. See the fundraising platform with no fees guide for the full breakdown. If you are still in the campaign-design phase rather than the platform-selection phase, start with the crowdfunding for nonprofits definitive guide instead.
How to choose the right crowdfunding platform
Five criteria separate platforms that protect grassroots budgets from those that quietly tax them:
- True cost per $10K raised. Add platform fee + processing fee + monthly subscription. "$0 to start" with 2.2% + $0.30 processing equals roughly $300+ per $10K, not free.
- Free-tier honesty. Ask who absorbs Stripe or PayPal: the platform, the donor via optional tip, or you. Tip-funded models opt in under 50% in practice.
- Grassroots fit. Self-serve signup with no demo gate and no monthly minimum.
- Campaign-type coverage. One-time crowdfunding, peer-to-peer, and recurring conversion all included without paywalled upgrade tiers. A fundraising thermometer is table stakes too.
- Tax-receipt and donor-record handling. Automated IRS-compliant receipts and a donor record that survives the campaign end date.
1. Zeffy: the only truly zero-fee crowdfunding platform
Zeffy is the only platform in this set where a $10,000 campaign nets $10,000. There is no platform fee, no transaction fee, and no credit card fee passed to the nonprofit. Stripe processing exists; Zeffy absorbs it. 100K+ nonprofits run on Zeffy and have raised $2B+ to date.
That model is built for grassroots: PTAs, schools, sports teams, small nonprofits, and lean development shops running goal-based, time-bound campaigns where every fee dollar shrinks mission impact. Setup is self-serve with no demo, no contract, and no monthly minimum. See how Zeffy's zero-fee donation forms work before you commit.
Key crowdfunding features:
- Customizable donation pages with suggested amounts and one-time or recurring options
- Peer-to-peer campaigns for team and community fundraising, included free
- Fundraising thermometers, goal trackers, and real-time donor dashboards
- Automated IRS-compliant tax receipts and built-in donor CRM
- Ticketing, auctions, raffles, and membership tools in the same account
- Mobile-first donor experience that works on any device
True cost per $10K raised: $0. The full $10,000 lands in your bank account.
How Zeffy is free: No platform fee, no transaction fee, no credit card fee. Ever.
Case in point: The University of Ottawa Annual Campaign has run more than 30 campaigns on Zeffy, raises roughly $2.5 million annually, set a $4 million target for 2025, and has saved approximately $10,000 in fees by moving to a zero-fee model. Read the full University of Ottawa case study.
We switched to Zeffy after the company we were using raised their rates and added a monthly fee. Zeffy has been great! As a nonprofit, we receive 100% of the money donated to us. We are a small nonprofit, so we do not take advantage of many of the features Zeffy has to offer, but it is nice to know more is available as we continue to grow. I would definitely recommend Zeffy to other nonprofits.

2. GoFundMe
GoFundMe is the name most people picture when they hear "crowdfunding": the biggest, most-recognized platform, with built-in discovery that can carry a one-time, story-driven campaign further than a tool nobody has heard of.
The cost lives in two places. GoFundMe charges 2.9% + $0.30 on every donation (2.2% + $0.30 for verified 501(c)(3) charities) as a processing fee deducted from your cause, and it asks each donor for an optional tip on top of that. On $10,000 raised, that is roughly $290 (about $220 as a verified charity) before the tip ask. Zeffy charges no platform fee, no transaction fee, and no credit card fee, so the real contrast is "a fee plus a tip" versus "no fee."
Is it worth it for a small nonprofit? For a single viral campaign where reach beats margin, GoFundMe's brand can help. For recurring gifts, tickets, and everyday giving, the per-donation fee compounds, and GoFundMe is not built to manage donors, receipts, or repeat giving the way a nonprofit needs.
GoFundMe also sells GoFundMe Pro (formerly Classy), an enterprise fundraising suite for $1M+ organizations. That is a different product, not a crowdfunding tool.
Cons for grassroots nonprofits:
- A processing fee on every donation, plus a donor tip ask on top
- Built for viral one-off campaigns, not recurring or everyday giving
- Thin nonprofit tooling: limited donor management, receipting, and repeat-giving infrastructure
Side-by-side breakdown: GoFundMe alternative.
3. Donorbox
Donorbox is the same product surface as Zeffy on the feature side: donation forms, recurring giving, peer-to-peer, events, memberships. The difference is the fee stack. On the free Standard tier, Donorbox charges a 2.95% platform fee on top of Stripe's processing, which works out to roughly $545 stripped from every $10,000 raised before any Pro upgrades (source: donorbox.org/pricing). Pro at $150/month drops the platform fee and adds advanced customizations, analytics, and integrations; Premium adds priority support and custom domains.
Donorbox's Standard free tier does include unlimited donation forms, pages, campaigns, ticketing, QuickDonate, and reporting, so feature-light grassroots orgs can technically run on the free tier. The trade is the per-donation cut on every gift.
Cons for grassroots nonprofits:
- 2.95% platform fee on the free tier compounds with Stripe on every donation
- Pro features (custom domain, advanced analytics) require a $150/month subscription
- Events and memberships sit on a higher platform-fee tier
4. Mightycause
Mightycause is a CRM-first crowdfunding platform with peer-to-peer, giving-day, and donor-record tools bundled together. The platform lists a $0/month starting plan as of June 2026; confirm the current tier structure on mightycause.com before you commit, as pricing here has shifted over time.
For the Mightycause vs Zeffy comparison: on a single $10,000 crowdfunding campaign, Mightycause's free tier still routes processing through its payment provider, so the nonprofit absorbs the per-donation processing cost. Zeffy absorbs all processing itself, so the same $10,000 campaign nets $10,000.
Cons for grassroots nonprofits:
- Pricing structure has changed; confirm the current tier on mightycause.com before signup
- Donor experience flagged as confusing in user reviews
- Limited campaign-page customization compared to dedicated crowdfunding-first tools
Strengths: Donor CRM is the platform's strongest surface. If a built-in CRM is the deciding factor and a tiered subscription is acceptable, Mightycause is in the conversation.
5. CauseVox
CauseVox offers peer-to-peer fundraising as one feature among several core surfaces (donation forms, events, auctions, CRM). It's strong on P2P specifically, but it isn't a P2P-only specialist. The Starter tier runs on donor tipping with processing pass-through to the nonprofit; the paid Essential, Power, and Advanced tiers add P2P, branded campaign pages, and other features behind a monthly subscription. Confirm the current paid-tier amounts on causevox.com before quoting.
Cons for grassroots nonprofits:
- Branded campaign pages and P2P sit behind paid tiers, not on Starter
- Starter's "free" framing depends on donor tipping, which typically opts in under 50%
- Processing pass-through means the nonprofit absorbs Stripe on every gift
If P2P is your anchor use case but you don't want a subscription, you can run peer-to-peer on Zeffy free with no tier upgrade required.
6. RallyUp
RallyUp is a flexible crowdfunding platform that supports a broad range of campaign formats: sweepstakes, auctions, raffles, events, and traditional donation campaigns. That format variety makes it appealing to nonprofits that want to run mission-driven experiences beyond a standard donation page.
RallyUp's fee structure includes a platform fee on top of payment-processing costs; confirm the current rates on rallyup.com before launching a campaign, as the fee schedule was updated in 2026. The platform does offer a nonprofit discount tier, so orgs should verify eligibility directly on rallyup.com/pricing.
Key features:
- Sweepstakes, raffles, auctions, events, and crowdfunding all available in one account
- Embeddable campaign widgets for existing nonprofit websites
- Peer-to-peer and team fundraising supported on eligible tiers
- Branded campaign pages with customizable visuals
Cons for grassroots nonprofits:
- Platform fee applies on top of processing, so the nonprofit does not receive 100% of donations
- Fee schedule requires direct verification on rallyup.com; published rates have shifted
- Format variety adds setup complexity for orgs that need a simple donation page fast
True cost per $10K raised: Verify on rallyup.com before launching. Processing fees pass to the nonprofit in addition to the platform fee, so the true cost depends on your campaign type and tier.
7. Fundrazr
Fundrazr supports several crowdfunding models (subscriptions, peer-to-peer, microprojects) with a donor-tip-funded fee structure. At write time, Fundrazr's fee details required direct verification on fundrazr.com, so confirm the current fee structure before launching a campaign on the platform.
Cons for grassroots nonprofits:
- Tip-funded platform-fee model means your real cost depends on donor opt-in behavior, not a published rate
- Custom reporting flagged as limited in user feedback
- Processing fees pass to the nonprofit regardless of tipping
8. Fundly
Fundly is a crowdfunding site that supports nonprofits, individuals, schools, and other organizations, with strong social-share integration. At write time, Fundly's pricing page did not surface clear fee details, so confirm the platform is operating and verify current pricing on fundly.com before committing a campaign to it.
Cons for grassroots nonprofits:
- Payment processing has been reported to take up to seven days, which is a risk on a deadline-driven campaign
- Pricing transparency was limited at write time
- Documented operational reliability concerns in user reviews
Looking for Zeffy alternatives? Here's the honest answer
If you landed here searching "Zeffy alternatives" or "Zeffy competitors," the honest framing is this: every other platform in this guide charges your nonprofit something on every $10,000 raised, either as a platform fee, a processing pass-through, a monthly subscription, or a combination. Zeffy is the only one in the set that doesn't.
And Zeffy isn't just the cheapest place to crowdfund, it's built to do the job: unlimited donation forms and peer-to-peer pages, donor management, and automatic receipts, all free. For the discovery that draws people to crowdfunding in the first place, Zeffy runs a free nonprofit directory at zeffy.com/home/donate where donors browse and give to verified causes, 100% fee-free. The trade most "alternatives" ask you to make, paying for reach or features, isn't one you have to make here.
Which platform is right for your nonprofit?
Map your org to the platform built for your shape:
- PTAs, schools, sports teams, small nonprofits, grassroots campaigns under $1M: Zeffy. Truly zero-fee, self-serve, every campaign type included, with a free nonprofit directory for donor discovery.
- Running recurring gifts, events, and everyday giving alongside a campaign: Zeffy. The per-donation fees on other platforms compound fastest here, and Zeffy keeps all of it free.
- $1M+ enterprise with dedicated fundraising staff and a procurement process: the heavier paid suites are built for that workflow. For everyone else, paying a platform to crowdfund is a cost without a reason.

FAQs - Crowdfunding Platforms for Nonprofits
Can nonprofits use crowdfunding?
Yes. Crowdfunding works well for giving days, emergency response, advocacy campaigns, capital-project pushes, and time-bound community fundraisers. The benefits for grassroots orgs are community-building (donors see social proof of others giving), marketing reach across social and email, and speed (you can run a goal-based campaign in days, not months).
What is the best crowdfunding platform for nonprofits?
The best platform is the one where the most of every donation reaches your mission. Zeffy is the only platform in this guide where $10,000 raised equals $10,000 received: no platform fee, no transaction fee, no credit card fee. For $1M+ enterprise nonprofits with dedicated fundraising staff and a procurement process, a heavier paid suite is the better-calibrated fit.
Is there a truly free crowdfunding platform for nonprofits?
Yes, but read the pricing page carefully. Many platforms advertise "free" while still routing 2.2 to 2.9% + $0.30 processing back to your nonprofit via Stripe or PayPal, which costs roughly $300 to $440 per $10,000 raised. Zeffy covers all processing itself, so the nonprofit's true cost is $0.
How is Zeffy free?
Zeffy charges nonprofits nothing: no subscription, no platform cut, and no processing fee passed through. The platform covers all processing costs itself, so 100% of every donation reaches your mission.
How do I set up a crowdfunding page?
Set your goal and timeline, choose your platform, design the page with your story and visuals, configure the donation flow (suggested amounts, recurring option, tax-receipt automation), then promote across email, social, and your website. For step-by-step setup on Zeffy, see the crowdfunding for nonprofits definitive guide.
Mightycause vs Zeffy: which is cheaper per $10K raised?
Zeffy nets the full $10,000. Mightycause routes processing through its payment provider, so the nonprofit absorbs the per-donation cost on top of whatever subscription tier applies; confirm the current tier structure on mightycause.com before committing.
