For nonprofits and charitable organizations, your donation form is often the final step between a supporter's intent and their actual contribution. A clunky, slow, or untrustworthy-looking form can kill conversions at the worst possible moment—sometimes losing donations that supporters genuinely wanted to make.
The right donation form builder removes friction, builds trust, and makes giving feel effortless. Whether someone is donating $10 or $10,000, the experience should be smooth, secure, and mobile-friendly. We've evaluated the leading donation form builders based on ease of use, payment processing options, customization flexibility, and features that actually move the needle on conversion rates.
Here are the top donation form builders for organizations ready to maximize their fundraising potential in 2026.
1. Orbit AI
Best for: High-growth nonprofits focused on conversion optimization and intelligent donor engagement
Orbit AI brings AI-powered optimization to donation forms, adapting to donor behavior in real-time to maximize conversions.
Where This Tool Shines
Orbit AI stands out by applying conversion optimization technology typically reserved for commercial lead generation to the nonprofit space. The platform learns from donor interactions and adjusts form elements to reduce abandonment rates.
The modern, visually appealing designs help build trust immediately—crucial when asking for financial contributions. Forms look professional on any device, with intelligent field ordering that adapts based on how donors interact with the page.

2. Donorbox
Best for: Nonprofits prioritizing recurring giving and flexible form embedding options
Donorbox is a popular donation platform known for its versatile form options and strong recurring donation management.
Where This Tool Shines
Donorbox excels at giving nonprofits multiple ways to collect donations. You can embed forms directly on your website, use pop-up forms that appear at strategic moments, or create standalone donation pages. This flexibility means you can meet donors wherever they are in their journey.
The recurring donation features are particularly robust. Donors can easily manage their own recurring gifts, update payment methods, and adjust contribution amounts without requiring staff intervention—reducing administrative burden while improving donor experience.
Key Features
Multiple Form Types: Choose from pop-up, embedded, or standalone forms depending on your website strategy.
Recurring Donation Management: Donors can self-manage subscriptions, update payment details, and modify gift amounts through a donor portal.
Payment Method Variety: Accept credit cards, ACH transfers, PayPal, and other payment methods to reduce donation friction.

3. Givebutter
Best for: Budget-conscious nonprofits wanting social fundraising features without platform fees
Givebutter offers a free fundraising platform with social sharing capabilities and an optional donor-covered tip model.
Where This Tool Shines
Givebutter's zero platform fee model makes it attractive for smaller nonprofits and grassroots organizations. Instead of charging the organization, donors can optionally add a tip to cover Givebutter's costs—meaning 100% of the intended donation reaches your cause.
The social fundraising features turn supporters into fundraisers. Donors can create personal fundraising pages, share them across social media, and rally their networks around your cause. This peer-to-peer approach often reaches audiences your organization couldn't access directly.
Key Features
Zero Platform Fees: No monthly subscription or percentage taken from donations when donors cover the optional tip.
Social Fundraising: Supporters can create personal fundraising pages and leverage their networks on your behalf.
Event Tools: Sell tickets, manage registrations, and run auctions all within the same platform.
Team Fundraising: Create team-based campaigns for walks, runs, or other fundraising events.

Small to mid-sized nonprofits with limited budgets that want to maximize every dollar. Particularly effective for organizations that can mobilize supporters to fundraise on their behalf.
Pricing
Free for nonprofits. Donors can optionally add a tip to support Givebutter. Standard payment processing fees (around 2.9% + $0.30) apply.
4. Bloomerang
Best for: Donor retention-focused organizations wanting integrated CRM and donation forms
Bloomerang combines donor management with integrated donation forms, emphasizing retention and relationship building.
Where This Tool Shines
Bloomerang approaches fundraising from a retention-first perspective. The platform doesn't just collect donations—it tracks donor engagement over time and provides retention scoring to help you identify supporters at risk of lapsing.
The tight integration between donation forms and the CRM means every contribution automatically updates donor records, triggers appropriate communications, and informs your retention strategy. You're not just raising money; you're building relationships that lead to sustained giving.

Retention Analytics: Track donor engagement scores and identify supporters who may need re-engagement efforts.

5. Classy
Best for: Large nonprofits running complex, multi-channel fundraising campaigns
Classy is an enterprise fundraising platform built for organizations managing sophisticated campaigns across multiple channels.
Where This Tool Shines
Classy handles complexity that would overwhelm simpler platforms. If you're running simultaneous peer-to-peer campaigns, event fundraisers, recurring giving programs, and major donor initiatives, Classy provides the infrastructure to manage everything from one dashboard.

6. Fundraise Up
Best for: Conversion-obsessed organizations wanting AI-powered checkout optimization
Fundraise Up uses artificial intelligence to optimize donation checkout flows and increase average gift sizes.
Where This Tool Shines
Fundraise Up treats every donation form like an e-commerce checkout that needs constant optimization. The AI analyzes donor behavior in real-time, suggesting optimal gift amounts and using smart upsells to increase contribution sizes without feeling pushy.
The platform's focus on conversion rate optimization shows in details like one-click digital wallet support, streamlined checkout flows, and A/B testing capabilities. If you're leaving money on the table due to form abandonment or suboptimal gift amounts, Fundraise Up addresses those leaks directly.

Best for: WordPress-based organizations wanting native donation form integration
GiveWP is a WordPress plugin that adds donation form functionality directly to your existing website.

If your organization already runs on WordPress, GiveWP integrates donation forms without requiring third-party platforms or redirecting donors away from your site. Everything lives within your WordPress installation, giving you complete control over the donor experience.
The extensive add-on ecosystem lets you customize exactly what features you need. Want recurring donations? There's an add-on. Need detailed reporting? There's an add-on. This modular approach means you're not paying for features you won't use.

The all-in-one approach means you're not juggling separate tools for donation forms, donor management, and email marketing. Everything integrates seamlessly because it's built as a unified system rather than connected third-party tools.

Making the Right Choice
The best donation form builder depends on your organization's size, technical resources, and fundraising priorities. For conversion-obsessed teams wanting AI-powered optimization that adapts to donor behavior, Orbit AI delivers modern forms designed specifically for high-growth organizations focused on maximizing every opportunity.
Budget-conscious nonprofits will appreciate Zeffy's truly free model or Givebutter's tip-based approach—both eliminate platform fees that eat into donations. WordPress-based organizations should seriously consider GiveWP for native integration that keeps donors on your site throughout the giving process.
Established nonprofits focused on donor retention should explore Bloomerang's CRM-integrated forms that treat fundraising as relationship building rather than just transaction processing. Enterprise organizations running complex campaigns across multiple channels may need Classy's comprehensive suite and enterprise integrations.
Whatever you choose, prioritize three non-negotiables: mobile responsiveness, multiple payment options, and a checkout experience that builds trust. Your donors want to give—don't let your form get in the way.
Think about where donors abandon your current forms. Is it the payment step? The amount selection? The number of required fields? The right platform addresses your specific friction points rather than adding features you don't need.
