The donation form is often the final step between a potential supporter and a completed gift. It's the moment of commitment, and if that experience feels clunky, slow, or confusing, donors drop off. The good news is that the right form builder can meaningfully improve donation completion rates, make recurring giving frictionless, and connect seamlessly with the CRMs and payment processors your organization already relies on.
Choosing the right tool means weighing several factors: ease of setup, nonprofit-specific features like recurring donations and fund designation, supported payment methods, pricing and nonprofit discounts, and how well the platform integrates with your existing tech stack. Whether you're a small grassroots organization or a large enterprise nonprofit, there's a solution built for your needs.

1. Orbit AI
Best for: Nonprofits prioritizing conversion optimization and intelligent donor experiences
Orbit AI is an AI-powered form builder that uses intelligent optimization and conditional logic to create conversion-focused donation forms tailored to how donors actually behave.
Where This Tool Shines
Orbit AI approaches donation forms differently from dedicated nonprofit platforms. Rather than layering fundraising features on top of a basic builder, it starts with conversion science. The AI engine adapts form behavior based on donor interactions, helping reduce the friction that causes abandonment before a gift is completed.
For nonprofits that want a modern, branded experience without compromising on intelligence, Orbit AI's conditional logic is particularly powerful. You can show entirely different fields and messaging to a first-time donor versus someone upgrading to a recurring gift, creating a personalized experience without requiring technical expertise to set up.
Key Features
AI-Powered Form Optimization: Adapts form behavior in real time based on how donors are interacting, reducing drop-off at critical moments.
Conditional Logic: Dynamically shows or hides fields based on donor choices, such as presenting different options for one-time versus recurring giving.
Mobile-Responsive Design: Modern, clean form designs that render beautifully on any device, reducing mobile abandonment.
CRM and Payment Integrations: Connects with popular CRMs and payment processors so donor data flows where you need it.
Donor Qualification Capabilities: Helps identify high-value supporters through intelligent form logic, so your team can prioritize follow-up effectively.
Best For
High-growth nonprofits and development teams that want to maximize donation form performance through smart design and AI-driven optimization. Particularly well-suited for organizations that already have a donor management system and need a best-in-class form layer on top of it.
Pricing
A 7-day free trial gets you started. Paid plans start at competitive rates. Visit orbitforms.ai for current pricing details.
2. Donorbox
Best for: Nonprofits wanting an all-in-one dedicated donation platform with built-in donor management
Donorbox is a dedicated nonprofit donation platform offering embeddable forms, recurring giving, peer-to-peer fundraising, and a built-in donor CRM.
Where This Tool Shines
Donorbox was built specifically for nonprofits, and it shows. The platform handles the full donation lifecycle from the first gift to recurring donor management and tax receipt generation, all within a single system. This tight integration means less time stitching together different tools.
The recurring donation engine is especially strong. Smart upsell prompts encourage one-time donors to upgrade to monthly giving at the right moment, which can significantly improve donor lifetime value over time.
Key Features
Embeddable Forms and Pop-Up Widgets: Easily embed donation forms anywhere on your site or trigger them as pop-ups for campaign-specific pushes.
Recurring Donation Management: Full recurring giving infrastructure with smart upsell prompts built directly into the checkout flow.
Peer-to-Peer and Crowdfunding: Launch supporter-driven fundraising campaigns alongside your standard donation forms.
Multiple Payment Methods: Accepts credit cards, ACH transfers, Apple Pay, Google Pay, and PayPal.
Built-in Donor CRM: Manage donor records, generate tax receipts, and track giving history without a separate system.
Best For
Small to mid-sized nonprofits that want a purpose-built platform handling donations, recurring giving, and basic donor management without needing to integrate multiple tools.
Pricing
Free plan available with a 1.5% platform fee. Pro plan starts at $139/month with reduced platform fees for higher-volume organizations.
3. Givebutter
Best for: Nonprofits looking for a modern, free-to-start platform with strong social and community fundraising features
Givebutter is a modern fundraising platform that combines donation forms, event ticketing, peer-to-peer campaigns, and social sharing tools with a generous free tier.
Where This Tool Shines
Givebutter's biggest differentiator on the free tier is its approach to fees. Rather than charging nonprofits a platform fee, it uses an optional donor tip model where supporters can choose to cover platform costs. This makes it genuinely free to use at the organizational level, which is a significant advantage for budget-conscious nonprofits.
The platform also excels at community-driven fundraising. Built-in social sharing, team fundraising, and peer-to-peer tools make it easy to mobilize supporters beyond just a donation button on your website.
Key Features
No Platform Fees on Free Tier: Optional donor tip model means nonprofits keep more of every dollar raised.
Customizable Donation Forms: Branded forms with flexible design options to match your organization's identity.
Event Ticketing and Peer-to-Peer: Run events, galas, and supporter-led campaigns all within the same platform.
Social Sharing Tools: Built-in sharing features and team fundraising pages to amplify reach organically.
Integrations: Connects with Salesforce, Mailchimp, and other commonly used nonprofit tools.
Best For
Nonprofits running community-driven or event-based fundraising campaigns who want a modern platform without upfront platform costs. Also a strong option for organizations with active volunteer fundraiser networks.
Pricing
Free plan with no platform fees (standard payment processing fees apply). Premium plans available for additional features and enhanced support.
4. Bloomerang
Best for: Nonprofits focused on improving donor retention and engagement through data-driven insights
Bloomerang is a donor management CRM with integrated online donation forms, built around the idea that retaining existing donors is as important as acquiring new ones.
Where This Tool Shines
Bloomerang's donation forms are not the star of the show here. The CRM is. The platform is designed to give development teams a deep view of donor engagement, retention risk, and giving history, with donation forms that feed directly into that data ecosystem. Every form submission enriches the donor profile automatically.
The donor retention scoring feature is particularly useful for prioritizing outreach. Instead of treating all donors equally, Bloomerang surfaces who is at risk of lapsing and who is most engaged, helping teams focus their stewardship efforts where they matter most.
Key Features
CRM-Integrated Donation Forms: Form submissions flow directly into donor records, eliminating manual data entry.
Donor Retention Scoring: Engagement tracking that identifies at-risk donors and highlights your most loyal supporters.
Recurring Giving and Pledge Management: Manage recurring donors and multi-installment pledges from within the CRM.
Automatic Tax Receipts: Acknowledgment emails and tax receipts generated automatically upon donation.
Wealth Screening: Built-in donor insights to help identify major gift prospects within your existing database.
Best For
Mid-sized nonprofits with established donor bases that want to prioritize retention and stewardship alongside acquisition. Best when the CRM, not just the form, is a core part of the workflow.
Pricing
Starts at approximately $125/month, with pricing that scales based on the number of donor records in your database.
5. Fundraise Up
Best for: Nonprofits wanting AI-driven donation optimization and a premium checkout experience
Fundraise Up is an AI-powered donation checkout platform that uses machine learning to personalize suggested gift amounts, optimize payment method presentation, and improve the overall giving experience.
Where This Tool Shines
Fundraise Up treats the donation checkout as a conversion optimization problem, much like e-commerce platforms approach cart completion. The AI engine analyzes visitor signals to suggest personalized ask amounts and surface the payment methods most likely to result in a completed gift for each individual donor.
The one-click recurring upsell feature is a standout capability. After a donor completes a one-time gift, they're presented with a seamless option to convert to a monthly donor without re-entering payment information. This kind of frictionless upgrade path can meaningfully improve recurring donor acquisition rates.
Key Features
AI-Optimized Ask Amounts: Personalized suggested donation amounts based on individual visitor signals and behavior.
One-Click Recurring Upsells: Post-donation prompts to convert one-time donors to recurring supporters without additional form steps.
10+ Payment Methods: Supports digital wallets, ACH, credit cards, and cryptocurrency alongside standard options.
Multi-Language and Multi-Currency: Suitable for international organizations or campaigns with global donor audiences.
A/B Testing and Analytics: Deep reporting and testing capabilities to continuously improve donation form performance.
Best For
Mid-to-large nonprofits with meaningful donation volume who want to invest in AI-driven checkout optimization and have the data to benefit from A/B testing and analytics.
Pricing
Percentage-based platform fee model. Contact Fundraise Up directly for current rates based on your organization's donation volume.
6. Jotform
Best for: Nonprofits wanting maximum flexibility with a general-purpose builder and a large template library
Jotform is a versatile drag-and-drop form builder with an extensive library of nonprofit donation form templates and support for a wide range of payment gateways.
Where This Tool Shines
Jotform's strength is flexibility. It's not a dedicated nonprofit platform, but its template library includes a wide variety of donation form designs that can be customized without any coding. If your organization has specific form requirements that more opinionated platforms don't accommodate, Jotform typically has a way to build it.
The payment gateway support is notably broad, covering PayPal, Stripe, Square, and many other processors. This is helpful for organizations that have existing payment relationships they want to maintain rather than switching to a platform-specific processor.
Key Features
Extensive Template Library: Hundreds of templates including nonprofit-specific donation forms ready to customize and deploy.
Drag-and-Drop Builder with Conditional Logic: Build complex, branching forms without technical knowledge.
Broad Payment Gateway Support: Accepts PayPal, Stripe, Square, and many additional processors.
Nonprofit Discount: 50% discount on paid plans for qualifying nonprofit organizations.
Multiple Sharing Options: Embed forms on your site, share as standalone pages, or distribute via QR code.
Best For
Nonprofits that need flexible, customizable forms and want to maintain their existing payment processor relationships. Also a strong fit for organizations with varied form needs beyond just donations.
Pricing
Free plan available (5 forms, 100 submissions per month). Paid plans start at $34/month, with a 50% nonprofit discount available for qualifying organizations.
7. GiveWP
Best for: Nonprofits running WordPress websites who want native donation functionality without leaving their CMS
GiveWP is a dedicated WordPress donation plugin that adds customizable donation forms, donor management, and recurring giving directly to any WordPress site.
Where This Tool Shines
For nonprofits already invested in WordPress, GiveWP eliminates the need to embed third-party forms or manage a separate fundraising platform. Everything lives inside WordPress, which means your team manages donations the same way they manage the rest of the website. The Gutenberg block support makes placing forms anywhere on any page genuinely straightforward.
The add-on ecosystem gives GiveWP significant extensibility. You can layer on Mailchimp sync, Salesforce integration, Zapier automation, and more, building exactly the stack your organization needs without paying for features you don't use.
Key Features
Native WordPress Plugin: Full Gutenberg block support for placing donation forms anywhere on your site.
Multiple Form Display Options: Multi-step forms, modal overlays, and embedded inline forms to suit different campaign contexts.
Recurring Donations and Fund Designation: Donors can choose giving frequency and direct gifts to specific funds or programs.
Donor Dashboard: Donors can log in to manage their giving history, update payment methods, and cancel recurring gifts.
Extensive Add-On Ecosystem: Integrations with Mailchimp, Salesforce, Zapier, and many other tools available as add-ons.
Best For
Nonprofits that run their website on WordPress and want donation functionality that feels native to their CMS rather than an embedded third-party widget.
Pricing
Core plugin is free. Premium plans start at $149/year for add-on bundles, with higher tiers available for larger feature sets.
8. Classy
Best for: Large nonprofits and enterprise organizations running complex, multi-channel fundraising programs
Classy is an enterprise fundraising platform offering donation forms, campaign pages, peer-to-peer fundraising, and event management built for large-scale nonprofit operations.
Where This Tool Shines
Classy is built for complexity. Large nonprofits running simultaneous campaigns across multiple channels, managing major donor programs, and handling enterprise-level compliance requirements will find that Classy is designed for exactly this operating environment. The platform's Salesforce integration is deep and well-maintained, which matters enormously for organizations where the CRM is central to operations.
The recurring giving program management, branded as Classy for Recurring, gives development teams granular control over recurring donor journeys, including failed payment recovery and upgrade prompts that are built into the platform rather than requiring custom development.
Key Features
Branded Campaign Pages: Fully branded fundraising pages with embedded donation forms for campaigns, events, and appeals.
Peer-to-Peer and Event Registration: Manage supporter-led fundraising and event ticketing within the same platform.
Classy for Recurring: Dedicated recurring giving program management with retention and recovery tools built in.
Salesforce Integration: Deep, native Salesforce integration with advanced reporting capabilities.
Enterprise Security and Compliance: PCI compliance and enterprise-grade security standards suitable for large organizations handling significant donation volume.
Best For
Large nonprofits and enterprise organizations with complex fundraising programs, significant donation volume, and a need for deep Salesforce integration and enterprise-level compliance.
Pricing
Custom pricing based on organization size and needs. Contact Classy directly for a quote tailored to your organization.
9. Zeffy
Best for: Nonprofits that want a completely free platform with zero fees on every donation
Zeffy is a 100% free fundraising platform for nonprofits, charging zero platform fees and zero transaction fees, funded entirely by optional donor contributions.
Where This Tool Shines
Zeffy's model is genuinely different from every other platform on this list. Rather than charging nonprofits a platform fee or taking a percentage of donations, Zeffy asks donors if they'd like to leave an optional tip to support the platform. Nonprofits receive 100% of every dollar donated. This is not a limited free tier with caps. It's the entire platform, free.
Beyond the pricing model, Zeffy covers the core fundraising bases well: donation forms, event ticketing, membership management, and peer-to-peer campaigns are all included. For resource-constrained nonprofits, the combination of zero fees and solid functionality is hard to argue with.
Key Features
Truly Zero Fees: No platform fees, no transaction fees for nonprofits. Donors receive a prompt to optionally tip Zeffy, but it is never mandatory.
Donation Forms, Events, and Memberships: Core fundraising tools all available within the free platform.
Peer-to-Peer Fundraising: Supporter-led campaign pages included at no additional cost.
Automatic Tax Receipts: Donor management and automated tax receipt generation built in.
Sustainable Funding Model: Platform is funded entirely by voluntary donor contributions, keeping it free for nonprofits long-term.
Best For
Small to mid-sized nonprofits, grassroots organizations, and any nonprofit where minimizing fees is the top priority. Also a strong option as a supplementary platform for specific campaigns alongside a primary CRM.
Pricing
100% free for nonprofits. No platform fees, no transaction fees, no hidden costs whatsoever.
Which Tool Is Right for Your Nonprofit?
The best donation form builder depends heavily on your organization's size, tech stack, budget, and fundraising goals. Here's a quick breakdown to help you orient your decision.
Best for conversion optimization: Orbit AI brings AI-powered form intelligence and conditional logic that no dedicated nonprofit platform matches for pure conversion performance. If donation form abandonment is your core challenge, this is where to start.
Best dedicated nonprofit platform: Donorbox covers the full donation lifecycle, from embeddable forms to recurring giving to donor CRM, in a single purpose-built system that's accessible for most organization sizes.
Best free options: Zeffy wins on pure cost, with genuinely zero fees for nonprofits. Givebutter is a strong alternative if you also need event ticketing and community fundraising features alongside the zero-platform-fee model.
Best for WordPress: GiveWP is the clear choice for organizations running their site on WordPress. Native integration with your CMS beats embedding third-party widgets every time.
Best for enterprise: Classy is built for large-scale operations with complex multi-channel programs, while Fundraise Up is the better fit for organizations focused on AI-driven checkout optimization at significant donation volume.
Best for donor retention: Bloomerang's CRM-first approach and retention scoring make it the right choice when stewarding your existing donor base is as important as acquiring new ones.
Best for customization: Jotform's broad template library, flexible builder, and wide payment gateway support make it the most adaptable option for organizations with specific or varied form requirements.
No single tool wins across every category. The right move is to match the platform's core strengths to your organization's most pressing challenge. If that challenge is getting more donors across the finish line on your donation form, conversion optimization should be your starting point.
