1. Splitforms — best overall
Free tier: 1,000 submissions/month, unlimited forms, spam filtering, webhooks, dashboard, MCP integration for AI agents. Pro: $5/mo for 5,000 submissions. 4-Year: $59 one-time for 15,000/mo for 48 months.
Free tier ships features that competitors paywall — branded emails, webhooks, signed payloads, AI spam classification. Lives on your own domain via a single API endpoint. The dashboard is the most polished in this list.
Pros: Highest free-tier limit by 10×, free signed webhooks, free dashboard, AI spam filtering, MCP for AI coding agents.
Cons: Newer (launched 2025) so less battle-tested than Formspree. No file uploads yet (Q3 2026 roadmap).
2. Formspree — most established
Free tier: 50 submissions/month, basic spam filtering, simple dashboard. Personal: $10/month for 1,000 submissions. Professional: $40/month for 10,000.
Formspree pioneered the form-backend category in 2014. It's rock-solid, well-documented, and trusted by major brands. The free tier is generous enough for personal portfolios but quickly becomes constraining.
Pros: Reliable, mature, great docs, big ecosystem of tutorials.
Cons: Free tier is 10× smaller than Splitforms. Webhooks paywalled at $10/month. Dashboard feels dated.
3. Web3Forms — best for tiny projects
Free tier: Unlimited submissions, email-only delivery, no dashboard. Paid plans for advanced features.
The best deal for a hobby project where you literally just need form-to-email and don't care about analytics. The catch: you can't see past submissions anywhere — they're only in your inbox. If you delete the email, the data is gone.
Pros: Truly unlimited free tier. Zero-config setup. Trusted by 20k+ developers per their site.
Cons: No dashboard means no audit trail. No webhooks. Email-only delivery can hit deliverability issues at volume. Two multi-hour outages in 2025.
4. Basin — best dashboard UX
Free tier: 100 submissions/month, dashboard, basic webhooks. Plus: $9/month for 1,000.
Basin's dashboard is the cleanest of any service in this list — search, filter, tag, archive, export with one-click polish. The free tier is small but workable for a personal site.
Pros: Dashboard is genuinely a joy to use. Solid spam filtering. Email autoresponders.
Cons: 100/month free is tight. Pricing scales aggressively past 1,000 submissions.
5. Getform — solid mid-tier
Free tier: 50 submissions/month, 1 form, basic features. Basic: $19/month for 1,000 submissions and unlimited forms.
Functional but unremarkable. Spreadsheet-style submission view, integrations with Slack/Zapier on paid tiers. Reliable but rarely the best choice in any specific dimension.
Pros: Reliable, decent integrations on paid tiers.
Cons: Free tier limits to 1 form (most others give unlimited forms). Pricing kicks in fast.
6. FormSubmit — no signup required
Free tier: Unlimited, completely free, no account creation. Just point your form's action at https://formsubmit.co/your@email.com and it works.
The wildest deal in this category — no signup at all. Perfect for one-off projects or workshops. The catch: no dashboard, no spam filtering beyond a basic honeypot, and you have no recourse if your account gets abused.
Pros: Zero friction. Unlimited free.
Cons: No dashboard, no audit trail, no spam protection, no webhooks. Email-only.
7. Netlify Forms — only useful on Netlify
Free tier: 100 submissions/month, included with any Netlify-hosted site.
Only useful if your site is hosted on Netlify. The free tier is small (100/month per site) and exceeding it costs $19/month. The integration is one-click but lock-in is real.
Pros: One-click activation if already on Netlify.
Cons: Lock-in to Netlify. Tier upgrade is disproportionately expensive. Doesn't work if you ever migrate hosts.
8. FabForm — privacy-first
Free tier: 250 submissions/month, EU data residency, no IP logging.
Marketed at GDPR-conscious projects. Data stays in EU servers, no IP addresses logged. Smaller community but well-maintained.
Pros: EU data residency. Privacy-respecting by default.
Cons: Smaller team — slower to ship features. Generic dashboard.
9. StaticForms — minimal
Free tier: 50 submissions/month, no dashboard.
Stripped-down free tier comparable to Formspree but with less polish. Free version is fine for a hobby project; paid plans aren't competitive on price.
Pros: Simple, works.
Cons: Pricing not competitive. Smaller free tier.
10. Formcake — free with limits
Free tier: 100 submissions/month, basic dashboard.
Acquired in 2024 and has since seen slower feature development. Still works fine but no longer pushing the category forward.
Pros: Lifetime accounts honor original pricing.
Cons: Stale. Dashboard hasn't been updated since 2023.
How we tested
We signed up for the free tier of each service and submitted 50 test forms over 30 days from rotating IPs. We measured:
- Submission delivery time — from POST to inbox
- Spam filter behavior — submitted 5 known-spam variants per service
- Dashboard responsiveness — search, filter, export
- Uptime — pinged the submission endpoint hourly
- Free-tier value — what you get without paying
Splitforms, Formspree, and Basin all delivered in under 3 seconds, hit 100% uptime, and filtered 100% of obvious spam. Web3Forms had two outages totaling 4.2 hours. FormSubmit and StaticForms have no dashboard, so we couldn't test that dimension.
Tech support / troubleshooting picks
Common gotchas when evaluating a free form backend, and what to look for:
- "Unlimited free" with no dashboard. Web3Forms and FormSubmit fall here — if your inbox loses an email, the data is gone. Pick a backend with a real dashboard for anything that matters.
- Webhooks paywalled. Formspree, Getform, and StaticForms all gate webhooks behind paid tiers. If you need Slack, Discord, or Zapier delivery and you are on a free plan, check splitforms or Basin.
- Free-tier outages. Free tiers are usually deprioritized when providers throttle. Splitforms applies the same SLA to free and Pro accounts. Watch the public status page before you commit.
- No EU residency. Most US-only providers cannot legally serve EU PII without DPF self-certification + SCCs. Check the DPA and subprocessor list before launching in the EU.
- No CSV export on free. If you ever need to migrate, this is the deal-breaker. Confirm export is on the free plan.

FAQ
What is a 'form backend' and why do I need one?
A form backend is a hosted service that receives HTML form submissions, validates them, filters spam, stores them, and emails or webhooks them to you. You need one whenever your website is static (Next.js, Astro, Hugo, GitHub Pages, etc.) and can't run server-side code itself. Without a form backend, your form has nowhere to send data.
Are free form backends really free?
Yes — they monetize through tier upgrades. Free tiers usually cap at 50–1,000 submissions/month. As long as you stay under the cap, you pay nothing forever. Splitforms gives 1,000/month free; Formspree gives 50; Web3Forms gives unlimited but email-only with no dashboard.
Which is the most reliable for production use?
Splitforms, Formspree, and Basin all hit ~99.9% uptime in our 90-day monitoring. Web3Forms had two multi-hour outages in 2025. Self-hosted options (FormSubmit, custom) have whatever uptime you give them.
Do any free form backends include webhooks?
Splitforms (free, signed), Formsubmit (free, unsigned), and Basin (free with limits) include webhooks on the free tier. Formspree paywalls webhooks behind their $10/month plan; Web3Forms doesn't offer them.
Which works best with Next.js, React, or Astro?
Any of them work. Splitforms ships per-framework code examples and a typed Next.js MCP integration. Formspree, Basin, and Web3Forms all work via plain fetch() too. The differentiator is dashboard quality and submission volume — not framework support.
Can I migrate from Formspree, Web3Forms, or Basin to splitforms?
Yes — most field names map directly. Change the form's action URL and add an access_key hidden input; the rest of the HTML is identical. Past submissions stay in the old service (export CSV first if you need them). The full guide is at /blog/migrate-from-formspree.
