Form backend pricing that's actually fair.
splitforms pricing has 3 plans. The Free plan costs $0 forever and includes 500 form submissions per month, unlimited forms, owner email notifications, a submissions dashboard, and spam filtering — no credit card required. Pro is $5 per month for 5,000 submissions per month and adds CSV, XML, and PDF exports, signed webhooks, integrations like Slack and Google Sheets, custom auto-responder emails, and priority support. The 3-Year plan is a single $59 payment covering 15,000 submissions per month for 36 months. Every plan uses the same API endpoint with unlimited forms, and honeypot-flagged spam never counts toward the monthly quota. There are no overage fees, per-form charges, or setup costs, and paid plans can be cancelled anytime. AI agents can also create forms and read submissions through the free MCP server included on every plan.

Why we price form backend like this.
Three principles behind every dollar on this page.
Free should mean free
500 submissions/month and unlimited forms is enough to run a real portfolio site, a small SaaS landing page, or a startup's first contact flow indefinitely. Not a trial. Free, forever, no card.
Paid should be obviously fair
$5/month covers 5,000 submissions for growing sites with every paid feature unlocked — deliberately under the threshold where you'd second-guess the bill.
Honest beats clever
No overage surprises, no annual contracts hidden behind monthly numbers, and no paid feature maze. The price you see is what you pay.
How to upgrade and how to get help.
Plain answers to the two questions every new splitforms user asks on day one — “how do I move to a paid plan?” and “who do I email if something breaks?”
How to upgrade from Free
- Sign in to your dashboard and open the Billing tab.
- Choose Pro ($5/month) or the $59 3-Year plan and check out via Stripe — Apple Pay, Google Pay, card, or SEPA.
- The new quota applies instantly. Your access key, forms, webhooks, exports, and integrations unlock immediately on a paid plan.
How to get billing or technical help
- Email hello@splitforms.com — one business day on Free, under 4 hours on Pro and 3-Year.
- Read the docs for API reference, framework recipes, and migration guides.
- Check status.splitforms.com for real-time uptime and incidents.
- Refunds within 14 days (Free, Pro) or 30 days (3-Year) — no questions asked, just reply to your invoice email.
Pricing & plan FAQ.
Refunds, plan changes, what counts as a submission, file uploads, custom domains, team accounts, GDPR, technical limits, support, and whether unused submissions roll over — answered below.
Is splitforms really free? What's the catch?
There's no catch. The Free tier is 500 form submissions per month, unlimited forms, honeypot spam filtering, owner notification emails, and the submissions dashboard — forever, no credit card. Exports, webhooks, and integrations unlock on Pro at $5/month and above.
How does pricing compare with other form backends?
Free allowances now vary widely: SubmitKit and Static Forms also list 500 per month, while Netlify includes form submissions within its platform credit model. splitforms differentiates with source-visible infrastructure, agent-native setup, signed webhooks from $5/month, and an optional $59 3-Year plan. Always compare current pricing, hosting requirements, and file-upload terms for your stack.
Why a 3-year plan and not a true lifetime deal?
Lifetime deals are how indie SaaS dies. We picked 36 months because it's long enough to feel like a deal (cheaper than 12 months of Pro) but short enough that we can keep our promises. After 36 months you renew at whatever the rate is then, or move on. No surprises.
What happens if I exceed 500 submissions on the Free plan?
The API rejects new Free-plan submissions after the monthly quota is reached so you have a clear reason to upgrade. Pro is the $5/month paid step.
Are there any hidden fees, overage charges, or per-form fees?
No. Your tier price is what you pay — there are no overage charges, no email-volume fees, no webhook fees, and no 'enterprise add-on' upsells. Every plan — Free, Starter, Pro, and 3-Year — includes unlimited forms.
Can I cancel anytime? Is there a refund?
Yes. Cancel from your dashboard at any time — you keep access until the end of the billing period. We refund within 14 days, no questions asked. The 3-Year plan is also refundable in the first 30 days.
Do you offer discounts for students, non-profits, or open source?
Yes. Email hello@splitforms.com from your .edu address, your non-profit domain, or with a link to your public OSS project and we'll sort you out — usually a free Pro plan for as long as you're active.
Can I use one access key on multiple websites or client projects?
Yes. Every plan includes unlimited forms — Pro and 3-Year add the volume agencies need for lots of client forms.
What payment methods do you accept?
All major credit and debit cards (Visa, Mastercard, AmEx) via Stripe. Apple Pay and Google Pay at checkout. SEPA and ACH for annual prepay. Cryptocurrency for the 3-Year plan on request.
Do you charge sales tax or VAT?
Stripe handles regional tax compliance — VAT for EU, GST for AU/IN, sales tax for relevant US states. Your invoice shows the exact breakdown. Business buyers can add a VAT/EIN number at checkout for reverse charge.
What counts as a 'submission'? Do test or spam submissions count?
A submission is one successful POST to the splitforms API that passes validation and is stored in your dashboard. Honeypot-flagged spam never counts toward your quota. Validation failures (missing access key, blocked domain, malformed body) never count. Test submissions you send from your own dashboard's preview tool do count — they're indistinguishable from real submissions, which is exactly what makes them a genuine end-to-end verification.
Do unused submissions roll over to the next month?
No — quotas reset at the start of each calendar month, and unused submissions do not roll over. We keep the model simple on purpose: you always know exactly how many submissions are available this month, and you never have to track a balance.
Are file uploads supported, and do they count toward the quota?
File uploads work when the Storage integration is connected. The limit is 5 files per submission, 5 MB per file, with total storage space per plan: 25 MB on Starter, 500 MB on Pro, and 5 GB on Business and 3-Year. Each form submission with attached files counts as one submission, not one per file. If an account lapses to the free plan, stored files are kept for 30 days and then deleted.
Can I use my own custom domain for the form endpoint?
Not yet — custom domains (a CNAME like forms.yourdomain.com pointing at splitforms) are in development for Pro and 3-Year tiers. Today every plan posts to splitforms.com/api/submit. If custom domains matter for your setup, email hello@splitforms.com and we'll notify you the day it ships.
What if I need more than 15,000 submissions per month?
The Business plan covers high-volume sites and agencies: unlimited monthly submissions, unlimited forms, everything in Pro, and priority support. It's set up personally — email hello@splitforms.com with your expected volume and we'll get you running the same day, with invoiced billing available.
Are there team accounts, multiple seats, or shared inboxes?
Today an account is a single login with unlimited forms and an account-wide BCC list, which covers most agencies and small teams. True multi-seat team accounts with per-user roles and audit logs are on the roadmap and will be included on Pro and 3-Year at no extra cost when they ship.
Is splitforms GDPR-compliant? Do you offer a DPA?
Yes. Submissions live in Postgres with row-level security so only you can read your own data — splitforms never sells, shares, or trains models on form submissions. We sign a Data Processing Addendum (DPA) on request for any plan, free included. EU data residency is on the roadmap for the Pro and 3-Year tiers.
What are the technical limits — payload size, rate limits, fields per form?
Each submission stores up to 100 fields, with text values trimmed to 10,000 characters per field. Paid file uploads allow up to five files at 5 MB each. The submit endpoint currently allows 6 requests per minute and 20 per 15 minutes for each IP-and-access-key pair, returning HTTP 429 when either window is exceeded.
How do I upgrade from Free to Pro, or change plans later?
Upgrade from your dashboard at /dashboard/billing in two clicks — your access key stays the same, your forms keep working, and the new quota applies immediately. Pro is $5/month, and switching to the 3-Year plan starts a new 3-year billing cycle.
What kind of support do I get on each plan?
Free plan: email support at hello@splitforms.com with a one-business-day response, plus public docs and GitHub Discussions. Starter, Pro, and 3-Year are paid plans; Pro and 3-Year get priority support under 4 hours during business hours. Status, incidents, and historic uptime live at status.splitforms.com.
