Free Form Backends Compared: What the Free Tiers Really Include
Six form backends with free tiers, compared on what actually matters: monthly limits, spam protection, retention, and whether 'free' means production or just testing.

Every form backend advertises a free tier, and the word "free" is doing wildly different jobs across them: sometimes it means run your production contact form forever, sometimes 50 submissions to evaluate us, and sometimes free because there's no dashboard, archive, or spam pipeline at all. This comparison sorts them by what the free tier actually is — with figures checked against the vendors' public pricing pages in September 2026.
Full disclosure: ShipMyForm is ours. Same rules as our full ten-service comparison: specifics over adjectives, and we say who beats us where.
The free tiers, side by side
| Service | Free allowance | Built for | The catch |
|---|---|---|---|
| ShipMyForm | 100/mo, recurring | Production forms | Newest product on the list |
| FormSubmit | Unlimited | Email forwarding | No inbox, archive, or real spam defense |
| Forminit (ex-Getform) | 100/mo + file uploads | Small production forms | Paid jumps straight to $19/mo |
| Formspark | 250 total, one-time | Trialing the service | Not recurring — it's a trial bundle |
| Formspree | 50/mo | "Testing and development" (their words) | 30-day archive, no redirect, no uploads |
| Netlify Forms | 100/mo per site | Netlify-hosted sites | Platform lock-in; steep per-site paid jump |
What separates "free for production" from "free trial"
Four questions expose the difference faster than any feature grid:
1. Is the allowance recurring? Formspark's 250 submissions are generous but one-time — a trial with honest framing. Monthly-recurring allowances (ShipMyForm, Forminit, Formspree, Netlify) are the ones that can run a real form indefinitely.
2. Does blocked spam eat your quota? The nastiest small print in the category. If it does, a bot wave can consume your month and silence your form — the attack wins twice. ShipMyForm and Basin explicitly don't count blocked spam; for anything else you're considering, ask before trusting it.
3. What spam defense is actually on the free tier? A lone honeypot is 2015's answer to 2026's bots. Layered server-side screening — rate limits, ML classification, review of ambiguous messages — is what keeps a public form usable, and it's rarely free elsewhere.
4. Where do submissions live, and for how long? FormSubmit keeps nothing (miss the email, lose the lead). Formspree's free archive is 30 days. ShipMyForm's free retention is six months with CSV export. The archive is what saves you the first time a notification lands in your own spam folder.
Honest picks by situation
- A hobby page where lost messages are acceptable → FormSubmit. Genuinely free, zero setup, and fine until the first email that mattered goes missing.
- A portfolio or small production site → ShipMyForm (100/mo with the full spam pipeline, inbox, webhooks, exports) or Forminit if free-tier file uploads are the deciding feature.
- Evaluating before a paid commitment → Formspark's 250-submission bundle or Formspree's 50/month are both explicit about being exactly that.
- Already on Netlify, minimal needs → Netlify Forms is zero-setup; just know what the lock-in costs when you move hosts.
Free tiers are repriced and repackaged constantly — one service on this list renamed itself entirely this year. Figures above were read from public pricing pages in September 2026; treat the vendor's site as authoritative, and see the Formspree pricing deep-dive for that service's full tier breakdown.
The bottom line
A free tier is a promise about whose problem your form is. ShipMyForm's promise, as of 2026: 100 submissions a month, every layer of spam defense, your data exportable, forever free — point a form at it and judge in the time it takes to paste a URL. And because switching backends is a one-line change, no choice on this page is expensive to unmake.
Frequently asked questions
- What is the best free form backend?
- Depends on what free must include. For a production contact form with spam filtering and an inbox, ShipMyForm's free plan (100 submissions/month, full spam defense, webhook delivery, CSV export) is built for exactly that. For bare email forwarding with no dashboard, FormSubmit is free and unlimited. Formspree's 50/month free tier is positioned by Formspree itself as for testing and development.
- Is there a completely free form to email service?
- Yes — FormSubmit forwards submissions to your email free without an account, and it's genuinely fine for hobby pages. The trade-offs are no stored archive, minimal spam filtering, and nothing to check when a notification email goes missing. Most sites outgrow forwarding the first time a real lead disappears.
- Do free form backends include spam protection?
- Unevenly — this is the biggest gap between free tiers. Some include only a honeypot, some gate real filtering behind paid plans. ShipMyForm includes its full pipeline (honeypot, rate limiting, ML classification, LLM review of ambiguous messages) on the free plan, and blocked spam doesn't count toward the monthly limit.
- What happens when I exceed a free tier's limit?
- Typically submissions stop being delivered until the month rolls over or you upgrade — which is why a spam wave eating your quota is dangerous on services where blocked spam still counts. Check both the number and the counting rules before trusting a free tier with a production form.
- Can I switch form backends later without rework?
- Usually yes. Most services use the same pattern (a URL in your form's action) and many honor the same reserved fields (_redirect, _subject, honeypot), so migrating is typically a one-line change. That low switching cost is exactly why it's safe to start on whichever free tier fits today.
