Formspree Alternative

Formspree is the service that made "point your form at a URL" a normal thing to do, and its free plan still handles email notifications with spam filtering included. What sends developers looking is the gate above it: webhooks, Zapier and most third-party integrations sit on the paid plans, which start at $10/mo.

• •Formspree's free plan covers email notifications, with Formshield spam filtering on every tier including free.
• •Webhooks, Zapier and CRM/newsletter integrations require a paid Formspree plan, from $10/mo.
• •Formboost's free plan is 500 submissions/month across 10 forms, with Slack, Discord and Telegram included; custom webhooks start at $9/mo.
• •Formspree has file uploads and a documented REST API and CLI. Formboost has neither.

Formspree's plans page is the current source for the numbers, and the free tier is more capable than most free tiers in this category: Formshield spam filtering runs on every plan, free included, alongside optional reCAPTCHA. File uploads are available across all plans too.

The gating is on the automation side. Webhooks, Zapier, and the wider set of integrations — CRMs, newsletter tools, support desks — are on paid plans. So a form that emails you works on free indefinitely; a form that posts to Slack or creates a HubSpot contact does not.

Formspree also documents a REST API and a CLI, which matters below.

The paid tiers are within a dollar of each other, so price is not really the argument. The argument is what the free plan does: three chat destinations and 500 submissions across 10 forms, versus email delivery with spam filtering already handled.

Worth stating directly, because a comparison page that only lists wins isn't useful for deciding anything.

File uploads. Formspree includes them on all plans. Formboost has none — they're on the roadmap and not shipped. A form that accepts a file needs Formspree today.

A REST API and CLI. Formspree documents both. Formboost's only public API is the submission endpoint, POST /f/{alias}, which receives form posts and does not read them back. There's no account API, no CLI, no SDK and no MCP server. If your workflow involves pulling submissions into your own system programmatically, Formspree does that and Formboost does not.

An earlier version of this post claimed Formboost offered a free REST API and that Formspree had none. Both statements were wrong, in opposite directions.

• •500 submissions a month across 10 forms, no card, no expiry.
• •Email, Slack, Discord and Telegram delivery, all at the free tier.
• •Spam screening on every submission — heuristics on free, with an AI model reading the ambiguous ones from Starter and every submission from Pro. Each one carries a score and a readable reason.
• •JSON or form-encoded posts. Submitting with fetch is not a paid feature:

const res = await fetch("https://formboost.app/f/YOUR_ALIAS", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ email, message }),
});
// 202 Accepted

Or as an ordinary HTML form, which answers with a 302 to whatever you set in _redirect:

<form action="https://formboost.app/f/YOUR_ALIAS" method="POST">
  <input type="email" name="email" required />
  <textarea name="message"></textarea>
  <button type="submit">Send</button>
</form>

Both services take an ordinary form post, so the switch is usually the action attribute and nothing else. Field names carry through as column names, so markup, styling and client-side validation are unaffected.

Two steps worth planning:

• •Export your Formspree submissions before closing the account. Formboost doesn't import them.
• •Overlap rather than cut over. Point a duplicate form at the new endpoint, confirm submissions and notifications arrive as expected, then switch the live one.

The detailed walkthrough is in the migration guide, and the endpoint reference is in the docs.

• •Does the form accept files? Formboost's file uploads are still on the roadmap, so a form that needs an attachment today should keep a link-to-file field until they ship.
• •Do you pull submissions into your own code? Formboost has no read API; the dashboard, CSV export and a webhook on Starter are how submissions leave it.
• •Does a submission need to reach Slack, Discord or Telegram? That is free on Formboost, and the most common reason teams move.
• •Several forms across side projects? Formboost's free plan covers 10 forms and 500 submissions a month, renewed monthly.
• •A form that only emails you runs on the free plan, with heuristic spam screening on every submission.

Pricing on both sides moves. These figures were checked in August 2026 against Formspree's plans and Formboost's pricing.
