What it is
Backend endpoint for HTML forms on static sites — point the form action at a Formspree URL and submissions arrive by email and in a dashboard. Adds spam filtering (honeypot, reCAPTCHA, Akismet), file uploads, autoresponders, webhooks and integrations with Slack, Google Sheets and Linear.
Why it earns a slot
Lets a plain HTML page or a static Next.js export accept contact forms with zero server code. The React package gives you
useForm with validation and submission state built in.Know before you commit
50 free submissions vanish fast once bots find your endpoint — enable spam filtering on day one. Notification emails come from Formspree's domain, so they can land in spam until you allowlist them.
