Contact forms
that become a lead inbox.

Spam-filtered submissions, email alerts, HMAC-signed webhooks and Slack — for any site, with no backend to run.

Built for the hostile web

Everything a form endpoint needs, and nothing it doesn't.

Spam dies before it costs you

Honeypot, atomic rate limits, your own Turnstile keys and heuristics all run before quota is touched. A bot flood never spends a submission you paid for.

A real lead inbox

Status, search, tags and notes. New → Contacted → Won. Not another email forwarder.

Webhooks at $7

HMAC-signed, retried, logged — at the tier where competitors still charge $24.
