Features

A complete form backend that works for one site today and many sites tomorrow.

Collect from anywhere

HTML, JSON & multipart

Accepts plain form posts, fetch/JSON, and file uploads. No JavaScript required.

Per-form CORS

Lock a form to specific origins, or leave it open. Preflight handled automatically.

Submit behaviours

Redirect, return JSON, or show a hosted thank-you page — your choice per form.

File uploads

Attach files to submissions with per-file and total-size limits. Download them securely later.

Keep spam out

Honeypot

A hidden field that silently drops bots without annoying real people.

Rate limiting

Per-form, per-IP limits stop floods before they reach your inbox.

Turnstile & reCAPTCHA

One switch adds privacy-friendly captcha verification.

Custom rules

Block or flag on keywords and email addresses you define.

Notify & respond

Owner notifications

Email the right people instantly, with Reply-To set to the sender.

Auto-responder

Send a templated reply back to whoever submitted the form.

White-label sending

Verify a client's domain and send from their brand, not ours.

Link-only mode

For sensitive data, email a link to the dashboard instead of the contents.

Route & integrate

Signed webhooks

Delivered with HMAC signatures and automatic retries.

Slack

Post each submission to a channel via an incoming webhook.

Zapier & more

Consume the generic webhook from any automation tool.

CSV / JSON export

Download a form's whole submission history any time.

Solo or multi-site

Your own site

One workspace is enough for a portfolio, SaaS landing page, or side project — no client setup required.

Multiple sites

Add a workspace per site or client project — each with its own forms, inbox, and branding.

One dashboard

Switch between sites without separate accounts or logins.

Client inbox access

Invite a client to view their submissions read-only — optional when you need it.

Usage & billing

Plan limits, metering, and Stripe checkout built in.

Trust & compliance

Hosted in the US

Based in Toronto, Ontario, Canada. All submissions stored on US infrastructure — disclosed in our DPA and customer privacy snippet.

Auto-delete retention

Configurable per site with separate spam TTL. Daily purge job — no manual inbox cleanup like Formspree.

DPA + SCCs on all plans

Click-accept DPA at signup; Standard Contractual Clauses annex for EU/UK controllers.

Link-only email mode

Owner notifications can omit field values for privacy-sensitive forms.

DSAR erase

Delete a person's submissions on request in one action.

Access audit log

Every view, download, and delete is recorded.
