Free forever · 1 form · 100 delivered/mo · AI spam protection · No credit card

No CAPTCHA ever

Visitors never solve a puzzle or click a checkbox. A silent background check blocks bots before they can submit.

Spam actually blocked

Not "filtered later." Not "moved to a spam folder." Blocked before it ever reaches you — and it never counts toward your quota. You only pay for what's delivered.

Nothing stored — ever

Submissions are forwarded to your email or webhook and immediately discarded. No database of messages, no breach risk, no GDPR headaches.

Works with anything

Any HTML form, any framework, any site. One form for a portfolio or thousands via API — it just works.

Prefer to let your agent handle it?

If you build sites in Cursor, Claude, Codex, or similar tools, you can create a Boosterpack Forms endpoint from chat. Sign in once in the browser, then ask the agent for a contact form.

You only pay for what's delivered. Unlike other form services that charge per submission — including spam — we only count messages that pass our AI spam filter and actually reach you. Spam is blocked before delivery and never touches your quota.

Privacy by design

Built for compliance from day one.

Most form services store every submission in their database — making you the data controller of a growing pile of personal data you never asked for. Boosterpack Forms doesn't store submissions at all. Messages are forwarded and immediately discarded.

That means no data breach notifications for form data, no subject access requests to handle, and no third-party database full of your visitors' messages. Your form data stays where you control it — your inbox or webhook.

Even your destination email addresses are never stored in plain text — they're encrypted at rest with AES-256-GCM. A database breach reveals nothing useful.

GDPR-friendly

No submission data stored by us — no DPA needed for form payloads.

No breach risk

Submissions exist only in transit. Even email addresses are encrypted — a DB breach reveals nothing.

You stay in control

Data lands in your inbox or webhook — under your jurisdiction, your retention rules.
