Self-hostable

Everything you need to collect structured data

A modern form engine that scales from a single feedback widget to thousands of public submissions per day.

Dynamic form engine

14 field types, conditional logic, multi-section layouts. Build complex forms visually with a live preview.

Secure file uploads

Direct-to-S3 presigned uploads or local fallback. Magic-byte validation, MIME checks, and per-file size caps.

Spam-proof submissions

ALTCHA proof-of-work replaces hostile CAPTCHAs. Honest responders pay a tiny hash cost; bots are priced out.

Embed anywhere

Share a clean URL, drop an iframe, or wire up a button widget. Brand it to match your site.

Multi-tenant by design

Workspaces isolate projects, forms, submissions, and files. Perfect for agencies and multi-product teams.

Localized

Path-prefix i18n keeps URLs clean. Ship English and Chinese out of the box; add locales in one file.

From schema to embed in three steps

A clean pipeline — design, collect, ship.

01
Design
Compose fields visually with conditional logic, file uploads, and live preview.
02

Drop-in embed

One line of HTML is all it takes. The renderer handles state, validation, uploads, and verification.

<iframe
  src="https://your-host/en-US/f/acme/contact"
  width="100%"
  height="640"
  frameborder="0"
></iframe>
