Form builders have historically split into two camps: the design-first tools that fall apart the moment you need an API, and the developer tools that look like a tax return. We built SureForm on the belief that this trade-off is lazy. You should get both.
An API you'd actually use
Everything you can do in the dashboard has a counterpart in REST API v1, authenticated with per-workspace API keys. Forms, submissions, contacts — readable and writable by machines you control. Integrations are named and per-form: you define an endpoint once, then choose exactly which forms use it. No accidental global hooks, no mystery deliveries.
Delivery you can trust
A webhook that fires once and shrugs is not an integration — it's a hope. Ours run through a retrying delivery queue, so a transient failure on your end doesn't mean lost data. Outbound URLs are SSRF-guarded, and notification recipients are scoped strictly per form, so one form's alerts can never leak into another's.
Security as a default, not a plan
- Layered anti-spam: honeypots with a server-side fail-safe, plus ALTCHA and Turnstile challenges when you want them.
- Respondent verification by email or SMS for forms where identity matters.
- Answers encrypted at rest, per-IP rate limits, dedicated rate limits on AI routes, and two-factor authentication on accounts.
None of this appears in a screenshot. All of it appears the day something goes wrong — which is the only day that counts.
Embeds that behave in production
Embeds are ID-based, so renaming a form regenerates its pretty slug without breaking a single iframe already in the wild. The embed background is transparent by default, the loader is hardened, and your form drops into any page like it was born there.
Design is not the compromise
All of that engineering ships underneath forms that look like someone cared — 28 preset styles, full per-form styling, custom fonts and colors. The craft on the surface and the rigor underneath aren't competing priorities. They're the same priority, pointed at different layers.
"Developer-grade" doesn't mean it looks like a terminal. It means it behaves like infrastructure.
Build something beautiful. Wire it to something serious.
