The form builder that signs itself
tuyaform exists to make legally binding e-signatures free for everyone — not a paywalled add-on, but the whole point.
Why we built tuyaform
Most form builders treat signatures as a premium upsell, and most e-signature tools are expensive and clunky. We thought the basics — sending a document and getting it signed — should just be free.
So we built tuyaform: create a form or upload a document, send it to sign, and get back a legally binding, tamper-evident PDF with a full audit trail and Certificate of Completion.
Signing-first, not an afterthought
tuyaform is designed around signing from the ground up. Compliance with ESIGN, UETA, and eIDAS, a clear audit trail, and a verifiable certificate are built into every completed document — not bolted on.
Forms, surveys, and quizzes are here too, but the signature is the star.
Free, forever — funded by ads
We keep tuyaform free with unobtrusive advertising on our marketing pages. There are no subscriptions, no per-signature fees, and no surprise paywalls on the core signing flow.
Ads never appear on the private pages your recipients use to sign — that experience stays clean and focused.

No dark patterns, no selling your data, and no third-party ads on signing pages.
