What the free plan includes
- Unlimited documents and pages, with no monthly cap.
- Drawn, typed or uploaded signatures, initials, dates and text fields.
- A completion certificate page and a SHA-256 tamper seal on every file.
- The verifier, for you and for anyone you send the file to.
- Offline use after your first visit.
Your pages are not watermarked. The only free-plan branding is one line on the certificate page, which links to the verifier.
Why it can be free
Signing runs on your device, so there are no per-document server costs to pass on. The site itself is static files, which are cheap to serve.
What Pro adds, and what it costs
Pro is optional. It adds your own logo and details on the certificate in place of OpenSigner branding, field templates you can export and import, batch signing with a zip download, a per-file audit-trail PDF and a two-signer preset. It is a one-time payment that does not renew automatically: ₹3,999 a year or ₹499 for 30 days in India, and $49 a year or $6 for 30 days elsewhere. The Pro page shows the price for your region before you pay, and purchases are covered by a 7-day refund policy.
No account at all
There is no sign-up step even for Pro: the licence key is stored in your browser. Free users never create anything.
