Firma.dev - E-signatures API for your app averaging ~3¢ per envelope

by•
At €0.029 per envelope (about 3¢), Firma.dev runs about 99% cheaper than DocuSign, where one envelope can cost $4-5. Pay-as-you-go, no minimums, no contracts. Built developer-first for startups and SaaS teams who'd rather integrate signing in an afternoon than sit through a sales cycle: clean REST API, embeddable template and signing editors, integration in hours. Test everything free with a sandbox key, real docs and unlimited usage, before you pay a cent. Get an API key and start building.

The pricing is what made me stop and look. Most esignature APIs seem affordable until you start scaling usage.

 Yah thanks Büşra .. dont get me started on what real volume means to Docusign etc. Its crazy. Even then, they don't come down to our prices. Thanks for taking a look. 😁

Does it support advanced stuff like multiple signers with order, reminders, and webhooks for status changes?

 Hi Thami. Yes, our API is very powerful, and one of the largest on the market. We have everything you asked about: multiple signers with order, reminders (from us or you), custom domains, graphics, etc per workspace, and tons of (and those are even per workspace). Thanks for taking a look!

3 cents per envelope with no minimums is honestly the pricing model e-signatures should have had years ago. Indie hackers and small SaaS teams have been stuck either paying DocuSign enterprise rates or duct-taping PDFs together. Really excited to try this out.

 Thanks!! We're excited to have you let us know if you need anything We have a lot of spam tickets to work through from the launch but we're generally very responsive.

The pricing caught my attention first but the sandbox plus no minimums part is probably even more valuable for smaller teams

 Yup! And you can get started super easy .. versus talking to a sales team and getting quotes for API usage. Thanks for looking! 😁

The API-first angle makes a lot of sense here. E-signatures are usually treated like a standalone tool, but for many products the real need is embedding signing cleanly into an existing workflow without making users leave the app.
