Firma.dev is the #1 Product of the Day on Product Hunt

On Friday, June 12, Firma.dev was ranked the #1 app of the day on Product Hunt, across every product that launched. It was our second launch on the platform, and the response from developers told us we are building the right thing.

Firma.dev is the cheapest e-signature API on the market. At €0.029 per envelope, about 3¢, pay-as-you-go with no minimums or contracts, it runs around 99% cheaper than DocuSign, where a single envelope can cost up to $4 to $5 or more. You sign up, grab an API key, and start building the same day. No procurement cycle, no sales calls.

The product is API-first, not a signing app with an API bolted on later. It ships a clean REST API, embeddable template and signing editors, and Customer Workspaces that give each of your own customers an isolated space with seperate templates and usage. Firma.dev is also the only e-signature API that is fully white-label, so signing looks like a native part of your product rather than a third-party tool. For teams building with AI coding agents, we ship two MCP servers, one for our docs and one exposing 84 API tools.

This is exactly what won people over on launch day. Rasmus Rowbotham, founder of workflow automation startup FoundBase, integrated Firma.dev in a single evening. As he put it, "I'm a geek. I don't have to speak to anyone. I can just get started now." You can read the full FoundBase story to see how it came together.

Thanks to everyone who upvoted, commented, and tried the API. We are just getting started. Want to see how we stack up against the rest? Check our e-signature API comparison.
