About
Firma.dev is a developer-first e-signature API from a Barcelona team, built so SaaS products can add document signing without DocuSign-style seats or contracts.
Pricing is pay-as-you-go at €0.049 per envelope, with no monthly minimum. Isolated white-label workspaces, an embeddable template and signing editor, REST API plus MCP, and EU-only document storage (AWS Paris) are the product. Signatures are designed for eIDAS SES/AdES, GDPR, ESIGN, and UETA, with immutable audit trails and PAdES B-LTA.
Use it to embed signing in your own product, keep client workspaces separate, or send contracts without standing up an e-sign vendor for the team.
