Hey Product Hunt, Derick here, co-founder of Firma.dev. We built Firma.dev because every e-signature API we tried was either priced for enterprises or was an end-user app with an API bolted on as an afterthought. We wanted the opposite: an API-first product where signing is something you integrate in an afternoon, not a procurement cycle. 💸 Pricing. €0.029 per envelope, about 3¢, pay-as-you-go with no minimums or contracts. DocuSign can run $4-5 for a single envelope, so for most teams that's around 99% less. 🛠️ Who it's for. If your product touches contracts, you need this: HR and onboarding tools sending offer letters, property platforms handling leases, freelance marketplaces with client agreements, healthtech collecting consent forms, fintech onboarding flows, or any SaaS sending NDAs and proposals. At 3¢ per envelope you can make signing a built-in feature instead of a cost center. ⚡ Developer-first. Clean REST API, embeddable template and signing editors, and you can give each of your own customers an isolated workspace with separate templates and usage. 🤖 Built for AI-assisted development. We ship two MCP servers, one for our docs and one for the API itself with 84 tools, so coding agents generate accurate Firma.dev integration code and can even manage signing requests directly. We have a guide for Claude Code, plus Antigravity, Cursor, Lovable and the rest in our docs. 🌍 Legality. Designed to support the frameworks that matter, and e-signatures are legally recognized in 55+ countries. 🔑 Try it free. There's a sandbox key with real documents and unlimited usage, so you can test the whole flow before paying anything. No demos, no sales calls. We'd love your feedback, especially from anyone who's fought with e-signature integrations before. I'll be around all day to answer questions. Derick Happy Friday hunters. 😎
