Description
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.

Could you build this?
Partial A signature pad UI and document upload API can be built rapidly, but a legally compliant, secure e-signature platform requires cryptographic audit trails, PKI digital certificates, and strict regulatory compliance (eIDAS, ESIGN).
What it would actually take: The architecture involves PDF rendering and modification engines (e.g., PDFKit, MuPDF), combined with X.509 PKI certificate generation, timestamp authority (TSA) integration, and cryptographic sealing (PAdES standards). It needs immutable audit logs, tamper-evident hash chaining, secure cloud key management (KMS/HSM), and compliance with eIDAS, ESIGN, and UETA legal requirements. Legal, cryptographic, and document-security expertise are mandatory.

Same idea, different domain
Nobody's really built a vertical saas tool for Insurance yet.
