Best alternatives to Firma.dev in 2026
Think of Firma.dev as a signature stamp you can bolt onto any website or app: instead of building your own way to let people sign documents, or paying a lot of money for a big-name tool like DocuSign, a developer plugs in this API and gets a working "sign here" flow in hours, not weeks, at a fraction of the per-document cost. Firma.dev is a REST API for embedding legally-compliant electronic signatures (ESIGN, UETA, eIDAS, GDPR, HIPAA-compliant) directly into SaaS products, at €0.049 per envelope with no minimums or contracts. It ships with an OpenAPI-documented REST API, an embeddable template editor and signing widget, webhooks, white-label branding, multi-tenant workspaces for isolating customer data, and a 7-language signing interface supporting Latin, Cyrillic, Greek, Japanese and Korean scripts. Launched July 2026, it's EU-hosted (AWS Paris + Stockholm CDN) and closed-source.
