About
Firma.dev is the developer-first e-signature API built for startups and mid-sized SaaS companies. With a clean REST API and embeddable template and signing editors, developers can ship e-signature workflows in hours, not weeks.
Firma.dev's pricing model is straightforward: pay-as-you-go at just €0.049 (about 5 cents USD) per envelope. No monthly minimums, no contracts, no suprise fees. That's a fraction of the cost of legacy providers like DocuSign, which makes Firma.dev a strong fit for cost-sensitive teams scaling e-signature across products or customers.
Every customer gets a dedicated workspace, a secure, partitioned space for templates, documents, and envelope usage. This makes it easy to manage usage by client or environment, with no cross-tenant exposure and no complex access rules.
Firma.dev is designed with compliance in mind and aligns with key frameworks including the ESIGN Act, UETA, HIPAA, GDPR, and eIDAS. Security practices align with SOC 2 and ISO 27001 standard
