Firma.dev
Affordable developer-first e-signature API for SaaS applications.
What it does
• Integrates white-labeled document signing workflows into SaaS platforms via a clean REST API. • Manages siloed, partitioned customer workspaces to ensure secure, isolated data environments. • Embeds custom template creation and document signing editors directly into web applications. • Generates tamper-evident audit trails with timestamps, IP logging, and compliance certificates.
Why it works
Pay-as-you-go pricing model eliminates expensive monthly minimums and restrictive long-term contracts. Developer-first SDKs and drop-in UI components drastically reduce implementation time. Strict tenant data isolation protects multi-customer SaaS environments securely. Full regulatory compliance with ESIGN, UETA, GDPR, and eIDAS frameworks ensures legal validity.
