Firma.dev

Firma.dev offers a secure, really affordable e-signature API, you know, for developers. It's built for SaaS companies to just embed document signing straight into their apps. They boast a price of only €0.029 per envelope, no contracts to sign, and no minimums, which feels pretty unique in the market. The whole idea is giving users turnkey e-signature features without those annoying redirects or extra accounts to manage. It's all about keeping folks on your platform.

Integration is quick and painless, often takes just minutes, just a few lines of code. It uses a simple REST API so any programming language works, which is neat. A big draw is the fully white-labeled aspect; you brand it as your own. This means your users never even see Firma.dev, which is smart. They emphasize strong compliance too, covering ESIGN, UETA, eIDAS, and GDPR, with audit trails and completion certificates a standard.

For SaaS builders, there's a powerful complete REST API. You can manage unlimited teams, white-label everything, and scale pretty easily. Things like real-time event streams for document status and team activity are there. You can create unlimited, isolated teams for your SaaS customers too, with their own branding and webhook settings. Templates are simple to create, letting users define fields right inside your app.

They even provide embeddable UI components, like a template editor and a signing experience. This means less work for developers, which is what we all want. The system also includes webhooks for real-time notifications, so you get updates on signing events, perfect for updating your app's state. It runs on AWS, with all customer data stored securely in the EU, encrypted at rest and in transit. SOC 2 and ISO 27001 are on their roadmap, which is good to hear. Support is direct from engineers, not sales, which is a big plus for dev teams.

Firma.dev hits a sweet spot, providing an e-signature API that's genuinely cheap for developers. Integration speed is impressive, with most teams getting setup in a few hours. The white-labeling is a huge plus, meaning your customers won't see other branding during signing, which good for user experience. We really think this tool is a solid choice for SaaS companies looking to add document signing without breaking the bank or dealing with complicated enterprise solutions.
