What website is this?
Firma.dev is an e-signature API built for developers, letting SaaS apps send documents, collect multi-party signatures, and archive completed files inside an embedded flow. Billing is per envelope with no monthly contract, plus white-label UI and isolated customer teams—a better fit for teams wiring signing into product code, not for someone who only needs to sign a file by hand once in a while.
Key Features
- Call a REST API to create templates, send documents, and check signing progress.
- Embed signing UI in your product via iframe or prebuilt components.
- Receive view, sign, and completion events through webhooks and Server-Sent Events.
- Create isolated teams per SaaS customer with white-label branding and permissions.
- Produce audit trails and completion certificates aligned with ESIGN, eIDAS, and related frameworks.
- Use a test-mode API key to run real documents through the full flow before you pay.
Use Cases
- A SaaS team embeds contract signing in loan, lease, or compliance workflows so users never leave the console for an external signing site.
- A legal-tech product spins up an isolated team per law firm to build templates, set signing order, and download signed PDFs in-app.
- A fintech app triggers API envelopes at onboarding or disbursement, using webhooks to update business state and archive certificates.
- A white-label provider embeds signing in a client portal and resells the capability under its own brand, billed by envelope volume.
Who is it for?
- SaaS developers who need in-app e-signatures without extra accounts or page redirects.
- Small engineering teams that prefer API integration and pay-as-you-go over per-seat monthly fees.
- B2B platform operators who need multi-tenant isolation, white-label UX, and webhook automation.
- Not a good fit: individuals or admins who only occasionally sign PDFs by hand and do not need an API.
- Not a good fit: large legal procurement chains already deep in an enterprise signing ecosystem where migration cost outweighs per-envelope savings.
How It Compares to Similar Tools?
Many e-signature products sell seats and enterprise plans, and integration often means OAuth redirects or fixed monthly fees. Firma.dev is API-first: full access on signup, per-envelope billing, and embedding in hours is the stated goal. If signing must live inside your product kernel with per-customer data isolation and your own UI brand, this path is usually shorter; if procurement depends on mature enterprise template libraries, legal training, and large pre-sales support, seat-based platforms may still fit better. It covers send–sign–archive and does not replace PDF editors or contract drafting tools.
FAQs
Q: Does Firma.dev require a long-term contract or monthly subscription?
A: No. The vendor describes pay-as-you-go per envelope with no monthly minimum or long-term contract; see the official pricing page for details.
Q: Are Firma.dev e-signatures legally enforceable?
A: Yes, in principle. The service aligns with ESIGN, UETA, eIDAS, and GDPR and provides audit trails and completion certificates; applicability still depends on document type and jurisdiction.
Q: Do I have to build my own signing UI to integrate Firma.dev?
A: No. Besides the REST API, it offers iframe, embedded form builder, and multi-framework examples; you can also use only the API and webhooks with a custom UI.
Q: Is Firma.dev suitable for occasional personal signing?
A: Not really. It targets developers embedding signing at scale in applications; one-off manual signing is often simpler with a general-purpose tool.
