Firma.dev Reviews & Product Details

Firma.dev is a pay-as-you-go e-signature API built for developers at startups and SaaS companies. At $0.029 per envelope with no monthly minimums, it costs a fraction of legacy platforms while delivering enterprise-grade signing capabilities. The API handles the complete e-signature workflow: document uploads, template creation, signer management, embedded signing experiences, audit trails, and webhooks. Developers can integrate Firma.dev in hours using SDKs for popular languages and comprehensive documentation. Embedded editors let you build template creation and signing flows directly into your product without redirecting users to third-party interfaces. For SaaS companies, Customer Workspaces provide private, partitioned environments for each of your customers. Templates, signers, and envelope usage stay isolated with no cross-customer data exposure. This makes Firma.dev ideal for platforms that need white-label document signing without the complexity of managing multiple accounts. Firma.dev is designed to support major e-signature legal frameworks including the U.S. ESIGN Act, UETA, and eIDAS (SES and AdES levels) in the EU. The platform helps organizations align with data protection requirements under GDPR and privacy frameworks like HIPAA. Infrastructure runs exclusively in the EU on SOC 2-certified cloud services, with security practices designed around ISO/IEC 27001 principles. Every envelope generates a tamper-evident audit trail with timestamps, IP addresses, and signer authentication records. Real-time webhooks and per-customer analytics give you visibility into signing activity across your entire platform. Getting started takes minutes. Sign up, grab your API key, and send your first envelope with 25 free production credits. No sales calls, no annual contracts, no credit card required.

"Quick Setup and Powerful API for eSignatures"

5/5

What do you like best about Firma.dev?

I really appreciated that Firma.dev is really easy to install. It only took me a few minutes before I was actually able to run my signatures, even though I'm not necessarily technical. Review collected by and hosted on G2.com.

What do you dislike about Firma.dev?

I think it's mostly an API tool. So anything when it comes to the UI, outside the API, is not on par with, like, other solutions, but it's not their angle and they're focused on the API. Review collected by and hosted on G2.com.

"Easy Setup, Fair Pricing, and Great API Access"

5/5

What do you like best about Firma.dev?

API access, fair prices, easy setup, and quick customer service. Review collected by and hosted on G2.com.

What do you dislike about Firma.dev?

Not very much. The interface is pretty basic, and it feels like some branding features are missing. Review collected by and hosted on G2.com.

What problems is Firma.dev solving and how is that benefiting you?

As a consulting and accounting firm, we send multiple signature requests to our clients throughout each engagement. Managing this workflow manually was not sustainable, so automation became essential for us.

Firma.dev has been a great solution because they provide a fully API-based signature request service that integrates seamlessly into our systems. The pricing is incredibly competitive, especially compared to other providers, and the value we receive is outstanding.

It has significantly improved our efficiency and client experience. Review collected by and hosted on G2.com.

I like Firma.dev because it's easy to integrate, which was important for us when we migrated from another e-signature software. The responsive customer service is great, as they quickly address any troubles or queries, saving us time. The pricing is a big plus for us as a startup; finding ways to lower costs is always a priority. The setup was simple, especially with the help of customer service.
