Company details

Written by the company

Firma.dev is an e-signature API built for developers at startups and mid-sized SaaS companies. It lets teams embed document signing directly into their product, without the enterprise overhead or bloated pricing of tools like DocuSign. Key things that define it: Pay-as-you-go pricing at €0.029 per envelope , making it significantly cheaper than any major competitor. Fast integration via a clean, well-documented API with embedded editors for both templates and signing. Hours to integrate, not weeks. No friction to start — no upfront costs, no monthly minimums, no sales calls required. Customer Workspaces for SaaS products that need isolated, per-customer environments with separate templates and usage tracking. On compliance, Firma.dev is designed to support ESIGN, UETA, HIPAA, FDA 21 CFR Part 11, eIDAS (SES and AdES), GDPR, SOC 2, and ISO/IEC 27001. The positioning is simple: if you're a developer who needs to ship e-signing into your product without signing a contract or paying per seat, Firma.dev is built for that.

Great service, best prices in the history of eSigning.

Great service! Works as advertised! Fractionally cheaper than all of the competitors. If you can program a bit, or in the modern age of LLM, there is no reason to be a prisoner to Docusign or Pandadoc or other similar predatory services when a perfectly capable and amazingly priced solution like Firma.dev exists.

I've already migrated one large company over and the numbers don't lie: Pandadoc was going to cost upwards of $14,000 for the next year of service. The same quantity of service from Firma.dev was estimated to cost ~$100.

Think about that for a second. The next best competitor was quoting us over $5000.

On the high end, we're saving nearly the entire $14,000. On the low end, we're still saving almost $5000. That is just over a single year, and this isn't even some massive conglomerate, just a company operating in a half a dozen states.

It doesn't make sense to pay exponentially more. Firma.dev is 50x cheaper than their nearest competitor, and 140x cheaper than the service we were already paying for.

Switch over, you wont regret it.

Great Support

The support from this company is great. I set up a new automation for signatures and had multiple questions about the API, and the support team was very responsive in getting back to me. Where functionality was lacking, they were agreeable to put it on their enhancement list. So far, I have a great experience working with this company.

Made our free tool actually viable

I run a free toolkit for independent musicians at BigBadBird, including a split sheet generator that needs e-signatures on every document. At $2-3 per envelope from DocuSign or HelloSign, the tool wouldn't have existed. Firma's pricing is the only reason I can offer this for free with no signup, no paywall, no per-user limits. Beyond price, the API is genuinely well-designed. I built the entire integration in one session. Create envelope, send, get users, receive webhooks, no OAuth dance, no mandatory frontend widget, no SDK weirdness. Webhooks come HMAC-signed which is table stakes for security but some bigger competitors still don't offer it. Per-signer signing links meant I could control distribution through own branded emails instead of being forced into Firma's email flow. If you're building something where free or low-cost e-signing is core to the product working at all, Firma is the obvious pick.
