Firma.dev

I love the idea of making e signatures cheap enough that team stop treating them as a premium feature. One founder might see signing as a revenue stream, while another sees it as infrastructure. Your approach clearly leans toward the second philosophy.

The dedicated workspace model seems underrated. Many teams building multi tenant SaaS products spend a lot of time figuring out document separation and permissions. Was this designed from customer feedback or from your own experience?

Really interesting work! How did you handle documentation?

The pricing caught my attention first but the sandbox plus no minimums part is probably even more valuable for smaller teams

Does it support advanced stuff like multiple signers with order, reminders, and webhooks for status changes?

The pricing is what made me stop and look. Most esignature APIs seem affordable until you start scaling usage.

Is this API-only? We use PandaDoc, but not through the API—we use it as regular users to manually sign documents with clients and partners. Do you have a B2C/self-service option as well? If so, how much does it cost?

Great to see this live! Which use case are you seeing the most demand for?

Lunch & PH launch. 2 in the afternoon here in Barcelona lets see if we can keep going through evening US time 😅

The pricing is compelling, but pricing alone rarely wins enterprise deals. What feature or capability do customers cite most often when choosing Firma.dev over DocuSign besides cost?

Wow, the 84-tool MCP server is the interesting part. Pricing an e-sign API at 3¢ basically makes it cheap enough for an agent to fire envelopes on its own, which is great right up until an agent fires one it shouldnt. Whats the guardrail there, can you scope what an agent is allowed to send per workspace? Overall, well done!

The pricing is the obvious hook, but the sandbox key is what would make me try it. E-signature APIs always feel painful until you actually test the full flow. Curious how you handle audit trails and signer verification?

We're also launching today, but I couldn't help but leave this comment - kudos for the really good, appealing video! It's warm, has no fancy polish (which is a good thing I mean), and explains the benefits in an easily digesteable way :) we've done several launches, some of them with videos, and I always pay attention to what videos product makers do. This one is among great examples! PS: Sending the link to our finance guy! ;)

Congrats on the launch! The API-first approach and pay-as-you-go pricing make a lot of sense for modern SaaS products.

Hey Product Hunt, Derick here, co-founder of Firma.dev.We built Firma.dev because every e-signature API we tried was either priced for enterprises or was an end-user app with an API bolted on as an afterthought. We wanted the opposite: an API-first product where signing is something you integrate in an afternoon, not a procurement cycle.💸 Pricing. €0.029 per envelope, about 3¢, pay-as-you-go with no minimums or contracts. DocuSign can run $4-5 for a single envelope, so for most teams that's around 99% less.🛠️ Who it's for. If your product touches contracts, you need this: HR and onboarding tools sending offer letters, property platforms handling leases, freelance marketplaces with client agreements, healthtech collecting consent forms, fintech onboarding flows, or any SaaS sending NDAs and proposals. At 3¢ per envelope you can make signing a built-in feature instead of a cost center.⚡ Developer-first. Clean REST API, embeddable template and signing editors, and you can give each of your own customers an isolated workspace with separate templates and usage.🤖 Built for AI-assisted development. We ship two MCP servers, one for our docs and one for the API itself with 84 tools, so coding agents generate accurate Firma.dev integration code and can even manage signing requests directly. We have a guide for Claude Code, plus Antigravity, Cursor, Lovable and the rest in our docs.🌍 Legality. Designed to support the frameworks that matter, and e-signatures are legally recognized in 55+ countries.🔑 Try it free. There's a sandbox key with real documents and unlimited usage, so you can test the whole flow before paying anything. No demos, no sales calls.We'd love your feedback, especially from anyone who's fought with e-signature integrations before. I'll be around all day to answer questions.DerickHappy Friday hunters. 😎
