Why Compare Firma.dev and Docusign?

Docusign will not let you send a real document until a person at Docusign approves you. That is not a criticism of their API, which is large, well documented and genuinely capable. It is a description of their published Go-Live process, and it is the single biggest difference between the two products for anyone with a deadline.

The approval wall

Docusign's own developer documentation sets out the Go-Live process. Before an integration key can be promoted from the demo environment to production, it must complete 20 consecutive successful API calls, and then pass a review. Docusign puts the review itself at roughly a week.

So the sequence is: build against the sandbox, generate 20 clean calls in a row, submit, wait, and then start negotiating a price, because Docusign does not publish API plan pricing. Its developer plans page states that plans are priced on API features and envelope volume, and then shows no figures.

With Firma.dev you sign up, copy your API key, and send. There is no review, no sandbox-to-production promotion, and no sales conversation between you and a working integration.

I found Firma, and I think within two days of just messing around with the API, I was able to set up everything and have the communication between Firma to our LOS very, very quickly.

The same job, in code

Firma.dev

Creating and sending a document with Firma.dev is one authenticated call.

const response = await firma.signingRequests.createAndSendSigningRequest({
    "name": "Employment Contract - John Doe",
    "document": "JVBERi0xLjQKJeLjz9MK..."
});

That returns a 201 with the request already in sent status. Authentication is your API key in the Authorization header.

Docusign

The equivalent on Docusign requires an OAuth JWT flow with a one-time consent grant, a call to discover your account's base URI, and then an envelope definition that carries the document, the recipients, each recipient's ID, and the tab positions for every field:

// 1. JWT auth, plus a one-time consent grant
const token = await apiClient.requestJWTUserToken(
  integrationKey, userId, scopes, privateKey, 3600
);
// 2. Discover the account base URI
const userInfo = await apiClient.getUserInfo(token.accessToken);
// 3. Build the envelope
const envelope = {
  emailSubject: "Please sign",
  documents: [{ documentBase64: pdf, name: "Contract", fileExtension: "pdf", documentId: "1" }],
  recipients: { signers: [{
    email: "john.doe@example.com", name: "John Doe", recipientId: "1",
    tabs: { signHereTabs: [{ anchorString: "/sig1/", anchorUnits: "pixels" }] }
  }]},
  status: "sent"
};
await envelopesApi.createEnvelope(accountId, { envelopeDefinition: envelope });
// 1. JWT auth, plus a one-time consent grant
const token = await apiClient.requestJWTUserToken(
  integrationKey, userId, scopes, privateKey, 3600
);
// 2. Discover the account base URI
const userInfo = await apiClient.getUserInfo(token.accessToken);
// 3. Build the envelope
const envelope = {
  emailSubject: "Please sign",
  documents: [{ documentBase64: pdf, name: "Contract", fileExtension: "pdf", documentId: "1" }],
  recipients: { signers: [{
    email: "john.doe@example.com", name: "John Doe", recipientId: "1",
    tabs: { signHereTabs: [{ anchorString: "/sig1/", anchorUnits: "pixels" }] }
  }]},
  status: "sent"
};
await envelopesApi.createEnvelope(accountId, { envelopeDefinition: envelope });

Same Inbox, Different Amount of Work

Both end with a document in someone's inbox. One of them needed three fields.

The other half of the difference is our Docs MCP server. Point Claude, ChatGPT, Cursor or GitHub Copilot at it, and the assistant reads our full API reference and writes the integration itself.

Docusign did release an official MCP server in 2026, and it is worth knowing about. A free developer account connects to it with no form and no approval. But it is a set of four tools in open beta for calling its own APIs and triggering workflows, not a documentation server that builds your integration, and it does not remove the Go-Live requirement, because that approval sits on your integration key rather than on the MCP.

What this costs over a year

At 10,000 envelopes a year, Firma.dev costs €490. That is the whole bill. No seats, no minimum, no platform fee. The same volume on Docusign, at the €5 per envelope we use as a conservative working figure, is €50,000.

Docusign does not publish its API rates, so that number is an estimate rather than a quote, and reports of $15 and above per envelope are common enough that €50,000 may be the optimistic reading.

Either way the ratio is about 102 to one.

The idea that PandaDoc or DocuSign or whatever these providers charge for API access, it's an incredible [high] price point for a company like us to pay.

A seperate workspace for each of your customers

Workspaces let your application create an isolated environment for each of your own customers or business units, provisioned through the API. Each one has its own:

  • API key, its own templates and documents

  • Its own envelope usage

  • Its own branding and sending domain

  • Its own webhook secret. Nothing is shared between them.

Per-Workspace Isolation: True Multi-Tenancy for Embedded Signing

This is not the same as embedded signing, which only places a signing screen inside your app. Docusign offers embedded signing. What we could not find is per-workspace isolation with independent keys.

Creating one is a single call to POST /workspaces, and keys rotate per workspace, so revoking one customer's access never touches another's.

For a SaaS product that is genuine tenant isolation, provisioned by your code as customers sign up. For an agency it means every client seperated cleanly, each seeing your branding and your sending domain, with usage tracked per client so it can be billed on.

One API, Everything Included, at €0.049 per Envelope

What we will claim is that the endpoints you actually need to send a document are one coherent API rather than five products stitched together, and that embedded signing, the embeddable editors, the workspaces and EU hosting are included at €0.049 per envelope rather than waiting behind a tier and a review.

FAQ

Frequently asked questions

For any unanswered questions, reach out to our support team via email. We'll respond as soon as possible to assist you.

What makes Firma.dev different from other e-signature providers?

Three things. Price: €0.049 (~5¢) per envelope, against roughly €5 for Docusign, which does not publish its API rates. Access: you get an API key on signup and can send a real document straight away, with no Go-Live review. Isolation: each of your own customers can get a separate workspace with its own API key, which we could not find at Docusign.

How easy is it to integrate Firma.dev into my app?

Creating and sending a document is one authenticated call. MoXi, migrating from Docusign, had Firma.dev talking to their loan origination system in two days, and Ralio set theirs up with Claude Code in under five minutes. Our Docs MCP server lets Claude, ChatGPT, Cursor or GitHub Copilot read the API reference and write the integration for you.

Is Firma.dev secure and compliant?

Documents are encrypted in transit and at rest, and hosted in the EU as standard on AWS in Paris with CloudFront in Stockholm. Docusign limits EU data residency to its Enterprise tier. Firma.dev is compliant with the ESIGN Act, UETA, eIDAS (SES and AES) and UK eIDAS, and aligns with GDPR and HIPAA requirements. We do not offer qualified electronic signatures today.

Do I need to sign a contract or commit to a monthly plan?

No. You pay per envelope, with no monthly minimum, no contract and no per-seat fees. Docusign's API plans need a sales conversation before you see a price.

OK, I'm in. How do I start?

Sign up, copy your API key, send an envelope. There is no approval step and no sales call. Get started with Firma.dev for free, no credit card required.
