AGPL-licensed e-signature you can self-host, read the source of, and embed in your own product
Documenso is an open-source, AGPL-licensed electronic signature platform positioned as an alternative to DocuSign, available both as a hosted service with a free tier and as a fully self-hostable application, offering multi-recipient signing workflows, reusable templates, direct signing links, embedded and white-label signing, a REST API with webhooks, and compliance coverage including SOC 2, HIPAA, 21 CFR Part 11, ESIGN, and UETA.
Overview
Documenso started in January 2023 as a public GitHub project with a simple thesis: document signing is infrastructure, and infrastructure this important should not be a closed box owned by one vendor. Founders Timur Ercan and Lucas Smith raised a $1.54M pre-seed from OSS Capital, ran the company as an open startup with public metrics and a public roadmap, and built the product in the open on a modern TypeScript stack (React Router v7, Hono, Prisma and PostgreSQL, tRPC). The repository has passed 14,000 stars.
The product itself is a competent, focused e-signature tool rather than a proposal platform. You upload a document, place fields, define signing order across recipients, and send. Templates make repeat documents reusable, Direct Links let anyone start a signing flow on demand, embedded signing puts the experience inside your own React or Vue application, and the REST API with webhooks automates document creation and user management. Documenso 2.0 in late 2024 introduced envelopes, a rebuilt editor, and API V2.
What distinguishes Documenso in 2026 is that it takes the cryptography seriously. The company has been publishing a Building Documenso series on signature trust infrastructure, added external certificate authority support through CSC 2.0 so signatures can chain to real trust anchors rather than a vendor's self-signed certificate, and achieved HIPAA compliance in March 2026 alongside SOC 2, 21 CFR Part 11, ESIGN, and UETA. Cloud pricing is Free (5 documents a month), Individual at $25 a month, Teams at $40 a month for five users, and Platform at $250 a month, all billed yearly, with self-hosting licensed separately.
Best for
Engineering-led startups and privacy-sensitive organizations that want signing they can inspect, extend, or run themselves: developers embedding signature flows into their own product, teams with data-residency or code-audit requirements, and open-source-first companies that prefer to build on AGPL software rather than rent a proprietary SaaS.
Not the right fit for
- Non-technical small businesses that just want cheap signing. SignWell is $10 a month for unlimited documents against Documenso's $25 Individual plan, with a bigger free allowance and a longer operational track record.
- Anyone needing proposal authoring, interactive quoting, or engagement analytics; Documenso signs documents, it does not help you write or sell them.
- Teams that want self-hosting to be free and supported. The community edition is AGPL and free to run, but AGPL obligations apply if you distribute a modified version, and supported self-hosting requires a commercial license.
- Organizations that cannot absorb the operational cost of running a signing service: PostgreSQL, mail delivery, key management, backups, and upgrades all become your responsibility once you self-host.
- Buyers who want a long vendor history. Documenso is roughly three years old, and in June 2026 it paused external pull requests over supply-chain security concerns, which is prudent but a reminder of how young the project is.
How it works
- 1
On the cloud service you sign up, upload a PDF, and drag signature, name, date, text, and other fields onto it, assigning each to a named recipient. Recipients sign in the browser, in an order you control, and Documenso records the result with an audit trail. The free tier covers five documents a month with up to ten recipients each and needs no credit card.
- 2
Templates turn a recurring agreement into a one-click send. Direct Links go further: publish a template as a URL so anyone can initiate and complete the document themselves, which suits NDAs, waivers, and self-serve contract flows without a sender in the loop.
- 3
For product teams, embedded signing puts the Documenso signing experience inside your own application, with a whitelabel option on the Platform plan. The REST API creates documents, manages recipients and users, and drives workflows programmatically, with webhooks pushing completion events back. React and Vue embedding helpers and a Zapier connector cover the common integration paths.
- 4
Self-hosting is the path that makes Documenso structurally different. The AGPL-3.0 codebase deploys via Docker and Docker Compose, one-click templates on Railway, Render, Koyeb, and Elestio, Kubernetes, or manual installation, giving you the documents, the database, and the signing keys on infrastructure you control. Commercial self-hosted licensing (Business Edition and an Enterprise License) adds support and compliance features on top of the community edition.
Feature breakdown
24 features in 5 modulesSigning and workflows
The core signing engine, rebuilt around envelopes in version 2.- Multi-recipient signing with order
- Documents route to several recipients with a configurable signing sequence, covering both simple and complex agreement scenarios.
- Envelopes
- Introduced with Documenso 2.0 in November 2024, envelopes group related documents into a single signing transaction rather than sending each file separately.
- Rebuilt document editor
- The 2.0 editor reworked field placement and document preparation, shipping alongside API V2.
- Audit trail
- Every signing action is recorded for evidentiary purposes, supporting the ESIGN and UETA compliance claims.
- Multi-language support
- Internationalization is built in via Lingui, so signing pages can be presented in the recipient's language.
Templates and self-serve signing
Making repeat documents into a one-step flow.- Reusable templates
- Field layouts and recipient roles saved once and reused for documents you send repeatedly.
- Direct Links
- Launched in June 2024, a template can be published as a public link so recipients initiate and complete the signing themselves without a sender.
- Profiles
- A public profile page shipped alongside Direct Links, letting individuals or teams host their signable documents at a shareable address.
- Template store
- A shared template marketplace is listed on the product site as coming soon rather than available today.
Developer platform
The strongest argument for choosing Documenso over a cheaper hosted tool.- REST API
- API V2 shipped with Documenso 2.0 and covers document creation, recipient and user management, and workflow automation. Included for personal use on Individual, for automation on Teams, and unlimited on Platform.
- Embedded signing
- The signing experience embeds directly into your application; Teams includes embedded signing and Platform adds whitelabel branding.
- React and Vue embedding
- Framework-specific helpers rather than a raw iframe, which shortens integration time for typical web stacks.
- Webhooks
- Event callbacks keep your own system in sync with signing status without polling the API.
- Open source codebase
- AGPL-3.0 licensed TypeScript on React Router v7, Hono, Prisma with PostgreSQL, tRPC, and shadcn/ui, with over 14,000 GitHub stars and 3,000 forks.
Self-hosting and deployment
The capability no other product in this category offers.- Docker and Docker Compose
- The standard deployment path; the repository ships compose files for a full stack including PostgreSQL.
- One-click platform deploys
- Templates for Railway, Render, Koyeb, and Elestio for teams that want self-hosting without managing servers.
- Kubernetes and manual deployment
- Supported for organizations running their own orchestration or with specific infrastructure policies.
- Business Edition and Enterprise License
- Commercial self-hosted licensing adds support, compliance, and admin features on top of the free community edition, with an upgrade path documented in the vendor's FAQ.
- Full data control
- Documents, database, and signing keys stay on infrastructure you own, which is the deciding factor for regulated and data-residency-constrained buyers.
Trust, cryptography, and compliance
Where Documenso has invested most heavily in 2026.- External certificate authority support
- CSC 2.0 support, detailed in the vendor's August 2026 writing, lets signatures chain to external certificate authorities rather than relying on a platform-issued certificate.
- SOC 2 and HIPAA
- SOC 2 is claimed on the product site, and HIPAA compliance was announced in March 2026.
- 21 CFR Part 11, ESIGN, and UETA
- Regulated life-sciences workflows and US electronic signature law are both covered by the published compliance set.
- Open startup transparency
- The company publishes its metrics, finances, and learnings publicly, which is a materially different diligence posture from a closed vendor.
- Supply-chain security posture
- In June 2026 the project paused external pull requests to address supply-chain attack concerns, an unusual but defensible move for security-critical open source.
Use cases
4 documentedDeveloper embedding signing into a SaaS product
The application needs customers to sign agreements in-app, and the incumbent e-signature vendor's platform tier costs more than the feature is worth at current volume.
Documenso's embedded signing with React helpers goes into the product on the $40 Teams plan, or the whole thing is self-hosted so signing volume never becomes a line item.
Health tech startup with data-residency constraints
Patient-adjacent agreements cannot leave a specific jurisdiction, and no hosted signing vendor will commit to the required residency at a startup price.
Self-hosting on the company's own infrastructure puts documents and keys inside the compliance boundary, with HIPAA compliance and 21 CFR Part 11 coverage on the product side.
Open-source company signing contributor agreements
Contributor license agreements need to be signed at volume by people who are ideologically hostile to proprietary tooling.
A Direct Link to a template lets contributors sign themselves, on a platform whose source they can read, which removes the objection entirely.
Founder replacing a DocuSign subscription
A legacy per-envelope contract renews annually at several thousand dollars for a handful of documents a month.
The free tier covers five documents a month at zero cost and Individual at $25 covers unlimited signing, with the option to move to self-hosting later without changing product.
Pricing
from $25/mo (Individual, $300 billed yearly)Hosted plans billed yearly, from a permanent free tier to a $250 per month platform plan, with self-hosting available separately under the AGPL community edition or a commercial Business Edition or Enterprise License.
| Plan | Price | Includes |
|---|---|---|
| Free | $0 per month |
Genuinely free rather than a trial, though the five-document ceiling is tighter than it sounds for an active business. |
| Individual | $25 per month, $300 billed yearly |
The company advertises a $60 saving against the equivalent monthly rate. |
| Teams | $40 per month, $480 billed yearly |
At $8 per additional user, this is the most seat-friendly plan in the category for a growing team. |
| Platform | $250 per month, $3,000 billed yearly |
|
| Enterprise | Custom cloud or self-hosted |
|
Add-ons
- Additional Teams users ($8 per user per month)
- Self-hosted licensing (Not published): The AGPL community edition is free to run. Business Edition and the Enterprise License add support and compliance features and are quoted directly; multi-year and custom terms are offered.
Billing notes
- Prices are US dollars as published in August 2026. Every paid plan on the pricing page is presented as billed yearly, so the effective commitment is annual even though the price is shown per month.
- Self-hosting the AGPL community edition is free of licence cost but not free of obligation: AGPL-3.0 copyleft terms apply, and running it yourself means owning PostgreSQL, mail delivery, key management, and upgrades.
- The pricing tiers separate API use by purpose: personal use on Individual, automation on Teams, unlimited on Platform, so read the intended use terms before building on the cheaper plan.
- Embedded signing requires Teams; whitelabel embedded signing requires Platform at $250 per month, which is the real gate for anyone shipping signing inside their own branded product.
- The free tier's five documents per month is roughly the same shape as SignWell's three, but SignWell's paid entry is $10 against Documenso's $25.
Value assessment: Judged purely as hosted e-signature for a small business, Documenso is not the cheapest option: SignWell does unlimited documents for $10 a month against $25 here, and has more years of operational history. What you are actually buying is optionality. The AGPL codebase means you can run the same product yourself if pricing, residency, or vendor risk ever changes, and the Teams plan at $40 for five users with $8 additions is the best per-seat economics in the category for a team building signing into a workflow. If open source and self-hosting are worth nothing to you, buy SignWell. If they are worth anything at all, Documenso is priced fairly for what it uniquely offers.
Strengths & limitations
Strengths
- The only product in this category you can genuinely self-host, with Docker, Kubernetes, and one-click deploys on Railway, Render, Koyeb, and Elestio, which removes vendor lock-in as a category of risk.
- AGPL-3.0 source with over 14,000 GitHub stars means the signing logic and cryptography are auditable rather than asserted, which matters more for signatures than for most software.
- Serious investment in signature trust infrastructure: external certificate authority support via CSC 2.0 puts it ahead of most low-cost e-signature tools on cryptographic rigor.
- Strong compliance coverage for a young company: SOC 2, HIPAA (achieved March 2026), 21 CFR Part 11, ESIGN, and UETA.
- Modern developer surface: API V2, webhooks, React and Vue embedding helpers, and whitelabel embedded signing on Platform.
- Open startup transparency, with public metrics, finances, and roadmap, gives buyers unusually good visibility into vendor health.
- Teams pricing at $40 per month for five users with $8 additions is materially cheaper per head than any per-seat rival here.
Limitations
- More expensive than SignWell for the same hosted job: $25 per month against $10, with a five-document free tier against three but no unlimited-document plan below $25.
- Self-hosting is free of licence cost but not free: you own PostgreSQL, mail delivery, key management, backups, and upgrades, and the AGPL's copyleft terms bind anyone distributing a modified version.
- Whitelabel embedded signing, the feature most product teams actually want, is gated to the $250 per month Platform plan.
- The project is roughly three years old and paused external pull requests in June 2026 over supply-chain security concerns; that is a responsible decision, but it signals a young security posture rather than a settled one.
- No proposal authoring, quoting, content library, or engagement analytics; this is signing infrastructure, not a sales document tool.
- Self-hosted licensing prices are not published, so budgeting a supported on-premise deployment requires a sales conversation.
- The template store advertised on the product site is still listed as coming soon.
Head-to-head comparisons
3 alternativesDocumenso vs SignWell
from $10/mo (Light, billed annually; $12 billed monthly)The same job, two philosophies. SignWell is cheaper ($10 against $25 for unlimited documents), older, bootstrapped, and already SOC 2 Type II with a broader compliance list and native integrations; Documenso is open source, self-hostable, and better suited to embedding in your own product with source you can audit. Choose SignWell if you want the paperwork to disappear at the lowest price. Choose Documenso if self-hosting, code transparency, or long-term independence from a vendor is a requirement rather than a preference.
Full Documenso vs SignWell comparisonDocumenso vs Qwilr
from $35/user/mo (Starter, billed annually; $49 billed monthly)There is no overlap in what these do, only in the budget line they come out of. Qwilr builds and tracks interactive sales proposals with quoting and payment from $35 per user per month; Documenso signs documents that already exist, from free. A startup that buys Documenso to close deals will find it has no way to make a proposal, and a startup that buys Qwilr to sign an NDA has spent forty times what the task required.
Full Documenso vs Qwilr comparisonDocumenso vs Better Proposals
from $13/user/mo (Starter, billed annually; $19 billed monthly)Better Proposals bundles digital signatures into a $13 per user per month proposal tool with a ten-document monthly cap; Documenso separates signing out entirely and gives you the source code. If your documents are persuasive sales material, Better Proposals wins and Documenso cannot help. If your documents are contracts, agreements, and forms that need to be signed reliably (or signed inside your own application), Documenso is the correct layer and Better Proposals is the wrong shape.
Full Documenso vs Better Proposals comparisonImplementation & onboarding
- Setup time
- Minutes on the hosted free plan: sign up, upload, place fields, send. A self-hosted Docker Compose deployment is an afternoon for someone comfortable with PostgreSQL and SMTP configuration, and a production-grade self-hosted install with backups, monitoring, and key management is a multi-day project.
- Learning curve
- Low for the hosted product; the interface is conventional e-signature. Moderate for embedded signing and API work, and genuinely operational for self-hosting, where the learning curve is infrastructure rather than product.
- Onboarding
- Entirely self-serve on the cloud plans with email support on Individual and Teams, Slack integration support on Platform, and a documented upgrade path from the community edition to Business Edition. Local development needs Node.js v22 or later and PostgreSQL, with a quick start via a single npm command.
- Migration notes
- Templates must be rebuilt when moving from DocuSign or a similar vendor, since field layouts do not transfer. The migration worth planning carefully is the one between Documenso deployments: moving from the hosted cloud to self-hosted (or from community edition to Business Edition) is documented by the vendor but involves database and configuration work rather than a button. Export and archive completed documents from any outgoing vendor before cancelling, as the audit trail stays with the system that generated it.
Platform, API & security

- API
- REST API V2 shipped with Documenso 2.0, covering document creation, recipient and user management, and workflow automation, with webhooks for status events. Access is scoped by plan: personal use on Individual, automation on Teams, unlimited on Platform.
- Compliance

- Data residency
- Fully controllable when self-hosted, since documents, database, and keys run on your own infrastructure. Residency options for the hosted service are not published.
- SSO
- Not published on the pricing page; advanced admin and compliance features are positioned under the Enterprise License.
- Security notes
- The AGPL-3.0 codebase is publicly auditable, which is a stronger security claim than most vendors can make. In June 2026 the project paused external pull requests to address supply-chain attack risk. The 2026 work on external certificate authorities via CSC 2.0 addresses the trust-anchor problem that most low-cost e-signature tools leave unsolved.

Frequently asked questions
10 questionsWhat is Documenso?
Documenso is an open-source electronic signature platform positioned as an alternative to DocuSign. It handles multi-recipient signing workflows, reusable templates, direct signing links, and embedded signing, and is available both as a hosted service with a free tier and as an AGPL-3.0 licensed application you can run on your own infrastructure.
How much does Documenso cost?
The hosted service has a free plan covering five documents a month. Individual is $25 a month ($300 billed yearly), Teams is $40 a month ($480 yearly) for five users with additions at $8 each, and Platform is $250 a month ($3,000 yearly). Enterprise licensing for cloud or self-hosted deployments is quoted directly.
Is Documenso really free if I self-host it?
The community edition is AGPL-3.0 licensed and carries no licence fee, so yes in the sense that matters to most teams. But AGPL copyleft obligations apply if you distribute a modified version, supported self-hosting requires a commercial Business Edition or Enterprise License, and you take on the operational cost of PostgreSQL, mail delivery, key management, backups, and upgrades.
How do I self-host Documenso?
The repository supports Docker and Docker Compose, Kubernetes, manual deployment, and one-click templates on Railway, Render, Koyeb, and Elestio. Local development requires Node.js v22 or later and PostgreSQL, with a quick start through a single npm command documented in the README.
Are Documenso signatures legally binding?
Yes. The platform states compliance with the ESIGN Act and UETA in the United States, plus 21 CFR Part 11 for regulated life sciences workflows, SOC 2, and HIPAA as of March 2026. Its 2026 work on external certificate authority support through CSC 2.0 lets signatures chain to real trust anchors rather than a platform-issued certificate.
Can I embed Documenso signing in my own app?
Yes. Embedded signing is included on the Teams plan at $40 a month, with React and Vue helpers rather than a bare iframe, and webhooks to keep your system in sync. Whitelabel embedded signing, where the experience carries no Documenso branding, requires the $250 per month Platform plan.
Documenso or SignWell?
SignWell is cheaper and more mature as a hosted product: $10 a month for unlimited documents, SOC 2 Type II, a broader compliance list, and native integrations. Documenso wins if you need to self-host, audit the source, or embed signing deeply into your own product. For a non-technical business that just needs documents signed, SignWell is the better buy.
What is an envelope in Documenso?
Envelopes, introduced with Documenso 2.0 in November 2024, group related documents into a single signing transaction so a multi-document agreement is sent, tracked, and completed as one unit rather than as separate files. The 2.0 release also brought a rebuilt editor and API V2.
Why did Documenso stop accepting pull requests?
In June 2026 the project paused external pull requests as part of a security initiative addressing supply-chain attack concerns. For a codebase that handles signing keys and legal documents, restricting who can contribute code is a defensible precaution, though it does reduce the practical openness of an otherwise open project.
Who is behind Documenso and how is it funded?
Documenso Inc. was founded in January 2023 by Timur Ercan (CEO) and Lucas Smith (CTO), backed by a $1.54M pre-seed from OSS Capital, with third-party sources putting total early funding at roughly $2.2M. The company runs as an open startup, publishing its metrics, finances, and learnings publicly.
Editorial verdict
Documenso is the right answer to a specific question: what if the signing layer were yours? The hosted product is competent and fairly priced but not the cheapest, and a non-technical business will get more for less from SignWell. What Documenso offers that nothing else in this category does is an AGPL codebase you can read, fork, and run yourself, backed by real investment in signature trust infrastructure and a compliance set (SOC 2, HIPAA, 21 CFR Part 11) that most three-year-old companies do not have. Buy it if you are embedding signing into a product, if data residency or code auditability is a requirement, or if you want a credible exit from vendor lock-in. Buy something else if you simply want your contracts signed by Friday.
