## Profile

Overview: Fern (Birch Solutions, Inc.) is a developer experience platform that helps API-first companies deliver production-ready SDKs and branded API documentation from a single integrated pipeline. Founded in 2022 and headquartered in Brooklyn, New York, Fern accepts OpenAPI, AsyncAPI, gRPC, and OpenRPC specifications as input, generating idiomatic client libraries in nine programming languages alongside SEO-optimized, customizable documentation websites. Core capabilities include docs-as-code Git workflows, a live API Explorer, AI search, MCP server support for AI-agent readiness, RBAC, and SSO. Backed by $13M from Bessemer Venture Partners and Y Combinator, Fern was acquired by Postman in January 2026 for an undisclosed sum and continues to operate as an independent product. Over 200 customers—including Square, ElevenLabs, Adobe, Auth0, and Twilio—use Fern to power developer and agentic API experiences.
Product summary: Fern is an integrated API developer experience platform with two core products: the Fern SDK Generator, which produces idiomatic, production-ready client libraries across TypeScript, Python, Go, Java, C#, PHP, Ruby, Swift, and Rust from an API spec; and Fern Docs, a fully customizable API documentation platform supporting docs-as-code, AI search, interactive API Explorer, versioning, RBAC, and enterprise SSO. Both products accept OpenAPI, AsyncAPI, gRPC, and OpenRPC as input and are open source. Fern is a Postman company as of January 2026.


### Key capabilities

- SDK generation in 9 languages: TypeScript, Python, Go, Java, C#, PHP, Ruby, Swift, Rust
- Branded API documentation site with custom domain, CSS, JS, and React components
- Multi-spec input: OpenAPI, AsyncAPI, gRPC/Protobuf, OpenRPC, Fern Definition
- Docs-as-code with Git-backed versioning, PR preview deployments, and CI/CD publishing
- Live API Explorer with API key injection and SDK code snippet generation
- AI search (Ask Fern), llms.txt, and MCP server for agent-ready documentation
- Enterprise access controls: RBAC, JWT, SSO, federated authentication
- Built-in SDK features: OAuth 2.0, SSE, auto-pagination, retries with backoff, idempotency headers
- Automated semantic versioning and registry publishing for SDK packages
- SOC 2 Type II compliance and dependency vulnerability SLA



### Target users

- Developer experience (DX) engineers and developer relations teams at API-first companies
- API platform engineers managing multi-language SDK maintenance
- Technical writers building and maintaining developer portals
- CTOs and engineering leaders at companies selling public APIs
- DevOps and platform teams integrating docs and SDK publishing into CI/CD pipelines
- Enterprise teams requiring access-controlled, self-hosted API documentation



### Key use cases

- API-first companies needing idiomatic, production-ready SDKs across multiple languages
- Replacing low-quality open-source SDK generators (e.g., OpenAPI Generator)
- Publishing branded API documentation portals from existing OpenAPI or gRPC specs
- Keeping SDKs and API docs in continuous sync via CI/CD pipelines
- Enterprise developer portals with SSO, RBAC, and self-hosting requirements
- Making API documentation AI-agent-readable (llms.txt, MCP server, agent score)
- Migrating legacy docs from Mintlify, ReadMe, or Docusaurus to a managed platform
- Scaling DX teams by outsourcing SDK maintenance and documentation infrastructure

Integrations ecosystem: Fern integrates with GitHub and GitLab for source control and CI/CD-based SDK publishing. Package registry publishing is supported for npm (TypeScript), PyPI (Python), Maven (Java), RubyGems (Ruby), and Packagist (PHP). SSO integrations include Okta, Google Workspace, Microsoft Entra, GitHub, and AWS Cognito. An MCP (Model Context Protocol) server enables AI agent integration. Fern Docs supports custom JavaScript, CSS, and React components, and serves llms.txt for AI coding tool compatibility (Cursor, GitHub Copilot, ChatGPT, Claude). As a Postman company, integration with the Postman API platform is a stated roadmap direction.
Pricing summary: Fern offers separate pricing tracks for Docs and SDKs. Docs: Hobby is free forever (2 members, 250 AI credits, custom domain); Team is $150/month billed annually (5 members, 1,000 AI credits, password protection, PDF exports); Enterprise is custom (SSO, RBAC, self-hosting, dedicated support). SDKs: Basic is $250/month per SDK billed annually (up to 50 endpoints, REST only); Pro is $600/month per SDK billed annually (up to 150 endpoints, SSE, WebSockets, OAuth, dedicated Slack support); Enterprise is custom (unlimited endpoints, migration services, GitHub issue triage, custom SLAs). A 14-day free trial is available for SDK Basic plans.
Review summary: No independent third-party review platform scores (G2, Gartner Peer Insights, etc.) were found for Fern at the time of research, consistent with its early-stage profile. Customer testimonials published on the Fern website and sourced in press coverage are consistently strong, with customers citing idiomatic code quality, smooth migrations, and high-touch team support as standout attributes. Negative feedback surfaced in context includes the historical pain of maintaining open-source SDK generators before switching to Fern, suggesting a quality gap versus prior alternatives rather than criticism of Fern itself.
Competitive positioning: Fern differentiates as the only integrated platform that couples high-quality, language-idiomatic SDK generation with fully branded API documentation from a single API spec. Where pure-play docs tools (Mintlify, ReadMe, Redocly, Scalar) cover only documentation, and standalone SDK generators (Stainless) cover only SDKs, Fern positions the two as inseparable—SDKs surface inline docs while docs auto-populate SDK code snippets. Enterprise positioning emphasizes white-glove migration, embedded engineering support, and SOC 2 Type II compliance. The January 2026 acquisition by Postman adds distribution to 500,000+ Postman organizations, differentiating it further from independent competitors.
Limitations: SDK pricing is per-language per month, which can become expensive for teams requiring broad multi-language coverage. Enterprise pricing for both Docs and SDKs is undisclosed and requires a sales call. The Basic SDK plan caps at 50 endpoints and lacks SSE/WebSocket support. Swift and Rust SDK generators are newer additions with less production track record than the core languages. No self-serve trial is available for SDK plans beyond Basic. Independent third-party review coverage is sparse given the company's early stage, making it harder to benchmark quality claims externally.
