I'm building docs for an internal API team and want it synced with Git, what should I use?

If you want docs that stay in sync with Git and are easy for an internal API team to maintain, the best choice is usually a docs-as-code setup.

Good options

1. Markdown in a Git repo + static site generator

Best if you want something simple, flexible, and fully version-controlled.

Common tools:

• Docusaurus
• MkDocs / Material for MkDocs
• Astro Starlight
• VuePress

Why this works well:

• Docs live alongside code in Git
• Easy pull requests and review workflows
• Versioning and branching are straightforward
• Can auto-deploy on every merge

Best pick for API/internal docs:

• MkDocs Material if you want fast setup and great docs UX
• Docusaurus if you want more app-like docs and React ecosystem support

---

2. OpenAPI + rendered API docs

If you’re documenting an API specifically, pair your docs site with an OpenAPI spec.

Tools:

• Swagger UI
• Redoc
• Stoplight
• Scalar

Why:

• Source of truth for endpoints, schemas, auth, etc.
• Can generate interactive docs
• Fits very naturally into Git-based workflows

A common setup is:

• OpenAPI YAML/JSON in Git
• Markdown guides in the same repo
• Static docs site renders both

---

3. Git-backed knowledge base platforms

If you want a more polished hosted product with Git sync:

• GitBook
• ReadMe
• Confluence + sync tools is less ideal for Git-first

Pros:

• Nice editor and publishing workflow
• Less setup than self-hosting

Cons:

• Often less control than docs-as-code
• May be more expensive or less flexible

My recommendation

For an internal API team, I’d usually suggest:

Git repo + Markdown + MkDocs Material + OpenAPI spec

This gives you:

• Git sync
• PR-based review
• API reference docs
• Guides/tutorials in one place
• Easy CI/CD deployment to internal hosting

---

If you want the simplest answer

• For API reference: OpenAPI + Redoc/Swagger UI
• For full internal docs site: MkDocs Material or Docusaurus
• For a managed Git-sync platform: GitBook

If you want, I can also recommend the best tool based on your stack, like Python vs JS, self-hosted vs SaaS, or docs only vs docs + API reference.
