Mintlify is the best pick for developer-first docs that live in Git and code editors, GitBook is the best pick for cross-functional teams where non-engineers also write and edit, and Document360 is the best pick for a large, structured support knowledge base. All three now write and update docs with AI assistance — the real decision is where your documentation actually lives and who's writing it.
Where Mintlify wins
Mintlify assumes documentation lives in version control, giving engineering teams full control over structure and styling the same way they control code, with an AI assistant that drafts and keeps pages current. It's the strongest fit when docs are written by developers, next to the code they describe.
Where GitBook wins
GitBook is a fully hosted editor where docs live independently of a Git repo, built for teams where engineers, product managers, support, and marketing all contribute. Choose this when documentation is a cross-functional responsibility, not just an engineering task.
Where Document360 wins
Document360 is built for larger, structured knowledge bases — auto-tagging, analytics, and workflows aimed at support and product documentation teams managing hundreds of articles rather than a single API reference. Use it once documentation has scaled past what a lighter tool can organize well.
Quick comparison
| Tool | Starting price | Core job | Best fit |
|---|---|---|---|
| Mintlify | From $0/mo | Git-based developer docs | Engineering-led documentation |
| GitBook | From $0/mo | Hosted cross-functional editor | Mixed technical and non-technical teams |
| Document360 | Custom pricing | Structured knowledge base | Large support/product doc libraries |
Which one should you use?
Choose Mintlify if your docs already live in a repo and developers are the primary writers. Choose GitBook if non-engineers need to contribute without touching Git. Choose Document360 once the knowledge base itself has grown large enough to need real organization and analytics.
FAQ
Can AI write the whole documentation set on its own? It can produce a strong first draft from code comments, PRs, or existing notes, but accuracy on anything customer-facing still needs a human review, especially for API behavior and edge cases.
Do I need to switch tools if my docs already live in Markdown? Not necessarily — Mintlify and GitBook both work well with existing Markdown content; the decision is more about workflow (Git-based vs hosted editor) than file format.
Is a dedicated docs tool worth it for a small team? Often yes even at small scale — the AI assistance and search alone save enough time that most teams outgrow a plain wiki or README quickly.
