Open-source Mintlify alternative
A modern docs experience without the SaaS — MIT-licensed, self-hostable, and yours to own.
The open-source Mintlify alternative
Mintlify is a polished hosted docs platform — but it's a paid SaaS: your content and build pipeline run on someone else's infrastructure, with per-seat pricing and the usual platform lock-in. Markline gives you the same modern docs experience as an MIT-licensed framework you fully own and self-host.
Why teams switch
- Own your stack. Markline builds to plain static HTML you host anywhere — GitHub Pages, S3/CloudFront, Cloudflare, or your own CDN. No vendor runtime.
- No per-seat pricing. It's MIT-licensed and free; add editors without a bill.
- Bring your own AI key. The Ask-AI assistant runs on your LLM key (BYOK), not a metered hosted add-on.
- First-class OpenAPI. A generated API reference with an interactive playground, three-pane layout, and per-language code samples.
- No lock-in. Your content is MDX in your repo; the engine is open source.

Migrate in minutes
Markline reads MDX guide pages and an openapi.json, so moving over is mostly
copying content. Point it at your docs and spec, set your theme, and ship:
