Say hello to JustDocs! It's a self-hosted PHP platform for running your own documentation SaaS, in the spirit of GitBook or Mintlify, except the code, the data, and the billing are all yours.
Your customers sign up, create docs sites, write in a friendly block editor, and publish polished docs on their own domains. You run the platform on your own server, set the plans, and keep every subscription.
What you can build with it
JustDocs is made for anything people need to read and look up. One workspace can hold many sites, so the same customer can run several of these side by side:
- Product documentation and API references.
- Changelogs with dated entries and an RSS feed.
- Help centers and knowledge bases.
- Private team handbooks, open only to members.
Writing that feels easy
The block editor covers what good docs need: callouts, tabs, steps, code groups, accordions, images, and files. Work is saved as you go, with revisions to fall back on.
Already have docs somewhere else? Bring them in from Markdown, MDX, GitBook, Mintlify, or an OpenAPI file, review the import, and keep going. You can export to Mintlify-style MDX too, so nobody is locked in.
A reader your customers' readers will like
Every site gets a fast, branded reader with full-text search, an on-page table of contents, light and dark themes, and copyable code blocks. Video and Figma embeds, Mermaid diagrams, and KaTeX maths are built in, and it all works just as well on a phone.
Ready for AI, on both sides of the page
Readers can open Ask AI and get answers with citations that point back to the right pages, plus suggested questions to get them started.
AI tools are covered as well: every site serves llms.txt, a Markdown view of each page, and an MCP server, so assistants like Cursor and Claude can read the docs directly.
AI can run on your platform key, or each workspace can bring its own provider, from OpenAI, Anthropic, and Gemini to Mistral, DeepSeek, and local models through Ollama. Per-plan limits and cost tracking keep the bill predictable.
Every site, on brand
Customers style their sites beside a live desktop and phone preview: reader styles, fonts, code themes, light and dark logos, header links, an announcement banner, and custom CSS for the finishing touches. Add a custom domain and the docs feel completely their own.
Teams, private docs, and useful insights
Workspaces come with email invitations, enforced roles, and per-site access. Docs can be public, password-protected, or members-only, and drafts can be shared for review before they go live.
Insights show what readers actually need, without cookies or stored IPs: page views, top searches, searches that found nothing, page ratings and comments, AI tool visits, and broken links to fix.
Everything you need to sell it
- Workspace plans with 14-day trials, seat and storage limits, and paid features per plan.
