The Problem
Why OSS docs are almost always lacking
Building the thing is hard enough. Documenting it well is a whole second job, and most maintainers simply don't have the time or tools.
Docs are always an afterthought
You've built something great, but documenting it properly feels like a second project on top of the first. It keeps getting pushed down the to-do list.
Contributors struggle without clear guides
Contributors want to help but don't know where to start. A missing or incomplete contribution guide means friction, abandoned PRs, and a smaller community.
A README isn't enough anymore
Your README is a starting point, not a documentation site. Users expect searchable, navigable docs, not a single long Markdown file.
Good doc tools cost money you don't have
Open source projects run on nights and weekends. Most dedicated documentation platforms start at $50–100/month, not a reasonable ask for a side project.

FAQ
Docs for open source projects: common questions
Is the free plan really free forever for open source projects?
Yes. The Docsio free plan is a permanent home for open source documentation, not a trial. You get one project, AI generation from your repo or project URL, brand extraction, a hosted site with SSL, 5 AI agent edits per month for ongoing tweaks, and an auto-generated llms.txt file. No card on file, no expiry date, no surprise downgrade.
Can I use a custom domain like docs.myproject.dev on the free plan?
Yes. Custom domains with automatic SSL are included on every plan, including free. Point a CNAME at the value Docsio gives you in project settings, hit verify, and your docs live at docs.myproject.dev with no Docsio branding in the URL. You only need to upgrade if you want extras like full-text search or a chat widget.
Does Docsio sync with my GitHub repo?
Yes. Bidirectional GitHub sync is free on every plan. Connect a repository, pick a branch, and Docsio commits the docs back to your repo as signed commits. Push edits from your editor or from the Docsio UI, and the other side updates. Contributors can keep using normal pull request workflows for prose changes.
Can I generate API reference docs from my OpenAPI spec?
Yes. Point Docsio at your repo, project site, or a hosted OpenAPI file and the AI agent will write reference pages for each endpoint with request and response examples. You can then ask the agent to add SDK snippets, fix descriptions, or reorganize the sidebar. The free plan covers initial generation; the Pro plan removes the monthly edit cap for ongoing changes.
Do I have to self-host the docs site?
No. Docsio hosts the published site for you on a fast global edge, with SSL handled automatically. You hit Publish and the live URL updates. If you prefer to self-host, you can still use GitHub sync to keep a copy of the Markdown in your repository and deploy that copy anywhere you like.
When would an OSS project actually need to upgrade to Pro?
Most OSS projects never need to. You only need Pro if you want unlimited AI agent edits, full-text search across pages, password-protected sections, doc versioning for tagged releases, an in-app AI chat widget, or the MCP server endpoint. For a typical project README, getting started guide, and contributor docs, the free plan is enough.
