The GitHub Wiki alternative for when the repo wiki runs out
Last updated September 9, 2026
A repository wiki is the right first move — free, already there, and a real git repo you can clone. Teams outgrow it in predictable ways, and GitHub’s own documentation names most of them: no page hierarchy beyond a hand-written sidebar, no pull requests or review on an edit, permissions welded to the repository, a soft limit of 5,000 files, and search engines that only index a wiki if the repo has 500 or more stars and public editing is turned off. tela is where that knowledge goes next.
tela vs GitHub Wiki, at a glance
| Feature | tela | GitHub Wiki |
|---|---|---|
| Structure | Nested spaces and pages, backlinks, related pages | A flat page list plus a hand-maintained _Sidebar |
| Permissions | Organizations, groups, per-space roles, invite by email, Google/Microsoft/GitHub sign-in; per-org SSO on Enterprise | Tied to the repo — public, or collaborators only |
| Search | Built in — ranked full-text always, plus semantic Ask that cites its sources (self-host brings its own model) | Its own siloed wiki search; wikis are not in code search |
| Found by search engines | Publish a whole space to the open web — no-login reader, clean /handle/space URLs, RSS and a sitemap | Only for repos with 500+ stars and public editing disabled |
| Agents read & write (MCP) | Built in — agents read and write, scoped per token, over a hosted endpoint | GitHub’s official MCP server ships no wiki tools |
| Generate docs from your code | Yes — Atlas builds a cited, coverage-checked wiki from git repos and Jira | No |
| Still a folder you can clone | Two-way — mount /dav/ as a folder of .md files with any WebDAV client, or bisync it with rclone | Yes — the wiki is a git repository |
Why teams switch to tela
- Real structure and real permissions — nested spaces, organizations and per-space roles, instead of a flat page list whose access is whatever the repo’s happens to be.
- Findable: ask a question and get an answer with citations, and publish a space search engines will actually index — a no-login reader with RSS and a sitemap, on any repo, at any star count.
- You do not lose the clone-it-locally habit: every space mounts over WebDAV as a folder of .md files and bisyncs both ways, so the local copy stays a first-class way to work.
- Agents write it — GitHub’s own MCP server exposes issues, pull requests and code, but no wiki tools at all.
When GitHub Wiki is the better choice
For a small project the repo wiki is hard to argue with: nothing to host, nothing to pay for, it sits beside the code with the same access list, it renders AsciiDoc and reStructuredText as happily as markdown, and it is a git repository you can clone and edit locally with full history. If a handful of pages next to one repo is genuinely all you need, stay there.
Frequently asked questions
Is tela a good GitHub Wiki alternative?
Yes. Real structure and real permissions — nested spaces, organizations and per-space roles, instead of a flat page list whose access is whatever the repo’s happens to be. tela is open-source (AGPL-3.0), self-hostable, and markdown-native, with a built-in MCP server so AI agents read and write your docs.
Can I self-host tela and connect AI agents to it?
Yes. Self-host tela for free (AGPL-3.0) or start on the free cloud tier. Its built-in MCP server lets agents like Claude search, read and write your wiki directly, on tools scoped by the token you give them.
