tela vs Backstage TechDocs — generating docs, not just building them
Last updated September 9, 2026
TechDocs is the docs-like-code standard for platform teams: markdown beside your code, built by CI, attached to the component that owns it in the Backstage catalog. That ownership model is genuinely good, and tela does not replace a service catalog. What TechDocs does not do is write anything — it builds markdown a human already wrote, has no AI answer layer in core, and its official MCP exposes catalog and scaffolder actions rather than your docs. tela is the other half of the problem.
tela vs Backstage TechDocs, at a glance
| Feature | tela | Backstage TechDocs |
|---|---|---|
| Where the docs come from | Yes — Atlas builds a cited, coverage-checked wiki from git repos and Jira | Builds and hosts the markdown you wrote |
| Who can edit | Anyone — a WYSIWYG markdown editor in the browser | Markdown in each repo; "Edit this page" links back out to the repo |
| Ask your docs (AI) | Built in — ranked full-text always, plus semantic Ask that cites its sources (self-host brings its own model) | None in core — Lunr, Postgres or Elasticsearch search |
| Agents read & write (MCP) | Built in — agents read and write, scoped per token, over a hosted endpoint | Official MCP for catalog/scaffolder actions; no TechDocs actions |
| Ownership & discovery | Spaces, backlinks, related pages, semantic search | Stronger — docs hang off a catalog entity and inherit its owner |
| Coverage | Atlas scores generated pages against the code's real surface — routes, flags, env vars, models — and names what is still undocumented | No coverage measure; a page exists or it does not |
| To run it | A docker-compose stack, or the free cloud tier | A Backstage monorepo you own, a CI job per repo, plus S3/GCS for output |
Why teams switch to tela
- Atlas writes the first draft from the repo and flags what is not covered; TechDocs only builds pages somebody already wrote.
- Undocumented surface becomes a number instead of a hunch — Atlas audits generated pages against an inventory of the code's routes, flags, env vars and models, and lists the gaps.
- Answers with citations over the whole wiki, instead of Lunr or an Elasticsearch cluster you operate yourself.
- Non-engineers can contribute — editing is a browser, not a pull request into each service repo — while engineers who want the files can still mount the space as a folder of .md.
When Backstage TechDocs is the better choice
If you already run Backstage, TechDocs is the right home for service documentation, and tela does not try to replace the software catalog. Docs living in the repo means they are versioned with the code, reviewed in the same pull request, and inherit an owner — so a stale or unowned doc shows up as a catalog problem rather than going quietly unnoticed. That coupling is precisely what a standalone wiki gives up.
Frequently asked questions
Is tela a good Backstage TechDocs alternative?
Yes. Atlas writes the first draft from the repo and flags what is not covered; TechDocs only builds pages somebody already wrote. 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.
