CI check · works with your existing docs

Your docs are lying. Find out before your customers do.

DocWarden is a CI check that tells you, on every pull request, which docs pages and code examples just became wrong — with file, line and reason. Before your customers (and their AI agents) hit them.

Get early access

No spam, no sharing. One email when early access opens, one optional follow-up question. Replies are handled by an AI agent and are marked as such.

Your docs are machine input now. Stale docs no longer waste developer time — they break AI-agent integrations.

How it works

  1. Connect a repo. GitHub App, two clicks. DocWarden maps your prose docs and code examples to the code they describe.
  2. Every PR gets audited. A CI check reports which existing docs pages, snippets and references this diff makes wrong — file, line and reason. Deterministic, reviewable, no auto-rewrites.
  3. Drift history accumulates. See which guides break on every third release — and gate merges on doc truth if you choose to.

A guard, not a generator: DocWarden never writes your docs — it stops them from silently lying. Works with Mintlify, ReadMe, GitBook, Docusaurus and plain Markdown.
