CODEOWNERS file for GitHub, GitLab, or Bitbucket by adding pattern rules with global or per-rule syntax. Includes a root default owner, a defensive final catch-all, the correct platform banner, and ready-to-save output.CODEOWNERS File Generator
Generate a CODEOWNERS file for GitHub, GitLab, or Bitbucket that auto-assigns reviewers.

/docs/ — directory; src/** or src/lib/*.js — files.
@team GitHub team, %group GitLab, @user.email.com for emails.

Frequently Asked Questions
What is CODEOWNERS?
A plain text file (CODEOWNERS) that the platform reads to auto-assign reviewers or restrict merges for matching paths. GitHub, GitLab, and Bitbucket all support it with slightly different syntax.
Where does the file go?
GitHub reads .github/CODEOWNERS, docs/CODEOWNERS, or the root CODEOWNERS. GitLab reads CODEOWNERS or .gitlab/CODEOWNERS, and Bitbucket reads CODEOWNERS at the repo root.
What does the * rule do?
The * line sets the default owner for every path not matched by a more specific rule. Rules are matched longest-first, so more specific patterns override it.
Can teams be owners?
On GitHub yes — @team is valid if the team can be mentioned on the repo. GitLab uses %group or %subgroup, and Bitbucket supports user groups and projects.
How are rules matched?
The platform scans top to bottom and applies the rule with the longest matching pattern. Trailing * matches suffixes, and leading * matches directory prefixes.
Does it handle emails or usernames?
Yes. GitHub and Bitbucket accept user emails; GitHub also accepts usernames. Tabs or, on GitHub, whitespace separate the pattern from the owners.
Are comments allowed?
Yes — lines starting with # are comments, and the generator includes an informative header with a timestamp and platform note.
Is my data uploaded?
No. Everything is assembled in your browser. The generated file is ready to save as CODEOWNERS or paste into your platform.
