What is CODEOWNERS Generator?
The CODEOWNERS Generator builds GitHub CODEOWNERS files through a visual rule builder: each rule maps a file path pattern to owning teams or users. Syntax warnings flag common mistakes, and the output matches the exact format GitHub expects.
Key Benefits
- Automatic reviewer assignment by directory or file pattern
- Syntax warnings prevent silent CODEOWNERS misconfiguration
- Live output regeneration as rules change
- No GitHub login required to draft the file
Common Use Cases
- •Setting up code review requirements for a new repository
- •Assigning frontend, backend, and docs teams to their directories
- •Ensuring security-sensitive files have mandatory reviewers
- •Standardizing ownership across an organization
- •Migrating ownership rules between repositories
Generate a CODEOWNERS File
- Add ownership rules: For each rule, enter a file path pattern (e.g. /src/components/) and the owning team or user (e.g. @owner/frontend).
- Order matters: Later rules take precedence over earlier ones. Put general patterns first and specific overrides last.
- Check syntax warnings: Patterns missing a leading / or without a file extension are flagged so GitHub can match them correctly.
- Save the file: Copy the output and save it as .github/CODEOWNERS in your repository root branch.
Key Features
- Visual rule builder: pattern + owners per row
- Syntax validation for glob patterns (leading /, file extensions)
- Multiple owners space-separated per rule
- Output format matches .github/CODEOWNERS exactly
- Live regeneration as you edit rules
- Works offline - team data stays on your device
