FAQ

Questions, answered.

Owl reviews TypeScript, JavaScript, Python, Go, Java, Kotlin, Rust, Ruby, and more. Language-specific checks are deepest for the most common ecosystems.

When a PR opens or updates, Owl reads the diff plus relevant surrounding code, runs analysis across bugs, security, performance and quality, then posts a summary and inline comments.

Owl indexes the repository structure and pulls in related files — types, callers, tests — as context for each change it reviews.

Code is transferred over TLS, processed in isolated environments, and access is scoped to the repositories you grant.

Yes. Add a .owl/rules.yml to define conventions, severities, and path-specific rules shared across your team.

Owl only retains what is needed to complete a review. Retention settings are configurable on Team and Enterprise plans.

Through a GitHub App. Owl publishes its findings as a native GitHub review with inline comments and an approve / request-changes status.

Yes — the Free plan covers personal repositories with a monthly review allowance.

Your next pull request deserves a second pair of eyes.
