Four steps from git push to inline review
PR Opened
Webhook fires the moment a PR is opened or pushed. Signature verified.
Diff Analyzed
Lockfiles, vendor dirs, generated code, and binaries are skipped automatically.
Agent Reviews
A LangGraph agent runs Claude alongside ruff. Real linter output, real reasoning.
Comments Posted
Findings appear as inline comments on the diff — exactly where the issue lives.
Built for teams who care about review quality
PrSentry is opinionated about what makes a useful review. No noise, no nitpicks unless you ask for them.
Inline on the Diff
Comments appear exactly where the issue is, not in a wall of text at the bottom of the PR.
Grounded in Static Analysis
Runs ruff on Python code so findings are backed by real linter output, not just vibes.
Smart Filtering
Skips lockfiles, vendor dirs, binaries, and generated code automatically. Reviews what matters.
Cost Control
Token budgets per file and per PR. Hard ceilings prevent surprise bills.
Full Observability
Langfuse tracing for every agent run. See exactly what Claude saw and did.
Run History
Postgres stores every review: status, duration, comments posted, errors.
