Your PRs deserve a second pair of eyes.
One that never sleeps.

Revue watches every pull request, flags security flaws, performance traps, and logic errors before they land in production. Autonomous. Persistent. Always thorough.

auth/login.ts — PR #47

Critical security finding
Loose equality (`==`) allows type coercion attacks. Switch to constant-time comparison or use your auth lib's built-in method. This pattern has been exploited in real JWT implementations.

Every PR gets a full review. Security, performance, logic, style.

What Revue catches

Security vulnerabilities

Injection risks, insecure deserialization, weak crypto, exposed secrets, SQL injection patterns. CVE-level findings, not just style hints.

Performance traps

N+1 queries, missing indexes in ORM calls, unoptimized loops, excessive memory allocation. Spots what makes production slow under load.

Logic errors

Off-by-one bugs, incorrect edge case handling, race conditions, incorrect async flow. Thinks like a senior engineer reviewing your diff.

API contract breaks

Monitors your OpenAPI schemas against live implementations. Catches interface drift before clients start failing.
