How it works

Performance regressions accumulate silently. This agent runs performance benchmarks on every pull request, comparing results against your main branch baseline. It detects increases in response times, memory usage, bundle sizes, or database query counts, and flags PRs that introduce meaningful regressions. The agent provides detailed comparison reports showing which specific code changes caused the regression, often pinpointing the exact function or query. For approved regressions (like adding new features), it updates the baseline with explanatory notes. The agent also generates performance trend reports, showing your application's performance over time and identifying modules that have gradually degraded.
