How It Works

From raw build log to actionable optimization in under two minutes.

01

Upload Your Build Log

Drag and drop any Make, CMake, or Ninja build log (stdout or .ninja_log). No source code required — just the output your CI already captures.

Supports logs up to 20 MB (50 MB on Pro/Team plans). 1 credit per MB analyzed.
02

Instant Waterfall Timeline

Within seconds you see every compilation unit rendered as a Gantt chart. Bottlenecks are color-coded by severity so you know exactly where time is wasted.

Detects serial bottlenecks, link-time dominance, and header explosion patterns.
03

AI Fix Recommendations

Our Gemini-powered engine generates specific, ranked recommendations: which flags to add, which headers to forward-declare, and how to restructure targets for max parallelism.

Each recommendation includes estimated time savings and copy-paste Makefile snippets.
04

Automatic PR Annotations

Connect your GitHub App and every CI run is automatically analyzed. Build regressions (> 10% slowdown) are flagged directly on the Pull Request as a review comment.

Available on Basic plan and above.
05

Slack & Teams Alerts

Get notified in your team channel when a build regresses, when credits are running low, or when a flaky build pattern is detected across multiple consecutive runs.

Configurable thresholds. Available on Pro plan and above.
