$ bigbro analyze src --format sarif
Finds issues across a project with real TS diagnostics.
Built for the moments that slow you down.
TypeScript-backed scans
Run real diagnostics over your project for the issues heuristics miss, without the heavy CLI footprint.
Flexible outputs
Text for developers, JSON for tooling, ESLint for CI, SARIF for security dashboards.
From error to action in one flow.
1. Paste the error
Drop in a message, code, or stack trace. big-brocode auto-detects language and context.
2. Get the story
See why it happened, what file likely triggered it, and the fastest fix that matches your stack.
3. Scan the project
Run analyze mode to surface TypeScript diagnostics and safe autofix hints before CI does.
