Every layer optimized for speed — from the byte-level scanner to the multi-threaded worker pool.
Web Worker pool utilizing all CPU cores for parallel analysis. State-machine parser processes 10,000+ files per second.
Direct Uint8Array scanning — no string allocation. ASCII fast-path skips TextDecoder entirely for maximum throughput.
Comment-aware detection for JavaScript, TypeScript, Python, Go, Rust, Java, C++, and 50+ more languages.
Runs entirely in your browser. No server, no backend, no telemetry. Your code never leaves your device.
Cyclomatic complexity, maintainability index, technical debt ratio, duplicate detection, and quality scores.
Interactive treemaps, donut charts, heatmaps, and animated dashboards built with Framer Motion.
No signup. No upload. No tracking. Just pure, fast analysis.
