Automated Quality
Intelligence
for Modern Software
One engine. 9,200+ unique rules. 75 languages. 36 frameworks. Zero cloud dependency. Your code never leaves your machine.
Five Ways to Use Krowcode
One analysis engine, five consumption surfaces — pick the one that fits your workflow.
VS Code Extension
Real-time diagnostics, code lenses, quality dashboard — right in your editor.
CLI Tool
14 commands for CI/CD, automation, batch analysis, watch mode, and git hooks.
MCP Server
8 tools for AI assistants — Claude, Copilot, and any MCP-compatible client.
Language Server
Editor-agnostic LSP for Vim, Neovim, Sublime Text, and more.
Self-Hosted Dashboard
Team-wide metrics, trends, quality gates, alerts — fully self-hosted.
Built for Serious Engineering
Every feature is designed to catch real issues without drowning you in noise.
Security First
SQL injection, XSS, CSRF, SSRF, hardcoded secrets — 579 security rules catch vulnerabilities before they ship.
Blazing Fast
LRU cache, SHA-256 incremental analysis, lazy rule loading, parallel pool — sub-second for most files.
Privacy First
Everything runs locally. Your code never leaves your machine. Zero cloud dependency for core analysis.
False Positive Defense
3-layer FP detection: rule engine suppression, smart post-analysis filtering, and user config overrides.
Git Integration
Pre-commit hooks, diff analysis against branches, watch mode with debouncing — fits your workflow.
Auto-Fix System
6 fixable rule types with tiered safety (100%/99%/95%), automatic backups, and daily fix reports.
15 Categories
Security, performance, complexity, dead code, maintainability, testing, API design, and 8 more categories.
Quality Scoring
0-100 scores with A-F letter grades, trend tracking, and quality gates for CI/CD enforcement.
75 Languages
TypeScript, Python, Go, Rust, Java, C#, PHP, Ruby, Kotlin, Swift, and 65 more — one engine covers all.
