Grit is a developer tool that automatically fixes technical debt by combining static analysis (GritQL) with LLM-powered code transforms, then opening pull requests directly in GitHub. It handles framework upgrades, language conversions (e.g., JavaScript to TypeScript), and dependency migrations at scale. Teams report completing migrations up to 10x faster than manual effort. Grit integrates with GitHub, VS Code, and the CLI. Key features: - GritQL declarative pattern language for defining codebase-wide transforms - AI-generated pull requests for framework upgrades and dependency migrations - Three-phase pipeline: planning (static analysis), generation (AI transforms in sandboxes), refinement (iteration) - Pre-validated migration patterns for common stacks (JS-to-TS, React class-to-functional, etc.) - GitHub and VS Code integration with CLI support - Self-hosted option for enterprise security requirements
Free tier (CLI, open-source/personal use); Enterprise from $0.10 per build (cloud) or $0.05 per build (self-hosted)
