Grit is a powerful technical debt management tool that uses machine learning and static analysis to automate code cleanup and framework migrations. It works with multiple languages and integrates with GitHub, VS Code and the command line. Grit is geared for high-velocity software teams, with a free version for personal and open-source use, a team version for up to 20 contributors, and an enterprise version for bigger teams.
Another strong contender is Metabob, an AI-powered coding assistant designed to help with code review, refactoring and debugging. With graph neural networks and generative AI, Metabob helps improve software security and quality by finding and fixing complex coding problems. It also offers AI code review, software security scanning and self-hosted deployment, so it can be used for legacy code maintenance and analysis of new codebases.
If you need broader language support, check out Refraction. The tool uses AI to generate code, refactor to modern standards, find bugs and convert code from one language to another. It supports more than 56 languages and can create CI/CD pipelines, so developers can concentrate on the parts of their projects that matter. A free service makes it easy to integrate, and Refraction is a good choice for developers who want to get their work done.
