Self-Verifying Fixes
Doesn't just guess. It actively runs your tests (like npm run build) to mathematically prove the environment is fixed.
The open-source AI agent that detects, diagnoses, and fixes broken local development environments.

The DevFix command-line interface.

Case DEV-02: Diagnosing missing environment variables and creating .env configuration

DevFix is an AI-powered CLI tool designed to solve the headache of broken local environments.

The devfix inspect . command instantly analyzing a broken project's runtime, package manager, and sandbox requirements.

DevFix started as an experiment to see if LLMs could reliably troubleshoot broken configurations without human intervention. We succeeded in building a framework that achieves high recovery rates on severely broken projects.
Today, DevFix is evolving into a serious, everyday developer tool.
We are actively designing a VS Code Extension, adding support for Rust and Go, and building custom verifier integrations. We are looking for contributors! Check out our Roadmap and jump into our GitHub repository to submit your first Pull Request.
