What is Refact?
Refact.ai is an open-source, autonomous AI coding agent that handles software engineering tasks end-to-end. It deeply understands codebases and integrates with developers' tools, databases, and browsers to automate complex, multi-step tasks. The agent plans, executes, and iterates until achieving successful results, working like another developer in your IDE while letting you preview and control the process.
Key features include autonomous AI agent capabilities for task delegation, in-IDE chat for asking questions and generating code in natural language, accurate real-time code autocompletions powered by Qwen2.5-Coder and Retrieval-Augmented Generation (RAG), AI code review, image-to-code conversion, and support for 25+ programming languages including Java, Python, JavaScript, Rust, PHP, C++, TypeScript, HTML, React, Ruby, SQL, C, YAML, and CSS3. Refact.ai also offers tools like AI Code Generator, Python Code Generator, and Java Code Generator.
Refact.ai is designed for individual developers, professional programmers, and enterprise teams. It works with VS Code, JetBrains IDEs, Visual Studio, Neovim, Sublime Text, PyCharm, WebStorm, GoLand, IntelliJ, and CLion. The tool supports self-hosting for on-premise deployment, allowing companies to keep their code private and maintain full data control. Enterprise customers can access LLM fine-tuning on their company's codebase, multi-GPU optimization, and priority support.
