Refact.ai

Refact.ai is an open-source autonomous AI coding agent that handles end-to-end software development tasks. It analyzes your codebase, plans execution steps, writes code, debugs issues, and integrates with your existing development tools. The platform supports self-hosted deployment for complete data privacy and offers fine-tuning capabilities to adapt to your specific coding style and stack.

• Autonomous AI Agent delegates coding tasks end-to-end, completing steps with reasoning while searching and analyzing your repository for accurate execution. It connects with GitHub, databases, CI/CD pipelines, and more.

• In-IDE Chat provides context-aware answers and suggestions tailored to your project, allowing you to ask questions, edit code, debug, and generate code using natural language.

• Accurate Autocompletions powered by Qwen2.5-Coder model and Retrieval-augmented generation (RAG) predicts next lines, functions, or classes as you type with precision.

• Multi-Model Support lets you choose from Claude 4, GPT-4o, Gemini 2.5 Pro, Grok, DeepSeek, and other leading LLMs, or bring your own API key.

• Codebase-Aware RAG analyzes your entire development environment including workspace, codebase, databases, files, documentation, and web resources for accurate context.

• Tool Integrations connect with GitHub, GitLab, Docker, PostgreSQL, MySQL, and more, handling related operations autonomously to mimic your workflow.

• Self-Hosting Option provides on-premise deployment for maximum security, keeping your code private and fully under your control with zero telemetry.

• LLM Fine-Tuning trains AI models on your organization's codebase and data for enterprise deployments, improving accuracy over time.

• Multi-IDE Support works with VS Code, JetBrains IDEs (PyCharm, WebStorm, GoLand, IntelliJ, CLion), Visual Studio, Neovim, and Sublime Text.

• 25+ Programming Languages supported including Java, Python, JavaScript, TypeScript, Rust, PHP, C++, Ruby, SQL, and more.
