Refact.ai
Overview
Refact.ai is an open-source, autonomous AI agent designed to act as a proactive developer teammate. It combines its own state-of-the-art Refact 1.6B model with leading third-party LLMs (including Qwen2.5-Coder, GPT-4, and StarCoder) to plan, execute, and verify complex coding tasks. The platform prioritizes privacy and flexibility, offering robust self-hosting options (air-gapped capable) and the ability to fine-tune models on your organization's specific codebase. With support for the Model Context Protocol (MCP), Refact.ai integrates deeply with your IDE, databases, and other tools to deliver context-aware code completion, chat, and refactoring.
Use Cases
End-to-End Task Delegation
Delegate multi-step coding tasks to the autonomous agent, which plans, executes, and verifies changes step-by-step within your IDE.
Secure Offline Development
Deploy Refact.ai on-premise or in a private cloud to ensure zero telemetry and complete data sovereignty for sensitive projects.
Custom Model Fine-Tuning
Fine-tune LLMs on your company's proprietary codebase to improve suggestion accuracy and adherence to internal coding standards.
Multi-Model Workflows
Seamlessly switch between the ultra-fast Refact 1.6B model for completion and powerful reasoning models for complex architecture.
