Refact.ai: The #1 Open-Source AI Agent for Software Development

Refact.ai stands out as the premier open-source AI agent designed to revolutionize software development workflows. It adapts seamlessly to your coding style, offers comprehensive context awareness, and automates key tasks such as coding, debugging, and testing. As a viable open-source alternative to tools like Cursor and Copilot, Refact.ai provides developers with unparalleled control and flexibility.

What is Refact.ai?

Refact.ai is an autonomous AI agent that acts as an AI programming partner, capable of handling end-to-end coding tasks. It understands your codebase, integrates with your existing tools, and allows you to preview and control the entire development process. This agent not only codes like you but also thinks like you, making it an indispensable asset for any development team.

How does Refact.ai work?

Refact.ai leverages several key features to streamline the software development process:

  • Step-by-Step Task Completion: The agent meticulously plans, executes, and deploys code, mirroring the workflow of an experienced developer.
  • Repository Analysis: It thoroughly searches and analyzes your repository to ensure accurate code execution.
  • Integration Capabilities: Refact.ai connects seamlessly with GitHub, databases, CI/CD pipelines, and more, allowing for a cohesive development environment.
  • Intuitive User Experience: The agent offers a simple and intuitive UX, making it easy to integrate into your daily workflow.

Key Features and Benefits

  • Autonomous AI Agent: Delegate your coding tasks end-to-end, freeing up your time to focus on high-level strategic initiatives.
  • In-IDE Chat: Ask questions, edit code, debug, and generate new code using natural language, tailored to your project's specific needs.
  • Accurate Autocompletions: Predicts and suggests the next lines of code, functions, or classes with precision, powered by the Qwen2.5-Coder model and Retrieval-augmented generation (RAG).
  • Context-Awareness: Analyzes every symbol you type and retrieves project-specific insights to generate accurate and relevant code suggestions.

Real-World Use Cases

Developers across various industries have experienced significant benefits from using Refact.ai:

  • Denis Savin (LinkedIn): Saved thousands of euros and months of work by building a working product prototype within a week.
  • Ukro (Discord Community): Built 99.9% of an IoT cloud monitoring Django app using Refact.ai Agent, saving time and energy.
  • Ukro (Discord Community): Fixed a critical plugin issue in WordPress within 30 minutes, which was initially estimated to take 80 hours to rewrite from scratch.
  • SuperMalinge (Discord Community): Created a fully functional GUI for a worker client in just 14 minutes, a task that had been requested for weeks without delivery.
  • R3gzPro (Discord Community): Built functional web applications with zero prior web development experience, describing the agent as a personal paid developer that handles around 95% of the work.
