Side-by-side comparison — features, pricing, pros and cons
GitHub's AI pair programmer, now extended with Agent Mode for autonomous task execution and Copilot Workspace for feature-to-PR workflows. The free tier was significantly expanded in late 2025, making it the first major AI coding tool with meaningful free access. Integrates natively into VS Code, JetBrains, and GitHub.com.
Replit Agent is an AI agent built into Replit's cloud IDE that builds complete applications from natural language descriptions — writing code, installing dependencies, configuring databases, and deploying to a live URL in one workflow. Unlike browser-based tools, it runs in a full Linux container with persistent storage and supports any language Replit hosts. Aimed at developers and non-developers who want to go from idea to deployed app without a local environment.
