GitHub Copilot is the most widely-adopted AI coding assistant. It offers inline code suggestions, chat-based assistance, and tight integration with the GitHub ecosystem including pull requests, issues, and Actions. Available in VS Code, JetBrains, Neovim, and more.
Windsurf began as Codeium's AI-first code editor, known for its Cascade agent. Cognition (the company behind Devin) bought it in 2025, and since June 2026 it ships as Devin Desktop, "the next generation of Windsurf": an agent command center with a built-in VS Code-style IDE; windsurf.com now redirects there. Plans are shared with Devin: Free, Pro at $20 a month and Max at $200, each with a usage allowance that refreshes daily and weekly, and extra usage billed at API prices.
