OpenCode is an open-source (MIT) AI coding agent best known for its terminal TUI, now also shipping a desktop app and IDE extensions with OpenCode 2. It connects to 75+ LLM providers through models.dev, has LSP integration for real code understanding, and runs several sessions in parallel. The tool is free; for models you bring your own key, use OpenCode's free Zen models, pay as you go on Zen, or subscribe to its Go plan ($10/month, Go Plus $40).
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.
