Windsurf from Codeium is an agentic IDE with a distinctive Cascade flow mode — a collaborative AI experience where the AI stays synced to your mental model as you code, rather than acting independently. Windsurf is positioned as 'the first agentic IDE that works in true flow with the developer.'
Windsurf is a VS Code fork with Cascade as its core AI interface. Cascade can work in Write mode (makes edits) or Chat mode (explains), and transitions fluidly based on context. It maintains awareness of your recent actions, open files, and cursor position to provide relevant suggestions. Supermaven acquisition brought low-latency autocomplete, and the multi-model support (Claude, GPT-4, DeepSeek) gives users flexibility.
Free tier: 50 prompts/month, unlimited autocomplete. Pro: $15/month. Ultimate: $60/month. Enterprise available with team features.
Individual developers, small teams, and companies looking for a cheaper Cursor alternative. Popular in the open-source community.
