Windsurf
by Codeium
Codeium's IDE-with-an-agent. Cascade flow combines deep context with autonomous multi-file work.

Windsurf
Added 17 May 2026
Overview
Windsurf is Codeium's AI-native editor, built around the Cascade flow: a chat-like interface that maintains continuous context across files, terminal commands, and edits. Acquired by OpenAI in 2025, then reshaped, Windsurf remains a serious Cursor competitor with a more agent-first lean.
Best for
Best for
Engineers who want continuous agent context, not chat-and-snippet
Use cases
- Multi-file refactors with continuous context
- Daily IDE work for engineers who prefer a Cascade-style flow
- Long-running tasks that need terminal and file access in one session
- Teams already on Codeium completions wanting a full IDE
Notes
Why it matters
Windsurf is the credible third option in AI-native editors, sitting between Cursor’s product polish and Claude Code’s terminal purity.
How teams use it in production
Teams that liked Codeium’s completions but wanted a deeper agent experience drop in here. Cascade is genuinely a different flow than Cursor’s Composer, worth trying before committing.
What to watch
The OpenAI acquisition aftermath is still unfolding. Treat Windsurf as in motion, not stable, when planning multi-year tool commitments.
Pros
- Cascade flow handles multi-step work elegantly
- Strong code understanding across large codebases
- Active development under OpenAI stewardship
- Generous free tier compared to Cursor
Cons
- Future direction less certain after the acquisition reshuffle
- Smaller ecosystem than Cursor
- Some friction switching from VS Code muscle memory
