AI code editor by Codeium with Cascade agent for autonomous multi-step coding tasks.
Windsurf is an AI code editor by Codeium with Cascade agent for autonomous multi-step coding tasks. Cascade agent runs multi-step tasks with terminal command execution and file edits.
About Windsurf
Windsurf is an AI code editor from Codeium, built around Cascade — an agent that carries out multi-step coding tasks, running terminal commands and editing files on its own.
Where many editors stop at autocomplete, Windsurf leans into autonomy: Cascade chains steps across a project, and its in-editor Flows system keeps context as it works.
It suits people who want the agent to drive longer stretches of work, and the free tier — flagship models, no credit card — makes it easy to try. Two caveats: the extension ecosystem is smaller than VS Code-based editors, and premium-credit use can be hard to predict on long agent sessions.
It's the agent-forward option next to Cursor, which stays closer to a classic IDE, and terminal-first Claude Code.
