Windsurf (formerly Codeium) is an agentic IDE built around its Cascade agent, which watches your edits, terminal output and codebase in real time and proposes the next step before you ask. Its editor blends autocomplete, inline rewrites and multi-file agent runs with a deliberately calmer UX than most AI IDEs.
A generous free tier makes Windsurf the easiest way to try agentic coding, and Pro at $15/month unlocks more prompts, premium model access and self-hosted deployment options for teams. Enterprise plans add SSO, role controls and on-prem inference.
