Free, fast AI completion plus Windsurf, an agentic IDE. Cascade is its agent: reads the codebase, plans, edits, verifies. Supports 70+ IDEs including VS Code, JetBrains, and Neovim via plugin. Self-hosted and air-gapped option for regulated teams. Now operating under the Windsurf brand as the flagship product.
No pricing data on file.
Now branded as Windsurf after the 2024 pivot — same company, same models, but the editor is the product rather than a plugin in someone else's IDE. Cascade, Windsurf's agent, runs the same multi-file edit and terminal-execution loop as Cursor's Composer, with a stronger emphasis on flow: the agent watches your edits and proactively suggests follow-up changes across the repo without explicit prompting. The free individual tier is genuinely usable, with unlimited autocomplete on proprietary models, which is rare in the category.
Best fit for individual engineers and small teams that want Cursor-class agent capability without the price tag, and for organizations that need on-prem or VPC deployment — Codeium has shipped self-hosted enterprise installs since before Cursor was a company. Engineers coming from VS Code adapt in an afternoon.
Watch out for: the proprietary model is competent but lags Anthropic and OpenAI flagship models on hard reasoning tasks, and the model-selection story is less flexible than Cursor's. The recent rebrand has fragmented documentation, and the legacy Codeium plugin for JetBrains and Neovim is on a slower release cadence than the Windsurf editor itself.
