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.
Windsurf is an AI-first IDE from Codeium, forked from VS Code, with Cascade as its primary agentic interface. Cascade monitors edits in real time and proactively suggests follow-up changes across the repository without requiring explicit invocation — a continuous background context model rather than a discrete task invocation. Multi-file editing, terminal execution, and browser integration run within the same agent loop.
The Codeium plugin delivers the same AI capabilities in VS Code, JetBrains, Neovim, and 70+ other editors for teams that cannot adopt a new IDE. Both surfaces share the same underlying model and authentication.
Self-hosted and air-gapped enterprise deployment has been available since before the Windsurf pivot. Free tier includes unlimited autocomplete. Pro plan: $15/month. Enterprise pricing via sales, includes SSO, SCIM, and VPC deployment.
Key Features
Cascade agent: monitors active edits and proactively surfaces follow-up changes across the repository without explicit invocation — operates as a continuous background context rather than a discrete task mode
Multi-file editing and terminal execution: reads and writes across the full repository and runs shell commands within a single agent session without separate context-insertion steps
Codeium plugin for 70+ IDEs: delivers the same AI completion and chat in VS Code, JetBrains, Neovim, Emacs, and others for teams that cannot adopt a new IDE
Self-hosted enterprise deployment: VPC and air-gapped installation with organization-level model routing, SSO, SCIM, and audit logs — available since before the Windsurf editor launch
Free unlimited autocomplete: Codeium's proprietary models power autocomplete at no cost for individual developers with no completion limits on the free plan
Organizational model customization (Enterprise): fine-tunes suggestions on the organization's internal codebase to reflect internal APIs, naming conventions, and architectural patterns
