About Codeium

Codeium now primarily refers to the plugin ecosystem for developers who stay in JetBrains, VS Code, Vim, or other editors. The company's flagship IDE became Windsurf, was acquired by Cognition in 2025, and rebranded to Devin Desktop in June 2026; the JetBrains plugin continues under the Windsurf name while the main editor moved to devin.ai/desktop.

Key Features

  • Free autocomplete and chat plugins for 40+ editors
  • JetBrains plugin continues under the Windsurf brand
  • Backed by Cognition's SWE coding models
  • Upgrade path into Devin Desktop and Devin Cloud agents

Pros & Cons

Pros

+ Genuinely useful free tier across many editors

+ Simple onboarding for developers new to AI coding

Cons

- Branding is confusing post-rebrand (Codeium / Windsurf / Devin Desktop)

- Full agent experience requires moving to Devin Desktop

- Roadmap follows Cognition's agent-platform strategy, not plugin users
