What Is Codeium and Why Did It Become Windsurf?

Codeium started as a free AI coding assistant offering inline completions, chat, and command tools across VS Code and JetBrains — with the pitch that AI coding help shouldn't require a subscription. It attracted millions of developers and became the standard free alternative to GitHub Copilot.

In late 2024, Codeium rebranded as Windsurf and expanded into a full AI-first code editor. The new centerpiece is Cascade, an agentic assistant that understands your whole codebase and can plan and execute multi-file edits, previews, and deploys. Accounts and subscriptions carried over seamlessly.

Codeium Features: Completions, Chat & Cascade

Windsurf keeps the free assistant roots and adds agentic power.

  • Unlimited inline tab completions on every plan
  • AI chat that understands your full codebase
  • Cascade — multi-file agentic editing with a plan
  • Commands, previews, and one-click deploys
  • Support for VS Code, JetBrains, and browser use

Codeium vs GitHub Copilot vs Cursor

GitHub Copilot is the default choice for many teams thanks to its GitHub integration and JetBrains/Neovim coverage, with Pro at $10/month. Cursor is the premium agentic editor at $20/month. Windsurf undercuts Cursor at feature parity and has the most generous free tier of the three.

All three are strong; the real choice comes down to free-tier generosity (Windsurf), GitHub-native workflow (Copilot), or the most mature agentic editor experience (Cursor).

Frequently Asked Questions

Common questions about Codeium, answered.

Is Codeium free?

Yes. Codeium's free tier includes unlimited tab completions, AI chat, and commands — the most generous free plan among AI coding tools. Pro adds 500 credits per month of agentic usage for $20/month.

What happened to Codeium?

Codeium rebranded to Windsurf in late 2024 and grew from a completion extension into a full AI-first code editor with the Cascade agent. Existing Codeium accounts, extensions, and subscriptions carried over seamlessly.

How much does Windsurf (Codeium) cost in 2026?

Free tier is $0. Pro is $20/month, Max is $200/month for power users, and Teams is $40/user/month with admin controls. Annual billing and student discounts (around $10/month for Pro) can lower costs further.

Is Codeium better than GitHub Copilot?

Codeium/Windsurf offers a more generous free tier and agentic multi-file editing via Cascade. GitHub Copilot wins on native GitHub integration and starts at $10/month. For free and agentic coding, Windsurf is the stronger choice; for GitHub-first teams, Copilot is seamless.

Which IDEs does Windsurf support?

Windsurf works in its own AI-first editor built on VS Code, plus extensions for VS Code and JetBrains IDEs, covering the most common development environments.
