Codeium.
Multi-IDE assistant with strong free tier and enterprise deployment.
What it is.
Codeium's core IDE-extension product. Distinct from Windsurf (their agent IDE fork). Lives inside VS Code, JetBrains, Vim, Eclipse, Visual Studio, and a dozen others. The strongest free tier in the category and the most flexible self-hosted deployment.
Where it fits.
Buyers who cannot move off their existing IDE — JetBrains shops, Eclipse holdouts, regulated environments. Self-hosted Codeium is the assistant inside three of the four largest US defence contractors and a long list of European banks.
- Most generous free tier in the category
- Broadest IDE coverage outside Copilot
- Strongest self-hosted and air-gapped story
- Brand fragmentation between Codeium and Windsurf confuses buyers
- Agent surface narrower than Cursor or Windsurf
Frequently asked.
What is the difference between Codeium and Windsurf?
Codeium is the IDE extension. Windsurf is the agent IDE fork. Same company, separate products, separate deployment paths.
Is the free tier suitable for commercial use?
Yes. Commercial use permitted on individual free tier — the unusual move that built market share.
Can Codeium be deployed in air-gapped environments?
Yes. The self-hosted product runs without external network access. Standard deployment in classified environments.
