Free AI autocomplete and chat across many editors and languages
Codeium offers AI code completion and chat through extensions for a long list of editors, with a free tier that has been unusually generous for individual developers. It autocompletes in dozens of languages, answers questions in a side chat, and can generate tests, explain or refactor selected code. The company behind it now also ships Windsurf, a full AI-native editor, and the same underlying model stack powers both. The differentiator is breadth of editor support combined with a free individual plan, which made it a common first step for developers who did not want to pay per seat.

The individual tier has been free, and team and enterprise plans are sold separately for administration and security features. Pricing and plan names have changed over time, so check the current terms before standardising on it.
The same company develops both. Codeium provides extensions that plug into your existing editor, while Windsurf is a standalone AI-native editor that goes further into agentic workflows using the same model stack.
There are settings controlling whether snippets are used to improve models, and enterprise plans add stronger guarantees. Read the current policy rather than assuming defaults, especially on proprietary code.
