Choose Tabnine
Need local AI models for privacy compliance
Overview
Codeium and Tabnine are AI code completion tools that integrate into your IDE. Codeium, the company behind Windsurf, offers unlimited free completions plus chat and search features. Tabnine focuses on code privacy with an option to run models locally, keeping your code off external servers. Both support major IDEs including VS Code, JetBrains, and Neovim.
Privacy Considerations
Tabnine's local model option is its key differentiator for enterprise teams. Code never leaves your machine, which matters for organisations with strict data policies. Codeium processes code in the cloud, which enables more powerful completions but means your code passes through external servers. For open-source work and personal projects, this rarely matters. For enterprise code, it can be a deciding factor.
Frequently Asked Questions
Which has better free tier?
Codeium. It offers unlimited free completions and chat, while Tabnine's free plan provides only basic completions.
Can Tabnine run completely offline?
Yes. Tabnine offers local models that run on your machine without internet access, though completion quality is lower than cloud models.
Which has better completion quality?
For cloud-based completions, both are comparable. Codeium tends to have a slight edge in multi-line completions.
