Tabnine

Tabnine has been in the AI code completion space longer than most competitors, offering a mature, reliable product with broad IDE support. The Free plan provides unlimited completions with a 400K index limit, while the Pro plan ($12/month) upgrades to an advanced model with 100MB index for larger projects.

Tabnine supports all major IDEs including VS Code, JetBrains, IntelliJ, Eclipse, and more. Its local-first approach in some configurations provides privacy advantages for enterprise users with sensitive codebases.

For developers who prioritize IDE compatibility and reliable code completion without requiring chat-based AI features, Tabnine offers a proven, cost-effective solution.
