Tabnine
Privacy-first AI code completion that runs locally or on your own cloud
What is Tabnine?
Tabnine is one of the oldest AI code completion tools, predating GitHub Copilot by several years. Originally built around smaller, locally-running models, it has evolved into a full AI coding assistant with chat, inline completions, and enterprise deployment options. The defining characteristic that sets Tabnine apart is its focus on privacy and compliance — enterprise customers can run the entire Tabnine stack on-premises or in their own private cloud, ensuring that code never leaves the company's infrastructure.
Beyond privacy, Tabnine has invested heavily in personalization. Its models can be trained on a team's private codebase, learning the specific patterns, naming conventions, and architectural decisions that characterize a given organization's code. This results in suggestions that feel noticeably more relevant than generic completions — a meaningful advantage for teams with large, mature codebases that have established conventions over years of development.
Tabnine integrates with all major IDEs including VS Code, IntelliJ, Eclipse, and Visual Studio. The chat assistant supports code explanation, refactoring, test generation, and documentation writing. The free plan offers basic completions with a local model, while the Pro plan unlocks the full cloud model with whole-line and full-function completions. Enterprise pricing is custom and includes dedicated support, compliance documentation, and SLA guarantees that are relevant for regulated industries like finance and healthcare.
