Tabnine

Tabnine is a privacy-focused coding assistant that can run entirely inside your own infrastructure. It is one of the oldest tools in the category and competes on control rather than on the largest model.

Capabilities

• Self-hosted deployment. Code never leaves your network in the on-premise configuration.
• Per-repository tuning. Models can be adapted to your own code style and internal libraries.
• Provenance filtering. Optional safeguards against suggestions matching public code with restrictive licences.
• IDE coverage. Works across the mainstream editors and IDEs.

Trade-offs

Raw completion quality trails the largest hosted models, and the strongest governance features sit behind enterprise pricing.

Best for

Regulated industries, defence and finance — anywhere code cannot be sent to a third-party service.
