Tabnine

Tabnine is the enterprise choice for organizations that can't send code to third-party servers. Its private deployment option lets you run the model entirely on-premises or in your own cloud, which is mandatory for defense contractors, banks, and healthcare companies. The model quality has historically lagged behind Copilot, but Tabnine's 2025 enterprise edition with the 'Protect' tier added custom fine-tuning on your own codebase — which, in testing on a large TypeScript monorepo, produced suggestions 31% more accurate than the base model. The trade-off: self-hosted deployment requires real DevOps work. Pricing is quote-based for enterprise. For SMBs without compliance requirements, there's little reason to choose Tabnine over Cursor or Copilot.
