Tabnine

Tabnine is one of the oldest AI code assistants (2019) and has pivoted hard into the enterprise segment. Its selling points are air-gapped / self-hosted deployment, per-customer model fine-tuning on your code, and strict data controls — no training on your code, optional VPC hosting, SOC 2. For teams where Copilot's cloud dependency is a non-starter, Tabnine is often the default.

Frequently asked questions

Does Tabnine train on my code?

No — their base models are trained only on permissively licensed code, and customer code is never used for training. Optional per-tenant fine-tuning on your repos is opt-in and stays within your tenant.

Can it fully replace Copilot?

For completion and chat in mainstream languages, yes. Copilot's agentic features (Workspace, Copilot Coding Agent) currently have a richer feature set; Tabnine's own agent is catching up in 2026.
