The short version
Tabnine is an AI code completion assistant that lives inside your IDE — VS Code, JetBrains, Eclipse, Visual Studio, Vim, Sublime, and more — suggesting lines and blocks of code as you type. The free Starter plan includes basic AI completions with no credit card required. Full completions, AI chat, code generation, and agents need the Dev plan at $12 per user per month. Tabnine’s defining trait is privacy: it never trains on your code.
What Tabnine does
Tabnine suggests code inline as you type — single lines, whole blocks, and function bodies — in more than 600 programming languages. It learns your coding patterns, and its models train only on permissively licensed code — less risk of copylefted suggestions. The standout is the privacy posture: zero data retention, your code never stored or used for training, and on Enterprise tiers the whole stack can run on your own infrastructure, fully air-gapped. That makes it the default choice in regulated industries — finance, healthcare, defense — where sending source code to a third-party cloud is a non-starter.
What is free vs. what costs money
Free (Starter):
- Basic AI code completions as you type
- Support for all major IDEs (VS Code, JetBrains, Eclipse, Visual Studio, Vim, Sublime, Neovim, and more)
- Community support
- No credit card required
Dev ($12/user/month): full AI completions, AI chat inside the IDE, code and test generation, AI agents, and team features.
Enterprise (custom pricing): self-hosted, VPC, or air-gapped deployment, SSO and admin controls, custom model training on your own codebase, and usage analytics.
The honest limitations
The free completions are basic — the best models, AI chat, and code generation sit behind the paywall, so the free tier is a taste, not the full product. On raw suggestion quality, independent comparisons rank GitHub Copilot ahead on complex or novel code; Tabnine is strongest on routine patterns. It is primarily autocomplete-and-chat, not an autonomous coding agent — agentic multi-file refactoring is limited. And Dev at $12 a month costs slightly more than Copilot Pro ($10) for less raw capability — you are paying for privacy.
Who Tabnine is best for
- Developers in regulated industries: finance, healthcare, defense — anywhere code legally cannot leave the network.
- Teams with strict IP policies: zero data retention and permissively licensed training data keep legal happy.
- Privacy-minded individuals: AI assistance without your code ever being used for training.
- Not for: individuals who want maximum free capability (Copilot’s free tier is more generous), or developers who want agentic, multi-file coding workflows.
Pros and cons
Pros:
- Free Starter plan, no credit card needed
- Never trains on your code — zero data retention on every plan
- Trained on permissively licensed code, reducing IP risk
- Broadest IDE support: 15+ editors including Eclipse and Visual Studio
- Self-hosted and air-gapped options for enterprises
Cons:
- Free completions are basic; chat and best models are paywalled
- Weaker than GitHub Copilot on complex or novel code
- Limited agentic coding features
- Dev plan ($12) costs more than Copilot Pro ($10)
FAQ
Is Tabnine free?
Yes — Starter is free with basic completions across 15+ IDEs, no credit card required. Full completions, chat, and agents need Dev ($12/user/month).
Does Tabnine train on my code?
No — Tabnine never trains on your code and retains zero data. Enterprise plans can run the entire stack on your own infrastructure.
Tabnine vs. GitHub Copilot free — which is better?
It depends on your priority. Copilot’s free tier is more generous on raw capability (2,000 completions a month) and stronger on complex code. Tabnine wins on privacy, by a wide margin. Pick capability or pick privacy.
Which IDEs does Tabnine support?
VS Code, JetBrains IDEs, Eclipse, Visual Studio, Vim, Neovim, Sublime Text, and more — over 15 editors, including some Copilot doesn’t cover.
