About Tabnine

Tabnine is the privacy-first AI code assistant, delivering completions, chat, and agents inside your IDE while deploying SaaS, VPC, on-premises, or fully air-gapped with zero code retention. Once a freemium favorite, it went enterprise-only in 2025: the Code Assistant platform is $39/user/month and the Agentic Platform $59/user/month, both billed annually, with a 14-day trial. In July 2026 Tabnine was acquired by testing giant Tricentis.

Pros

Only major AI assistant that runs fully air-gapped on your own hardware
Zero data retention — customer code is never stored or used for training
IP-safe: models trained on permissively licensed code with indemnification
Category pioneer — shipped deep-learning completions two years before GitHub Copilot

Cons

No free plan since April 2025, and the old $9–12 Dev plan is gone too
$39/user/month is roughly 4x GitHub Copilot's $10 Pro plan
Only annual billing is published — month-to-month means talking to sales
Raw completion quality trails Cursor and Copilot's frontier-model output

Our verdict

Best for: Regulated enterprises — banks, defense, healthcare — whose code cannot leave their own infrastructure.

Skip if: You're an individual or small team; GitHub Copilot at $10/month or Cursor delivers more capability for far less.

Our review

Tabnine invented this category — its 2019 Deep TabNine model beat GitHub Copilot to market by two years — and then chose a different war. While rivals raced frontier models, Tabnine bet on the one thing hyperscalers can't easily offer: your code never leaving your building. Fully air-gapped deployment, zero retention, models trained only on permissively licensed code, and IP indemnification make it the assistant a bank's security team can actually approve. For defense contractors, healthcare systems, and anyone with a hostile compliance checklist, there is genuinely no comparable alternative.

The cost of that focus is everything else. Completion and chat quality sit a clear tier below Cursor and Copilot, which ride the newest frontier models. The pricing turn is harsher still: the free tier died in April 2025, the $9–12 Dev plan followed, and entry now means $39/user/month billed annually — about 4x Copilot Pro. Hobbyists and startups have simply been shown the door, and the G2 profile (4.1) reflects a product loved for its guarantees more than its output.

The July 2026 acquisition by Tricentis adds uncertainty: the Context Engine is being folded into a software-testing platform, and while Tabnine continues as a product, roadmap priorities may tilt toward quality engineering rather than everyday coding.

Verdict: the definitive pick when code privacy is a hard requirement, and hard to justify otherwise. If your compliance team would wave through Copilot or Cursor, buy one of those instead.

What reviewers elsewhere say

72% positive — Reviewers value the privacy guarantees, on-prem deployment, and enterprise controls; criticism targets completion quality versus Copilot and Cursor, and the loss of free and individual plans.

Frequently asked questions

What is Tabnine?

Tabnine is an enterprise AI code assistant offering completions, chat, and agents inside major IDEs, distinguished by privacy-first deployment: it can run SaaS, in your VPC, on-premises, or fully air-gapped, with zero code retention.

How much does Tabnine cost?

The Code Assistant platform is $39/user/month and the Agentic Platform is $59/user/month, both billed annually, with a 14-day free trial. There is no free plan — Tabnine retired its free tier and individual Dev plan in 2025.

Is Tabnine really private?

Yes — that's its core pitch. Code is never stored or used for model training (zero retention), deployments can be fully air-gapped so nothing leaves your network, and the company holds SOC 2, GDPR, and ISO 27001 compliance.

Does Tabnine have an API?

No public API. Tabnine is consumed through its IDE plugins and, on the Agentic Platform, a CLI — not programmatic endpoints.

Tabnine vs GitHub Copilot — which should I choose?

Choose Tabnine when data control is non-negotiable: air-gapped deployment, zero retention, and IP indemnification. Choose GitHub Copilot for better raw capability at a quarter of the price ($10/month) if standard cloud privacy terms are acceptable.

Who owns Tabnine now?

Tricentis, the enterprise software-testing company, announced its acquisition of Tabnine on July 30, 2026. Tabnine's Context Engine is being integrated into Tricentis' agentic quality engineering platform.
