Tabnine

Description

Tabnine offers AI code completion with a strong emphasis on privacy, including options to run models on-premises or in a private VPC for regulated teams.

What it does & solves

Tabnine solves the data-privacy objection that stops some regulated companies (finance, healthcare, defense, government contractors) from adopting AI coding tools at all. Instead of sending code to a shared third-party cloud model, teams can run Tabnine's models on-premises or in their own private cloud, and the tool can be trained specifically on a company's own codebase for more relevant suggestions without that code leaving their infrastructure. That trade-off means it's less about being the flashiest agentic coder and more about being an AI assistant that a compliance team will actually approve.

Use cases

• Getting inline code completions across a wide range of IDEs (VS Code, JetBrains, and more)
• Running AI code assistance fully on-premises or in a private VPC for compliance-sensitive teams
• Training suggestions on a company's own private codebase for more relevant completions
• Using chat-based code explanation and generation without sending code to a public model
• Standardizing AI coding tools across a regulated engineering org under one privacy policy
• Generating unit tests and documentation from existing code
• Reviewing AI-flagged code for basic quality issues before a human review

Who it's for

Best suited to developers and engineering teams in regulated or security-conscious industries where sending code to a third-party cloud model is a blocker — finance, healthcare, government, and similar sectors. Individual developers without those constraints will likely find newer agentic tools more capable for the price; Tabnine's strongest privacy features (on-prem/VPC deployment, private training) are Enterprise-tier only.

Getting started

1. 1Start a free trial (currently around 90 days) rather than expecting a permanent free plan — Tabnine discontinued its free tier in 2025.
2. 2Install the Tabnine extension for your IDE (VS Code, JetBrains, and others are supported).
3. 3Connect it to your codebase if you want suggestions trained on your own code and patterns.
4. 4Use inline completions as you type, and chat for larger explanations or generation tasks.
5. 5If privacy/compliance is the deciding factor, talk to sales about on-premises or private-VPC deployment before the trial ends.

Tips for using it well

• If privacy compliance isn't a requirement for you, compare suggestion quality against newer agentic tools before committing — that's where Tabnine tends to trail.
• Use the 90-day trial to test whether on-prem or private-VPC deployment fits your infrastructure before signing an annual contract.
• Train Tabnine on your own codebase early — its main edge over generic completion tools is relevance to your existing patterns and libraries.
• Check which IDE integrations you actually need before buying; coverage is broad but depth varies by editor.
• For a compliance-driven purchase, loop in security/legal early since the privacy-relevant features and pricing sit in the custom Enterprise tier.

Plans & pricing

Free plan: No permanent free plan — Tabnine dropped its free tier in 2025. New users get a roughly 90-day free trial of the paid product, which requires payment details to start.
