Tabnine - Github Copilot alternative

Tabnine is an AI code assistant that accelerates and simplifies software development while keeping code private, secure, and compliant. It provides real-time code completions and an IDE chat feature powered by proprietary AI models trained exclusively on permissive open-source code. Solo developers benefit from local model options, zero data retention policies, and flexible deployment choices including fully air-gapped installations. Tabnine serves as a Github Copilot alternative with stronger privacy guarantees and enterprise customization capabilities.

Strengths

Fully private deployment options available on SaaS or self-hosted environments including VPC and on-premises with full air-gap capability.
Code completions use the Tabnine Universal model which is both private and protected, ensuring no code exposure.
Extensive IDE support including VS Code, all JetBrains IDEs (PyCharm, WebStorm, IntelliJ, Android Studio, GoLand, CLion, Rider, DataGrip, RustRover, RubyMine, DataSpell, Aqua), Eclipse, and Visual Studio 2022.
Advanced Context Engine with unlimited codebase connections for Bitbucket, GitHub, GitLab, and Perforce P4 (Helix Core).
Enterprise plans allow on-premises or VPC deployment ensuring full control over data and infrastructure while complying with enterprise data security policies.
Enterprise admins can connect Tabnine to internal LLM endpoints, integrating company private models accessible directly within the IDE.

Weaknesses

Basic and Pro users only access universal models while Enterprise customers get fine-tuned AI models trained on their codebase.
Advanced features like custom model integration and air-gapped deployment require Enterprise tier subscription.
Context window creation and chat RAG index computation occur on Tabnine servers (even in private installations) as local computation would stress user machines.
Third-party chat models available in Pro tier may have different privacy policies than Tabnine's protected models.

Best for

Developers and organizations prioritizing code privacy, requiring self-hosted deployments, needing compliance with strict data security policies, or wanting customizable AI models integrated with internal codebases.

Pricing plans

Basic — Free — Limited code completions, registered users only, universal models access.

Enterprise (SaaS) — Starts at $39 per user per month — Team management, advanced context engine, Jira integration, custom code validation rules.
Enterprise (Private Installation) — Custom pricing — Self-hosted deployment, air-gapped options, fine-tuned models, unlimited codebase connections, custom model endpoints.

Tech details

Type: AI code completion assistant with IDE chat capabilities
IDEs: VS Code (1.85-1.103), JetBrains IDEs (2023.2-2025.2) including PyCharm, WebStorm, PhpStorm, Android Studio, GoLand, CLion, Rider, DataGrip, RustRover, RubyMine, DataSpell, Aqua; Eclipse (4.28-4.36), Visual Studio 2022 (17.10-17.14).
Key features: Real-time code completions, IDE-integrated chat, code explanation, test generation, code fixing, documentation generation, repository context awareness, custom code validation rules (Enterprise).
Privacy / hosting: SaaS deployment or fully private self-hosted installations on VPC (AWS, GCP, Azure) or on-premises with optional air-gapped configuration. No code stored or sent to data plane; user identifiers always masked.
Models / context window: Universal models trained on public permissive open-source code; fine-tuned models available for Enterprise with customer codebase training. Chat supports Claude 4 Sonnet, Claude 3.7 Sonnet, Claude 3.5 Sonnet, GPT-4.1, GPT-4o, Gemini 2.0/2.5 Flash/Pro, Llama 3.1, Mistral 7B, Gemma-3, Qwen2.5 via private endpoints. Context window size not publicly specified.

When to choose this over Github Copilot

You require self-hosted deployment with full data control, including on-premises or VPC installations that can be completely air-gapped from external networks.
Your organization needs to integrate custom AI models, including third-party providers, open source models, or internally developed models with custom validation rules.
Maximum code privacy is essential, as Tabnine's completions use protected universal models with no code storage and masked user identifiers.

When Github Copilot may be a better fit

You prefer GitHub-native integration and want seamless workflow with GitHub repositories without additional configuration.
You need advanced personalization features immediately, as Tabnine's fine-tuned models customized to your codebase are only available in Enterprise tier.
Budget constraints favor simpler pricing models, as Tabnine's advanced privacy and self-hosting features require higher-tier subscriptions.

Conclusion

Tabnine differentiates itself as a Github Copilot alternative through its strong emphasis on privacy and deployment flexibility. The platform provides both SaaS and private installation options, with the latter supporting VPC or on-premises deployment on Kubernetes clusters. Organizations with strict compliance requirements or those wanting complete control over their AI infrastructure will find Tabnine's self-hosted capabilities particularly valuable. The trade-off is that advanced features like fine-tuned models and custom integrations require Enterprise-level investment, making it potentially overkill for individual developers seeking basic code completion.

FAQ

Q: Can Tabnine run completely offline without internet access?

A: Yes. Tabnine Enterprise supports fully air-gapped private installations that can operate on-premises without external network connectivity. This deployment option provides complete isolation while maintaining full functionality.

Q: What AI models does Tabnine use for code completions?

A: Tabnine code completions use the Universal model trained exclusively on permissive open-source code. Enterprise customers can also deploy fine-tuned models trained on their internal codebase. Chat features support multiple model providers including Claude, GPT, Gemini, and Llama variants.

Q: Does Tabnine store or train on my private code?

A: No code is stored or sent to Tabnine's data plane, and user identifiers are always masked. Code is used only during inference requests to create context windows for accurate suggestions, and for creating chat RAG indices computed on server GPUs.

Q: How does Tabnine compare to Github Copilot on privacy?

A: Tabnine offers self-hosted private installations on VPC or on-premises infrastructure with optional air-gapping, giving organizations complete control over where code is processed. This provides stronger privacy guarantees than cloud-only solutions.

Q: Which programming languages and IDEs does Tabnine support?

A: Tabnine fully supports VS Code, all major JetBrains IDEs (PyCharm, WebStorm, IntelliJ, Android Studio, GoLand, CLion, Rider, DataGrip, RustRover, RubyMine, DataSpell, Aqua), Eclipse, and Visual Studio 2022. It works with all major programming languages including JavaScript, Python, TypeScript, PHP, C/C++, Go, Java, Ruby, Rust, and more.

Q: What's the difference between Tabnine Basic, Pro, and Enterprise plans?

A: Basic and Pro users access universal models only, while Enterprise customers get fine-tuned AI models customized to their codebase. Enterprise adds fully private deployment options, unlimited codebase connections, Jira integration, custom AI validation rules, and model flexibility to use third-party or internal models.
