Tabby

Tabby (TabbyML) is an open-source AI coding assistant designed to bring AI into your development workflow — on your terms. Unlike proprietary cloud assistants, Tabby is self-hostable, so you can run it on-premises or on your own hardware and keep your code private. It offers code completion, an in-IDE answer engine, and inline chat across major editors. For developers and teams that want capable AI coding help without sending code to a third party, Tabby is a compelling, transparent choice.

What is Tabby?

Tabby is an open-source AI coding assistant designed to bring the power of AI to your development workflow as a self-hosted alternative to proprietary assistants. Its features include AI-powered code completion that predicts your next coding move, an answer engine providing in-IDE answers to coding questions without context switching, inline chat for real-time AI conversation within your editor, and data connectors for contextual assistance from external sources. It emphasizes privacy-conscious, secure, flexible, and transparent AI coding, with deployment flexibility across cloud IDEs, on-premises, and even consumer-grade GPUs, and no mandatory external databases or cloud dependencies. Tabby supports major IDEs including VS Code, IntelliJ, Neovim, and PyCharm, and works with leading models. It offers community (open-source, free), team, and enterprise plans, and is actively developed (with newer features and model partnerships).

What it does well

• Open-source and self-hosted: run it on your own hardware.
• Private: keep code in-house, no mandatory cloud.
• Full assistant: completion, answer engine, and inline chat.
• Broad IDE support: VS Code, IntelliJ, Neovim, and more.

Who it is for

Tabby fits developers and engineering teams — especially privacy- and security-conscious ones — who want a capable AI coding assistant they can self-host on-premises or on their own hardware, keeping code private and avoiding vendor lock-in. Its open-source nature and IDE breadth suit teams that value control and transparency. Solo developers who just want a zero-setup cloud assistant may prefer hosted tools, and self-hosting requires some setup and hardware, but for private, self-hostable AI coding, Tabby is a compelling, free-to-start choice.

Things to keep in mind

• Self-hosting requires some setup and suitable hardware (a GPU helps).
• AI-generated code still requires review and testing.
• Team and enterprise features are paid beyond the open-source core.

Our verdict

Tabby is a compelling open-source AI coding assistant, and its self-hosted, privacy-first design is its defining strength: run it on-premises or on your own hardware, keep your code in-house, and avoid mandatory cloud dependencies, while getting code completion, an in-IDE answer engine, and inline chat across VS Code, IntelliJ, Neovim, and more. For privacy- and security-conscious developers and teams, that control is exactly the point. Self-hosting takes some setup and AI code needs review, but for private, self-hostable AI coding, Tabby is an excellent, free-to-start choice.
