Tabby

What is Tabby?

Tabby is an open-source, self-hosted AI coding assistant positioned as a privacy-first alternative to cloud assistants like GitHub Copilot.

It is a full-stack solution: a Rust-based server hosts the models, exposes a web UI for chat and repository search, and ships plugins for editors including VS Code and JetBrains.

Tabby is self-contained and does not require a separate database or external cloud service, and it can run on consumer-grade GPUs, which makes on-premises deployment practical for teams that need their code to stay inside their own infrastructure.

Beyond inline code completion, it provides a chat interface and repository-aware retrieval so suggestions reflect the team's actual codebase, and it can be fine-tuned on private repositories. For organizations it adds enterprise features such as team management, usage analytics, and single sign-on.

Tabby is aimed at teams and individual developers with data-residency, compliance, or air-gap requirements, as well as anyone who prefers open-source, self-hostable tooling over managed SaaS. Strengths include full self-hosting, no required external dependencies, modest hardware needs, and editor integrations.

Trade-offs include that running and maintaining your own inference server takes effort, that completion quality depends on the chosen open models and available hardware, and that out-of-the-box capability may trail the largest proprietary assistants.

For organizations whose primary requirement is keeping source code off third-party servers, those trade-offs are usually acceptable, and Tabby gives them a credible, actively developed path to private AI assistance without sending code to an external vendor. Pricing changes often, so check the official site for current plans.
