Tabby is built for teams and individuals who want Copilot-style completion and chat but can't or won't send code to a third-party API, whether for compliance reasons or simple preference. It runs entirely self-hosted, supports consumer-grade GPUs for inference, and works with open code models rather than requiring a connection to a commercial model provider.
It integrates with VS Code, JetBrains IDEs, and Vim, and covers the standard set of features: inline completion, chat, and codebase-aware context. Being open source under an Apache-style license means the whole stack, from the inference server to the IDE plugins, is auditable, which matters more to Tabby's audience than it does for most Copilot users.
It's free and self-hosted by design, trading the convenience of a managed cloud service for complete control over where code and completions happen, a trade-off that resonates specifically with security-conscious teams and individual developers who prioritize data control over the latest frontier model.
