Tabby is an open-source, self-hosted AI coding assistant - a privacy-first alternative to GitHub Copilot from TabbyML (Apache-2.0). You run the Tabby server yourself (Docker, a consumer-grade GPU, or your own cloud); there is no shared multi-tenant API and no external calls to third parties. The server exposes an OpenAPI-documented REST surface (Swagger UI at /swagger-ui, spec at /api-docs/openapi.json) for code completion, OpenAI-compatible chat completions, an Answer Engine backed by a doc-ingestion knowledge base, health, model registry, and telemetry events. Because it is self-hosted, the base URL is your own instance (default http://localhost:8080). TabbyML also offers hosted Team and Enterprise plans.
