Self-hosted AI coding assistant

TabbyML/tabby

Maintained by TabbyML

Tabby is an open-source, self-hosted AI coding assistant positioned as an on-premises alternative to GitHub Copilot. The TabbyML team also builds Pochi, a linked agent project that turns GitHub issues into tasks and creates PRs.

Pros & cons

Each point cites its sources and says what kind of evidence backs it. A second reviewer tried to refute every claim before it was kept.

Pros

  • DocsA self-hosted Copilot alternative with code completion, codebase chat, and team features (SSO, access control).[1][2]
  • User reportsRuns on your own GPU or Apple Silicon, so code never leaves your infrastructure.[1][2]
  • DocsPlugins for VS Code, Vim/Neovim and IntelliJ, plus GitHub/GitLab integration.[1]
  • MetadataA mature project (since 2023) with about 34k stars.[1]

Cons

  • MetadataDevelopment has slowed: the last release (v0.32.0) was Jan 2026 and the last push June 2026, while the team's news now centres on Pochi.[1][2]
  • MetadataNot fully Apache: the ee/ directory is under a separate enterprise licence.[1]
  • User reportsA user reports unstaged git changes being randomly reverted while Tabby runs.[1]
  • User reportsRepo-context bugs with GitLab subgroups and Bitbucket, and Vulkan builds failing to launch on Fedora.[1][2][3]
  • User reportsLocal model quality and speed depend on hardware; small models are weak at conversational coding.[1][2]
Best for
Teams that need an on-prem, air-gapped code completion and chat server.
Watch out for
Maintenance has slowed and enterprise features are under the ee licence; it is a completion tool, not an agent harness.
