Tabby
Self-hosted Copilot: an open-source coding assistant you run next to the repo so completions never leave the building — BYO models, IDE plugins, no seat tax to GitHub.
Product preview

Overview
Tabby is Copilot for shops that cannot send code to GitHub: a server next to the repo, IDE plugins that look familiar, models you choose. Continue and Cline are agent-shaped; Tabby is still mostly completions, which is what air-gapped teams often actually want on day one.
You will operate GPUs. Quality tracks the model you plug in, not a magic Tabby ranking. Compared with Copilot it is more work and more ownership. If the constraint is residency, that trade is the product.
Pros / Cons
Pros
- Completions never leave the building
- Familiar IDE plugins
- BYO models, Apache server
- No GitHub seat tax
Cons
- You run the GPUs
- Less agentic than Continue or Cline
- Quality is only as good as the plugged-in model
Who it's for
Air-gapped code completion
Replacing Copilot under a residency rule
IDE autocomplete against local weights
Shops that already operate GPU inference
Bottom line
Self-hosted Copilot — buy the ops, keep the code, skip GitHub's seat.
