GitHub Copilot is hosted autocomplete in the editor. Open-source replacements are either a self-hosted model server or an editor agent that brings its own models.
Tabby is the self-hosted assistant. Cody and Roo attach models to the repo. Claude Code is an agent, not a GitHub Copilot ghost-text clone. This directory currently lists 10 mapped tools, led by Claude Code (112.6k GitHub stars).

| 9 | Cody-public-snapshot Cody is an advanced AI code assistant that leverages intelligent search and deep codebase context to help developers write, refactor, and fix code more efficiently. With AI-powered suggestions and context-aware capabilities, Cody accelerates development and helps reduce boilerplate and errors. | 3.8k | TypeScript | Apache License 2.0 |
| 10 | Shotgun A Spec Driven Development tool for writing codebase-aware specs that guide AI coding agents and prevent them from derailing. Enables automated, high-precision code generation and testing workflows with AI. | 711 | Python | MIT License |
Star rank is useful for adoption, not for picking a job. Use the diffs below to match the slice of GitHub Copilot you actually need.
Self-hosted autocomplete
Inline suggestions on machines you control. Closest Copilot-shaped server in this catalog.
Repo-aware chat
Sourcegraph Cody answers from the codebase. Use it for chat and edits, not only ghost text.

Tabby if you want self-hosted autocomplete. Cody if you want repo-aware chat. Roo or Claude Code if you want an agent instead of ghost text.
Tabby is designed to be self-hosted. Other tools here often call a model you already run or buy.
The clients and servers listed here are open source. Model weights and GPU time are separate costs.
