Guide

Migrating from GitHub Copilot to open-source tools

A practical guide to migrating from GitHub Copilot to open-source AI coding tools, including Continue, Aider, OpenCode, and local model workflows.

Quick framework

  1. Identify which Copilot features your team actually uses daily.
  2. Map each feature to an open-source equivalent.
  3. Run a pilot with one tool on one project for a week.
  4. Collect feedback on completion quality, latency, and workflow fit.
  5. Roll out gradually — don't switch the whole team at once.
