GitHub Copilot

GitHub's AI pair programmer with a coding agent, CLI and cloud agent.

Official site: github.com Free tier: Yes Open source: No Platforms: IDE, CLI, Web
Last verified: Oct 15, 2026 Last tested: Not yet, hands-on test pending
⚠ Preliminary, based on public research, hands-on test pending. These scores come from a desk review of public sources (official pricing pages, docs, changelogs), linked on each tool page. Rex hasn't run the hands-on tests yet, so tiers shown are projected. Under our rubric, a tool's official tier is capped at B until it's tested.

What looks good

  • Cheapest paid entry point here ($10/mo) with unlimited code completions
  • Native to GitHub: assign issues to the cloud coding agent
  • Works across VS Code, JetBrains, CLI and more

Watch-outs

  • Moved to usage-based AI credits on Jun 1, 2026, so heavy agent use costs more
  • Agent, chat and CLI usage all draw from the same credit pool
