GitHub Agent HQ brings third-party coding agents — from partners across the ecosystem — into GitHub alongside GitHub Copilot, with a 'mission control' surface to assign, run, and track agents across GitHub.com, VS Code, and the CLI. For teams already living in GitHub and paying for Copilot, it is a low-friction way to delegate work to agents without leaving the platform. (Agent HQ is rolling out through paid Copilot plans — check GitHub for current availability and which agents are supported.)
Fleet takes a self-hosted approach. It is a single Go binary you run on your own machine or server that launches Claude Code agents in defined roles, watches GitHub labels via the gh CLI, and drives the dev-review-release chain through its Fabric event bus — with run-time budgets, agent evaluation, and a risk model governing the team. Fleet integrates with GitHub but does not run inside GitHub's cloud.
