GitHub's coding agent has an obvious advantage: it lives where issues, branches, pull requests, and reviews already live — assign it an issue (from GitHub, or from Jira through the tracker integration), it works on a GitHub Actions runner, and a pull request comes back. For organizations standardized on Copilot, that is the shortest path from issue to PR.
ProPR keeps the GitHub-native review experience and leaves agent choice open. A plan can start in ProPR, use Claude Code or Codex for one task, use Antigravity CLI for another, and still take fix requests through normal GitHub comments. The GitHub PR path remains the shared record when the agent changes.
ProPR fits when GitHub remains the collaboration surface while orchestration, provider choice, logs, and usage visibility live in your deployment. Agents run on your infrastructure with your existing subscriptions or API keys, so the model bill stays directly with your provider.
