DevIntern is a self-hosted automation worker that polls your issue tracker for ready tickets and uses your existing coding agent to implement them, opening pull requests for human review. It supports trackers like Jira, Linear, Trello, Asana, and GitHub Issues, and works with coding agents such as Claude Code, Codex, and Cursor. DevIntern handles the full loop including branch creation, optional self-review, and responding to review comments as commits. Interactive use is free forever, with a paid tier unlocking unattended background automation. All code, credentials, and diffs stay on your own machines and are never sent to DevIntern servers.
