Developer who wants a free async coding agent

Jules' free tier of 15 tasks/day is the most generous of any async agent. No credit card, no subscription — connect your GitHub repo and start assigning tasks immediately.

Reviewing and approving AI-generated implementation plans

Unlike agents that jump straight to code, Jules shows you its plan first. You can redirect it before a line is written — useful for complex features where the approach matters as much as the output.

Automating CI/CD pipelines with GitHub Actions

Jules has native GitHub Actions support, letting you trigger agent tasks automatically — run Jules on every failing test, or trigger it when a new issue is labeled.

Google ecosystem developer who wants a native AI agent

If you're already in Google's stack (GCP, Firebase, Workspace), Jules integrates naturally and benefits from Gemini's Search grounding for GCP-specific context.
