Why this tierIt is a free async agent for small tasks. For most builders it is not a daily driver, so it sits at B-tier. Google is winding Jules down and it shuts down on 31 Dec 2026, so the B-tier only holds while it still runs.Its spec-driven approach turns specs into tasks, which keeps bigger vibe-coded projects on the rails. That structure makes it an A-tier pick for larger builds.
Best for
  • Small async tasks for free, while it still runs (sessions until 11 Nov 2026)
  • Trying a cloud agent without paying
  • Bigger vibe-coded projects that need structure
  • Working from specs that turn into tasks
Skip if
  • You need a tool you can rely on past 31 Dec 2026
  • You need a daily-driver agent
  • You want hands-on, step-by-step control
  • You want a quick one-off fix rather than a spec-driven flow
  • You want an open-source agent where you choose the model
