Aider vs Google Jules, side by side
FieldAiderGoogle Jules
TierBB Shutting down 31 Dec 2026

Google is winding Jules down: sessions are allowed until 11 Nov 2026, then it is read-only, and it shuts down on 31 Dec 2026. Source

Why this tierIt is mature and transparent, with git-aware clean commits. It is less autonomous than newer agents, which is why it sits at B-tier.It 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.
Best for
  • Clean, git-aware commits
  • People who want a mature, transparent terminal pair programmer
  • Small async tasks for free, while it still runs (sessions until 11 Nov 2026)
  • Trying a cloud agent without paying
Skip if
  • You want a highly autonomous agent
  • You don't work in the terminal
  • 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
