If you need mission-critical reliability for long-running AI agents that survive crashes, pick Temporal — its durable execution and human-in-the-loop signals are unmatched. If you want a permission-controlled autonomous assistant that runs 24/7 from chat or CLI for coding and task automation, Mercury Agent's 40+ hardened tools and multi-channel access make it the better choice. Choose based on whether you prioritize fault tolerance or autonomy with guardrails.
