Temporal is an open-source durable execution engine for long-running, fault-tolerant workflows. For AI agents it provides automatic retry with backoff for LLM rate limits, Signals for human-in-the-loop steps, and guaranteed state persistence across server restarts or crashes.

• Durable workflow execution — survives crashes and restarts
• Automatic retry policies with exponential backoff for LLM calls
• Signals and Queries for human-in-the-loop interactions
• Child Workflows and parallel Activities for multi-agent pipelines
• Self-host or use Temporal Cloud (managed service)
