What is Temporal?

Temporal is a durable execution platform that enables developers to build resilient, fault-tolerant applications where the full running state of a workflow is durable and recoverable by default. The platform persists application state with built-in retries, task queues, signals, and timers to ensure code always picks up where it left off after any interruption. Temporal allows developers to code for durable execution using SDKs in Go, Java, TypeScript, Python, and .NET, enabling polyglot workflow deployments. The platform provides comprehensive visibility with the ability to inspect, replay, and rewind every workflow execution step by step. Adopted by hundreds of thousands of global developers, including thousands of independent AI projects and major AI labs, Temporal has become the industry standard for building mission-critical applications that require guaranteed execution and complete observability.

Strengths and tradeoffs

What this tool does well, and the limitations to keep in mind.
