Overview
Temporal is a durable workflow engine for building reliable distributed systems. Write workflows in Go, Java, Python, or TypeScript. Handles retries, timeouts, and state automatically.
Pros
- Durable execution — workflows survive crashes
- Write workflows in real languages
- Built-in retry policies and timeouts
- Strong consistency guarantees
- Excellent observability (Web UI)
- Battle-tested at scale (Uber, Netflix)
Cons
- Complex to self-host (Cassandra/MySQL + Elasticsearch)
- Steep learning curve
- Cloud pricing is significant
- Overkill for simple workflows
- Heavy runtime footprint
Verdict
Temporal is the most reliable way to build workflows that must not fail. The durable execution model — where workflow state survives process crashes, server restarts, and network failures — eliminates an entire class of distributed systems bugs. If your system has workflows that span minutes, hours, or days and must complete reliably, Temporal is the infrastructure to build on.
