## When it is useful

Build Temporal workflows, activities, and workers (Python/TS/Go/Java/.NET/Ruby/Rust), CLI, non-determinism, signals/queries. Distinct from inngest-durable-functions and trigger-authoring-tasks.

## The Catch

Vendor lock + always-on-adjacent on any durable workflow. Local `temporal server start-dev` is not production. OSS self-host $0. Distinct from inngest-durable-functions / trigger-authoring-tasks.
