# Recipe: sync vs async clients

Recipe — sync vs async client. Pointer to the SDK async\_workflow sample.

Both `Stratix` and `AsyncStratix` cover the entire resource surface — every method has a sync and an async form on the same name.

Canonical samples:

* [`samples/core/async_workflow.py`](https://github.com/layerlens/stratix-python/blob/main/samples/core/async_workflow.py) — concurrent operations with `AsyncStratix`
* [`samples/core/async_results.py`](https://github.com/layerlens/stratix-python/blob/main/samples/core/async_results.py) — fetch results from multiple concurrent evaluations

## When to use which

* **Sync (`Stratix`)** — scripts, CI gates, small batches, anywhere blocking is fine
* **Async (`AsyncStratix`)** — webservers, concurrent evaluation runs, throughput matters
