An alternative for a code based workflow like Temporal are Dapr workflows (https://docs.dapr.io/developing-applications/building-blocks...), where you write a set of code based activities into a graph and these can have fan-in, fan-out, sequential patterns etc. Its all code in several supported languages and because Dapr also has building block APIs for pub/sub, service invocation, secrets as well as connecting to underlying infrastructure you can combine workflow with these APIs to build an overall solution.
