AWS compatibility¶

Stegflow exposes an AWS-compatible API: 32 actions with Signature v4 auth. Point the official AWS SDK or CLI at a Stegflow endpoint and it just works.

• Use the official AWS SDKs & CLI. Just change the endpoint URL.
• Your existing activity workers connect unchanged, with the same GetActivityTask / SendTaskSuccess.
• Run your existing ASL definitions with no rewrite.

To set up credentials and point a client at your instance, see Connect an AWS SDK or CLI.

Known differences¶

Areas where Stegflow does not yet match AWS behavior:

• Variables inside intrinsic functions. AWS lets you reference Assign variables in an intrinsic function's arguments (for example States.Format('Hello {}', $customer.name)); Stegflow does not resolve variables there yet. Inside an intrinsic, $… paths read the state input and $$… the context object. See Intrinsic functions.
• Distributed Map. Only the inline Map state is available. Distributed Map (ProcessorConfig with "Mode": "DISTRIBUTED" and its EXPRESS child executions) is not implemented, so the map-run actions listed above return an explicit not-implemented error.
