WASM-Powered Built on WebAssembly Component Model for interoperability, deterministic workflow execution, isolation and safety. Write workflows in real code instead of YAML. Supported structured concurrency simplifies error handling and cleanup. Crash resilient and replayable as every execution parameter, every step and the result is stored in the execution log. Controlled HTTP client with built-in limitations and tracing. Every execution parameter and result is stored in the execution log and retried on a timeout or a failure.
