Obelisk – a WASM-based deterministic workflow engine
A lightweight engine for durable execution / deterministic workflows I built with Rust, wasmtime and the WASM Component Model. Its main use is running reliable, long-running workflows that can automatically resume after failures. Looking for feedback on the approach and potential use cases!
In plain words
Obelisk is a workflow engine built with Rust and WebAssembly that executes long-running tasks reliably. It automatically resumes workflows if they fail, making it suitable for developers who need durable execution of complex processes. The engine uses the WASM Component Model to provide a lightweight, deterministic approach to workflow management, allowing tasks to recover from interruptions without losing progress.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
