⬅️ Show HN: Obelisk – a WASM-based deterministic workflow engine

SvenL 9 daysReload

One issue I had many time with workflow engines was updates. I have a workflow and it has already running instances. 2 scenarios:

Can I update the workflow while it has running instances without interfering the running instances?

Can I update a running instance with a new version of the workflow to patch some flaw? If no, can I replay an updated version of a workflow with the log of an old workflow version?

This is a pretty cool idea but I'm trying to think of the advantage of WASM vs other execution engines.

It seems to me one of the main use-cases for WASM is to execute lambdas, which are often short-lived (like 500ms timeout limits). Maybe this could have a place in embedded systems?

I believe https://flawless.dev/ is another implementation with a very similar technology stack. I'd love to know how you compare and what the key differences are!

Really nice project. What’s the reasoning behind the AGPL licensing. My understanding is that it will hurt adoption unless you’re planning to offer paid licensing options? Either way it’s a really nice project and I’m keen to try it out. I’ve found it tricky to get a WASM/WASI setup where I can at least my http requests (probably my own skill issue).

I have a similar idea but for audio effect and music production:

For workflow, how do you think of async in wit at this moment?
