This looks great. I'll have to play around with it.

Related, we built a developer oriented Zapier clone for event scale automations awhile back for our internal product. We've since pivoted and have been debating on potentially open sourcing the engine as well.

We built ours using Rust with a DSL for all the triggers, actions, and action inputs/outputs. The actions themselves are defined as APIs, which makes it easy to add functionality in any language. Most of our actions have been built in Typescript.

Is there interest from anyone in potentially using it?
