One thing that has surprised me is that no one has tried to standardize on the Zapier or IFTTT APIs / SDK implementation to allow for faster deployment of integrations. Seems like there could be a movement here that is akin to how many services use S3 compatible APIs.
Pipedream (which is probably Automatisch main competitor) also has a repo full of integrations: https://github.com/PipedreamHQ/pipedream. Their format is a bit more specific than Windmill.
Hopefully, we all agree on a format and differentiate ourselves on the quality of the orchestration, flow capabilities, performance etc ...
There is an argument (that I agree with) that the AGPL (used by this project) is not a free software license either, for similar reasons, but this does not seem to have consensus yet.
