I think if you look at no-code tools like Zapier, they do a great job empowering business users with most simple use cases like moving data from one app (ie facebook ads) to another (ie google sheets). But if you want to build a really advanced use case, like Amazon's support routing, for example, then Zapier will be able to get you 50% of the way there very quickly, but the remaining 50% basically becomes impossible.
We built Workflows for developers and see it as an alternative to writing cron jobs from scratch. While you can definitely write some code in Zapier, Workflows focuses on putting SQL and JS front and center when you need it, GUI when you don't.
If you give Workflows a try, I'd love to hear your feedback (jamie@retool.com)
