Yup, I've tried dozens of tools in this category, and here are some of the main differentiators:

- Ease of use: Most existing tools have pretty clunky UX and are hard to get started on

- Reliability: I've had issues with many tools simply not working, especially when it comes to more complex sites

- Cloud: Browserflow lets you deploy your flows to the cloud to run them on a schedule whereas many tools are local-only

Hope that helps!
