"...rather for web scraping. I applied to YC with this around 9 times"

There actually was a YC company that did exactly this several years ago. http://www.kimonolabs.com/

Sort of but not exactly, because IIRC they used a downloadable client. I wanted something that could run anywhere easily, hence the browser client. I used KL a few times, and followed their story, and found it interesting they moved to Tokyo. At the time I considered Import.IO, KL, Connotate, Mozenda and DiffBot to be the main competitors. My main idea as a point of difference was to be able to share the structure you've mapped on web apps, and share the action sequences as things others can use, so everyone gets a network effect benefit from the work of everyone else.

Thanks for posting. I don't think I knew they were YC, and did not know they were acquired by Palantir. That's interesting, and good news. Means the market is growing.

This looks cool! We use the DevTools protocol for a few things like our mobile emulation and screenshotting. Happy to chat - my email's todd at reflect.run
