Obviously tooting my own horn here, but these are some products:

- https://checklyhq.com - synthetic monitoring

- https://microlink.io - automation

- https://www.browserless.io - testing

- https://www.scrapingbee.com/ - scraping

All are business leveraging these types of frameworks

Thanks for the mention (browserless.io)! Really enjoying this site, let me know if you'd like a guest post and I'd happily add something. We've gathered a few weird tricks and tips as well. Definitely a lot that can be shared!

I don't like to have my home WiFi on all the time but I want to be able to activate / desactivate it from my phone anytime so I send a SMS to my RaspberryPi (running raspisms) that launches an app that connects to my ISP router box and activate the WiFi like I would do manually.

My app is powered by Selenium but the concept is the same.

I use Puppeteer at https://www.emailthis.me for scraping meaningful content from web pages and converting web pages to PDF.

I'm actually using it in building an in-house health-check platform for our sites.

Its purpose in our case is front-end performance measurement. In short, have a script running checks in a Cron Job, published to static reports we can reference over a timeline.

Nothing overly sophisticated, but it suits our current budget ($0).
