Cool project! I’ll check it out.

Regarding userscripting, from the F.A.Q.:

Why use an external automation tool (Playwright) instead of a browser extension?

While Beachpatrol allows to control the browser from both the OS and from a browser extension, our priority was the OS. Therefore, something like Playwright was the natural choice.

Furthermore, while controlling the browser from an extensions is possible, Manifest v3 removed the ability to execute third-party strings of code. Popular automation extensions like Greasemonkey and Tampermonkey could also be affected by Manifest v3. The alternative is to embed the code into the extension, but that would requires re-bundling the extensions after every change. Other tricks do exist to make this approach work, and there is some hope for future Manifest v3 solutions, but this path is certainly tricky.

It is more likely that Selenium and related tools will continue to work in the foreseeable future given the business demand for traditional browser testing.

This sounds a lot like Selenium

It’s based on Puppeteer which has been around awhile. It’s pretty useful for automating UI tests.

Unlike a password manager that just logs you in, Beachpatrol can run any automation task, like checking your email, downloading files, or filling out forms. You have to create Playwright scripts for these tasks and run them from a shell command. There is an example script already in the commands folder, which you can run with the command beackmsg smoke-test. The sky is the limit, basically.
