They're not easily comparable (I tried using Cloudflare Workers before going back to AWS). Lambda@Edge runs Node or Python. Cloudflare Workers runs V8 with "worker isolates" which has a few more caveats, an imperfect but improving dev experience, and doesn't work with a lot of npm packages.

What would be really useful for my use case (running browser tests on a schedule) is if Cloudflare workers actually supported running full headless chromium automation in addition to just V8 isolates. Right now I'm using puppeteer/playwright + Lambda, but would love to have more options.

Headless browser tests seem to be quite far away from the problems cloudflare workers are trying to solve.

Workers aren't the same as lambdas, they are a super slim JS environments. At 50ms max runtime most browsers won't even start, let alone fetch and process a page.

CloudWatch Synthetics may fit your usecase? https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitori...

Then there are more specialized browser-testing providers like LambdaTest.com and BrowserStack.com

and the venerable WPT (private instances, not the free public one at webpagetest.org)

I wished Google Cloud supported something similar Lambda@edge but I think my only alternative is Cloudflare Workers at the moment.
