Seriously I admire Joel, he is all over the internet everyday for 2 years now marketing his product. Browserless technically is a big nothing burger pretending to be a SaaS, it's written as open but it is not open source. You can't even use it commercially even it if it's self hosted https://github.com/browserless/chrome#licensing. This is a rare case of a successful rudimentary fake FOSS project that makes real money. Real BOSS!
EDIT: Why the hate, Joel? I've been following your success over the past year and I sincerely admire it even though it's outright parasite-tier big nothing burger of a project, but who cares 10 or 20 years from now, you got the money!
EDIT2: Okay Joel, I really get it you hate me, but you've to understand that it's one my favorite hobbies in my free time is to track online indie parasites like you and I've been following your excessive self-promotion on HN, Reddit, IndiHackers for a long time now. I don't know why, but it's just a hobby.
