Linkwarden is a fully self-hostable, collaborative bookmark manager to collect, organize and archive webpages

looks cool, wonder how that compares to wallabag. Is there a mobile app as well?

Is making an account with their cloud service a requirement for self hosting?

Are pages compressed before storage? I can imagine storage would become an issue after a while.

I've been using xBrowserSync for a few years now and it works great. It's open source and you can find both their API, mobile app, browser extensions in their GirHub repo and you can self host.

I have Serverless implementation of xBrowserSync API in both AWS and Azure.
