Here's a (my own) lightweight alternative, built using django & no javascript: https://gitlab.com/sodimel/share-links

It allows you to store links (title & language of the page, a pdf of the page, assign tags, to include them in collections), it has a very simple (moderated) comment system, set status of the link (online: direct link, offline: replace link by a webarchive one) a lightweight ui (remember: no js), multi-accounts (permissions), translations, some rudimentary stats and some other things (access a random page!).

See my own instance for an example with thousands of links: https://links.l3m.in/
