Selfhosted

With a few other volunteers we are monitoring a list of websites for a local project. Every few days we manually go through all those links to check if new events were published on those websites. (We can not automate this task). I installed https://readeck.org/en/ on my server, but it isn't suited for our use case. I am looking for an opensource tool where everyone (without creating an account) can go to

• browse a list of url
• add new entries
• sort them in categories
• easily mark it as "visited on [curent date]"

I know i could just use a shared Ethercalc or any table tool but i would love a dedicated tool where the last clic by someone on a link is automatically monitored and update the last visit date. Also it would be great that when adding a new link, the tool would check if it isn't already in the database. Our goal is to simplify this collaborative task and avoid the time spent checking websites others have already checked a few days ago.

I hope some of you have any ideas
