LinkAce is a self-hosted archive to collect links of your favourite websites. Save articles to read them later, tools to use them in your next project, or historic content to archive it for the long term. LinkAce comes with a lot of features while keeping a clean and minimal interface.
All saved links are monitored. Get a notification when a website moves or becomes unavailable. Links are backed up via the Internet Archive after you saved them. Choose tags to categorize links, add them to custom lists to group them by a topic or occasion.
Your link archive can be accessed by guests, or kept private. Links, tags and lists can be set private separately. Both private and public links are accessible via RSS feeds. Feeds are also available for tags and lists.
It will import from a browser's bookmarks, and export to a browser, but it does not integrate with any browser bookmark systems. So it is a stand-alone solution. However, if you use different browsers this may be an interesting solution, or you like to share categories of links with others, or just keep track of links without having a bunch of dead links (most browser bookmarks don't check validity of links).
Their site also has a demo you can try out. If you're looking more for a Read It Later service though, Wallabag is probably more suited to that, although you could label a category as 'Read Later' and use it for that.
