Linklever is a desktop app which you can set as your default browser. When you click a link, it opens a real browser. Which browser opens depends on rules you set.
You can also launch links from the address bar in the app. This works even if Linklever is not the default browser.
Linklever scans your system for all installed browsers and browser profiles. In the app, you configure "rules" - which URLs open in which browser. When you click a link, Linklever opens the matching browser. There is always a "catch-all" rule - the browser that opens if there are no other matches.
