Hi fellow nerds. Linklever is a local and offline browser launcher. If you're often copy-pasting URLs between browsers, then Linklever might be for you.

It registers as your system's default browser. In the app, you configure rules and filters. Later, when you click a link outside of a browser, the rules determine which browser Linklever sends the link to. The filters transform the URL before sending it to the browser. For routing links between browsers, there are Firefox and Chrome extensions.

Browser launchers are no new concept; AlternativeTo lists 17 others, but so far Linklever is the only one that supports macOS, Windows, and Linux. It's also pretty darn fast, being AOT compiled. Launch latency is typically 10-20ms, which is unbelievable for .NET. Tech stack: C#, Avalonia, SQLite.

I'm also the author of the open source app BrowseRouter, whose moderate star count on GitHub was the inspiration to make Linklever.

I'm following a business bootstrapping stair-step method. This is my second product. I started working on it in Dec 2024 and launched it officially in July. I've made five sales so far, which has been a lot of fun.

I'm open to your feedback. Thanks for reading.
