Finicky is a macOS application that allows you to set up rules that decide which browser is opened for every url. With Finicky as your default browser, you can tell it to open Bluesky or Reddit in one browser, and LinkedIn or Google Meet in another.

Route any URL to your preferred browser with powerful matching rules
Automatically edit URLs before opening them (e.g., force HTTPS, remove tracking parameters)
Write rules in JavaScript or TypeScript for complete control
Create complex routing logic with regular expressions and custom functions
Handle multiple browsers and apps with a single configuration
Keep your workflow organized by separating work and personal browsing

      match: "x.com/*",
      url: (url) => {
        url.host = "xcancel.com";
        return url;
      },
    },
  ],
  handlers: [
    {
      // Open all bsky.app urls in Firefox
      match: "bsky.app/*",
      browser: "Firefox",
    },
    {
      // Open google.com and *.google.com urls in Google Chrome
      match: [
        "google.com/*", // match google.com urls
        "*.google.com*", // also match google.com subdomains
      ],
      browser: "Google Chrome",
    },
