David Heinemeier Hansson, using Claude Code, wrote omarchy-cmd-default-browser, which reads mimeapps.list files directly and resolves the default browser in about 10ms instead of the 72ms taken by xdg-settings due to its chain of POSIX shell scripts. The helper checks Hyprland-specific config first, falls back to xdg-settings and xdg-mime when nothing is configured, and is now used by omarchy-launch-browser and omarchy-launch-webapp. A separate optimization also cut Omarchy's status bar startup time from around 20 seconds to 15 seconds on a six-monitor setup with many widgets. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### why is xdg-settings get default-web-browser so slow to run It takes around 72 milliseconds per call because it chains through multiple entangled POSIX shell scripts to resolve the default browser. Omarchy addressed this by writing a lightweight replacement helper, omarchy-cmd-default-browser, that reads mimeapps.list files directly and completes the same lookup in about 10 milliseconds. _Developers tuning startup latency can track small shell-level fixes like this one on daily.dev._ ### how does omarchy-cmd-default-browser determine the default browser It reads the x-scheme-handler/http default from config-dir mimeapps.list files, the same way xdg-mime does, checking the desktop-specific hyprland-mimeapps.list first. It takes the first listed entry whose Exec command still resolves, skipping stale entries left behind for removed browsers. If nothing is set in a config dir, it falls back to xdg-settings, then BROWSER, then xdg-mime for https. _Anyone debugging mimeapps.list resolution order can reference details like these via daily.dev._ ### how much did Omarchy improve its status bar startup time A separate optimization reduced Omarchy's shell bar startup time from around 20 seconds down to about 15 seconds for a six-monitor setup with many widgets. This was addressed in a different pull request from the one that sped up default browser detection, as part of broader millisecond-level performance work in Omarchy 4.0.5. _Engineers chasing desktop shell startup regressions can follow fixes like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@lifehacknexus** · 1 upvotes > Crazy how a simple config lookup can be 7x faster than a standard utility 😂 Makes me wonder how many other Linux desktop operations have hidden overhead that we just accept as normal.
