tom_doerr · x · 2026-09-18
simslim, an open-source Go tool from MobAI-App (1.9k GitHub stars), lets a single Mac run more iOS simulators by disabling background daemons each simulator doesn't need.
It ships as CLI and GUI, installs via Homebrew, and includes disk cleanup, device-set management, config profiles, and reboot-safe persistence — useful for local CI or large-scale parallel UI testing.
