Refrax
Refrax lets each tab use WebKit or Chromium while keeping the same spaces, history and site settings. Its refrax-ctl CLI gives scripts and agents control of both engines; spaces can be locked with Touch ID.
Highlights
- Switch individual tabs between WebKit and Chromium while keeping shared browser state.
- Lock spaces with Touch ID and organize tabs into spaces and groups.
- Automate either engine through the same
refrax-ctlinterface.
