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-ctl interface.

• Per-tab rendering engine selection and configurable default engine.
• Vertical tabs, spaces, groups, shared history, and site settings.
• Touch ID locks for spaces.
• Content blocking, per-site settings, routing rules, and pinned-tab previews across both engines.
• Command palette with plain-language commands.
• CLI control of tabs, spaces, navigation, page content, and screenshots.
• Chromium installation through Settings → Engines; in-app updates.
