Arc rebuilt the chrome — sidebar, spaces, command bar. Egg rebuilds the browser plus the agent that lives inside it. If you loved Arc’s vertical tabs and got left behind when The Browser Company pivoted to Dia, this is for you.

The Browser Company shifted focus from Arc to Dia. If you don’t want to migrate to a brand-new product still in beta, Egg is a stable alternative.
Sidebar layout, drag-reorder, color groups. Same shape, different polish.
Egg’s browser profiles are full identity sandboxes — further than Arc’s spaces, which only separate tabs and bookmarks.
Skills, tools, browser automation, model choice. Arc Max was scoped narrower.
Tracker blocking and parameter stripping always on. No account required.
Egg ships changes weekly. Arc is in maintenance.
Arc’s Easels (collaborative web canvases), Boosts (per-site CSS overrides), and the iOS Arc Search app aren’t in Egg today.
