Anthropic's 'Epitaxy' Turns Claude Code Into a Dev Superapp

Anthropic is testing Epitaxy, a major overhaul of Claude Code that moves it from a single-session terminal tool to a full power-user environment. The new layout borrows from Cowork — Anthropic's desktop automation shell — and introduces dedicated panels for Plan, Tasks, Terminal, and Preview, all in one window.

Biggest unlock: multi-repository support. Developers can now work across multiple repos simultaneously, something that's been a hard limit of the current setup. There's also a Coordinator Mode in the works, where Claude acts as an orchestrator — delegating implementation tasks to parallel sub-agents while it handles high-level planning.

Hotkeys, tighter diff views, and a Cowork-adjacent UI round out what's shaping up to be a direct answer to OpenAI's Codex Superapp push. Both companies are reportedly targeting a release window in the coming days.

Why it matters: This isn't a UI refresh — it's Anthropic repositioning Claude Code as an agentic dev platform capable of running complex, multi-repo workflows autonomously.
