O3 Code 2.0 is in open beta. Enable it under Settings → Experimental #3748 — it's a 2-way door, and your v1 workspaces and sessions stay put when you flip back.

Settings → Experimental — Try O3 Code v2 toggle and v1 → v2 migration

Remote workspaces

Every workspace in 2.0 is a cloud workspace. Point your local app at any O3 Code device on the same network — a beefier box across the room, a cloud VM, a teammate's host — and run workspaces on it as if they were local. Terminal, file editor, and chat all behave the same way #3566 #3606, and ports running on the remote surface in your sidebar so your local browser can hit them #3676.

Reimagined diff view

The diff viewer is rebuilt to feel like reviewing a PR on your machine — one infinite-scroll diff with a compact sidebar of changed files, per-file viewed state #3715 #3776, and shift/cmd-click selection across the file list #3683.

O3 Code CLI

The o3-code CLI is a single static binary that drives the same backend as the desktop app. Sign in with o3-code auth login, then create workspaces, tail terminals, and trigger automations from your shell or CI #3638 #3640.

A real IDE shell

Tab → Split → Pane with drag-and-drop everywhere — drop panes onto the tab strip to spawn tabs #3809. File tree with git decorations, file editor, a browser pane that keeps state across switches, a fresh terminal (XTerm.js + WebGL, kitty keyboard, OSC links, search), and Electric collections with optimistic updates #3722 — all in one window.

Migration in place

1.x projects and workspaces port directly into 2.0 #3670. The migration is org-idempotent #3775 #3781 #3783, and the migration modal only shows on first onboard #3816.
