// The shift
The work changed — agents write the code now. So we rebuilt the IDE from the ground up for it.
// Rebuilt from the ground up
Not features stapled onto a single-cursor editor — the whole surface is designed around running Claude, Codex, and DeepSeek side by side, and turning their parallel work into one shippable history.
Every tab is an agent session — Claude Code, Codex, or DeepSeek, your pick per tab. Run as many as your machine can handle. While one writes tests, another refactors, another writes docs. Each runs at its own pace; you only context-switch when something needs your attention.
Every tab gets its own git worktree on disk. No more stash, checkout, pop dance between switching tasks — five branches live side-by-side, each ready to ship.
Stack finished tabs into a queue and hit Ship. Harmonic merges them into your base branch in order, surfacing conflicts inline for review and opening PRs in one pass.
Connect your work, personal, and client GitHub accounts side by side. Each repo remembers which one to use — clone with the right credentials, push to the right remote, open PRs as the right identity. No SSH-key juggling.
Claude, Codex, or DeepSeek per tab — and within each, pick the model: Opus 4.7 for the hard stuff, Sonnet for bulk, Haiku for cheap experiments. Switch per tab, switch mid-conversation — spend on intelligence only where it pays off.
Command palette + keyboard-first. Switch tabs, open repos, ship work, run any action without reaching for the mouse — so the agents stay in flow and so do you.
