Nucleic runs Claude Code, Codex, and Grok Build — or any ACP-compatible agent — in parallel, each isolated and observed down to the edit, with one Mac cockpit to watch, approve, and merge their work.
One agent per terminal means you babysit one task at a time. Run several by hand and they collide — same files, same branch, same working dir.
Nucleic gives every session its own real git worktree and branch. Infinite agents, zero collisions — each reviewed and merged, automatically.

Isolation, attention, and trust — the three hard parts of a fleet, each solved by design.
Finished work merges itself — queued per branch, conflict-aware, never mid-task. On Nucleic Control projects.
Nucleic clones and sandboxes your repo and watches git directly, so agents stay contained and unattended work runs where Nucleic is in command.
Version control purpose-built for agentic coding. Many agents commit to one shared trunk in real time — no branches to juggle, so shipping keeps pace with the work.
Grant standing consent and one agent spins up its own parallel subagents — maximum thoroughness, no wall of prompts.
The cockpit, projected to your pocket — watch sessions, answer approvals, send input, and steer work from your iPhone, end-to-end encrypted.
Meet the iPhone app →Claude Code, Codex, and Grok Build behind one approval flow — plus any agent that speaks ACP, the open Agent Client Protocol.
No Electron. No web wrapper. Nucleic is a real Mac app — 100% Swift and SwiftUI — with a native iPhone remote alongside it. It looks, feels, and performs like it belongs on your machine.
Built in Swift 6.4 and SwiftUI, top to bottom — so it runs featherweight: minimal CPU, memory, and battery, even with a full fleet of agents going.
Apple Intelligence runs local tasks — classifying turns, summarizing tool calls, auto-triaging your idea inbox — privately, right on your Mac.
Sandboxed agents run in Apple's containerization framework — real, lightweight VMs, with no extra daemons.

Every device running Nucleic finds the fastest path to the rest — the local network when they're side by side, your private tailnet when they're apart, a relay when neither can reach the other. Today your iPhone reaches your Mac; the same fabric is growing into a full mesh, where any Nucleic node — Mac or iPhone — can discover and work with every other. Every path runs end-to-end encrypted.
On the same Wi‑Fi, devices find each other over Bonjour and connect directly.
Apart, they meet over your own Tailscale tailnet.
A zero-config fallback for when neither device can reach the other. End-to-end encrypted.
