# Nucleic — mission control for a fleet of coding agents
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. Work from your iPhone, too.

Built for macOS 27

## Agents got fast. You became the bottleneck.

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.

What it does

## Built for running agents in parallel, safely.

Isolation, attention, and trust — the three hard parts of a fleet, each solved by design.

01

### Autoship

Finished work merges itself — queued per branch, conflict-aware, never mid-task. On Nucleic Control projects.

02

### Nucleic Control

Nucleic clones and sandboxes your repo and watches git directly, so agents stay contained and unattended work runs where Nucleic is in command.

03

### nvrsionBeta

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.

04

### Orchestra

Grant standing consent and one agent spins up its own parallel subagents — maximum thoroughness, no wall of prompts.

05

### Work from your iPhone

The cockpit, projected to your pocket — watch sessions, answer approvals, send input, and steer work from your iPhone, end-to-end encrypted.

06

### Agent-agnostic

Claude Code, Codex, and Grok Build behind one approval flow — plus any agent that speaks ACP, the open Agent Client Protocol.

Built on virtualization

## Real machines, summoned on demand.

When an agent needs a safe place to work, Nucleic conjures a real machine for it — a genuine computer running right on your Mac, walled off from everything else. The agent can install, run, and break whatever it likes inside, and your Mac never feels a thing. When the work is done, the machine simply disappears.

### A real place to work

Not a flimsy wrapper — a genuine machine, with real walls around it. An agent gets room to work exactly as it would on its own computer, while your Mac stays completely untouched.

### A whole Mac in a window

For work that needs a real Mac — building an app, clicking through a live interface — Nucleic hands an agent an entire macOS to itself, right there on screen for you to watch it work.

### Fresh every time, gone when done

Machines appear the moment they're needed and vanish the moment they're not — clean on every run, with no leftover state, nothing to reset, and nothing left behind.

Native to Apple platforms

## A first-class citizen on Apple platforms.

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.

### On-device intelligence

Apple Intelligence runs local tasks — classifying turns, summarizing tool calls, auto-triaging your idea inbox — privately, right on your Mac.

### Native sandboxing

Sandboxed agents run in real, lightweight VMs — natively, with no extra daemons.

### macOS orchestration

Give an agent a whole Mac of its own. Nucleic spins up an isolated macOS VM where it clicks, types, and runs apps — never touching your host machine.

How your devices connect

## One fleet, wherever your devices are.

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.

### Local network

On the same Wi‑Fi, devices find each other over Bonjour and connect directly.

### Tailnet

Apart, they meet over your own Tailscale tailnet.

### Nucleic Private Relay

A zero-config fallback for when neither device can reach the other. End-to-end encrypted.
