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.
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.
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.
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.
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.
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.
Apple Intelligence runs local tasks — classifying turns, summarizing tool calls, auto-triaging your idea inbox — privately, right on your Mac.
Sandboxed agents run in real, lightweight VMs — natively, with no extra daemons.
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.

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.
