Nucleic Beta
Built for macOS 27

Run a fleet of
coding agents.
Stay in command.

Claude Code. Codex. Grok Build. Any agent that speaks ACP. Nucleic runs them all in parallel — each one sandboxed, every edit in view — with one Mac cockpit to watch, approve, and merge.

The agents aren't the bottleneck anymore. You are.

One agent per terminal means babysitting one task at a time. Run several by hand and they collide — same files, same branch, same working directory.

Nucleic gives every session its own real git worktree and branch. As many agents as you want, zero collisions — each one reviewed, merged, and shipped automatically.

The Nucleic cockpit — the Control panel open over a project's chats. Illustrative.Nucleic on iPhone — watch, steer, and ship from anywhere. Illustrative.
What it does

Parallel by design. Safe by default.

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

01

Autoship

Work that's done ships itself. Finished sessions merge automatically — queued per branch, conflict-aware, never mid-task. On Nucleic Control projects.

02

Nucleic Control

Your repo, cloned and sandboxed. Nucleic watches git directly, so agents stay contained — and unattended work runs on ground Nucleic commands.

03

Antimatter Mesh

Your Macs, cloud runners, and iPhones become one machine. A custom network layer stitches every device into a single surface — so an agent running anywhere feels like it's running right in your hands.

04

Orchestra

One frontier model conducts. A fleet of leaner workers plays in parallel — Fable 5 orchestrating, Sonnet 5 doing the heavy lifting. Frontier-grade thoroughness, at a fraction of the cost.

05

Work from your iPhone

The cockpit, in your pocket. Watch sessions, answer approvals, and steer work from wherever you are — 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 containers & virtual machines

The right machine for the job, summoned on demand.

When an agent needs somewhere safe to work, Nucleic summons the right machine — a container for the quick stuff, a real Linux box for real dev work, a whole Mac when only a Mac will do. Each one walled off from yours. Free to install, run, and break anything inside. Gone the moment the work is done.

Containers, for the quick stuff

A shell, a script, a one-off command. Nucleic drops it into a container that starts in an instant and vanishes just as fast. Real isolation, zero ceremony.

A real Linux machine

When the job calls for a genuine kernel, a desktop, or root, the agent gets a full Linux VM of its own — real hardware underneath, not a corner of yours.

A whole Mac of its own

For building an app or clicking through a live interface, the agent gets an entire macOS to itself — running under the hood, never touching the Mac in front of you.

Native to Apple platforms

Made for the Mac. Every pixel of it.

No Electron. No web wrapper. Nucleic is 100% Swift and SwiftUI, with a native iPhone remote at its side. It looks, feels, and performs like it was born on your Mac — because it was.

On-device intelligence

Apple Intelligence handles the local work — classifying turns, summarizing tool calls, triaging your idea inbox — privately, entirely on your Mac.

Native sandboxing

Agents run in real, lightweight virtual machines — native to macOS, no daemons, nothing extra to install.

macOS orchestration

Hand an agent a Mac of its own. Nucleic spins up an isolated macOS VM where it clicks, types, and runs apps — while yours stays untouched.

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 nothing else reaches. Today your iPhone reaches your Mac. Tomorrow, every Nucleic node — Mac or iPhone — discovers and works with every other. End-to-end encrypted, on every path.

Local network

On the same Wi‑Fi, devices discover each other over Bonjour and connect directly. No setup at all.

Tailnet

Farther apart, they meet over your own Tailscale tailnet — private, direct, yours.

Nucleic Private Relay

When nothing else connects, a zero-config relay does. End-to-end encrypted, always.

Nucleic is in open beta. All it asks is macOS 27 on Apple Silicon.
