Run a fleet of
coding agents.
Stay in command.

Nucleic runs Claude Code, Codex, and Grok Build — or any ACP-compatible agent — in parallel, each sealed in its own git worktree, with one Mac cockpit to watch, approve, and merge their work.

Pre-1.0 · early access by request · your code never leaves your machine

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. Ten agents, one repo, zero collisions — each reviewed and merged on its own.

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.

Worktree isolation

Every session works in its own git worktree and branch. Concurrent agents physically can't touch each other's files.

Three agents — or any ACP agent

Claude Code, Codex, and Grok Build behind one approval flow — plus any agent that speaks ACP, the open Agent Client Protocol. Pick one per task; review them the same.

Real approvals

Every command and edit pauses for a true yes/no — risk-aware, first responder wins. On your Mac, or your phone.

Orchestra ✦ fan-out

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

Autoship

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

nvrsionBeta

Shared-trunk versioning for agents: one tree, per-file locks, each edit lands as its own commit. No branch juggling.

Local-first · end-to-end encrypted phone link · sandboxed agents on Nucleic Control · nothing uploaded to run
