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.
21 active of 21 chats across 4 projects.
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.
Claude Code, Codex, and Grok Build behind one approval flow — plus any agent that speaks ACP, the open Agent Client Protocol.
The cockpit, projected to your pocket — watch sessions, answer approvals, send input, and steer work from your iPhone, end-to-end encrypted.
Grant standing consent and one agent spins up its own parallel subagents — maximum thoroughness, no wall of prompts.
Every session works in its own git worktree and branch. Concurrent agents physically can't touch each other's files.
Version control purpose-built for agentic coding. Many agents commit to one shared trunk in real time — every edit landing instantly, no branches to juggle — so shipping keeps pace with how fast they work.
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.
