One place for your coding agents, fused from the desktops you already use, your phone, and any machine you host yourself.
An agent's whole life is one process in one terminal on one machine. Close the laptop and it stops. Lose the disk and its work is gone. Run several and they collide.
Nucleic is what's been missing underneath them: a place where agents persist beyond any one machine, are backed up as they work, run on whichever host suits them best, and are watched the whole time. You stay in command.
The technology everything else in Nucleic stands on. It doesn't live on one machine — it lives on all of them, as one: your desktops, your phone, and any machine you host yourself each holding part of the whole. There is no home machine to lose.
Nothing important was ever in only one place. Close a laptop, lose a disk, walk out of range — Hydrangea heals around the gap and the session carries on elsewhere.
Side by side or continents apart, your devices find the fastest private route to each other on their own. When nothing else reaches, a zero-config relay carries ciphertext — and only ciphertext.
Every session's full story — conversation, changes, even uncommitted work — mirrored the moment it's made, under your keys, on machines you own.
Agents work sealed off from the machine in front of you — and when a job needs more, Nucleic summons more: a full Linux machine, an entire Mac, even eyes and hands on a real screen.
Every job gets the smallest world that fits it — a disposable sandbox by default, a real Linux machine when it needs a kernel of its own, an entire Mac when it needs Xcode. Thrown away when the job is done.
On a Mac or Linux desktop of their own, agents launch the app they just built, click through it, and check that it actually looks right before they call it done.
Put a repository under Nucleic's control and it earns clearance for work you'd otherwise babysit: branches merged in order, releases cut and shipped — because every command is witnessed as it happens. Facts, not inferences.
Isolation, attention, and trust — the three hard parts of running a fleet. Solved by design.
Agents ask. You decide. Every gated command and edit pauses for a risk-classified prompt — allow, deny, or modify-and-allow. First to answer, desktop or phone, wins.
Every session gets its own worktree and branch, and finished work merges itself — queued, conflict-aware, never mid-task. Or share one live trunk, with edits serialized per file so conflicts are structurally impossible.
⌘T captures a thought without breaking stride. Ideas queue in an inbox you can dispatch as a full agent run — one click, when the fleet has room.
One capable agent conducts; a fleet of workers plays in parallel. Frontier-grade thoroughness, at a fraction of the cost.
The cockpit, in your pocket. Watch sessions, answer approvals, and steer work from wherever you are — 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.
Nucleic is in open beta on macOS 27. Windows and Linux desktop builds are in active development.
