NucleusIf Conductor is a conductor, Nucleus is the orchestra.
Same Claude Code and Codex on the subs you already pay, in parallel git worktrees — plus 50+ other models, auto review on commit, whole-repo security audit, image and 3D in the codebase, and Slack / GitHub / Sentry / cron triggers. Conductor sharpens the coding step. Nucleus runs everything around it — a self-improving codebase on one $20 bill.
Nucleus runs Claude Code, Codex, and 50+ other models in parallel worktrees — with auto review on commit, whole-repo security audit, in-repo image/video/3D, and Slack/GitHub/Sentry/cron triggers — for $20. Conductor runs parallel Claude Code + Codex on Mac, and stops there.
Same bill. Whole stack.
One bill. Four reasons.
The asset lands in the repo. Not in another app.
Conductor is a supervisor — it watches Claude Code and Codex work. Asking for a marble Atlas GLB means: leave Conductor, open Midjourney/Studio, generate, download, drop into `public/models/`, wire into the Three.js scene, refresh. Nucleus calls Studio inside the agent shell, drops the file into the right folder, and wires it into the right file. The agent that wrote the code generated the asset. Same thread.
Both free to start. Only one is the whole stack.
Conductor and Nucleus both let you run Claude Code and Codex on the subs you already pay — free to start, BYOK, no inference markup. The wedge is what else you need to ship. Conductor stops at orchestration; you still need a reviewer (CodeRabbit), a SAST scanner (Snyk), and an asset generator (Midjourney). The Conductor stack starts at ~$103/mo and balloons into the $1,000s with seat counts. Nucleus Plus is $20 and bundles all of it — review, security, image / video / 3D, automations, Agents chat — on one line item.
AI ships 10× faster. And 10× more vulnerabilities.
AI codegen has us shipping 10× faster — and quietly producing 10× more vulnerabilities. Conductor's review surface is whatever Claude Code surfaces in its own thread — no diff guard, no whole-repo audit, no inline catch as you write. Nucleus adds three layers — PR review, multi-stage security review, plus an in-app review as you write.
Parallel worktrees are one feature. The rest is the IDE around them.
Conductor's wedge is side-by-side worktree supervision. But the moment you want a PR opened from a Sentry spike, a security pass on Monday cron, or a coding run kicked off by a Slack message, you leave Conductor. Nucleus wires events to outcomes — Slack, Telegram, WhatsApp, GitHub, Sentry, cron — and the result lands in one inbox. Parallel-agent supervision is one panel inside the editor, not a separate app you alt-tab into.
One Subscription. Self Improving Codebase.
Who switches, honestly.
Stay on Conductor if side-by-side parallel Claude Code + Codex on auto-named worktrees is the entire job, and a metered Anthropic / OpenAI bill alongside CodeRabbit / Snyk / Midjourney is the stack you want.
Switch to Nucleus if
- you want Atlas, Claude Code, and Codex on the subs you already pay
- PR review at the diff before the commit
- the whole repo audited for security
- image, video, and 3D landing in the codebase, not a separate tab
- events — Slack, Sentry, cron — that fire agents and land outputs in one inbox
- one bill instead of four
Nucleus runs 50+ models across 10+ providers, so when Claude or OpenAI rate-limits or a new frontier ships, the workflow stays inside the same subscription.
Having the full stack in one place, compounds.
