Nexus
Nexus is the interface that sits between AI coding agents and the thing you’re building, and runs entirely on your Mac. Ask in plain words and watch your site change live. Every finished task is saved locally, and nothing goes out until you publish.
Use your existing Codex or Claude Code subscription, or connect your own LLMs locally to Nexus through Ollama. Nexus adds the visual development environment without another monthly bill or credit system. Nexus is a one-time purchase. No subscription. Buy it once and it’s yours.

One-time purchase. Lifetime updates.
Stop paying for another development environment that charges monthly fees and limits your work with credits when you already have your own AI coding agents.
Nexus is a native macOS integrated development environment that gives you a visual workspace for building with AI. Bring your existing Codex or Claude Code subscription, or connect your own LLMs locally to Nexus through Ollama. Nexus provides the interface, not the AI agents.
Your projects stay on your Mac, you decide when to publish, and Nexus never charges subscription fees or sells credits. Pay once, use it forever.
AI coding agents and any associated subscription or usage costs are separate from Nexus.
Nexus runs entirely on your Mac. Your code, your history and every change stay with you. The only services that ever see your project are the ones you choose to connect, like the AI plan that powers your agent, GitHub or Stripe. Use an offline local model instead, and nothing is sent to an AI company at all.
One payment, lifetime updates, no subscription and no credits to top up. There is no meter running and nothing to cancel. You bring the AI plan you already have, or use a local AI model on your own Mac, so you get your full money’s worth from it. One license covers up to two of your Macs at a time, and you can move it between them yourself.
Your project is plain files in a folder you own. Choose any framework, host or tool you like, and open it in any editor. You decide where your site lives, what it uses and when it goes public. Stop using Nexus tomorrow and your project keeps working, with nothing to export. Services you connect, like hosting, are yours: you pay them directly, on their own terms. That is how software should treat the people who pay for it.
A native Mac app, not a browser tab. Your keys are kept in the macOS Keychain, Apple’s secure, encrypted password storage. Dictation uses Apple’s own on-device speech recognition.
| Typical cloud AI builder | Nexus | |
|---|---|---|
| Where your code lives | On their servers | On your Mac |
| What you pay | Every month, plus credits used up with every change | Once, with lifetime updates |
| If you stop paying | Your project or site can stop with it | Nothing to stop paying: it’s a one-time purchase, so Nexus never stops working and you keep using it. (Services you connect, like hosting, bill you directly.) |
| Your tools and hosting | Locked into their ecosystem: their editor, their hosting, their database | Your choice. Any framework, any host, any database, and your own editor alongside |
| Branding on your project | Makes changes you didn’t ask for, like adding a “Made with” badge or their own favicon to your site | None. Your project carries only your brand |
| Who sees your project | The platform, and whoever it shares with | Only the services you connect |
| Your API keys | Stored in their cloud | In your Mac’s Keychain, or with the service that needs them. Never in a cloud of ours |
| Your voice | Basic voice-to-text, sent to a server | Apple’s premium on-device dictation |
Download Nexus and use it on your own Mac, with your own projects, before you buy. Nothing is locked or held back during the trial, so you can decide with the full app in front of you.
Bring your own AI plan or a local model.
Nexus provides the visual development environment, not the AI agents themselves. You’ll need your own Codex or Claude Code access, which may require a separate paid subscription, or you can connect your own LLMs locally to Nexus through Ollama. Nexus is a one-time purchase with no recurring fees or credit system.
Everything your project uses is installed and runs locally on your Mac. You install your AI agent (Codex, Claude Code, or your own LLMs through Ollama) and the tools your project is built with, such as Node.js for framework-based sites. Nexus runs them and shows you a live, visual view of your project as it changes. Plain HTML sites need nothing extra.
Every copy of Nexus starts with a 14-day free trial, so you can fully evaluate it on your own Mac before you buy. Once a purchase is made, it is final and non-refundable. See the Terms of Use.
