Free AI website builder that runs offline: agent + local model + WordPress

A free AI website builder that runs offline means the whole loop — the agent, the model, and the site it’s building — lives on your machine, with no account, no API key, and no internet required. ReDock is a free native macOS app that does this: a built-in agent, a local-LLM catalog sized to your Mac’s RAM, and a full local site platform that provisions real WordPress, Astro, Next.js, and more. You describe a site; a model on your own hardware builds it.

What “offline” actually requires

Most “AI website builders” are cloud services. The AI runs on their servers, your site lives in their hosting, and nothing works without a connection and a subscription. Offline means the opposite: every piece runs locally.

Three parts have to be local for that to hold:

The model. ReDock’s catalog runs models on-device, tiered to your Mac’s RAM, with no API keys. Inference happens on your hardware.
The agent. The built-in agent turns your request into tool calls without a cloud brain in the loop.
The site. WordPress (PHP pinned per site, MySQL, install in one step), headless WP, Astro, Next.js, Node, Bun, and PHP all run locally on real https://name.test domains.

With all three on your machine, you can build a site on a plane. Nothing phones home.

How the agent builds a site

You describe what you want. The agent reads the site’s state, picks the right tools, and builds — then reads the result back to confirm it worked. For WordPress that means creating the site, authoring pages from the theme’s real Gutenberg block patterns, installing plugins, and logging you in through a single-use magic link. The correctness rests on ReDock’s MCP tools, which execute and verify each change, so a modest local model is enough to drive the build.

Because it’s patterns-first, the output is real, editable Gutenberg blocks — not an HTML blob. You can open the editor and adjust anything by hand. The detail is in AI edits your WordPress site: patterns-first authoring explained and WordPress MCP: let Claude build, edit, and manage WordPress for you.

Free, and honest about the ceiling

ReDock is free, and local models cost nothing to run — no key, no meter. That’s the “free” part, and it’s real.

The honest part: a model sized to your Mac’s RAM won’t match a large cloud model at the hardest reasoning. For building a site out of structured tasks — create page, insert pattern, activate plugin — that’s fine, because the tools carry the load. For a task that needs deep reasoning you might connect a cloud model instead, which ReDock also supports. Local LLM on 8GB Macs and Claude vs local models for agent work lay out the tradeoffs without spin.

What driving it looks like

Offline, you open ReDock and pick a local model from the catalog. You tell the built-in agent: “Build a WordPress site for a coffee shop — home, menu, and contact pages.” It creates the site, composes each page from block patterns, installs a contact-form plugin, and hands you a magic login link. You open wp-admin, review, and tweak. No internet touched, no key entered, nothing billed. When you’re back online and ready, ReDock’s one-click Cloudflare deploy and custom domains take it live. The first-site guide walks through provisioning, and the built-in agent docs cover the local model side.

FAQ

Does it really work with no internet?

The build loop does — the model, the agent, and the site all run on your Mac. You only need a connection when you deliberately share or deploy the finished site.

Is it actually free?

Yes. ReDock is free, and local models run on-device with no API key and no per-token cost. It’s a native macOS app (macOS 12+); Windows isn’t supported.

What kinds of sites can it build?

WordPress and headless WordPress, plus Astro, Next.js, Node, Bun, and PHP with MySQL. See the stacks docs for the full list of supported runtimes.
