How It Works

Three steps.
Zero terminal.

01

Download & install

Grab the free Windows app, set a password and a recovery email, and your dashboard opens right in your browser. Your PC just became a server — nothing to buy, no account on anyone's cloud.

02

Build your app

Use the built-in AI assistant to describe what you want in plain English. Or build in Claude, ChatGPT, or any AI tool you already use — then upload the files to your dashboard. Both ways work.

03

Share it with the world

Hit publish and your app gets a public URL instantly — no setup needed. Already own a domain? Connect it in a click and host it right from your machine.

Built-in AI assistant.
Or bring your own.

Baumeister has a built-in AI coding assistant — describe what you want and it builds it right on your machine. But you can also build apps in Claude.ai, ChatGPT, or any AI tool you already love, then upload and deploy them from your dashboard. Your hardware, your workflow.

Option A
Built-in Assistant
Chat directly on your server's dashboard. The AI reads your project files, writes code, and deploys — all in one place. No switching between tools.
Option B
Build Anywhere, Deploy Here
Already vibe-coding in Claude.ai, ChatGPT, or Cursor? Just upload the files to your Baumeister dashboard and hit publish. Your server runs anything.

Built for people who build things.

01 / 06

No coding required

Use the built-in AI assistant to describe what you want in plain English. Or build with Claude.ai, ChatGPT, or any AI tool — then upload and deploy. Either way, no coding skills needed.

02 / 06

Always yours

A private server for your projects or small business. Your sites are live whenever your PC is on — and come back up automatically with it. No shared servers, no data centers, no cloud accounts. Your data never leaves your machine.

03 / 06

On the internet in one click

Hit publish and your site is live at a real address with automatic HTTPS — share the link with anyone, on any device.

04 / 06

Hardware you already own

If it runs Windows, it's a server now — no new gear required. Want a dedicated, silent, always-on box instead? That's the Baumeister Kit, shipping July 2026.

05 / 06

Private by default

Your IP is never exposed. SSL is automatic. Your server is invisible to the public internet — only your apps are reachable.

06 / 06

No lock-in, ever

Your projects are plain files on your own disk, one click from a GitHub backup. Uninstall any time and keep everything. Nothing proprietary, nothing to trap you.

Cloudflare Tunnel

Optional. Free. For custom domains — no ports to open.

Custom Domains

Use any domain you own. Connect it in a click. HTTPS is automatic.

Local Dashboard

Runs on your machine — manage everything even without internet.

IP Hidden

Your home IP is never exposed to the public.

Questions & answers.

Do I need to know how to code?
Nope. You have two options: use the built-in AI assistant to describe what you want in plain English and it builds it for you, or use any AI tool you already know — like Claude.ai, ChatGPT, or Cursor — to create your app, then upload the files to your server and hit publish. Either way, no coding knowledge required.
How does the AI Assistant work?
It's a chat window built into your server's dashboard. You type what you want to build, and the AI reads your existing project files, writes new code, and deploys changes directly to your hardware. You can also build apps externally — in Claude.ai, ChatGPT, Cursor, or any tool you prefer — and simply upload the files to your Baumeister dashboard to deploy. For the built-in assistant, there are two options: connect your own API key (free — you pay your provider based on usage, with no request limits) or subscribe to Assistant Pro ($12.99/month for 300 standard + 10 premium requests, no API key needed).
What AI providers can I use?
With the free plan, you can use Claude (Anthropic), ChatGPT (OpenAI), Grok (xAI), or Gemini (Google) — your choice. Just paste your API key into the settings. You pay your provider directly based on usage, with no request limits on our end. With Assistant Pro, it's powered by Claude and fully managed for you — 300 standard and 10 premium requests per month.
Are there any monthly fees?
No required fees at all. The software is free and runs on the PC you already own — so your "hosting bill" is a few cents of electricity. Publishing, SSL, GitHub integration, and the AI assistant with your own key are all free. The only optional costs are a custom domain (~$10/year), Assistant Pro ($12.99/month for 300 standard + 10 premium requests) if you don't want to manage an API key, and the $349 hardware kit if you'd rather not keep your PC on.
Can people actually visit my apps from the internet?
Yes. When you publish, your app gets a public URL that anyone can visit — no configuration needed. For a custom domain like myapp.com, traffic is routed securely through a Cloudflare Tunnel, with your home IP hidden and HTTPS automatic.
Can I really host a website at home for free?
Yes — that's the whole idea. Baumeister is a self-hosted web server: your Windows PC does the hosting, publishing runs through a free secure tunnel, SSL is automatic, and you get free .baumeister.host addresses. The only thing you pay for is electricity you were already paying for.
Do I need a special internet connection?
No. Any standard home internet works — publishing runs through a secure Cloudflare Tunnel from your computer, so there's no port forwarding, no static IP, and your home address stays hidden. Local access is instant on your own network; public access is one click.
What about the hardware kit?
The Baumeister Kit is an optional dedicated box for people who don't want to keep a PC running — pre-configured, silent, plug-and-play. It ships July 2026 with free US shipping, 30-day returns, and a 1-year warranty. Join the waitlist to reserve one; the software is identical either way.
What do I need to run the free software?
A Windows PC (Windows 10 or 11) and an internet connection — Mac support is coming soon. Download, install, set a password and a recovery email, and you're publishing in minutes. Your projects live on your machine — sites stay online while it's running, and start back up automatically when it does.
