Claude Code can run your server for you.

Log into your Baumeister dashboard and hand it to Claude Code — build new features, fix bugs, publish changes, and deploy entire apps through plain conversation. No manual clicking through settings, no separate deploy step.

Built for builders, freelancers, small businesses, and anyone tired of cloud invoices.

What People Build

One tool, endless things to host.

Baumeister isn't just for side projects — it's a real host for real apps and real websites. Anything you'd normally pay a cloud platform for, you can run from the computer already sitting on your desk.

🧰

Personal tools

A workout log, a chore tracker, a budget dashboard — built exactly for how you live, instead of bent to fit someone else's app.

🏢

Business & client websites

A real site for your business, a portfolio, or a client project — live on your own domain in minutes, no hosting invoice attached.

🚀

New ideas & MVPs

Get a working app in front of real users today. Test the idea before you commit to cloud infrastructure you may never need.

📊

Internal tools

CRMs, inventory trackers, simple dashboards — small software built around how your team actually works, not a rigid template.

📁

File & document sharing

Share files or a portfolio through a real link, served straight from your own computer — nothing uploaded to a third party.

🎓

Learning & prototyping

Practice building and shipping real software without a cloud bill hanging over every experiment.

How It Works

From idea to live link in minutes.

01

Download & open

Install Baumeister on Windows or Mac and open it. Your dashboard launches right there — nothing else to set up, no account required to start.

02

Build

Describe what you want to the built-in AI assistant and it writes and deploys the code for you. Or bring something you built in Claude, ChatGPT, or Cursor and upload it straight in.

03

Publish

Get a free link instantly, or connect your own domain — SSL and routing are handled automatically. Share it, and it's live for anyone.

Built-in AI assistant.
Or bring your own.

Every Baumeister install comes with a built-in AI coding assistant — describe what you want and it builds it right on your computer. You can also build apps in Claude.ai, ChatGPT, or any AI tool you already use, then upload and deploy them. Your hardware, your workflow, no cloud dependency.

Frequently Asked Questions

Do I need to know how to code?
No. Describe what you want to the built-in AI assistant in plain English and it builds it for you. You can also use any AI tool you already know — like Claude.ai, ChatGPT, or Cursor — then upload the files and hit publish.
What can I actually host with this?
Anything from a personal tool to a real business website or client project — static sites, Python apps, Node.js apps, and APIs are all auto-detected and supported. If it can run as software, it can probably run on Baumeister.
Is this free?
Yes. Baumeister the software is free to download and use, with a free baumeister.host link for up to 5 projects. Assistant Pro ($12.99/month) is optional and does two things: it lifts the 5-project cap to unlimited baumeister.host links, and it runs the AI assistant on our key so you don't have to manage your own. On the free plan you get the same assistant with your own key, and no request limits from us.
Can other people actually visit my apps?
Yes. Publish and your project gets a public link anyone can visit — no configuration needed. Want a custom domain like myapp.com? Connect it in a couple clicks and SSL is handled automatically.
Is my data private?
Your projects, files, and server data live on your own computer and stay there. Nothing is sent anywhere unless you explicitly turn on remote access (which is 2FA-secured) or choose to publish a project publicly. Note: Baumeister isn't built or reviewed for regulated data like health records (HIPAA), financial data, or other legally protected categories — it's meant for personal and general business projects.
Does my computer need to stay on?
Yes — your projects are reachable while Baumeister is running on your computer, the same way any server needs to stay powered on. This is exactly what our upcoming dedicated hardware is designed to solve, if you'd rather not tie up your everyday computer.
What about the Baumeister hardware?
We're building a small dedicated server that plugs into your router, so hosting doesn't depend on your everyday computer staying on. It's not available yet — the software you can use today is the fastest way to start. Learn more about the hardware and join the waitlist.
