AI App Builder: Build Working Apps from a Single Sentence
Most no-code tools still require you to learn their interface. mk0r skips that entirely. Describe what you want in plain English, watch it stream into a working app in real time, and iterate with words instead of clicks.
Why Text Input Beats Drag and Drop
Traditional no-code builders give you a canvas and a component library. You drag elements, configure properties, wire up logic. The learning curve is lower than code, but it still exists.
mk0r replaces that entire interaction model with a text prompt. You write what the app should do. Claude AI interprets it and generates complete, working HTML, CSS, and JavaScript. The output is real code you can inspect, modify, and deploy.
Two Modes for Two Needs
Quick Mode
Generates standalone HTML/CSS/JS apps using Claude Haiku. Best for simple tools, calculators, landing pages, and single-purpose utilities. Results appear in under 30 seconds.
VM Mode
Spins up a full cloud VM with Vite, React, TypeScript, and Playwright. A Claude agent works inside the VM: writing code, running the dev server, testing in a real browser. You watch the entire process streamed in real time via screencast.
The VM lands at /app with Tailwind CSS v4 already configured and the dev server running on port 5173 with HMR. The default agent system prompt is defined at src/core/e2b.ts:170 and tells Claude exactly what tools and conventions to expect.
You don't wait for the VM to boot. The homepage fires /api/vm/prewarm the moment the page mounts, so a sandbox is already warming in a Firestore-backed pool by the time you finish typing. See how the prewarm pool actually works for the latency math.
What Makes mk0r Different
- Zero friction start: no account, no payment, no onboarding. Just type and build.
- Real code output: every app is HTML/CSS/JS you own. No vendor lock-in, no proprietary format.
- Iterative refinement: describe changes in follow-up prompts. The AI modifies the existing app rather than starting over.
- Live streaming preview: watch the app take shape in real time as the AI generates it.
- Full-stack VM mode: for complex apps, get a complete React + TypeScript project running in a cloud VM with a real browser for testing.
Common Use Cases
Frequently asked questions
Do I need to create an account to use mk0r?
No. mk0r requires zero signup. Visit the site, type your idea, and get a working app. No email, no password, no friction.
What kind of apps can mk0r build?
mk0r generates full HTML/CSS/JS web apps. Common examples include habit trackers, budget planners, recipe scalers, quiz apps, and study card tools. For more complex apps, VM mode spins up a full Vite + React + TypeScript environment.
How is mk0r different from other no-code tools?
Most no-code tools require you to learn their interface, drag blocks, and configure settings. mk0r takes a single sentence and generates a complete working app. You iterate with follow-up prompts instead of clicking through menus.
Can I edit the generated apps?
Yes. Every app outputs real HTML, CSS, and JavaScript. You can download the code and modify it in any editor. In VM mode, you get a full React + TypeScript project you can continue developing.
How long does it take to generate an app?
Quick mode generates standalone apps in under 30 seconds. VM mode, which creates full-stack React apps with a dev server and testing, takes 1 to 3 minutes depending on complexity.
