Lab2.dev

lab2.dev turns a plain-language prompt into a complete working web app, coding it, running it in a hosted runtime and returning a live URL. It suits non-developers who need a real tool rather than a mockup, and it includes built-in model access for generative-AI apps.

lab2.dev is a prompt-driven web app builder. You describe the app you want in plain language, and lab2 generates a complete, working web application, runs it in a hosted runtime, and returns a live URL. No code is required, and there is no local environment to set up, no dependency installation and no separate deploy pipeline. The prompt is the specification; lab2 handles code generation, the AI plumbing, the runtime and the hosting. The tool is aimed at people with an app idea but no development workflow. That includes non-technical founders, analysts and marketers who want a working dashboard or tool rather than a mockup, and developers who want to skip the scaffolding steps. lab2 is also built for generative-AI products specifically: text-to-image playgrounds, chatbots, and data plus AI tools can be assembled with model access already wired in, so the prompt describes the product rather than the infrastructure underneath it. In practice you write a sentence such as "a dashboard that tracks my portfolio" or "an image generator for my brand." lab2 writes real code and boots the app while you watch, and the app is live as soon as it runs. From there you iterate by conversation: ask for a new chart, a filter or a layout change, and the assistant edits the code while the running preview updates alongside. The generated code can be opened and inspected at any point. A community gallery offers another starting point, since you can open a live app another builder made and remix it with your own prompt. Among alternatives, lab2 sits closer to a hosted app builder than to a chat assistant. Asking a general chatbot for code gives you snippets you still have to run and deploy yourself; lab2 owns the runtime and the URL. It also competes with traditional low-code builders, with the difference that the starting point is a prompt rather than a visual canvas. The site leaves several operational questions open, including app limits per account, export options and the data protection details, so those are worth confirming before committing to a plan.
