# AI use cases for Builder (HeyPuter/builder) Repo: [HeyPuter/builder](https://github.com/HeyPuter/builder) | Use cases: 4 | Page: https://dedupedai.com/use-cases/heyputer-builder/ AI Builder is an open-source, Apache 2.0 licensed web app where you describe a website or app in plain language and the AI builds, previews, and publishes it. This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Build a website from a plain-language description: https://dedupedai.com/use-cases/heyputer-builder/build-website-from-plain-description/ - Start from a template and adapt it to your needs: https://dedupedai.com/use-cases/heyputer-builder/start-from-template-and-customize/ - Let the AI use your other services via MCP: https://dedupedai.com/use-cases/heyputer-builder/connect-mcp-tools-while-building/ - Run AI Builder locally and fork it to customize: https://dedupedai.com/use-cases/heyputer-builder/run-and-fork-builder-locally/ ## How to build a website from a plain-language description with Builder Repo: [HeyPuter/builder](https://github.com/HeyPuter/builder) | Difficulty: Beginner | Time: 15 minutes | Basis: From the README Describe a site in chat, watch the live preview update, and publish it to a public URL. **Who it is for:** A small business owner or creator with no coding skills who needs a simple website for a project, service, or event. **The problem:** Building a website normally requires writing code or hiring someone, which takes time and money before any idea is tested. **The outcome:** A working website you can preview, refine in chat, and share at a public URL. ### Steps 1. Open https://builder.puter.com/ in your browser. 2. Describe the website you want in plain language in the chat. 3. Check the live preview and ask for changes until the site looks right. 4. Publish the project to a public URL when you are ready to share it. ### Prompt to paste into your agent ```text Using the HeyPuter/builder repo's live demo at https://builder.puter.com/, describe a one-page website for in plain language, iterate on it in the live preview, and publish it. Expected output: a public URL for the published site. Verify that the URL loads and shows the content described. ``` ### Caveat The README does not list hosting limits or pricing, so confirm those in the live demo before depending on a published site.

Open https://builder.puter.com/ in your browser. 2. Pick a template from the available templates. 3. Let the template copy into your account. 4. Describe the changes you want in chat and check the live preview. ### Prompt to paste into your agent ```text Using the HeyPuter/builder live demo at https://builder.puter.com/, copy a template that fits into a new project, then request changes that match its purpose. Expected output: an edited project copy in your account. Verify that the original template is unchanged and the copy shows your requested changes in the live preview. ``` ### Caveat The README does not say which templates are available or how many, so check the template list in the live demo.

Open https://builder.puter.com/ in your browser and open your project. 2. Add a remote MCP server connection using the server URL you want to use. 3. Ask the AI in chat to use a specific tool from that server in your project. 4. Check the live preview to confirm the result uses the data or action returned by the tool. ### Prompt to paste into your agent ```text Using the HeyPuter/builder live demo at https://builder.puter.com/, connect the remote MCP server at and ask the AI to use one of its tools to update . Expected output: a project change that uses the tool's result. Verify that the tool call result appears in the live preview and that the connection was made to the URL you provided. ``` ### Caveat The README does not list which MCP servers are supported or how authentication to them is configured, so verify the connection flow in the product. Risk, credentials: Connecting a remote MCP server may require sharing access tokens or keys with that server, so use only servers you trust and scope their access narrowly.

Run `git clone https://github.com/HeyPuter/builder` 2. Run `cd builder` 3. Run `npm install` 4. Run `npm run dev` 5. Open the local development address the dev server prints and make a small change to confirm it updates. ### Prompt to paste into your agent ```text Clone the HeyPuter/builder repo, run npm install and npm run dev, then change to add a small customization. Expected output: the builder running locally with your change visible. Verify that the dev server starts without errors and the change appears after reloading the page. ``` ### Caveat The README gives no Node.js version or dev server address, so check the terminal output and the repo's package files if the commands fail.
