Build a Chrome Extension with Vibe Coding
Chrome extensions are one of the most underrated vibe coding projects. They're small, focused, and ship fast. Describe what the extension does, your AI tool generates the manifest, popup UI, content scripts, and background workers. Add YepAPI for data features and you've got a production extension in an afternoon.

How to vibe code a chrome extension
Define the extension concept
One-sentence description: "A Chrome extension that shows SEO metrics for any page I visit." Extensions should do one thing well — keep the scope tight.
Generate the extension scaffolding
Prompt: "Build a Chrome extension with a popup that shows SEO stats for the active tab URL. Use manifest v3, TypeScript, and a clean popup UI." The AI generates manifest.json, popup HTML/JS, and any background scripts.
Add API calls
"When the popup opens, call YepAPI's SEO API with the current tab URL and display domain authority, backlink count, and top keywords." Drop llms.txt so the AI knows the exact endpoints.
Test and package
Load the unpacked extension in Chrome (chrome://extensions → Developer mode → Load unpacked). Test on different sites. When it works, zip it for Chrome Web Store submission.
What to build with Chrome Extension + YepAPI
“Build a Chrome extension that shows the SEO score, domain authority, and top keywords for whatever page I'm viewing.”
“Create a Chrome extension that summarizes any webpage using AI when I click the extension icon.”
“Build a Chrome extension that extracts all emails and contact info from the current page using web scraping.”

Frequently asked questions
Yes — Chrome requires manifest v3 for all new extensions. Make sure to specify this in your prompt. Most AI tools default to v3 now, but double check the generated manifest.json.
Never hardcode API keys in extension code — it's visible to anyone who installs it. Use a backend proxy: your extension calls your server, your server calls YepAPI with the key. Or use Chrome's storage API to let users enter their own key.
Yes. Create a developer account ($5 one-time fee), zip your extension files, and submit for review. Chrome reviews take 1-3 business days. Most vibe-coded extensions pass on the first try if you follow manifest v3 guidelines.
Start vibe coding with one API key.
One API key. 100+ endpoints. Yep, that's it.
