Chrome Extension Generator

Type what your extension should do. Get a working Chrome extension. PlugThis generates the complete Manifest v3 package — code, manifest, popup, icons — in under two minutes.

What does a Chrome extension generator do?

A Chrome extension generator takes an input — a description, a template, a set of options — and produces the files Chrome needs to load an extension. The full package includes the manifest with the right permissions and content script declarations, the content scripts that inject into target sites, the popup HTML and JavaScript, the background service worker for events and storage, and the icons in the sizes Chrome requires.

PlugThis takes plain-English descriptions as input. You write what you want. The generator builds it.

What's in the generated package?

Every extension PlugThis generates includes:

A manifest.json declaring the extension name, version, permissions, content scripts, popup, icons, and Manifest v3 compliance fields. Content scripts that inject the right behavior into the right URLs — no global injection, no permission overreach. A popup HTML and JavaScript file that renders when the user clicks the extension icon, sized correctly for Chrome's popup constraints. A background service worker handling events, alarms, message passing, and persistent state via Chrome storage APIs. Icon files at 16×16, 48×48, and 128×128 — the sizes Chrome expects. Optional: an options page if the extension has user-configurable settings, a Supabase backend if data needs to persist beyond local storage.

The generated zip loads directly into Chrome via chrome://extensions → Load unpacked.

How fast is generation?

Description-to-code takes about 60–90 seconds. Loading it into Chrome takes another 20 seconds. Total time from prompt to working extension: under three minutes. If iteration is needed — refining behavior, adding features, fixing edge cases — each iteration takes about the same time.

For comparison: building a Chrome extension by hand from scratch, even for an experienced developer, is a 4–8 hour project once you account for manifest setup, message passing wiring, popup state management, and Chrome Web Store packaging. PlugThis collapses that into minutes.

Frequently asked questions

Does the generator output Manifest v3?

Yes, every extension. Manifest v2 was deprecated in 2024 and is no longer accepted by the Chrome Web Store.

Can I customize what's generated?

Yes — describe what you want in the prompt and PlugThis generates accordingly. After the first build, you can iterate by describing changes.

Are the generated extensions production-ready?

Yes. The output is a complete, packageable extension that can be submitted to the Chrome Web Store as-is.

Can the generator handle extensions that need backends?

Yes. PlugThis sets up Supabase tables, auth, and storage automatically when an extension needs persistent data.

What format is the output?

A downloadable zip with the unpacked extension structure. Load it directly into Chrome's developer mode, or zip it for Chrome Web Store submission.
