Can I really build a Chrome extension without coding?

Yes. PlugThis generates the full Chrome extension code from a plain-English description. No JavaScript, no manifest format, no Chrome API knowledge required. Most users have a working extension loaded in Chrome within five minutes of signing up.

Does PlugThis support Manifest v3?

Yes. Every extension PlugThis generates uses Manifest v3 — the current Chrome standard. Manifest v2 was deprecated in 2024 and extensions using it are no longer accepted in the Chrome Web Store. PlugThis output is fully compliant.

Can I publish PlugThis extensions to the Chrome Web Store?

Yes. The output is a complete, packageable extension. Pay the one-time $5 Chrome developer fee, upload the zip, fill in store listing details, and submit for review. Most extensions are approved within a few days.

What can a Chrome extension actually do?

Read and modify any webpage, inject UI elements into existing sites, communicate with external APIs, store data locally, intercept network requests, control tabs and bookmarks, send notifications, respond to keyboard shortcuts. PlugThis can wire up any of these from a plain-English description.

How is PlugThis different from ChatGPT or Lovable for building extensions?

General AI tools and web app builders generate extension code in pieces and stitch them together inconsistently. You end up debugging missing manifest entries, wrong permission scopes, broken content script injection, or build paths that don't match Chrome's loader. PlugThis is built specifically for Chrome extensions — it knows the file structure Chrome expects, validates the manifest, packages everything correctly, and gives you a working unpacked folder on the first try.

What exactly is PlugThis?

PlugThis is an AI-powered Chrome extension builder. You describe what you want in plain English, and it generates a complete, working Chrome extension including the popup UI, content scripts, background workers, manifest file, and everything else. No coding required. Think of it as ChatGPT, but instead of giving you text, it gives you a working Chrome extension you can install immediately.

Do I need to know how to code?

No. You describe what you want in plain English, and PlugThis writes the code for you. All it takes is saying "Build me an extension that highlights all email addresses on any webpage." If you do know how to code, you can download and edit the source code directly.

How long does it take to build an extension?

The AI generates your first working version in about 2 minutes. From there, you iterate: "change the color," "add an export button," "make it work on Gmail only." Each iteration takes another minute or two. Most people go from idea to finished extension in 15-30 minutes. Compare that to weeks of development or $5,000-$15,000 hiring a developer.

Can I really build any Chrome extension?

PlugThis handles simple to moderately complex extensions very well, including productivity tools, scrapers, UI customizers, AI assistants, email trackers, sidebar tools, and more. We rebuilt real, published extensions end to end and put the results on this site — eight written up, six on video, each with the time it took. For highly specialized enterprise extensions with complex native integrations, you may need a developer for the final 10%. But PlugThis still gives you the 90% head start.

Is the AI generated code actually good?

PlugThis generates clean, Manifest V3 compliant code using Chrome's latest APIs. It is not a generic code generator but rather a purpose-built tool for Chrome extensions, which means it understands content scripts, service workers, permissions, and popup architecture. That said, complex extensions may need a few iterations to get right. That is why every plan includes unlimited builds so you can refine until it is exactly what you want. You can also download and manually edit the code at any time.

What if I need changes after building?

Just tell PlugThis what to change. "Make the button bigger." "Add dark mode." "Include export to CSV." "Only run on LinkedIn pages." It updates the extension instantly. No rebuilding from scratch. On the paid plans these refinement chats are unlimited; the AppSumo lifetime tiers include a monthly build allowance.

Can I export the code and own it completely?

Yes. You download the complete source code with every file and every line included. It is a standard Chrome extension folder you can open in any code editor, modify however you want, and load into Chrome without PlugThis. There is no vendor lock in. No obfuscated code. No "you can only run it through our platform" restrictions. The code is yours.

Can I build extensions to sell?

Yes. You own the IP for everything you build. Publish to the Chrome Web Store, sell on marketplaces, offer custom builds to clients, or bundle extensions into a SaaS product. There are no royalties, no revenue sharing, no restrictions on commercial use. Freelancers and agencies use PlugThis to build Chrome extensions and charge clients $1,000-$15,000 per project.

Can I use this for client work and white label?

Yes, on all tiers. Build extensions for clients, deliver the source code, and charge whatever you want.

One LTD. A lifetime of Chrome extensions.

Raison d’être

We used to think about where PlugThis fits next to the big builders.

Lovable, v0, Bolt and Emergent will take a sentence and hand you back a working app by the afternoon. They remind us of McDonald’s, Wendy’s and Burger King. Enormous menus, same quality every time, at prices you can’t argue with.

But you can’t get a hot dog at McDonald’s. None of them were built for Chrome extensions. Ask for one and you’ll usually get something extension-like that doesn’t quite load.

PlugThis is the hot dog cart down the street. One thing on the menu. Chrome extensions, nothing else.

And we make the best hot dogs. Period.

Trust & Risk

$9.99/month for the Starter plan, cancel anytime. No setup fees, no annual contract, no hidden costs. If you need more than one extension, Builder is $29.99/month for three. That's it: two plans, monthly billing.

Yes. PlugThis will build you a working Chrome extension from your description. If the code we generate doesn't work, email us within 7 days and we refund every cent. You keep everything you built. No questions, no hoops, no store credit.

Yes. It's a monthly plan, cancel whenever you want from your account settings. No lock-in, no exit fees. The extensions you've already built stay on your machine and keep working forever.

BYOK = Bring Your Own Key. You plug in your own OpenAI, Gemini or Groq API key in Settings, and it powers AI features inside the extensions you build. This means you're never marked up on AI usage, your costs stay tiny (often under $1/month), and you can switch providers anytime. We never charge a per-token fee or middleman your AI spend.

Yes. You own all the code, so publish, sell, or share it. PlugThis generates Manifest V3 compliant extensions that follow Chrome Web Store policies, so the typical rejection reasons (excessive permissions, vague descriptions, missing privacy policy) are handled by default. You'll need a Chrome Developer account ($5 one-time fee from Google) and to write your store listing.

Email support answered within one business day, a help centre, and video walkthroughs on our YouTube channel. Builder plan customers get priority support. We actively monitor tickets and reply to every one.

Technical

Yes. Every extension PlugThis generates uses Manifest V3, which is Chrome's current and required standard. This means your extensions will not break when Google fully removes Manifest V2 support. PlugThis handles service workers, content security policies, and permission declarations correctly out of the box.

PlugThis generates extensions that follow Chrome Web Store policies, ensuring they are Manifest V3 compliant, use minimal permissions, and avoid remote code execution. The three most common rejection reasons (excessive permissions, vague descriptions, missing privacy policy) are handled by default. You will still need a Chrome Developer account ($5 one-time fee) and to write your store listing, but the extension code itself is built to pass review.

Because PlugThis generates Manifest V3 code using stable Chrome APIs, routine Chrome updates should not break your extensions. If a major API change does affect your extension, you can regenerate or update it in PlugThis with a few clicks. You also have the full source code, so a developer can fix it independently if needed.

Supabase is an open-source backend platform (think Firebase, but open-source). PlugThis auto generates the code to connect your extension to your Supabase account, giving your extensions user authentication, database storage, and server-side logic. You create a free Supabase account, paste your project URL and key into PlugThis, and your extensions get a full backend without you writing any server code.

There are two types of AI in PlugThis. First, our AI that builds your extensions that runs on our servers using a mix of open-source and closed-source models, and is included in your plan — unlimited on the paid plans, and subject to a monthly allowance on the AppSumo lifetime tiers. Second, for AI features inside the extensions you build, such as summarization, writing assistants, and auto repliers, you bring your own API key. OpenAI, Google Gemini and Groq are all configured directly in your Settings. Through Groq, you can run powerful open-source models like Qwen and Kimi K2 that are 90 95% as capable as closed-source models for free or near free. You pick the provider, you control the costs.

About PlugThis

The Chrome extension builder.

A Chrome extension builder generates the code, the manifest and the packaging a browser extension needs, without you writing any of it by hand. PlugThis is built only for Chrome, so it works with the platform’s architecture instead of pasting in generic web app code that won’t run inside a browser.

Describe what you want in plain English and PlugThis generates the full Manifest v3 package: a manifest.json with the right permissions, content scripts scoped to the right URLs, a popup interface, a background service worker, and a Supabase backend when the extension needs one. It takes about two minutes.

You don’t need to know JavaScript, the Chrome extension APIs or the Manifest v3 spec. Say what the extension should do, which sites it runs on, and what it should remember. Permissions, file structure, message passing and packaging are handled for you, and the source code is yours to keep.

People build page summarisers, focus blockers, autofill tools, price trackers, AI writing assistants, meeting transcribers, tab managers, scrapers and translators. Anything Chrome’s extension APIs allow. Every build is Manifest v3 compliant and ready for the Chrome Web Store.
