Not a Clunky Workaround.
Lovable, v0, and Bolt are incredible for building web apps. Cursor is a powerful AI code editor. But Chrome extensions have a completely different architecture. Here's how they compare.
 | Lovable | b | v0v0 | Replit | Cursor | |
|---|---|---|---|---|---|---|
| Primary Output | Chrome Extension | Web Apps | Web Apps | Web Apps | Any Code | Any Code |
| Purpose-Built for Chrome Extensions | ||||||
| Auto-Generates manifest.json, Content & Background Scripts | Automatic | If prompted* | If prompted* | If prompted* | If prompted* | If prompted* |
| Ready-to-Install .zip Export | One click | |||||
| Extension Knowledge Needed | None | Moderate | Moderate | Moderate | Moderate | Some |
| Time: Idea → Working Extension | ~2 min | 15-30+ min | 15-30+ min | 15-30+ min | 10-30+ min | 10-20+ min |
| Cost | From $89 (One time) | $300 to $600/yr ($25-$50/mo) | $300 to $360/yr ($25-$30/mo) | $360 to $1,200/yr ($30-$100/mo) | $240 to $1,200/yr ($20-$100/mo) | $240 to $2,400/yr ($20-$200/mo) |
* These tools can generate Chrome extension code if explicitly asked. The difference is PlugThis does it automatically from a plain English description — no extension architecture knowledge needed.

30 Day "Build Anything" Money Back Guarantee
Try PlugThis for 30 full days. Build extensions, test the templates, see if it fits your workflow. If it is not for you, email me and I will refund every cent. No questions. No hoops.
A quick note on expectations: PlugThis is great for productivity tools, scrapers, sidebar panels, AI assistants, email trackers, and similar extensions. It is not a replacement for a full development team on highly complex enterprise applications. If you are unsure whether your idea is a good fit, message us before you buy and we will tell you honestly.
I built PlugThis because I was tired of buying Chrome extensions that did 80% of what I needed. This tool lets you build the exact 100% you want for the kind of extensions most people actually need.

Trust & Risk
About PlugThis — the Chrome extension builder
What is a Chrome extension builder?
A Chrome extension builder is a tool that generates the code, manifest, and packaging files needed to create a Chrome extension without writing any of it by hand. Most builders generate the Manifest v3 structure, content scripts, popup HTML, background service workers, and icons — everything Chrome needs to load the extension. PlugThis is the only AI builder designed specifically for Chrome extensions, which means it understands the platform's architecture instead of pasting in generic web app code that won't run inside Chrome.
How does PlugThis build Chrome extensions with AI?
You describe the extension in plain English. PlugThis uses Gemini 3.1 Pro to generate the full Manifest v3 package — manifest.json with the right permissions, content scripts that inject into the right URLs, a popup UI that matches your description, a background service worker for events and storage, and a Supabase backend if your extension needs one. The output is a complete unpacked extension you download as a zip, load into Chrome via developer mode, and use immediately. Total time from prompt to working extension is under two minutes.
Can I build a Chrome extension without coding?
Yes. You don't need to know JavaScript, the Chrome extension APIs, the Manifest v3 spec, or how content scripts and background workers communicate. You describe what the extension should do, which sites it should run on, what data it should remember, and any external services it should call. PlugThis handles permissions, file structure, message passing, and packaging. If you ever want to edit the code by hand later, you have full ownership of the generated source — no vendor lock-in.
What kind of Chrome extensions can I build?
Anything Chrome's extension APIs allow. Page summarizers, focus-mode blockers, autofill tools, price trackers, AI writing assistants, meeting transcribers, voice-note recorders, LinkedIn outreach helpers, tab managers, bookmark organizers, scrapers, translators. PlugThis extensions can read and modify any webpage, inject UI overlays, talk to external APIs, store data locally or in Supabase, send notifications, and respond to browser events. Every extension built with PlugThis is Manifest v3 compliant and ready for the Chrome Web Store.
Chrome extension builder FAQ
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.
