PlugThis
Describe a Chrome extension in plain English, get working code in minutes
Overview
PlugThis is a Chrome extension builder, and only a Chrome extension builder. That narrowness is the point. General AI app builders like Lovable, Bolt, and v0 are built around web apps, and the manifest, content-script, and service-worker structure that Chrome extensions require tends to trip them up. PlugThis is built around that exact structure from the start, so a prompt turns into a real Manifest v3 extension you can load in Chrome within a few minutes, not a half-working mockup you have to fix by hand.
It launched on Product Hunt in mid-2026 and landed at #3 for the day with a genuinely warm reception, including detailed technical back-and-forth in the comments about token storage and permission scoping, the kind of scrutiny that's hard to fake. That said, it's a young product with a thin public track record outside that launch. If you need a Chrome extension and don't want to learn the Chrome extension APIs, it's worth a look. If you need anything outside that lane, it's not built for you.
Key Features
Plain-English Building: Describe the extension you want and PlugThis generates the Manifest v3 code behind it, no JavaScript or Chrome API knowledge needed.
Full Extension Structure: Auto-generates the manifest file, content scripts, background service workers, and popup UI as a working set, not a fragment.
Optional Backend: Wire in Supabase or your own OpenAI or Gemini API key for extensions that need a database or AI features.
Own Your Code: Download the full source anytime. Nothing is locked behind PlugThis's platform.
Chrome Web Store Ready: Outputs a .zip you can submit directly, which is where most general AI builders leave you stranded.
Starter Templates: 14+ pre-built extensions (CSS inspector, privacy blur, sticky notes, font previewer) to start from instead of a blank prompt.
Pricing
Starting price
$9.99/mo
Starter: $9.99/month. 1 extension, unlimited chat refinement, build and ship to the Chrome Web Store, own all code.

Pros
Purpose-Built for Extensions: Handles the manifest, content-script, and service-worker structure that trips up general AI app builders.
Fast: Users report a working extension loaded in Chrome within about five minutes of signing up.
No Lock-In: Full source code is downloadable anytime and yours to publish, sell, or modify.
Goes All the Way to the Store: Outputs a Chrome Web Store-ready package, covering the submission step other builders skip.
Strong Launch Reception: Landed #3 on Product Hunt for the day with a 5.0 rating and detailed, technically credible user engagement.
Cons
Thin Track Record: Public information is mostly limited to its own site and its Product Hunt launch, there isn't much independent, long-term usage data yet.
Very Narrow Use Case: Only builds Chrome extensions. If you need a web app, mobile app, or anything outside that lane, this isn't the tool.
Promotional Pricing Confusion: The Builder plan's listed rate ($9.99/mo) is a limited Product Hunt discount for the first 50 signups before it reverts to $29.99/mo, so what you actually pay long-term depends on when and how you sign up.
Unproven at Scale: No independent reviews yet on how it holds up for complex extensions with heavy permissions or multi-service backends.
What Makes It Unique
Chrome Extensions Only, Done Properly: Where Lovable, Bolt, and v0 are general-purpose builders that stumble on Chrome's manifest and service-worker architecture, PlugThis is built around that architecture from the ground up.
