Developer debugging tool for Klaviyo integration

Helps developers verify if Klaviyo JS is installed correctly on a website and debug client-side events sent to Klaviyo.

User visits a website -> Clicks extension icon to check for Klaviyo -> If detected, opens Chrome DevTools to view the Klaviyo panel for detailed event debugging and integration info.

Target users: Web Developers / Frontend Engineers / Marketing Technologists

The analysis is based on static source code. Dynamic behavior of the DevTools panel (index.html/app.js) is complex and minified, but the core logic in popup.js and background.js is clear.

Monetization

No paid features detected

The extension is free. There is no code implementing payment processing, subscription checks, or feature gating. Keywords like 'pro' and 'license' refer to third-party libraries (React) or Klaviyo event names ('Viewed Product'), not the extension's business model.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a local debugging tool that inspects the current webpage's DOM for Klaviyo scripts. It does not require the user to authenticate with the extension or with Klaviyo to function. The 'Account ID' shown is scraped from the website's script tag, not from a user account.
