More 4.5. I find it really useful for research to see what companies are using and if it is applicable to industries I work in.

AI product read

Detect and display the technology stack of any website the user visits

Helps developers, marketers, and competitive analysts identify frameworks, CMS, analytics tools, WordPress plugins, themes, fonts, ad networks, and other technologies powering any website

1. User visits any website. 2. Content script collects page HTML, global variables, and font information. 3. Background script sends data to whatruns.com API for pattern matching. 4. Results are cached per tab. 5. User clicks extension icon to see a popup listing all detected technologies grouped by category (CMS, Analytics, JS Libraries, etc.), with icons and links to each technology's website.

Target users: Web developers researching tech stacks / Digital marketers doing competitive analysis / Product managers evaluating technologies / Tech enthusiasts curious about website infrastructure

The extension communicates with whatruns.com API endpoints (get_site_apps, analyse/page, analyse/path) for technology detection; the server-side detection logic is not available for review
Cannot confirm whether the whatruns.com website itself offers paid business plans separate from the extension
The 'follow' feature's server-side behavior (notification delivery) could not be fully verified from client code alone

Monetization

No paid features detected

All paid keyword matches are false positives from technology category names that the extension detects (e.g., 'Payments', 'Paywalls', 'Programming Language' contain substrings 'payment', 'paywall', 'pro'). 'Upgrade' matches are from humorous server maintenance error messages (e.g., 'server upgrade'). The extension has no payment UI, no subscription tiers, no Stripe/payment integrations, no feature gating, and no premium prompts anywhere in the source code. The extension is entirely free to use.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: Login exists but is only required for the optional 'Follow' feature (tracking website technology changes). The core workflow — detecting technologies on any visited website — works without login. The sign-in heading explicitly states 'Sign in to follow' (_locales/en/messages.json line 4). The isLoggedIn() function in popup_final_extension.js only triggers when the user clicks the 'Follow' button, and the technology detection in popup_final.js and background.js operates independently of authentication state.
