Verify and analyze Ads.txt and App-ads.txt files along with corresponding Sellers.json entries for programmatic advertising compliance.

Helps publishers and ad tech companies validate the integrity of their advertising supply chain by detecting syntax errors, duplicate entries, and cross-referencing publisher-seller relationships in Ads.txt/App-ads.txt and Sellers.json files.

User navigates to a website -> Extension detects the domain -> Fetches the domain's ads.txt or app-ads.txt file -> Parses and validates entries for errors/duplicates -> Fetches corresponding sellers.json for each publisher domain -> Cross-references Ads.txt entries with Sellers.json data -> Displays comprehensive analysis in side panel with summary, details, and seller information tabs -> Allows filtering, searching, and exporting results.

Target users: Publishers / Ad tech companies / Marketers / Programmatic advertising professionals

The main UI logic is in minified 754.js (~540KB) which was not fully deobfuscated, so some edge cases in the UI rendering or error handling might not be fully captured.
Cannot verify if there are server-side components or analytics that might require backend communication beyond the public URL fetching.
The extension stores data in chrome.storage.local which could persist user preferences but does not indicate cloud sync or account requirements.

Monetization

No paid features detected

No evidence of paid features, subscriptions, premium tiers, or payment integration. The extension uses standard open-source libraries (React, Tailwind CSS) with MIT/ISC licenses. Keywords like 'pro' found in static analysis are false positives from library names (e.g., 'react-dom.production.js', 'react-jsx-runtime.production.js') and the word 'provides' in locale messages, not paid feature indicators.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension performs local analysis of Ads.txt and Sellers.json files fetched from public URLs. There is no login UI, no authentication flow, and no requirement to create an account to use the core functionality. The 'account' and 'auth' keywords found in messages.json refer to advertising accounts (publisher IDs, certification authorities) in the Ads.txt specification, not user accounts.
