Pocket Universe (Kerberus)

Pocket Universe is a Chrome browser extension for protecting Web3 assets during wallet transactions. It dynamically reads the website where a transaction is being made and warns users before they sign a transaction that could drain their wallet. The video descriptions also state that it offers $30,000 of coverage per transaction for a fee.

Knockoff is a browser extension that filters pseudo-brand listings from Amazon search results by hiding, dimming, or labeling them. It runs locally in a content script and resolves each listing's brand against user allowlists and blocklists, bundled lists of flagged and established brands, and name heuristics for patterns such as all-caps strings, unusual consonant runs, non-English letter pairs, non-Latin characters, and irregular capitalization. The extension supports Chrome, Firefox, and Safari; the public repository is a frozen, fully local snapshot with no accounts, tracking, or network requests, while maintained auto-updating versions are distributed through browser extension stores.

ThreatXtension is an open-source security tool for analyzing browser extensions and detecting potentially malicious ones. It combines static analysis, permission analysis, VirusTotal intelligence, web-store information, and AI-based assessment.

Endoplexity is a Chrome MV3 side panel and local bridge for agentic control of the browser a person is already using. It lets Claude or Cursor agent CLIs operate existing tabs and logged-in sessions by clicking, typing, filling forms, navigating, switching tabs, uploading files, and reading pages, without sending requests directly to a model or requiring a separate metered API key. The side panel owns the Chrome DevTools Protocol connection and communicates over an origin-pinned WebSocket with a bridge on localhost; the bridge exposes browser tools over token-gated MCP/HTTP and enforces the safety policy, including approval gates and autonomy modes. Pages are provided to the agent as accessibility-tree snapshots rather than raw HTML, and actions return the resulting page state so subsequent turns can resend only changed lines. Its file-reading tool extracts text from PDFs, DOCX, XLSX, PPTX, CSV, JSON, Markdown, and other text files.

Bright Data's Web Unlocker API and Browser API are web-access services for collecting public-site data when ordinary requests encounter anti-bot systems. The Unlocker API handles blocked access and CAPTCHAs, while the Browser API provides remote browsers with stealth features and JavaScript rendering. The videos describe them as infrastructure that manages blocking, retries, and IP selection, including access to a Glassdoor page that a plain Claude request could not open.
