K-12 web content filter and anti-evasion defense for student Chromebooks, deployed and managed by school IT administrators

Students on managed Chromebooks use proxy sites, filter evasion exploits, tab spam attacks, and Google Sites abuse to bypass school web filters and access blocked content (games, proxies). This extension provides enterprise-grade detection and blocking of these evasion techniques.

School admin deploys extension via Google Workspace Admin Console → Admin optionally configures blocking rules, tab limits, and domain allowlists/blacklists via managed storage policies → Extension silently runs on student Chromebooks → Detects and blocks proxy sites, filter evasion exploits, tab spam, and Google Sites abuse → Closes offending tabs and blocks suspicious network requests → Reports forensic logging via heartbeat system

Target users: K-12 school IT administrators deploying managed Chromebooks / School district technology directors / Google Workspace for Education administrators

No external authentication or payment infrastructure exists to investigate further; the extension is purely client-side filtering logic.
The managed_schema.json suggests optional admin-configured configUrl that could host remote configuration, but this is an admin deployment pattern, not a user-facing feature requiring login or payment.
Extension has no popup UI, options page, or settings interface visible to end users - all configuration is admin-pushed via managed storage.

Monetization

No paid features detected

The extension explicitly states 'Free forever' in its description. No premium, subscription, payment, upgrade, or billing references exist in any source file. All 'pro' keyword matches are false positives from proxy pattern detection names (e.g. 'AlloyProxy', 'TacoProxy', 'Nebula Proxy') and educational domain names (e.g. 'prodigygame.com', 'proquest.com'). The 'license' match is a comment about school-licensed video conferencing tools. No payment APIs, license checks, or feature gating code exists.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: No login, authentication, or account creation functionality exists anywhere in the extension. The extension runs as a silent background service worker with content scripts. The only 'auth' keyword hit was a false positive in a comment about Google Sites inspector. Configuration is managed by school administrators via Chrome managed storage (Google Workspace Admin Console), not by student login.

Permission risk
