External website (gasnow.io) may have additional paid features not reflected in the extension itself

Monetization

No paid features detected

No subscription, premium tier, upgrade prompts, payment processing, or feature gating detected in the extension source code. All 'pro' keyword matches are from minified JavaScript library code (property names) and MIT license headers, not paid feature indicators. No Stripe, billing APIs, or payment UI found. The extension appears to be a completely free gas fee tracking utility.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login, authentication, or user account functionality detected in the extension source code. The extension only communicates with api.mct.club for public gas price data (api.mct.club/api/v2/gas_price/estimate_v3). No authentication headers, session tokens, or user account flows found. The extension uses chrome.storage solely for local user preferences, not for account management.
