Steam's native store pages lack detailed price history, concurrent player stats, and various convenience features that gamers want when researching games

User installs extension → browses Steam Store or Community pages → extension automatically injects SteamDB data panels (price history, player stats, update info) and convenience buttons (quick sell, SteamDB links, PCGamingWiki links) into the page. User can configure which features are enabled via the options page. Optional: user enables highlighting feature to see owned/wished games on steamdb.info (requires Steam Store login in browser).

Target users: Steam gamers and power users / Bargain hunters tracking game prices / Steam community members managing inventories and achievements

Could not verify steamdb.info website's own login requirements (the extension itself has no login but the steamdb.info website may have features requiring accounts)
The deterministic heuristic had several false positives for paid keywords that were all related to Steam's own systems rather than extension monetization

Monetization

No paid features detected

The extension is completely free and open source (https://github.com/SteamDatabase/BrowserExtension). All detected paid/pro keywords are false positives: 'subscribe'/'subscriber' refer to Steam's Subscriber Agreement (SSA) which the extension auto-accepts (scripts/community/market_ssa.js), 'subscription' refers to Steam's game subscription selector (scripts/store/subscriptions.js), 'purchase' refers to Steam game purchase blocks (scripts/store/app.js). No payment platforms, billing APIs, upgrade prompts, or premium tiers exist anywhere in the source code. No Stripe, no in-app purchases, no license checks.

Confidence: 92
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension itself has no login system. Its core features (displaying lowest prices, concurrent players, adding SteamDB links, skipping age checks, quick sell buttons, etc.) work without any authentication. Some optional features (highlighting owned/wished games on steamdb.info) require the user to be logged into the Steam Store in their browser, as evidenced by FetchSteamUserData fetching from store.steampowered.com/dynamicstore/userdata/ with credentials:include, and the error message 'Are you logged on the Steam Store in this browser?' at scripts/background.js:127. The locale string at _locales/en/messages.json:459 also states 'You have to be logged in on the store for this to work.' But this is for optional enhancement features, not the core product workflow.
