Description Build a free web tool using the HTML5 Gamepad API. A user connects a controller via USB or Bluetooth, and the app measures rest-position drift percentage, circularity error, dead zones and polling rate in real time, then produces a shareable diagnostic report. The free tier shows the report; a Pro tier ($4.99 one-time or $19/year) unlocks calibration profiles, drift history tracking and batch testing for repair shops. Every report includes affiliate recommendations for Hall Effect replacement controllers such as GameSir Nova Lite and 8BitDo, plus DIY repair kits, and a CTA to partner repair services. Offer a B2B dashboard for repair shops at $15/month.
Monetization Affiliate commissions on recommended controllers and kits (10-20% per sale), Pro subscriptions, repair-shop B2B dashboard, and lead generation fees from repair services.
Pros
  1. Solves the exact pain point the article raises (stick drift) with an immediate free utility
  2. No inventory or shipping; pure software with high margins
  3. Viral/SEO potential: ‘test your controller drift’ is a recurring search
  4. Affiliate and B2B revenue can start before paid subscriptions
Cons
  1. iOS Safari does not support Gamepad API well, limiting mobile users
  2. Niche audience size caps revenue unless the B2B repair-shop angle scales
  3. Requires web development skill and ongoing browser compatibility maintenance
  4. Competition from existing tools and open-source projects requires differentiation
