Bitcoin Climber

A live Bitcoin coin climbs the edge of your browser. Its height shows where BTC stands between $0 and its all-time high.

Bitcoin Climber adds a small, animated Bitcoin coin to the right edge of every browser tab. Its vertical position on your screen represents the current BTC price as a proportion of the all-time high — bottom of screen is $0, top is the ATH. How it works: The coin fetches the live BTC price from CoinGecko every 60 seconds The all-time high updates automatically — no manual updates needed Hover the coin to see the exact price, ATH, and how far below the all-time high you are Works on every website and every tab automatically Built to last: Uses Shadow DOM isolation — no website can break or hide it API calls run in a background service worker, unaffected by any site's Content Security Policy Survives single-page app navigation (React, Next.js, etc.) Bitcoin Climber is completely free. Donations are appreciated but never required.
