CoinGecko is the most widely used free crypto data platform in the world, tracking over 10,000 cryptocurrencies across hundreds of exchanges. Founded in 2014, it provides real-time price data, trading volume, market capitalisation, liquidity scores, developer activity metrics, and community data — making it the best free starting point for fundamental research and market overview.

CoinGecko is not a technical screener — it does not offer indicator-based filtering or chart pattern detection. But as a free resource for understanding which assets are gaining momentum, tracking new listings, monitoring DeFi protocols, and researching project fundamentals, it is unmatched at its price point of zero.
