CoinGecko is the reference free crypto market data source. 15,000+ coin coverage, free API with generous limits, and a clean mobile app. Non-negotiable stack piece for anyone who tracks crypto prices, market cap, or trading volumes.
What CoinGecko is
CoinGecko aggregates market data from 800+ exchanges across 15,000+ crypto assets. Founded 2014, it's one of crypto's longest-running data infrastructure providers.
CoinGecko vs CoinMarketCap
CoinGecko and CoinMarketCap are the two dominant free market data sources. CoinGecko's free API is more generous (30 calls/min free); it's independent (CMC is owned by Binance); and it's often first to list new tokens.
Pricing
- Free: fully usable — coin data, historical charts, portfolio tracking, watchlists
- Pro API: higher rate limits for developers
Verdict
CoinGecko is essential free market data infrastructure. Every crypto user should have it bookmarked; every developer should default to its API.
