Best for: Traders and developers who want free, aggregated cryptocurrency price and market cap data across thousands of exchanges, plus an API for historical crypto data.
Pricing: Browsing CoinGecko is free; a CoinGecko Premium subscription and tiered developer API plans exist, but exact API prices could not be verified from the pages fetched for this listing.
- CoinGecko's homepage reports tracking 21,702 cryptocurrencies and 1,503 exchanges at time of writing.
- CoinGecko offers a Crypto API, an on-chain DEX API, and an NFT API for developers, documented to cover more than 15 million coins.
- CoinGecko provides a GeckoTerminal product specifically for on-chain DEX price tracking.
- The site is free to use and monetized through advertising, a 'CoinGecko Premium' subscription, and paid API tiers.
- 'Buy' links next to coin prices route to third-party exchange partners rather than executing trades on CoinGecko itself.
Limitations: Not an exchange, so users must go elsewhere to actually buy or sell crypto.; Free web experience is ad-supported with sponsored highlights mixed into the coin list.; Exact API pricing tiers were not confirmed on this pass because the pricing page returned a fetch error.; Includes many low-liquidity meme and micro-cap tokens that add noise for serious research.

What is CoinGecko?
CoinGecko is a cryptocurrency market data website and API provider. It aggregates price, volume, and market-cap data from thousands of centralized and decentralized exchanges into a single reference site, and offers portfolio tracking, an NFT and on-chain DEX tracker (GeckoTerminal), and a developer API covering more than 15 million coins according to its own product description.
CoinGecko tracks live and historical prices, market capitalization, and trading volume for 21,702 cryptocurrencies across 1,503 exchanges, according to the counters shown on its homepage. It also covers NFT collections, on-chain DEX data through its GeckoTerminal product, and offers a public and paid Crypto API for developers who need programmatic access to market data. CoinGecko is free to browse; monetization comes from advertising, a CoinGecko Premium subscription, and tiered API plans for higher call volumes.
Standout feature: Price aggregation methodology that averages trading pairs across 1,500+ exchanges and algorithmically excludes anomalous tickers, producing one unbiased market cap ranking instead of a single-exchange price.
Biggest weakness: CoinGecko is not an exchange: every "Buy" button routes to a third-party affiliate partner, so users still need a separate exchange or wallet to actually trade. The free web experience is also heavily ad-supported, and the useful historical/OHLCV endpoints on the API sit behind paid tiers with per-plan rate limits.
