Exchange Market Radar is an independent, open dataset and set of comparison pages for centralized crypto exchanges. It records what each exchange publicly lists and detects when that changes.
The site is built and maintained by David García, an independent developer based in Spain. It is not owned by, sponsored by or affiliated with any exchange, and it carries no affiliate links.
Exchange catalogs change daily: assets are added and delisted, markets open and close, networks are switched on. Those facts are public but scattered across dozens of API endpoints and changelogs. The radar collects them in one place, keeps the history, and shows where each figure comes from.
A scheduled job reads public, unauthenticated endpoints from each monitored exchange once a day: asset lists, trading-pair catalogs, network and API documentation, and official changelogs. Each record is stored as a fact with its source and the time it was observed. A change is reported only when two snapshots differ and the evidence can be shown.
Figures are catalog counts. They are not prices, trading volume, liquidity, fees or availability in a given country, and “not collected” never means “unsupported”. The data sources guide lists every venue, source and last check.
The exchange-level dataset is free to download as CSV or JSON from the data page, and the code is open source.
If a figure looks wrong, open an issue on the GitHub repository with the page URL and what you expected. Corrections to the collectors are published in the repository history.
