Free CoinGlass alternative
CoinGlass is the best-known crypto derivatives data site, and for multi-exchange aggregation it is genuinely strong. But most traders use a handful of features: liquidation heatmaps, funding rates, open interest and sentiment. ByKaranteli covers those free, live, and without an account. Here is the honest side-by-side.

Where to start
The three pages people usually come from CoinGlass for: BTC liquidation map, funding rate arbitrage scanner and the open interest leaderboard. For sentiment there is the live Fear & Greed index and BTC dominance. Builders can pull everything from the free JSON API.
What CoinGlass does better
Honesty is the whole point of this site, so: CoinGlass aggregates liquidation and open interest data across many exchanges while our model aggregates six venues from our own liquidation feeds; it keeps years of history while our public windows are shorter; and it ships a mobile app. If your workflow needs those, use CoinGlass. If you need live core data without a paywall, recorded by our own network with provenance on every row and a public status page that shows the freshness of every feed, that is what we built.
FAQ
Is there a free alternative to CoinGlass?
Yes. ByKaranteli covers the core CoinGlass use cases free and without an account: liquidation maps for 201 major perpetuals aggregating six major venues through our own collection network, funding rates compared across 33 exchanges, an open interest leaderboard, and live market indices including Fear & Greed and BTC dominance. There is also a JSON API on a free account key.
What does CoinGlass do better?
CoinGlass aggregates more exchanges and more coins, keeps longer history, and offers a mobile app. If you need liquidation aggregation across more exchanges and coins than our six-venue model covers, or years of archived derivatives data, CoinGlass's paid tiers are the stronger tool. ByKaranteli focuses on free, live data from our own collectors with provenance on every row.
Is the liquidation map the same as CoinGlass's heatmap?
Same concept, independent model. Both estimate where leveraged positions would be liquidated. Ours aggregates six venues from our own liquidation feeds, refreshes every 10 minutes, is free without login, and highlights the nearest actionable clusters above and below the current price.
Does ByKaranteli have an API like CoinGlass?
Yes, and the Free API plan costs nothing: a free account key, 30 requests a minute, no quota purchase (Builder from $49 a month raises the rate and adds member depth). Public JSON endpoints cover funding arbitrage, indices, pressure scores, leaderboards and per-symbol data, with a machine-readable catalog at /api/v1/public/manifest and docs at /developers.
