¹ Binance's public liquidation stream sends at most one liquidation per symbol per second, so any site using it (this one included) shows a sample of Binance liquidations. CoinGlass says the same about its Binance data.
² Alert channels as CoinGlass lists them; we have not checked which are free.
³ Available on the free tier, so also included with Prime; Prime extends heatmap coin coverage, history and automatic refresh.
— means we have not verified it either way. Check coinglass.com for its current features.
⁴ Heatmap access: CoinGlass Prime FAQ, checked . Its listed history ranges do not establish identical behavior across heatmap models. Other competitor facts retain the general review date above.
Free CoinGlass API alternative: switching map
These public JSON endpoints work without an API key or signup. This is a different schema and not a drop-in replacement for CoinGlass: adapt your field names, units and error handling. It does not provide CoinGlass proprietary models, paid history, ETF flows or other unsupported datasets.
Current funding and open interest snapshot
Use /api/markets for every tracked coin, with price, volume, funding and OI in nested market rows. This is the full current snapshot, not historical funding or OI.
curl 'https://swolecharts.com/api/markets'
Recorded open interest history
Use /api/series/oi for BTC aggregate perpetual OI in USD: time/value arrays, with epoch-millisecond timestamps. This example requests seven days in hourly buckets; available history begins when recording started. Empty arrays, unavailable data and coverage gaps are not evidence of zero OI.
curl 'https://swolecharts.com/api/series/oi?base=BTC&range=7d&step=1h'
Rolling liquidation totals
Use /api/liquidations for rolling totals by venue and coin, plus the biggest and latest orders since the process started. Binance's public feed sends at most one liquidation per symbol per second: these sampled totals are a lower bound, not complete market liquidations.
curl 'https://swolecharts.com/api/liquidations'
For the shared /api/series family request budget and keyless/keyed history and point limits, see API key and rate limits and the series parameters. Those series limits do not describe the /api/markets or /api/liquidations snapshots. Check API terms before integrating.
What you get here, free
- Live volume spikes with sound. The spike feed updates every few seconds and can beep or send a desktop notification when a spike matches your filters.
- What happened next. Every spike shows the price move 5 minutes, 15 minutes and 1 hour later, with averages per side on the pump scanner pages.
- Liquidation heatmaps. An estimated liquidation heatmap and map for the coins with the most open interest, over 12 hours to 30 days.
- Hyperliquid whales. The whale tracker shows the largest open positions and whale moves from real on-chain positions.
- Hyperliquid HIP-3 coverage. Stock, index and commodity perps with funding, open interest, OI-cap use and mark-vs-oracle basis.
- BTC and ETH options. Max pain, open interest by strike and expiry and put/call ratios from Bybit and Binance options, not the whole options market.
- Server alerts. Set alert rules for funding, open interest, liquidations, volume spikes or price and get them on Telegram or as browser push notifications, even with this site closed.
- Auto-refresh at no cost. The live pages (spike feed, liquidations, funding, open interest) update on their own; CoinGlass lists auto-refresh as a Prime feature.
- Free API. The JSON endpoints behind these pages are public: no key, no signup. See the API switching examples.
- No login. No account, no email. Filters and watchlists stay in your browser. Alert rules are stored on our server and managed with a private token your browser keeps.
- Independent. Not owned by an exchange. Some trade links are referral links, disclosed in the footer; we never sell placement in the data.
What CoinGlass has that we don't (yet)
- One liquidation heatmap model, estimated from open interest changes; CoinGlass Prime offers several heatmap models.
- Options data covers BTC and ETH on Bybit and Binance only, not Deribit or the whole options market.
- No ETF flows.
- No alert delivery by Discord or email: alert rules are delivered by Telegram or browser push notifications.
- Shorter history for open interest, funding snapshots and liquidations: it starts when this site began recording them.

CoinGlass alternative FAQ
Is CoinGlass still free after the CoinMarketCap acquisition?
CoinGlass says its pricing and free tools are unchanged after the deal was announced on 25 September 2026. Its paid Prime plan costs $28 a month ($78 a quarter or $268 a year) and extends heatmap coin coverage, history and auto-refresh; API plans are separate and start at $29 a month.
Who owns CoinGlass?
CoinMarketCap announced that it had acquired CoinGlass on 25 September 2026 (press release). Binance acquired CoinMarketCap in 2020 (background).
What is the best free CoinGlass alternative?
It depends on what you use CoinGlass for. For live volume spikes, funding rates, open interest, liquidations, liquidation heatmaps, Hyperliquid whales and HIP-3 markets across 10 exchanges including Binance, Bybit and Hyperliquid, this site is free with no login. Coinalyze offers free derivatives charts, and loris.tools focuses on funding arbitrage. This site has no ETF flows, and its options data covers only BTC and ETH on Bybit and Binance; CoinGlass has both.
Does Swolecharts have a liquidation heatmap?
Yes. The liquidation heatmap estimates where positions would be liquidated for the coins with the most futures open interest, over 12 hours to 30 days, with a liquidation map of the levels still open. It is a model built from the open interest changes this site records. For Hyperliquid, the Hyperliquid liquidation map uses real tracked positions instead. CoinGlass offers free BTC and ETH heatmaps with 6- and 12-month views, without auto-refresh. Prime extends coin coverage, history and automatic refresh (CoinGlass Prime, checked 20 October 2026). These listed history ranges do not establish identical behavior across heatmap models.
Is the liquidation data complete?
Not for Binance, on any site that uses its public feed: Binance sends at most one liquidation per symbol per second, so busy moments are sampled. CoinGlass notes the same about its Binance data. Treat Binance liquidation totals as a lower bound.
Is there a free CoinGlass API alternative?
Yes, for supported datasets: use /api/markets for current funding and OI, /api/series/oi for recorded OI history, and /api/liquidations for rolling liquidation totals. These anonymous GET endpoints use a different schema and are not a drop-in replacement for CoinGlass. They do not supply its proprietary models, paid history or ETF flows. Binance liquidations are sampled lower bounds. See the switching examples and shared series-family limits before integrating.
Do I need an account?
No. Every page here is free and works without a login or sign-up. Sound alerts, desktop notifications, filters and your watchlist run in your browser. Alert rules for Telegram or browser push are stored on our server and managed with a private token that your browser keeps; no email or account is needed.
