CoinGlass vs Coinalyze: only one paid tier unlocks any data

Two free screens, and the paid tiers point in opposite directions

A perp trader with both tabs open is usually reading the same three things on each: open interest, funding and liquidations. Both products show all three free and without an account. The useful difference is not on the free screens. It is in what money buys at each vendor, and the two answers point in opposite directions.

Coinalyze gives away everything it has. That covers alerts, watchlists, the custom-metrics builder, every per-coin and per-contract chart, and the API. Its one paid product is an Ad-Free Version at 10.95 dollars a month, and the vendor says plainly that it removes advertising and nothing else. There is no annual price.

CoinGlass gives away almost everything except the thing it is known for. Prime is 28 dollars a month, 78 a quarter or 268 a year (about 22.33 a month on the annual plan). In the vendor's own FAQ, it buys one feature made whole: the liquidation heatmap for all coins rather than BTC and ETH, a 24-month-plus range on top of 6 and 12 months, and automatic refresh. It is web only, since the vendor says the apps do not get it yet, and it is non-refundable.

So the free versions are the comparison. Coinalyze's paid tier cannot change your answer, and CoinGlass's changes it only if the heatmap was the question.

What each one is actually aggregating

Coinalyze is one table, by contract. Every coin gets a row with price, volume, open interest, open-interest change and share, the ratio of open interest to volume, average funding, average predicted funding and 24-hour liquidations. Behind the rows are sixteen named venues: Binance, Bybit, OKX, Gate.io, Huobi, Kraken, Deribit, Bitfinex, Phemex, WOO X, Coinbase, dYdX, Hyperliquid, Aster, Lighter and Polymarket. Quarterly expiries and coin-margined and stablecoin-margined pairs are kept apart, not folded into one figure. Futures and perpetuals only, with no options anywhere.

CoinGlass is a set of pages, plus an options desk. Funding, open interest, long/short, liquidation history, three heatmap models and a liquidation map, Bitcoin exchange balances, ETF flows and an exchange ranking. It also has the one thing Coinalyze does not touch: options, with open interest by strike and expiry, max pain and an Option Greeks table for BTC and ETH on Deribit. The web card publishes no venue list. It says only that the terminal covers the large futures venues. The thirty futures venues on the CoinGlass API card are the API's list, and neither CoinGlass card says the web terminal aggregates the same thirty. One of the thirty, BitMEX, ceased trading on 23 September 2026.

Both tables now carry non-crypto rows. Coinalyze lists SanDisk, Alphabet and gold marked "(Derivatives)". CoinGlass carries SNDK, SPCX, SKHYNIX and XAU beside the coins. A total read off the top of either table may include them.

The headline numbers are not proven to be the same number

This is the gap a reader should know about before laying one site's figure next to the other's. Neither card records whether open interest is shown in coins or in dollars. Neither records what period funding is normalised to. And the Coinalyze card does not say how its "average funding" across venues is weighted. The only stated method on the CoinGlass side is about its API: open interest and funding come as candles, with stablecoin-margined and coin-margined contracts reported separately. Whether the web pages follow the same convention is not on the card.

With different venue sets as well, a gap between the two sites' figures for one coin is not evidence that either is wrong. Find out which units and venues each figure uses before reading anything into the difference.

Liquidations: a record on both, an estimate on one

Both sites record liquidations that happened. Coinalyze shows them as a 24-hour column, per-coin pages and a liquidation-history endpoint; CoinGlass as liquidation history and top liquidation events. Neither card says which venue feeds those totals are built from.

The heatmap is a different kind of number, and only CoinGlass has one. It shows levels where positions would be liquidated, not liquidations that occurred. The API documentation quoted on the CoinGlass API card describes the levels as "calculated based on market data and liquidation leverage levels". The two cards record the same caveats:

• Three models, no published difference. The web catalogue lists Liquidation Heatmap, Model 2 and Model 3. The API docs describe model1, model2 and model3 in identical words. Neither says which model the default web chart draws, so a level you quote from a screenshot is a level you cannot fully explain.
• The free heatmap is two assets. BTC and ETH, 6 and 12 months, and it does not refresh by itself. An altcoin heatmap you saw in a screenshot is the paid view.
• Prime does not carry over to the API. The heatmap endpoints in the API start at the Professional plan, 879 dollars a month, three tiers above the cheapest key.

Coinalyze's own card says it plainly: if the job is reading a liquidation heatmap, Coinalyze is the wrong tool.

Refresh, alerts and getting the numbers out

Refresh. Both cards record the data as real-time, and both name an exception. Coinalyze's aggregated coin charts carry the site's own notice that they are not real-time, and point to the Markets page for live figures. The chart itself gives no sign of this. On CoinGlass, the free heatmap has to be reloaded by hand; auto-refresh is the third thing Prime sells. On the API side, CoinGlass states that freshness is the same on every plan, within a minute, with each endpoint's own cache interval. The Coinalyze card records no refresh interval for its API.

Alerts. Coinalyze's alerts are on the free tier. On CoinGlass, the alert surface the card describes is a public real-time feed of open-interest anomalies, not alerts you configure. Neither product has webhooks.

Programmatic access. This is where the pair splits most clearly.

• Coinalyze: free, 40 calls a minute per key, twelve endpoints covering open interest, current and predicted funding, liquidation history, long/short and OHLCV. Retention is 1,500 to 2,000 points at every intraday granularity from one minute to twelve hours, deleted daily, and daily bars are kept indefinitely. The site itself blocks command-line tools and headless browsers, so the API is the only automated route. The docs ask, rather than require, that public use cite the source.
• CoinGlass: nothing with Prime. The cheapest key is Hobbyist at 35 dollars a month (the pricing page's 29 is the annual rate). It allows 30 calls a minute, personal use only, and nothing finer than a four-hour bar. Minute bars, WebSockets and commercial use start at Standard, 379 a month.

Worked through from the stated retention, the free window is not as short as it first looks. At one-minute bars Coinalyze keeps 25 to 33 hours. At four-hour bars the same 1,500 to 2,000 points come to roughly 250 to 330 days. Hobbyist's four-hour history is 180 days. What CoinGlass's paid ladder sells over that is breadth (thirty venues, heatmaps, order flow, options aggregates) and licensing. A longer four-hour history than Coinalyze keeps for free starts at Standard, not at the cheapest key. Both are per-minute limits, so they compare directly here. For APIs metered in other units, see why API quotas don't compare.

Why there is no third card here

Two other screeners in the category came up and were left out, because neither adds a reason to this decision.

CoinAnk covers the same funding, open-interest and liquidation ground. What it charges for is order-flow footprint and volume profiles, and its own card says to compare that against dedicated footprint tools. Its VIP price is not published on its website. Part of the site also issues trading calls, which the card flags.

Hyblock Capital sells its liquidation heatmap from the Advanced plan at 99 dollars a month. It is built for ranking the whole market by order-book metrics, which is a different buyer.

Anyone who simply wants an altcoin liquidation heatmap has the cheapest priced option in CoinGlass Prime.

How old these facts are

All three cards behind this page had their pricing, capabilities and coverage verified on the same day, 19 September 2026, three weeks before this page was written. Nothing here rests on two readings taken months apart. The CoinGlass API card was edited on 4 October to record the BitMEX shutdown, but its verification date did not move. Its live venue list behind a key was not re-checked. Coinalyze publishes no changelog and its blog stopped in 2022. Its card dates the product as live from venue additions and asset version numbers instead, and no company behind the brand is named.

Which one, and when

Start with Coinalyze if the job is comparing many contracts across venues on one screen, or pulling funding, open interest and liquidations into your own code without paying. Its free tier is the whole product. Do not pay the 10.95 dollars expecting data.

Switch to CoinGlass the moment the question is a heatmap or an option. Coinalyze has neither, and no tier there adds them. Stay on the free CoinGlass for BTC and ETH. Pay 28 dollars for Prime only if you need altcoin heatmaps in a browser, and only once you accept that the three models are undocumented and that Prime buys no API access.

If the heatmap has to reach your own code, neither of these screens is the purchase. That is the CoinGlass API at the Professional plan, 879 dollars a month. Price it as a separate decision.

Neither screen, and no tier of either, tells you where price is going. Both describe positioning after the fact, and the heatmap is an estimate of where forced closes would happen.
