Coinalyze

What it is

The whole crypto futures market as one sortable table. Every coin gets a row; the columns are price, 24-hour change, market cap, volume, open interest, open-interest change and share, the ratio of open interest to volume, average funding, average predicted funding and 24-hour liquidations. Above it sit filters, a column picker, watchlists and a custom-metrics builder; below it, per-coin pages for open interest, funding rate, liquidations, long/short ratio and basis, plus per-contract charts for every individual instrument on every venue.

That is the entire product and the reason to use it. Other screeners sell a view of one metric; this one sells the comparison across all of them, and it does not put a login in front of any of it.

There is no changelog and the blog stopped in 2022, so this card takes the unusual step of saying how it knows the product is alive — see the coverage section, where the evidence is dated.

Pricing

Free, in the sense that almost nothing is held back. Alerts, watchlists, custom metrics, the full contract listing, every per-coin chart and the API are all on the free tier.

The single paid product is an Ad-Free Version at $10.95 a month, and the vendor is honest about what it is: more space, a cleaner layout, faster browsing, no disruption, no tracking by ad networks. It removes advertising. It does not unlock data, history, venues or timeframes. The free site loads third-party ad scripts, and the subscription is the way to stop them.

No annual price is published, and the subscribe control needs an account.

Data & coverage

Sixteen venues on the individual-contracts listing — Binance, Bybit, OKX, Gate.io, Huobi, Kraken, Deribit, Bitfinex, Phemex, WOO X, Coinbase, dYdX, Hyperliquid, Aster, Lighter and Polymarket. Coverage is by contract rather than by coin, so you get the quarterly and bi-quarterly expiries and the coin-margined and stablecoin-margined pairs separately rather than folded into one aggregate.

The dated evidence that this is maintained is that four of those sixteen are new. The Internet Archive's capture of the same listing from 23 May 2025 contains no Aster, no Lighter, no Polymarket and no Coinbase contracts; the live page carries 1,644 Aster entries, 588 Lighter, 192 Coinbase and 164 Polymarket. Separately, the site versions its own asset bundles with an incrementing counter, and that counter reads 328 in the January 2025 capture, 342 in December 2025, 348 in January 2026 and 349 today. It is indirect and it is slow, but it is dated, and it is what there is.

Tokenized equity and commodity derivatives sit in the same table. SanDisk, Alphabet and gold appear as coins would, marked "(Derivatives)", which is worth knowing before you read a total off the top of the table.

Aggregated coin charts are not real-time, by the site's own notice: the per-coin aggregated charts say so and point at the Markets page for live figures. The distinction is not visible from the chart itself.

Integrations

A free REST API at 40 calls a minute per key, twelve endpoints — supported exchanges, future markets, spot markets, current and historical open interest, current, predicted and historical funding rate, liquidation history, long/short ratio history and OHLCV history. A missing key returns 401 and going over the limit returns 429 with a Retry-After header. The key comes from an ordinary account.

Retention is the thing to read before building on it. The documentation states that between 1,500 and 2,000 datapoints are kept for any intraday granularity from one minute to twelve hours, and that the old data is deleted each day. Daily bars are not deleted. So the API is a live feed with a short rolling window, not an archive: at one-minute granularity that is somewhere between 25 and 33 hours of history, permanently.

The documentation also asks, rather than requires, that public use of the data cite the source.

Limitations

• Intraday history through the API is a rolling window of 1,500 to 2,000 points, deleted daily. Anything that needs a year of minute bars needs a different provider, and no paid tier here fixes it.
• Paying changes nothing except the advertising. $10.95 a month buys layout, not data. That is refreshingly clear, and it also means the free version is the product you are evaluating.
• The aggregated coin charts lag, by the vendor's own notice, with live figures only on the markets page.
• No changelog, and the blog has been silent since 2022. There is no vendor-published record of what shipped or when, which is why this card had to date the product from venue coverage and asset versions instead.
• The site is behind a challenge that blocks automation. Ordinary browsers get through; command-line tools and headless browsers get a 403. That matters if you intended to scrape the tables rather than use the API, and it is the reason the API's retention limit is the real constraint.
• No options anywhere. Futures and perpetuals only. Open interest, funding, basis and liquidations — no strikes, no Greeks, no max pain.
• No mobile app. Web only. The similarly-named app in the App Store is from an unrelated publisher.
• Nothing is published about who runs it. No company behind the brand is named on the pages used for this card, which is worth weighing before making it a dependency.

Alternatives

The other free derivatives screeners in this category carry more of the visual products — the liquidation heatmaps, the order-flow footprint, the rankmaps — and gate part of them. Coinalyze carries fewer of those and gates none. If the job is comparing a hundred contracts on one screen and then charting one of them, this is the cheaper and plainer answer; if it is reading a liquidation heatmap, it is the wrong one. The rest are under crypto charting platforms.
