What to use instead of Unusual Whales

The product

We list Unusual Whales ourselves, and its card is the full account of it: both price ladders, the API, coverage and limits, verified in September 2026. Its retail and API prices were re-read on the vendor's own pages on 9 October 2026 and had not moved; what had changed was the free account, which the pricing page now shows with options flow two trading days behind rather than 15 minutes, and the card has been corrected. This page does not replace the card. It answers the narrower question an Unusual Whales user asks once the bill or one of its limits comes up: what else does this job, and what does the switch cost.

Unusual Whales is an options-tape vendor with a retail front end on top. The data is the product: every US option print carrying sweep, block and multi-leg markers, dark pool prints, per-strike gamma and Greek exposure, and disclosure feeds — congressional trades, Form 4 insider transactions, 13F institutional holdings — from one REST API with WebSocket channels alongside, and a web dashboard with phone apps. It is sold as two products that do not include each other. The dashboard is Retail Basic at 50 dollars a month, Retail Pro at 75 and Retail Max at 120. The API is 150 a month for Basic, with a two-year lookback, and 375 for Advanced, which adds CME futures and the premium endpoints. Business plans, the only ones with commercial licensing, start at 625 a month billed annually.

Options flow here is a record of prints, and this page treats it that way. What a print means for a trade is not something this catalogue says, of this vendor or of any pick below.

The reasons a holder looks elsewhere:

• Two bills for one habit. Someone who wants the screen and a key pays for both: Retail Pro plus API Basic is 225 a month.
• History starts in 2022. The options tape begins on 1 January 2022, and a plan's lookback window, not the archive, decides how much of it a key can reach.
• The data is for personal use. The API page read on 9 October 2026 says redistribution is not allowed; anything shipped to other people needs a business plan.
• The framing. The dashboard is sold on alerts, unusual-activity flags and an AI analyst, and the vendor's own published agent skill emits per-ticker verdicts. Some readers want the prints without that layer.

What to use instead

For the nearest competitor head to head, Unusual Whales vs Quant Data goes further than this page; the prices match almost to the cent, so the contents decide.

If what you use is the flow dashboard. Quant Data is the same shape: a 74.99 dashboard with phone apps, a separate 149.99 API with an MCP server, dealer Greek exposure and dark pool prints. Its tape comes both consolidated and one row per exchange leg, and its sentiment label is a published rule on side of the quote. OptionStrat reassembles prints into labelled orders on its 99.99 Live Flow plan and puts congressional and Form 4 feeds in the same screen, beside a strategy builder; it has no API, and anyone OPRA classes as a professional cannot buy its live data.

If what you use is the exposure chart. Volland rebuilds dealer exposure strike by strike from classified OPRA trades rather than from open interest, with per-strike charts from its 150-dollar Swing plan. The dealer side is an inference from trades the feed does not label, and its card says so.

If what you use is chain analytics. Market Chameleon is earnings-move history, IV rankings, unusual volume and strategy screeners in a browser, at 99 a month on 15-minute delayed data, with no API.

If what you use is the congressional feed. Quiver Quantitative sells it over REST from 30 a month, with Form 4 and 13F from 75. Capitol Trades shows three rolling years of it free, without an account, and lets none of it out. The how-to getting congressional trades as data covers what breaks when you build the same feed from the House and Senate filings yourself.

If what you want is the raw data. ORATS sells cleaned chains with smoothed implied volatility and greeks back to 2007 from 199 a month; Cboe DataShop sells OPRA history from January 2012 one file at a time; Massive sells the tape as raw data with no flow layer and no disclosure feeds. None of them labels a print a sweep or a whale; any such label is yours to compute. The options data collection lists the rest.

What you give up

Flow, exposure and filings under one key. One Unusual Whales API key returns option prints, dark pool prints, Greek exposure, congressional trades, Form 4 and 13F. Splitting the job means Quant Data for the flow and Quiver for the filings, two keys and two bills, and Quiver's published tiers forbid commercial use.

Bulk days of the tape inside the lookback. Unusual Whales serves a whole day of the tape as one CSV through the API, within the plan's window. Quant Data keeps about a year and is pulled by polling at 240 requests a minute; OptionStrat and Market Chameleon have no API; a full day from Cboe DataShop is 132 dollars a file.

Streaming at the 375 tier. WebSocket streaming of option trades is on API Advanced. Quant Data documents no streaming endpoint at any price.

The labels you were used to. Sweep, block and unusual flags are each vendor's own grouping of the same prints. Moving to another vendor, the same minute of tape can come out as one sweep or as four trades, and a quick look at the two side by side is the only way to see how far apart they are.

Migration notes

Pull the history you need before the key lapses. Lookback is a property of the plan, not the archive: a date outside it returns 403. Bulk-download the days you will want while the plan that reaches them is active.

Do not expect labels to reconcile. Diff counts of prints, not counts of sweeps. Prints come from OPRA and should agree between vendors for the same contract and minute; groupings into orders, and any bullish or bearish tag, will not. The order flow and OPRA entries explain why.

Check your OPRA status before buying anywhere. Quant Data's API returns an error until you sign the OPRA subscriber agreement, its published API plan is non-professional only, and OptionStrat refuses live data to professionals outright. A professional subscriber should ask each vendor before paying.

Redistribution changes the price, everywhere. Unusual Whales, Quiver, Volland, OptionStrat and Cboe DataShop all restrict passing their data on; what is fine in a notebook is not fine in an app.
