Unusual Whales vs WhaleWisdom
Trying to decide between Unusual Whales and WhaleWisdom? Here's how they compare on pricing, features, and platforms — and which one fits the way you invest.
Unusual Whales
Best for options & derivatives and money flow
Options-order-flow and market-activity platform focused on US equities/options: real-time options flow + dark pool/off-exchange feeds, alerts (free vs premium speed), screeners, news, congressional trading, mobile apps, and a developer API. Pricing FAQ lists one subscription tier at $48/mo or $528/yr; the official API docs expose REST, WebSocket, Kafka and MCP access paths, with WebSocket streaming gated to the API Advanced plan and historical full-market option trades sold separately.
WhaleWisdom
Best for institutional data and 13f
Aggregates 13F filings, Schedule 13D/G data, Form 4 insider activity, and institutional ownership tools so investors can follow fund positioning, build watchlists/filer groups, export data, and backtest crowding strategies. Free access remains available with limited tools and recent 13F history; the pricing page says there are no trial accounts, while much of the site can be explored for free. Current paid plans are Standard at $90/quarter or $300/year, Pro at $150/quarter or $500/year, and Enterprise by quote for team access, unlimited 13F API access, live data feed calls, and nightly FTP files.

The real difference is focus: only Unusual Whales gives you options & derivatives and money flow, and only WhaleWisdom gives you institutional data and 13f.
