Bullflow
bullflow.io
Real-time unusual options flow with a SigScore ranking, GEX and vanna levels, and dark pool prints on the higher tier, from $39 a month with no free plan.
What it is
Bullflow is a real-time options flow scanner built around filters, algorithmic alerts and gamma exposure (GEX) charts. Each trade gets a proprietary SigScore that ranks how unusual it is, and the historical flow view shows how past alerts performed, including their peak return, so you can check whether a kind of alert has been worth following.
There are three paid plans and no free tier or trial. Basic covers real-time and historical flow, SPX and VIX index flow, GEX levels, the options heat map, AI trade signals, alerts and the Discord. Premium adds the Bullflow Terminal (a customizable multi-window workspace), real-time and historical dark pool trades with alerts, vanna exposure, GEX heatmap replay and faster GEX updates. The Data API plan includes Premium plus API keys, a backtesting endpoint and an MCP server for coding agents, under a personal-use licence.
Annual billing lowers the price by about 14 to 23 percent depending on the plan. Cancellation is from the dashboard and access runs to the end of the billing period. The web app, iOS and Android apps are included in every plan, and trades can be placed from the dashboard through an integration with the broker Public.
