The LSE Directory / Charting platforms
Cheddar Flow is a web-based options order flow platform built for retail traders in the US equity options market. Its core product is a real-time scanner that surfaces large call and put orders as they print, color-codes them by side and order type (including intermarket sweep orders), and layers on dark pool block-trade prints so users can see where large, off-exchange volume is landing. The platform also includes historical flow data for backtesting, a put/call sentiment and ratio view, watchlist-based AI alerts, and integrated charting. The company targets self-directed retail options traders rather than institutions, positioning the product as a way to follow "smart money" positioning without the cost of an institutional data terminal. It competes in a small niche of retail order-flow scanners alongside names like Unusual Whales, FlowAlgo and BlackBox Stocks; its differentiation is chiefly around interface design, an on-demand historical/backtesting archive, and tiered subscription pricing (reported around 85 to 99 dollars a month, with an annual option, plus a free trial) rather than a distinct data source, since retail flow scanners in this category generally license the same underlying exchange tape. Cheddar Flow was founded in 2018 by Blaze Kuklinski, a San Francisco-based founder with prior experience at companies including Square and Weebly, and the company remains headquartered in San Francisco. Independent company-data sources (Crunchbase and Tracxn) list it as a small, unfunded company, with Tracxn citing roughly 6 employees as of an April 2026 snapshot. It has not disclosed any external funding rounds, revenue, or assets-under-management figures, consistent with its positioning as a bootstrapped retail data-tools business rather than an institutional platform.
