Arroyo
AcquiredCloud-native stream processing
About
Arroyo is a serverless stream processing platform built on top of the open-source Arroyo streaming engine. We allow companies to transform, filter, aggregate, and join their Kafka streams in real-time just by writing SQL. We charge purely based on usage, with no fixed costs or clusters to manage. In 2025, Arroyo was acquired by Cloudflare and now powers Cloudflare Pipelines

Launch
Build real-time data pipelines in SQL without a real-time platform team
Arroyo builds real-time data pipelines from Kafka by allowing SQL-based streaming queries (filter, aggregate, window, join) with sub-second results. It fully manages infrastructure, autoscale based on data, and charges based on usage with no minimums; targeted at teams needing real-time data processing without managing a real-time platform.
