Arroyo
Cloud-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
