In their own words
Arroyo
Arroyo is an open-source distributed engine for processing stateful computations on data streams, with sub-second results. Users build streaming pipelines in analytical SQL, including complex queries, windows and joins. Arroyo supports checkpointing for fault tolerance and recovery, exactly-once processing, and horizontal and vertical rescaling; it says the engine can handle millions of events per second. Its connectors include Kafka, Kinesis, MQTT, MySQL, Postgres, Redis, Delta Lake, HTTP and WebSocket, among others. It reads and writes JSON, Avro, Parquet, text and binary, and includes more than 300 SQL functions. Rust scalar, aggregate and asynchronous user-defined functions can extend SQL. The web UI supports connection management, query development and testing, and pipeline monitoring; pipeline management is also available through a REST API. Single-node clusters are intended for development and testing, while production deployments use a distributed cluster with Arroyo’s scheduler or Kubernetes. It is Apache 2.0 licensed, free at free, and self-hostable.
RisingWave
RisingWave is a distributed SQL platform for ingesting, transforming, and serving real-time data. Its SQL interface is wire-compatible with PostgreSQL, so PostgreSQL clients, drivers, and tools can connect. New events incrementally refresh materialized views. Barrier-based checkpointing and consistent snapshots support exactly-once processing, while data is persisted in S3-compatible object storage and connector offsets are checkpointed for delivery durability. RisingWave lists 31+ native connectors, including Kafka, PostgreSQL, MySQL, Iceberg, Snowflake, BigQuery, S3, Redis, and Elasticsearch. Self-managed deployments are Apache 2.0 open source, with Docker, Kubernetes, cloud VM, and on-premises options. The hosted Basic plan is $0.23 a month, pay-as-you-go, limited to 64 cores and available in select regions; a free plan and 7-day trial are also listed. Basic includes standard support. Premium 24x7 support can be purchased with Pro, while self-managed deployments offer premium support with an SLA and quarterly success reviews. Listed platforms include API, Linux, macOS, self-hosted, and web.
