Apache Spark is a multi-language engine for executing data engineering, data science, and machine learning on single-node machines or clusters.

Heron is described as 'Apache Heron (Incubating) is a realtime, distributed, fault-tolerant stream processing engine from Twitter' and is a big-data analytics tools tool in the development category. There are five alternatives to Heron for a variety of platforms, including Mac, Windows, Linux, BSD and Self-Hosted apps. The best Heron alternative is Apache Spark, which is both free and Open Source. Other great apps like Heron are ILUM, Gigasheet, Apache Flink and Apache Storm.

Flink’s core is a streaming dataflow engine that provides data distribution, communication, and fault tolerance for distributed computations over data streams.


Apache Storm is a free and open source distributed realtime computation system. Storm makes it easy to reliably process unbounded streams of data, doing for realtime processing what Hadoop did for batch processing.
