StormCrawler is modular and consists of a core module, which provides the basic building blocks of a web crawler such as fetching, parsing, URL filtering. Apart from the core components, the project also provide external resources, like for instance spout and bolts for Elasticsearch and Apache Solr or a ParserBolt which uses Apache Tika to parse various document formats.

The project is used in production by various companies.[1] published a Q&A in October 2016 with the author of StormCrawler.[2] InfoQ ran one in December 2016.[3] A comparative benchmark with Apache Nutch was published in January 2017 on[4]

Several research papers mentioned the use of StormCrawler in 2018, in particular:

  • The generation of a multi-million page corpus for the Persian language.[5]
  • The SIREN - Security Information Retrieval and Extraction eNgine.[6]

The project WIKI contains a list of videos and slides available online.[7]

StormCrawler is used notably by Common_Crawl [8] for generating a large and publicly available dataset of news.
