Unique features

  • Scalable framework developed in Scala, designed for generating reports programmatically.
  • Support of Scala, Java, other JVM languages (i.e. Groovy)
  • Pluggable architecture
  • Open Source - LGPL license - free to use and modify, for both Open Source and commercial uses
  • Displays CKJ (Chinese, Korean, Japanese) characters in PDF reports


Fit for Big data

  • Strong product for processing big data – the hard disk size is the limit
  • Designed to conserve memory; report memory data is stored on the disk, in RocksDB.
  • Built in support for Akka streams input


  • Can be integrated into CI/CD pipelines (i.e., Jenkins)
  • Reactive Reports applications can run on any JVM runtime
  • Reactive Reports applications can be Dockerized
  • Applications can integrate with other libraries, such as AI/ML, NLP and others.


  • Uses scalaz memoizing for speeding calculations
  • Generated a 20,000-page report with images in 4 minutes


  • Built in support for French and Spanish character set
  • Can build graphics using the PDF standard (tables, color gradients, pie charts, bar charts, etc.)
  • Can include external images (ie: JPG, etc)
  • Can create in document or external links, and table of contents at beginning or end of reports
  • Reactive Reports has the full control and responsibility over the PDF generation capability

Language details

  • In Java, reports are created using Java code.
  • In Scala, Reactive Reports provides a DSL - domain specific language - for report creation. This DSL is simple to use.
  • Reactive Reports can be used in Scala 2.13, 2.12 , 2.11 and in Java 7 and 8.
