## What it is
JasperReports is the world's most popular open-source Java reporting engine, capable of producing pixel-perfect documents from any kind of data source. It exports reports to a variety of formats including HTML, PDF, Excel, and more.

## Use cases
- generate pdf reports from java applications
- export reports to excel and html
- build pixel-perfect printable documents from database data
- embed a reporting engine in a java web app
- compile jrxml report templates to jasper files

## When to choose
- you need a mature, battle-tested Java reporting library with multiple export formats
- you want pixel-perfect, print-ready documents generated from any data source
- you need an open-source (LGPL) reporting engine with a large community

## When to avoid
- you need backward compatibility with version 6 or older jrxml/jasper template files without conversion
- you require 3D chart rendering, which is no longer supported in JFreeChart 1.5.4
- you want a lightweight reporting solution without JVM dependencies

## Facets
- artifact type: library
- maturity: active
- function: pdf, data-visualization, templating
- domain: pdf, data-visualization, developer-tools
- platform: jvm
