# What is jSparrow?
jSparrow is an IDE extension for refactoring Java code with a rule-based approach, powered by the Eclipse Java compiler. A jSparrow rule is a definition of many small composed refactoring steps performed by the plug-in; one rule, when selected, can by itself refactor a very specific area within your system-wide code.
Additionally jSparrow now also offers markers that will allow you live and in-depth guidance towards best practice java while you are programming.
Refactor your Java code. Improve the code quality. Apply the latest Java features.
jSparrow is in active development and there are new rules released regularly. The latest changes are always linked in the Latest Release Notes!
