Last updated August 26, 2026
Overview
Aqris was an Estonian software development company based in Tallinn and founded in 1999 by Oliver Wihler and Sander Mägi. The company operated in the software-development-tools field and became associated with the Java developer community through RefactorIT, an open-source refactoring plug-in for Java integrated development environments. Refactoring tools help programmers restructure existing source code without changing its intended behavior, supporting maintainability, modernization, and the management of larger software projects. RefactorIT was notable for its broad compatibility with several Java development environments. The plug-in was available for Eclipse, Sun ONE Studio, Borland Software's JBuilder, Oracle's JDeveloper, NetBeans, and Emacs. This range positioned Aqris's principal product as an integration-oriented developer tool rather than as a standalone programming environment. Its open-source model also gave the product visibility among Java programmers and contributed to Aqris's recognition within a specialized technical community. Publicly available reference material provides limited information about Aqris's later corporate development, ownership, financial performance, management, commercial footprint, or current operations. The company is described in the past tense in the available encyclopedia material, but its present legal status cannot be established from the supplied sources. Accordingly, Aqris is best documented as a historically relevant Estonian software company and developer-tool brand, with RefactorIT as its principal known offering.
History
Aqris was founded in Tallinn, Estonia, in 1999 by Oliver Wihler and Sander Mägi. It developed software for programmers and became known particularly for RefactorIT, an open-source refactoring plug-in designed for Java development environments. The company emerged during a period in which Java was widely adopted for enterprise and cross-platform software development, creating demand for tools that could improve the structure and maintainability of Java code. RefactorIT's distinguishing characteristic was its support for multiple integrated development environments and programming workflows. The product was associated with Eclipse, Sun ONE Studio, Borland Software's JBuilder, Oracle's JDeveloper, NetBeans, and Emacs. By supporting several environments, Aqris addressed developers who used different tools while retaining a common need for source-code analysis and refactoring. The product's open-source availability also helped establish Aqris within the Java developer community. The available reference material does not document Aqris's later product releases, corporate transactions, leadership changes, financial results, or closure. It describes Aqris as an Estonian software development company located in Tallinn and uses past-tense wording, but this is not sufficient to determine a precise end date or present legal status. RefactorIT remains the principal documented association with the company.
