GroIMP is a Java-based, open-source modelling platform for functional structural plant modelling. It includes the integrated XL modelling language, a 3D object library, data interfaces and a plugin system. The site also provides GROGRA, an L-system interpreter, and XL4C4D, an XL plugin for CINEMA 4D. GroIMP runs on Windows, Linux and macOS and is free to use.

The software is aimed at researchers and modellers working with growth grammars and plant modelling. The community shares models through a gallery and a YouTube channel, and offers a wiki, manuals and e-learning resources. Users can add functionality through plugins installed from within GroIMP. The project is primarily developed at the Department of Ecoinformatics, Biometrics and Forest Growth at the Georg-August University of Göttingen, with cooperation partners. Development is hosted on a GitLab group, and the community is connected on Slack.

The site is the web centre for growth grammars at the Göttingen department. It also lists the growth-grammar publications and the FSPM field the software serves. The project aims to hold annual workshops.
