Open Source Software

Esri continues to make significant technical and financial contributions to open source software events, libraries, tools, and apps. Esri employees have developed over 500 open source projects onĀ GitHub, most of them licensed under Apache 2.0; regularly contribute to third-party projects like GDAL; and attend FOSS4G conferences.

Open source spotlight

Esri development staff are encouraged to engage with the open-source community. Developers regularly share open source projects via GitHub to enable developers and partners to port Esri capabilities across the web. Esri welcomes more interactions with developers on this forum.
