GeoGebra is free math software combining graphing, geometry, CAS, and 3D tools. Available on web, Windows, macOS, Linux, iOS, and Android.
GeoGebra is a suite of interactive mathematics applications originally created in 2001 by Markus Hohenwarter as part of his master's thesis at the University of Salzburg. It is now developed under the nonprofit International GeoGebra Institute, headquartered in Linz, Austria, with a global network of more than 140 user groups.
The software combines geometry, algebra, calculus, and statistics into a single interactive environment, making it widely used in math education from secondary school through university level.
GeoGebra includes a Graphing Calculator for 2D functions, a Geometry app for constructions, a 3D Calculator, a CAS Calculator for symbolic math, and a Scientific Calculator with fraction and statistics support.
It also offers a Math Solver for step-by-step homework help, GeoGebra Notes for collaborative documentation, and GeoGebra Classroom, which lets teachers monitor and guide student work live during a lesson.
All GeoGebra apps and Classroom features are free for personal, educational, and non-commercial use, with no subscription or trial period required.
Organizations that want to use GeoGebra for commercial purposes, such as creating paid educational materials or running a commercial online school, need a separate commercial license, priced individually based on the organization's needs rather than through a published rate.
