Desmos vs GeoGebra
Both sit in Mathematics on the Edibok index. Here is what each one is, side by side, so you can tell which fits the job you actually have.
| Desmos | GeoGebra | |
|---|---|---|
| Tagline | A graphing calculator that became a playground, plus free classroom activities students argue about. | Dynamic geometry, algebra, 3D, and a million ready made applets: the Swiss Army knife of math visualization. |
| Grade bands | 6-8 · 9-12 | 6-8 · 9-12 |
| Price model | Free | Free |
| Platforms | Web · iOS · Android | Web · iOS · Android · Windows · Mac |
| Notable features | Live teacher view; Anonymize mode; Free forever calculator | 3D graphing; Huge applet library; Works offline |
| Privacy and accounts | Minimal student data, clear education privacy policy. A district staple. | Open, nonprofit backed platform; no student accounts required for most uses. |
Desmos
What started as a free graphing calculator grew into one of the finest pedagogical tools ever put on the web. Desmos Classroom activities let students conjecture, sketch, and react to each other in real time while you watch every screen from the teacher view and pause the room with one click.
Run Marbleslides on a Friday and watch students beg to finish a linear equations task.
GeoGebra
An open ecosystem for interactive mathematics. Drag a vertex and watch the proof survive, spin a solid in 3D, or pull one of the community's countless prebuilt applets straight into your lesson. It is the rare tool that spans middle school geometry through university calculus.
Search the resource library before you build anything: someone has almost always made your applet already.
