Alternatives to Desmos
Free online graphing, scientific, geometry and 3D calculators, plus a math notebook. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
Desmos
Free online graphing, scientific, geometry and 3D calculators, plus a math notebook.
Replacements
Listings that take over the same core job as Desmos.
GeoGebra
Free interactive math tools for graphing, geometry, 3D, algebra and calculus, used in browsers and apps.
GeoGebra is also free and browser-based, adding Android and iOS apps, dynamic geometry constructions and a large classroom resource library, though its many apps can confuse.
Wolfram|Alpha
A computational knowledge engine that answers math, science and everyday questions typed in plain language.
Wolfram|Alpha answers plain-language math and science questions with step-by-step solutions, but some features are paid and it is less of an interactive graphing tool.
Symbolab
An online math solver that works through algebra, trigonometry and calculus problems step by step.
Symbolab adds step-by-step solutions alongside graphing calculators, available on web, mobile and as a Chrome extension, with some features behind a Pro subscription.
SageMath
A free open-source mathematics system built on NumPy, SciPy, Maxima, GAP and many other packages.
SageMath is free, open-source GPL software for Windows, macOS and Linux offering full computer algebra through a Python-based language, with a large install and learning curve.
Kig
A KDE interactive geometry program for building and exploring geometric constructions with the mouse.
Kig is a free, open-source KDE desktop geometry program for macOS and Linux with live constructions and Python scripting, but it lacks function graphing and 3D calculators.
Also worth comparing
These listings name Desmos as their own alternative, so the relationship runs both ways.
PhET Interactive Simulations
Free interactive physics, chemistry and math simulations usable directly in the browser.
Desmos gives free graphing, geometry and 3D calculators in the browser, focused on math exploration rather than physics and chemistry simulations.
Photomath
A mobile app that scans math problems with the camera and explains the solution step by step.
Desmos is a free browser-based set of graphing, scientific and geometry calculators, but it does not scan problems or give step-by-step explanations.
Similar software
Related functionality, not a direct replacement.
Mathway
A math problem solver that shows step-by-step solutions for typed or photographed problems.
Brilliant
Interactive, visual lessons and an AI tutor for learning math and coding, on the web and mobile.
fend
An arbitrary-precision calculator for the terminal that understands units and converts between them.
Numbat
Calculate with physical units in a typed scientific language.
Veusz
A scientific plotting package that produces publication-ready PDF and SVG figures, built by combining plotting widgets.
