Calcpad is a lightweight mathematical platform for cloud and desktop. It parses simple text scripts and converts them into professional Html reports. Supports complex numbers, variables, functions, graphing, units and numerical methods.




Very easy syntax to tap on, thus making it very convenient to do engineering calculation with units,function,plot and substitution. In a word, almost a perfect alternative for Calcpad.


Almost everyone thinks Calcpad is a great PTC Mathcad alternative.
Mathics is a general purpose computer algebra system (CAS) and designed to be a free, light-weight alternative to Mathematica. It's programmable using a Mathematica like language and uses a web interface for user interaction.

Xcos is a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated.



Valispace is a co-engineering platform that allows companies that develop complex products to bring them to market faster, helping engineers escape from document hell. It brings all loose engineering data into one central place and helps streamline engineers’ efforts from...
Valispace is the most popular SaaS alternative to PTC Mathcad.
WIRIS cas is an online platform for mathematical calculations designed for education. You can access a powerful calculation toolbar through an HTML page that includes integrals and limits calculation, function graphing in 2D or 3D and symbolic matrices manipulation, among others.



Cadabra is a computer algebra system (CAS) designed specifically for the solution of problems encountered in field theory. It has extensive functionality for tensor computer algebra, tensor polynomial simplification including multi-term symmetries, fermions and anti-commuting...
Singular is an open source computer algebra system for polynomial computations, with special emphasis on commutative and non-commutative algebra, algebraic geometry, and singularity theory.
Yet Another Computer Algebra System. There is support for numeric computations, to arbitrary precision, symbolic computation and visualization.




It supports units of measurement, vectors and matrices, but is ligthweight, free and open source.
