- [Launching Today: Free Wolfram Engine for Developers By Stephen Wolfram. At https://writings.stephenwolfram.com/2019/05/launching-today-free-wolfram-engine-for-developers/ ]
- Wolfram Engine
- Lets you run WolframLang code. It also comes with WolframScript.
- WolframScript
- A command line interface to Wolfram Engine. Runs in terminal. [see WolframScript Tutorial]
- Mathematica
- Is roughly Wolfram Engine plus Wolfram Notebook interface.
Wolfram Engine does not render Graphics output or typeset math formulas. If you want graphics, either buy Mathematica, or install and configure Wolfram Language kernel for Jupyter notebooks https://github.com/WolframResearch/WolframLanguageForJupyter
Wolfram Engine is Bundled with Raspberry Pi

Buy Mathematica
Or, just buy it. Cheap for student or hobbist. I recommend it as life time investment. https://www.wolfram.com/mathematica/pricing/
