| Installation | The project README gives `pip install fenics-basix` as the PyPI installation command. | The maker provides a pip installation command and an editable installation path for development. |
| Intended users | The project describes FEniCS as a platform for solving partial differential equations with the finite element method, with Python and C++ interfaces for users ranging from beginners to experienced programmers. | The project describes FDTDX as freely usable for research, development, and commercial work involving photonic nanostructures. |
| Purpose | Basix is a finite element definition and tabulation runtime library. | FDTDX is an open-source Python package for simulating and designing three-dimensional photonic nanostructures with the Finite-Difference Time-Domain method. |
| Support | Users can report bugs through the GitHub issue tracker and ask usage questions on the FEniCS discourse group. | The FAQ invites users to open GitHub discussions for unanswered questions and issues for suspected bugs, and says the maintainers regularly check discussions. |
