ctseg vs exaDEM
Both stand on physics simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacSelf-hosted
ctseg provides a focused solver for supported quantum-impurity interaction models and measurements. Its single-orbital spin-spin restriction is important when planning multi-orbital calculations.

ctseg: what it does well
- Free software with offline access
- Supports retarded density-density interactions
- Measures multiple Green’s-function observables
- Docker and package installation options
- Self-hosted deployment is available
What to know first
- Spin-spin expansion supports one orbital only
- Multiple orbitals restrict expansion choices
- Source builds require matching TRIQS versions
exaDEM: what it does well
- Free software with Apache-2.0 license
- Supports spherical particles and spheropolyhedra
- MPI, OpenMP, and CUDA GPU support
