oxDNA vs simDRIFT
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
oxDNA combines coarse-grained DNA and RNA simulation with scriptable control and trajectory analysis. It is suited to technical users who can compile the GPL-licensed software and accept its single-device simulation limit.

simDRIFT provides configurable GPU simulations for diffusion-weighted MRI modeling and teaching. Its hardware requirements and stated modeling limits should be checked before configuring larger experiments.

- Includes Python simulation bindings
- Offers trajectory analysis utilities
- Free GPL-3.0 open source
What to know first
- Simulations run on single CPU cores or GPUs
- Monte Carlo simulations run serially
- Compilation requires CMake and C++14 g++
- Python tools specify Python 3.11 or newer
simDRIFT: what it does well
