What users praise
- • Visual builder removes boilerplate and makes environment prototyping fast.
- • Versioning with rollback protects experiments and enables clean iteration.
- • Built-in agents allow immediate validation of environments before full runs.
What frustrates them
- • Lacks multi-agent support, limiting its use for complex scenarios.
- • No advanced physics simulation; not a substitute for MuJoCo or Isaac Gym.
- • Not a training platform; users must pair it with an external framework.
