## Choose when

### Choose habitat-sim if…

- License: habitat-sim is MIT, AirSim is Other.
- Tags unique to habitat-sim: c++, cplusplus, robotics, sim2real.
- Leaner open-issue backlog (269).

### Choose AirSim if…

- License: AirSim is Other, habitat-sim is MIT.
- Tags unique to AirSim: airsim, artificial-intelligence, autonomous-quadcoptor, autonomous-vehicles.
- Also covers AI Agents.

## When NOT to use AirSim

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
