Gazebo review
A free, desktop simulator for physics-based robotics workflows with ROS 2.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Gazebo is an open-source robotics simulator for developing, testing and validating robot systems in virtual worlds. It is aimed at robotics developers, researchers and educators who want to prototype behaviors or evaluate systems before deploying them to physical hardware. Its physics-based simulation, 3D rendering and configurable environments make it a general-purpose option for modeling both robots and their surroundings, rather than a tool focused on one robot task.
A key part of its workflow is combining simulated sensors with robot and world descriptions. Gazebo can model cameras, lidar and other sensors, while SDF describes robots and worlds. ROS 2 integration connects the simulator to robotics software workflows, and a plugin architecture allows simulation extensions. That combination suits teams building or evaluating ROS 2-based systems where sensor behavior and virtual environments matter. Buyers whose work depends on integrations beyond ROS 2 should weigh that narrower stated integration fit.
Gazebo is open-source software with a free plan, and the published product details describe local desktop deployment across Linux, macOS and Windows. This makes it a fit for individuals and organizations that want to run simulation on their own platform rather than use a vendor-hosted service. Support is described through community channels and documentation, so buyers seeking a hosted product or a different support model may prefer another option. Choose Gazebo for flexible, physics-based simulation with ROS 2; look elsewhere if hosted deployment or a broader stated integration set is central to the decision.
Gazebo pros and cons
- Where it wins
- Simulates robot physics, 3D worlds and configurable environments.
- Models cameras, lidar and other sensors in simulation.
- Combines ROS 2 integration with SDF descriptions and an extensible plugin architecture.
- Where it doesn't
- Runs locally as desktop software rather than as a hosted service.
- ROS 2 is the listed integration, so other integrations are not part of its stated fit.
- Support is through community channels and documentation.
