Recast Navigation is an industry-standard C++ toolset for generating navigation meshes from level geometry and performing runtime pathfinding, with modules for navmesh streaming and crowd simulation. It is dependency-free, requiring only a C++98-compliant compiler, and powers AI navigation in Unity, Unreal, Godot, and many games.

Use cases

• generate a navmesh from arbitrary level geometry
• pathfinding for game AI agents
• crowd simulation with collision avoidance
• stream tiled navmeshes for open-world games
• integrate navigation into a custom game engine
• debug and visualize navigation data

When to choose

• you need battle-tested navmesh generation and pathfinding in C++
• you want a dependency-free library that builds anywhere
• you need tiled navmeshes or crowd simulation for large worlds
• you want the same navigation tech used by major engines

When to avoid

• you need a high-level out-of-the-box solution rather than a C++ library to integrate
• your project is not C/C++ and you cannot bind to native code
• you only need simple grid-based movement without navmesh complexity
