I have an in-house C++ FVM code. I want to know some open-source AMR-based grid generators to link to my FVM solver. Thanks.

Greetings
I found Salome a nice open-source software.
It is an open-source software platform for numerical simulation and 3D modeling, specifically for creating finite element meshes. It includes various tools for geometry creation and editing and mesh generation. Salome is often used in conjunction with the Code_Aster finite element analysis software but can also be used with other simulation codes. The software is available for Windows, Linux, and Mac operating systems.
Salome supports AMR through the NETGEN meshing library, which has AMR capabilities. To use AMR in Salome, you would typically follow these steps:
1- Import or create the geometry of the model in Salome.
2- Use the NETGEN mesher in Salome to create a coarse mesh of the geometry
3- Define the regions where you want to apply the AMR. These regions can be defined by geometry entities or user-defined criteria such as element quality, curvature, or gradient of a field variable.
4- Use the AMR capabilities of the NETGEN mesher to refine the mesh in the defined regions, creating a more detailed mesh in those areas.
5- Export the mesh in a format that can be read in your flow solver
In the end, it is important to note that if you need mesh for CFD software and you need prism layer mesh, Salome limits you to Tetrahedral mesh.

Thanks Alireza Aslani for the detailed description about Salome. Will take a look at it.
