Code::Blocks
What it is
Code::Blocks is a free IDE for C, C++, and Fortran on Linux, macOS, and Windows. Its editor provides syntax highlighting, code folding, tabs, code completion, a class browser, and smart indentation. A custom build system supports parallel builds, multi-target projects, workspaces, and inter-project dependencies. Listed compiler support includes GCC, MSVC++, clang, Digital Mars, Borland C++ 5.5, and Open Watcom. The debugger interfaces with GNU GDB and supports MS CDB, which the site describes as not fully featured. Projects can be imported from MSVC and Dev-C++; assembly code is not supported in MSVC imports. A plugin framework allows installed or user-written extensions. Code::Blocks uses GNU GPL version 3, while its SDK uses GNU LGPL version 3. The site provides a manual, wiki, and forums for help.
