Suggestion to add SourceWeb

http://rprichard.github.io/sourceweb/

SourceWeb is a C/C++ code indexer and a code navigator GUI.

The indexer uses Clang's libraries to parse translation units. The output is a binary index file, optimized for fast creation, fast lookup, and small size. It generally indexes a project in about the same amount of time needed to build it. The input to the indexer is a compile_commands.json file listing all of the command lines that compile a source file to an object file.
