A command-line tool that aggregates Clang -ftime-trace JSON reports across a whole C/C++ build and summarizes what took the most compile time. It reports slowest files to parse, template instantiation costs, codegen hotspots, and header include statistics.

Use cases

• find which source files are slowest to compile
• identify expensive C++ template instantiations
• analyze header include chains and parsing time
• aggregate clang ftime-trace reports across a build
• speed up C++ build times
• find functions with slow codegen and optimization

When to choose

• you build C/C++ with Clang 9+ and want to reduce compile times
• you need project-wide aggregation of -ftime-trace data
• you want to find slow headers or template instantiation bottlenecks

When to avoid

• your build uses GCC or MSVC rather than Clang
• you need per-file interactive flame charts instead of aggregate summaries
• you are profiling runtime performance rather than compile time
