Ever wondered what‘s making your binary big? Bloaty will show you a size profile of the binary so you can understand what’s taking up space inside.

Bloaty performs a deep analysis of the binary. Using custom ELF, DWARF, and Mach-O parsers, Bloaty aims to accurately attribute every byte of the binary to the symbol or compileunit that produced it. It will even disassemble the binary looking for references to anonymous data.
Bloaty supports many features:
For detailed info on all of Bloaty's features, see the User Documentation.
For more information about the analysis performed by Bloaty, please see How Bloaty Works.
To build, use cmake
. For example:
$ cmake -B build -G Ninja -S . $ cmake --build build $ cmake --build build --target install
Bloaty bundles libprotobuf
, re2
, capstone
, and pkg-config
as Git submodules, and uses protoc
build from libprotobuf, but it will prefer the system's versions of those dependencies if available. All other dependencies are included as Git submodules.
If the Git repository hasn't been cloned with the --recursive
, the submodules can be checked out with:
$ git submodule update --init --recursive
To run the tests, see the info in tests/README.md.
GitHub issues and PRs welcome. Please include tests when possible, see: tests/README.md.
