bloaty

Uses bespoke ELF, DWARF, and Mach-O parsers to accurately attribute every byte, providing more precise size analysis than standard tools like 'objdump' or 'nm'.

Combines multiple data sources such as compileunit and symbol into a single profile, offering a comprehensive view of binary composition for in-depth optimization.

Compares binary versions to pinpoint growth, ideal for integrating into CI/CD pipelines to catch and prevent size regressions, as highlighted in the README for automated testing.

Supports analyzing stripped executables using separate debug files, allowing security-hardened binaries to still be profiled without embedding debug info, a key feature for production environments.

Allows regex-based filtering and rewriting of data sources, enabling tailored analysis workflows, such as bucketing by custom patterns, as documented in the user guide.
