Where it wins
- Displays DWARF, CTF, and BTF data-structure layouts
- Inspects offsets, sizes, padding, and alignment holes
- Generates type definitions and encodes BTF from DWARF
Where it doesn't
- Linux is the only supported platform
- Self-hosted installation requires building from source with CMake
- Does not provide decompilation or firmware-analysis workflows

Our verdict on Dwarves

Dwarves is an open-source collection of command-line tools for examining executable and debugging information on Linux. Its core utility, pahole, displays and manipulates data-structure layouts encoded in DWARF, CTF, and BTF. Developers working with compiled programs, Linux kernel code, or eBPF debugging information can inspect type layouts, investigate ABI changes, and understand how structures are represented.

The project is available as a free open-source utility rather than a tiered commercial service. It is distributed as source and built with CMake, then deployed in a self-hosted Linux environment. That model suits teams comfortable managing command-line tooling in their own development or analysis workflows. Support is community-based, so organizations should account for internal expertise when adopting it across solo, small, mid-market, or enterprise environments.

Dwarves stands out for detailed data-layout work. It can inspect type and field offsets and sizes, filter selected classes and structures, reorganize structures to reduce alignment holes and padding, pretty-print input according to a specified type, generate compilable code containing type definitions, and encode BTF information from DWARF. This makes it useful for focused static analysis of debugging metadata, but its scope is deliberately narrow. Teams seeking a broader reverse-engineering suite, including decompilation or firmware analysis, should choose a tool designed for those workflows instead. Pick Dwarves when structure representation and debugging-data conversion are the priority; look elsewhere when you need an end-to-end binary investigation environment.
