rr is a lightweight record-and-replay framework for Linux that captures the full execution of applications (process and thread trees) and replays it deterministically. It extends gdb with efficient reverse-execution, letting developers debug recorded failures repeatedly with breakpoints and data watchpoints.
Use cases
- debug an intermittent crash by recording it once and replaying deterministically
- reverse-execute under gdb to find where memory was corrupted
- reproduce a race condition reliably using chaos mode
- debug multi-process workloads including containers
- share compact execution traces between machines for collaborative debugging
When to choose
- you debug C/C++ programs on Linux with hard-to-reproduce bugs
- you need deterministic replay and reverse execution with gdb integration
- you want low-overhead recording of single-threaded or multi-threaded workloads
When to avoid
- you need a debugger on Windows or macOS
- your CPU lacks Intel Nehalem+, supported AMD Zen, or AArch64 performance counters
- you run on Xen or a VM without hardware performance counter virtualization
