About ExitCode
Turns a cryptic exit status into a plain answer: what killed the process, why, and what to do next.
The Unix convention is that a process killed by signal N exits with 128 + N, so
137 is SIGKILL (often the out-of-memory killer), 143 is a graceful SIGTERM, and
139 is a segfault. ExitCode decodes that across three contexts — process/shell, Docker &
Kubernetes, and curl — entirely in your browser. It is a reference, not a diagnosis: confirm against the
program’s own logs.
