panicparse is a Go tool and library that parses Go panic stack traces, densifies and deduplicates goroutines with similar stacks, and renders more compact, readable crash output. It ships as the `pp` CLI for piping crash dumps, plus a Go package with HTTP handler middleware and a web snapshot server.

Use cases

• make Go panic stack traces readable and compact
• deduplicate hundreds of similar goroutine stacks after a server crash
• debug deadlocks in heavily parallelized Go processes
• parse race detector output from go test -race
• pipe go test output through pp to catch panics automatically
• serve a readable live snapshot of goroutines instead of net/http/pprof
• export crash dumps as HTML for sharing

When to choose

• you debug Go crashes or deadlocks with many goroutines
• you want a CLI you can pipe stderr through to prettify panics
• you want a library to embed panic parsing or an HTTP middleware in a Go service
• you need cross-platform support (Windows, macOS, Linux) with Go modules

When to avoid

• your project is not written in Go
• you need a general-purpose debugger or profiler rather than panic trace formatting
• you need to parse stack traces from languages other than Go
• you want a GUI-based crash analysis tool
