## What it is
Recon is an Erlang library providing safe functions and scripts for diagnosing and debugging Erlang systems in production. It allows inspecting running nodes without risking crashes or unsafe operations.

## Use cases
- debug erlang node in production
- trace erlang processes safely
- profile memory usage of erlang VM
- inspect running erlang system
- diagnose production erlang issues
- find process leaks in erlang

## When to choose
- you run Erlang/OTP systems in production and need safe diagnostics
- you want to trace or profile without stopping the node
- you need to inspect process, port, or memory state on a live system

## When to avoid
- you need general-purpose application monitoring with dashboards and alerting
- your stack is not Erlang/Elixir/BEAM-based
- you want automated continuous profiling rather than on-demand debugging

## Facets
- artifact type: library
- maturity: stable
- function: tracing, monitoring, benchmarking, developer-tools
- domain: developer-tools, monitoring
- platform: windows, cross-platform
- tags: erlang, otp, production-diagnostics, rebar3, instrumentation, debugging, linux, macos
