## What it is
Eye is a Ruby-based process monitoring and supervision tool inspired by Bluepill and God. It watches processes via pid files, restarts them on failure, and supports checks on CPU/memory, flapping triggers, and chained starts.

## Use cases
- keep my app processes alive and restart them when they crash
- monitor cpu and memory usage of background daemons
- daemonize processes with pid file management
- replace god or bluepill for process supervision
- restart a group of processes one by one with delays
- run processes as a specific user and group

## When to choose
- you want a lightweight, config-driven process supervisor on a single server
- you are already comfortable with Ruby and want Bluepill/God features with fewer bugs
- you need chained restarts, flapping detection, and resource checks

## When to avoid
- you need multi-node or container orchestration - use systemd, supervisord, or Kubernetes instead
- your stack is not Ruby and you prefer a language-independent supervisor
- you need modern actively developed tooling - releases are infrequent

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: monitoring, cli, scheduling
- domain: monitoring, self-hosted
- platform: cli, ruby
- tags: process-monitor, process-supervisor, daemonize, ruby-gem, bluepill-alternative, god-alternative, devops, command-line, linux, macos
