Rails Health Checks

Rails health check endpoints gem

A Rails engine that adds production-grade health check endpoints to any Rails app. Goes well beyond the built-in /up endpoint with 11 built-in checks, parallel execution, structured JSON responses, Prometheus metrics, and a clean configuration DSL.

What you get

• Parallel check execution via Concurrent::Future — response time bounded by the slowest check, not the sum
• Result caching (config.cache_duration) to absorb high-frequency probe traffic
• Prometheus text exposition at GET /health/metrics (always HTTP 200)
• Check groups (config.group) expose subsets at /health/:group
• Per-environment toggling, boot-time validation, and bearer token / IP / custom auth
• rails generate rails_health_checks:initializer scaffolds a fully-commented config file
• Drop-in replacement for OkComputer — see MIGRATING_FROM_OKCOMPUTER.md

Mounting it

# Gemfile
gem "rails_health_checks"

# config/routes.rb
mount RailsHealthChecks::Engine, at: "/rails-health-checks"
