The complete health check for your Rails application
11 automated scanners analyze your security, test coverage, CI/CD pipeline, deployment readiness, and more. One score. Shareable reports your CTO will actually read.
Health Score
Technical debt is invisible — until it isn't
Most Rails teams don't realize their app is unhealthy until something breaks in production.
Security vulnerabilities pile up
Known CVEs sit in your gems and npm packages for months. You won't notice until something breaks.
Tests go missing and nobody notices
Test coverage silently erodes. New features ship without tests. System tests disappear from CI.
Database indexes are missing
Foreign key columns without indexes. Queries that worked fine at 1,000 rows crawl at 100,000.
Production errors go unnoticed
No error tracking, no monitoring, no health checks. Users find your bugs before you do.
How it works
Three steps to a healthier Rails app
Connect your GitHub repo
Sign in with GitHub and select the repositories you want to monitor. Read-only access — we never touch your code.
11 scanners analyze your app
We scan your Gemfile, schema, routes, CI config, and more. Security vulnerabilities, test coverage, deployment readiness — checked automatically in seconds.
Get a health score and shareable report
A single 0-100 score with a detailed breakdown across 4 categories. Share a clean report link with stakeholders — no jargon.
Security
Find vulnerabilities in your Ruby gems and JavaScript packages
Three scanners work together to catch security issues across your entire stack — from Gemfile.lock to npm packages to production configuration.
Gem Security Scanning
Checks every gem in your Gemfile.lock against the Ruby Advisory Database for known vulnerabilities, CVEs, and security advisories.
JavaScript Security
Scans yarn.lock, package-lock.json, or import maps for npm package vulnerabilities. Also checks your Node.js version against the LTS schedule.
Security Configuration
Checks force SSL, Content Security Policy, rate limiting, parameter filtering, hardcoded secrets, and more. 14 security checks across your production config.
Application Quality
Track your Rails version status and test coverage health
Know exactly where you stand on framework support and how well your test suite covers your application code.
Rails Version Monitoring
Tracks your Rails and Ruby versions against support status and end-of-life dates. Flags when you're on an unsupported release series so you can plan upgrades before security patches stop.
Test Coverage Health
Analyzes your test suite structure — test-to-code ratio, system test presence, framework detection (Minitest or RSpec), and test tooling like SimpleCov, FactoryBot, and WebMock.
Infrastructure
Verify your CI/CD pipeline, deployment setup, and monitoring
Is your CI actually running tests? Is your deployment automated? Would you know if production went down? RailsHealth checks all of it.
CI/CD Pipeline Analysis
Detects your CI provider (GitHub Actions, CircleCI, GitLab, etc.) and verifies that tests, security scanning, and linting actually run in your pipeline.
Deployment Readiness
Checks for Dockerfile, deployment config (Kamal, Fly.io, Heroku), Puma workers, health endpoints, encrypted credentials, and background job processors.
Monitoring & Observability
Verifies you have error tracking (Sentry, Honeybadger), APM (Skylight, New Relic), structured logging, and background job monitoring in place.
Code Health
Keep your dependencies fresh, your database optimized, and your tools configured
The small things that compound into big problems. Missing database indexes, outdated gems, and absent linting tools all erode your codebase over time.
Dependency Freshness
Shows how current every gem is and flags those falling dangerously behind. Distinguishes minor updates from major version jumps that need planning.
Database & Schema Health
Parses your schema.rb to find missing indexes on foreign keys, unindexed query columns, tables without timestamps, and overly wide tables. Checks for strong_migrations gem.
Code Quality Tooling
Checks for RuboCop or StandardRB, Brakeman, bundler-audit, ERB linting, type checking, and code complexity analysis. Recommendations for every missing tool.
Built for teams that ship Rails apps
Shareable Reports
Generate clean, jargon-free reports for CTOs, clients, and project managers. Share via a simple link — no login required.
Automated Weekly Scans
Your repositories are scanned automatically every week. Always have an up-to-date picture without lifting a finger.
Score Drop Alerts
Get notified immediately when your health score drops so you can act before problems escalate.
