Used For

• +**You're manually deploying to three different servers and one always breaks** → Push to GitHub once, Railway handles the rest automatically
• +**Your app dies when traffic jumps from 100 to 1,000 users** → Auto-scaling kicks in without you touching anything
• +**Setting up databases takes 4 hours and you screw up the config** → Click a button, get PostgreSQL running in 30 seconds
• +Pull request environments - every code change gets its own live preview URL for testing
• +Built-in monitoring shows exactly when things break instead of finding out from angry users

Best For

• >Your Heroku bill doubled and you're tired of getting screwed
• >You want to ship side projects without becoming a DevOps expert
• >Your startup hit traffic spikes and everything crashed at 2am

Not For

• -Big enterprises needing custom VPC setups — this is cloud-only with limited control
• -Static website builders — you're paying for server power you don't need
• -Penny-pinchers running one tiny app — the bandwidth costs add up fast at scale

Pairs With

• *GitHub (where your code lives and triggers automatic deployments)
• *PostgreSQL (Railway's one-click database that actually works unlike Heroku's expensive add-ons)
• *Vercel (for your marketing site while Railway handles the heavy backend API work)
• *Slack (where Railway sends alerts when your app crashes or scales up)
• *Stripe (for payments since Railway handles the API backend that processes transactions)

The Catch

• !The free tier's 500 execution hours disappear faster than you think — hobby projects hit the limit in days
• !Bandwidth overages will surprise you with $50+ bills if your app serves a lot of API calls
• !No built-in scheduled jobs, so you'll hack together workarounds or pay for external cron services

Bottom Line

Deploy apps in seconds instead of spending weekends fighting with AWS configs.
