Heroku vs Railway — The Old Guard vs the Modern Contender
Heroku's simplicity is legendary, but Railway's speed and pricing make it the clear winner for modern apps. Pick Railway unless you're stuck in 2012.
Railway
Railway deploys in seconds with zero-config magic, while Heroku's dynos feel sluggish and overpriced. At $5/month for a full app vs Heroku's $7 for a basic dyno, Railway is cheaper and faster.
This Isn't a Fair Fight Anymore
Heroku defined Platform-as-a-Service (PaaS) with its git push heroku master simplicity, but it's become the legacy option—slow, expensive, and stuck in its ways. Railway launched in 2021 as a direct response, offering instant deploys from GitHub and transparent pricing that doesn't nickel-and-dime you for add-ons. They're both PaaS tools, but Railway is built for 2024's developer expectations: speed, cost, and zero configuration.
Where Railway Wins
Railway's deploy previews are free and automatic on every PR, while Heroku charges $7/month per app for Review Apps. Railway's $5/month Starter plan includes 1 GB RAM, 2 vCPUs, and 1 GB disk—compare that to Heroku's $7/month Hobby dyno with 512 MB RAM and no guaranteed CPU. Railway also has built-in Redis and PostgreSQL that scale seamlessly, whereas Heroku makes you provision expensive add-ons ($15/month for Redis, $9/month for PostgreSQL Mini). If you value your time and money, Railway is the obvious pick.
Where Heroku Holds Its Own
Heroku's ecosystem of add-ons (like SendGrid, New Relic, or Papertrail) is vast and well-integrated—over 200 options vs Railway's handful. Its CLI and dashboard are polished and familiar, with a decade of documentation. For enterprise teams, Heroku's SSO, audit logs, and compliance certifications (SOC 2, HIPAA) are more mature. If you're running a complex, add-on-heavy app with strict compliance needs, Heroku still has an edge.
The Gotcha: Switching Costs and Lock-in
Migrating from Heroku to Railway isn't trivial—you'll need to rewrite your Procfile to use Railway's Nixpacks or Dockerfiles, and reconfigure add-ons as Railway services. Heroku's buildpacks are a blessing and a curse: they work magically but lock you into Heroku's stack. Railway uses standard Docker, which is more portable but requires more upfront config. Also, Railway's free tier is generous (500 hours/month), but it's newer—if you hit a bug, support might be slower than Heroku's established channels.
If You're Starting a New App Today
Use Railway. Spin up a Next.js or Node.js app, connect your GitHub repo, and watch it deploy in under 30 seconds—no config, no credit card. At $5/month, you get a production-ready setup with a database included. Heroku would cost you at least $16/month ($7 for dyno + $9 for PostgreSQL) and take minutes to deploy. For side projects or startups, Railway's pricing and speed are unbeatable. Only consider Heroku if you're already deep in its ecosystem or need a specific add-on Railway lacks.
What Most Comparisons Get Wrong
People obsess over Heroku's simplicity, but that's outdated—Railway is just as simple with its one-click deploys. The real difference is pricing transparency: Railway shows costs per service upfront, while Heroku hides fees in add-ons and dyno types. Also, Railway's resource usage is metered (you pay for what you use beyond the free tier), vs Heroku's rigid dyno pricing. Don't fall for the 'Heroku is easier' myth—Railway is easier and cheaper.
Quick Comparison
| Factor | heroku | railway |
|---|---|---|
| Base Pricing | $7/month for Hobby dyno (512 MB RAM, no guaranteed CPU) | $5/month for Starter plan (1 GB RAM, 2 vCPUs, 1 GB disk) |
| Deploy Previews | $7/month per app for Review Apps | Free and automatic on every PR |
| Database Included | $9/month for PostgreSQL Mini add-on | Built-in PostgreSQL and Redis, scales with app |
| Deploy Speed | 2-5 minutes per deploy with buildpacks | Under 30 seconds with Nixpacks/Docker |
| Add-on Ecosystem | 200+ integrated add-ons (e.g., SendGrid, New Relic) | Limited to core services (PostgreSQL, Redis, etc.) |
| Free Tier | 550 dyno hours/month, sleeps after 30 mins inactivity | 500 hours/month, no sleep, includes database |
| Compliance | SOC 2, HIPAA, enterprise SSO, audit logs | Basic security, no advanced compliance certs yet |
| Configuration | Procfile and buildpacks, Heroku-specific | Docker or Nixpacks, standard and portable |
The Verdict
Use heroku if: You need enterprise-grade compliance (SOC 2/HIPAA) or rely on specific Heroku add-ons like SendGrid.
Use railway if: You're building a modern app and want fast, cheap deploys with a database included—side projects or startups.
Consider: Vercel for frontend-heavy apps—it's even faster for Next.js but lacks Railway's backend flexibility.
Railway deploys in seconds with zero-config magic, while Heroku's dynos feel sluggish and overpriced. At $5/month for a full app vs Heroku's $7 for a basic dyno, Railway is cheaper and faster.
