Coolify vs Railway for Solo Developers

Quick Comparison

Coolify Overview

Coolify is the open-source, self-hosted alternative to platforms like Vercel, Netlify, and Railway. You install it on your own VPS (Hetzner, DigitalOcean, wherever), and it gives you a PaaS experience with a web dashboard, Git-based deployments, one-click databases, and SSL certificates.

The pitch is compelling: get Railway-like convenience without paying Railway prices, running everything on your own infrastructure. Deploy Docker containers, static sites, and databases through a clean web UI. Coolify handles Traefik for reverse proxy, Let's Encrypt for SSL, and Docker Compose for orchestration.

I set up Coolify on a Hetzner VPS and was deploying apps within 30 minutes. The interface is clean and functional. You connect your GitHub repos, configure build settings, and push to deploy. Databases (PostgreSQL, MySQL, Redis, MongoDB) deploy with a click. For a self-hosted solution, the polish is impressive.

Railway Overview

Railway is the managed PaaS that handles everything for you. No servers to provision, no Docker to configure, no SSL to set up. Push code to GitHub, and Railway builds, deploys, and runs your application. Add databases with a click. See logs, metrics, and costs in a unified dashboard.

Railway's strength is elimination of DevOps entirely. Nixpacks auto-detect your project type and build without a Dockerfile. Environment variables wire between services automatically. Scaling happens without you thinking about servers. For a solo developer who wants to focus purely on code, Railway removes every infrastructure concern.

The tradeoff is cost. Railway charges $5/month as a base plus compute and storage usage. A typical full-stack app with a database runs $7-15/month. That's more than running the same app on a $4 Hetzner VPS with Coolify installed.

Key Differences

Cost structure. This is the fundamental difference. Coolify is free software you run on your own server, licensed Apache 2.0 with no feature gates or user limits. An entry-level Hetzner shared-vCPU VPS (2 vCPU, 4 GB RAM) runs in the rough range of EUR 4 to 8 per month after Hetzner's April 1, 2026 price increase, so confirm the current rate on the Hetzner pricing page before you budget. Your total hosting cost for unlimited apps and databases is whatever that one VPS costs. Railway charges $5/month base plus metered compute beyond the included $5 usage credit, which typically totals $10-20/month for a full-stack app. Over a year, the savings with Coolify are significant, with the caveat that you are also buying the ops work back yourself.

Ops responsibility. Railway handles everything: server updates, security patches, backups, scaling, and monitoring. With Coolify, that's all on you. Server goes down at 3am? Your problem. Security vulnerability in the OS? You patch it. Database needs backups? You configure them. The cost savings come with real ops responsibility.

Setup time. Railway is instant. Sign up, connect a repo, deploy. Coolify requires provisioning a VPS, installing Coolify, configuring DNS, and then deploying your apps. The initial setup takes 30-60 minutes. After that, deploying new apps is quick through the Coolify dashboard, but Railway's zero-setup advantage is real.

Reliability. Railway runs on managed infrastructure with teams handling uptime, redundancy, and failover. Coolify runs on whatever server you put it on. A single VPS has no redundancy. If the server goes down, everything goes down. For hobby projects, that's acceptable. For production apps with paying users, Railway's managed reliability matters.

Scaling. Railway scales containers horizontally and vertically through the dashboard. Coolify scales by upgrading your server or adding more servers (multi-server support is available). Railway's scaling is more dynamic and requires no infrastructure knowledge. Coolify's scaling is more manual but gives you full control over resource allocation.

Ecosystem and integrations. Railway offers one-click templates for common stacks, integrated database provisioning, and automatic environment variable linking between services. Coolify offers similar features through its dashboard but the ecosystem is smaller and less polished. Railway feels more refined because it's a funded product with a larger team.

By the Numbers (2026)

The marketing pages blur together fast, so here are the figures that actually decide this, each checked on 2026-05-28.

Coolify

• Latest release: v4.1.1, published 2026-05-27.
• License: Apache 2.0, free forever for self-hosting with no feature gates or user limits.
• GitHub: 56,133 stars and 4,666 forks on the coollabsio/coolify repository, first committed January 2021. Reported user base is around 325,000.
• Primary language: PHP (the dashboard is built on Laravel).
• Catalog: 280+ one-click services per the project's own repository description.
• Coolify Cloud (the optional managed dashboard) is $5/month for 2 connected servers, plus $3/month per additional server, billed monthly or 20 percent cheaper annually. This is the management layer only. You still pay separately for the VPS your apps run on.

Railway

• Hobby plan: $5/month base, which includes $5 of resource usage credit. You always pay the $5 even if usage stays under it.
• Pro plan: $20/month base, including $20 of resource usage credit.
• Trial: a one-time $5 grant for new accounts that expires after 30 days, capped at 1 GB RAM, 2 vCPU, and 2 replicas.
• Metered resource rates (charged beyond your included credit): $20 per vCPU per month, $10 per GB of RAM per month, $0.05 per GB of network egress, and $0.15 per GB of volume storage per month.
• Build system: Nixpacks auto-detects your stack and builds without a Dockerfile, which is the core of the zero-config pitch.

Real Cost at Solo-Dev Scale

Numbers in the abstract do not help, so let me price a realistic solo-dev workload on both. Assume one small full-stack app: a web service sized at 0.5 vCPU and 0.5 GB RAM running 24/7, one PostgreSQL database at 0.25 vCPU and 0.5 GB RAM, a 5 GB volume for the database, and 20 GB of monthly egress. Modest, but representative of a real shipped side project.

Railway, using its published per-unit rates:

• Compute CPU: 0.75 vCPU total across both services at $20 per vCPU per month is $15.00.
• Memory: 1 GB total at $10 per GB per month is $10.00.
• Volume: 5 GB at $0.15 per GB per month is $0.75.
• Egress: 20 GB at $0.05 per GB is $1.00.
• Raw usage subtotal is $26.75. The Hobby plan's $5 base already includes $5 of that usage, so you pay the $5 base plus $21.75 in overage, landing around $26.75 per month total.

That is higher than the post's older $10-20 estimate because these are the current metered rates applied to an always-on service. If you let the app idle or sleep, real usage drops well below this, which is exactly why Railway's own bills vary so much month to month. Treat $27 as the always-on ceiling for this shape of app, not the floor.

Coolify on a single VPS:

• One entry-level Hetzner shared-vCPU box (2 vCPU, 4 GB RAM, 40 GB disk) comfortably runs that same app plus its database, with headroom for two or three more projects.
• At a post-April-2026 rate of roughly EUR 4 to 8 per month for that tier, your all-in hosting cost is that single line item, regardless of how many apps and databases you stack on it.
• Coolify itself adds zero dollars if you self-host the dashboard, or $5/month if you let Coolify Cloud manage it for you.

So at this workload Coolify is somewhere in the range of one fifth to one quarter of Railway's always-on cost, and the gap widens with every additional app you add to the same box. What you are buying with the Railway premium is the absence of patching, backups, and 3am pager duty. That is the entire trade, quantified.

When to Choose Coolify

• You want to minimize hosting costs and have time for basic server management
• You already have a VPS (Hetzner, DigitalOcean) and want a PaaS layer on it
• You value owning your infrastructure and avoiding vendor lock-in
• You're comfortable with SSH, Docker, and basic Linux administration
• You're running hobby projects where some downtime is acceptable

When to Choose Railway

• You want zero DevOps and zero server management
• Getting to production as fast as possible is the priority
• You need reliable, managed infrastructure for production apps
• You don't want to think about security patches, backups, or server maintenance
• The $10-20/month cost is worth the time savings

The Verdict

This is fundamentally a time-vs-money decision. Coolify saves money by giving you PaaS convenience on cheap infrastructure. Railway saves time by eliminating all infrastructure concerns. Both are excellent choices, but they serve different priorities.

If you already manage servers and enjoy that control, Coolify on a Hetzner VPS is the best value in hosting. You get a full PaaS experience for under $5/month with no vendor lock-in.

If you'd rather spend $15/month and never think about servers, Railway is worth every penny. The time you save on ops work goes directly into building your product.

My recommendation: use Coolify for side projects and early-stage prototypes where budget matters most. Use Railway for production apps with paying users where reliability and speed matter more than hosting costs. Many solo developers use both, and that's a perfectly valid strategy.
