Railway vs Coolify for Solo Developers

Quick Comparison

Railway Overview

Railway is a managed PaaS that takes the pain out of deploying full-stack apps. You push your code, and Railway's Nixpacks auto-detect your stack, build everything, and deploy. Need a database? Click a button. Need Redis? Another click. All your services live in one project with environment variables flowing between them automatically.

I've used Railway for multiple side projects and the onboarding experience is genuinely impressive. A Django app with Postgres and Redis was running in production in under 10 minutes. No Dockerfile, no Nginx configs, no SSH. The visual project graph that shows how your services connect is something I wish every platform had.

The pricing is straightforward. You pay $5/month base plus usage for compute and storage. For a typical solo developer project, you're looking at $7-15/month total. Predictable enough to not worry about surprise bills.

Coolify Overview

Coolify is the self-hosted alternative to platforms like Railway, Heroku, and Vercel. You install it on your own VPS, and it gives you a beautiful web dashboard to deploy applications, databases, and services. Think of it as running your own PaaS on a $5-10/month server.

The appeal is obvious. Instead of paying Railway's per-service fees, you pay once for a VPS and deploy as many apps as the server can handle. A single Hetzner or DigitalOcean box running Coolify can host 5-10 small projects comfortably. That's a massive cost advantage if you're running multiple side projects.

Coolify supports Docker, Docker Compose, Nixpacks, and even static sites. It handles SSL certificates through Let's Encrypt, manages databases, and provides one-click deploys from GitHub. The v4 release made the UI significantly better, and the project is actively maintained by a solo developer who genuinely cares about the product.

By the Numbers (2026)

Here are the verified figures behind the comparison, checked on 2026-05-29.

Coolify. The project sits at 56,151 GitHub stars with 4,666 forks and 774 open issues, all under the Apache-2.0 license. The current release is v4.1.1, shipped 2026-05-27, and active work happens on the v4.x branch. The repository has been public since January 2021, so this is not a weekend experiment. Self-hosting is free forever and open source with no feature gating. If you would rather not babysit the Coolify control panel itself, there is also Coolify Cloud starting at $5 per month for two connected servers plus $3 per month for each additional server. You still bring your own deploy targets either way.

Coolify server requirements. The documented minimum is 2 CPU cores, 2 GB of RAM, and 30 GB of free disk. The docs suggest a more comfortable real-world box at 4 cores, 8 GB RAM, and 150 GB disk. It runs on AMD64 and ARM64 across Debian, Ubuntu, the Red Hat family, SUSE, Arch, Alpine, and Raspberry Pi OS 64-bit.

Railway plans. The Hobby plan is $5 per month and includes $5 of usage credit, aimed at solo developers and side projects. The Pro plan is $20 per month per seat with $20 of included usage. There is also a one-time $5 trial credit with no card required.

Railway metered rates. Above the included credit you pay for what your containers consume, billed per second. The published rates are $20 per vCPU per month ($0.000463 per vCPU-minute), $10 per GB of RAM per month ($0.000231 per GB-minute), $0.15 per GB of volume storage per month, and $0.05 per GB of network egress.

A cheap target server. For the Coolify side, a representative entry box is the Hetzner CX23 at EUR 3.99 per month in the Germany and Finland regions, a price in force since 1 April 2026. Hetzner does not publish the full spec sheet on the same page as that adjusted price, so check current specs and pricing before you commit. The point that matters here is the order of magnitude, a few euros per month for a box that can hold several small apps.

Real Cost at Solo-Dev Scale

Numbers in the abstract do not help you decide. Here is a concrete workload priced from the real rates above.

The workload. One always-on web app plus a Postgres database. Assume the app container averages 0.5 vCPU and 0.5 GB RAM around the clock, Postgres averages 0.25 vCPU and 0.5 GB RAM, you attach a 5 GB volume, and you serve 10 GB of egress in the month. These are assumptions, not measurements, so adjust them to your own app.

Railway, one project. Using the published rates: compute is 0.75 vCPU times $20, which is $15.00. Memory is 1.0 GB times $10, which is $10.00. The 5 GB volume is $0.75. Egress of 10 GB is $0.50. That is $26.25 of usage. Your $5 Hobby credit is already absorbed inside that number, so the effective bill is about $26.25 for the month. A lighter app that idles closer to 0.25 vCPU and 256 MB would land far lower, which is why honest Railway math depends entirely on your real resource curve.

Railway, five such projects. Resource usage scales roughly linearly, so five copies of that workload run on the order of $131 per month on a single Hobby account. This is the moment the self-hosted argument gets loud.

Coolify, same five projects. One Hetzner CX23 at EUR 3.99 per month (call it roughly five US dollars at the exchange rate around this date) can comfortably hold five small apps and their databases, since the box clears the documented requirements many times over. Your marginal cost for the sixth and seventh app is zero until you run out of RAM or disk. If you outgrow the box you bump up one tier, you do not get a per-service invoice.

The honest takeaway. For a single modest project Railway lands in the $7 to $30 range depending on how heavy your container actually runs, and you pay zero ops time for that. For five or more projects, Coolify on one small VPS is the dramatically cheaper number, on the order of one server bill instead of a stack of metered ones. The crossover is not a fixed dollar figure, it is the point where your time saved on ops stops being worth the metered premium.

Key Differences

Managed vs. self-hosted. This is the fundamental split. Railway manages everything. Coolify gives you a management layer, but you're still responsible for the underlying server. If your VPS runs out of disk space at 2am, that's your problem with Coolify. With Railway, it's theirs.

Cost structure. Railway charges per service, per minute of compute, and per GB of storage. Coolify is free software, so you only pay for the VPS. If you're hosting one project, Railway is competitive. If you're hosting five or more, Coolify on a $20/month VPS is dramatically cheaper.

Setup time. Railway is ready in minutes. Coolify requires provisioning a VPS, running the install script, configuring DNS, and setting up your first project. It's not difficult, but it's 30-60 minutes versus 5 minutes. For someone who just wants to ship, that gap matters.

Reliability. Railway runs on managed infrastructure with redundancy and automatic failover. With Coolify, your apps are as reliable as your VPS provider and your own configuration. Railway also handles scaling automatically, while Coolify is limited to whatever your single server can handle unless you configure a multi-node setup.

Database management. Both handle databases well, but differently. Railway's one-click databases include automatic backups and connection string injection. Coolify deploys databases as Docker containers with backup scripts you can configure. Railway is more hands-off, Coolify gives you more control.

Ecosystem and integrations. Railway has a marketplace of templates and first-class integrations with common services. Coolify focuses on Docker compatibility, which means anything that runs in a container runs on Coolify. Different philosophies, both effective.

When to Choose Railway

• You want zero server management responsibilities
• Speed of deployment is your top priority
• You're hosting 1-2 projects and budget isn't tight
• You prefer a polished managed experience
• You don't want to think about server updates or security patches

When to Choose Coolify

• You're running multiple projects and want to minimize hosting costs
• You like having full control over your infrastructure
• You already have a VPS and want to maximize its value
• You're comfortable with basic server administration
• You want to avoid vendor lock-in completely

The Verdict

For solo developers who want the fastest path to production with zero ops work, Railway is the better choice. You trade money for time, and for most solo devs, time is the scarcer resource.

But if you're the kind of developer who runs 3-5 side projects and doesn't mind spending an afternoon setting things up, Coolify is a game-changer. The cost savings compound quickly. A $10/month Hetzner box running Coolify can replace $50-80/month worth of Railway services.

My recommendation: if you're deploying your first project and want to focus entirely on building, start with Railway. If you're already comfortable with servers and want to own your infrastructure, Coolify is the smarter long-term play.
