Nexos vs Railway: a preview-first alternative for branch environments

Railway has become the go-to platform for indie devs and small teams who want Heroku-style simplicity with modern pricing and a cleaner UI. It is particularly good for running a production service that needs a Postgres attached to it.

What Railway is less focused on is the branch-preview workflow. You can wire it up with environments and a bit of glue, but you are assembling it yourself rather than having it on by default.

Railway's strengths

• Great UX for one-off projects and production services
• Attached Postgres, Redis, MongoDB with one click
• Good CLI for local development
• Transparent usage-based pricing

Where Railway leaves you wiring it yourself

If you want a preview environment per pull request on Railway, you are configuring GitHub Actions, managing environment variables yourself, and paying for each attached database as its own service. At scale across a team with many open branches, that adds up fast and there is no built-in notion of an ephemeral, short-lived environment that gets torn down when the PR closes.

Nexos is preview-first

In Nexos, the preview workflow is not a configuration you build — it is the entire product. Every git branch that gets pushed automatically gets:

• Its own running container from your Dockerfile
• Its own Postgres and Redis (if configured)
• A preview URL that updates automatically on every push
• Auto-teardown when the branch is deleted

The cost of ten preview environments on Nexos is typically a fraction of the same on Railway, because databases are lightweight preview-sized containers per environment rather than full managed services, and paused environments do not bill.

When each is right

Railway is a great choice for running your production services.

Nexos is the right choice for preview environments. Many teams use both — Railway hosting production, Nexos handling the full-stack preview layer for every pull request.
