A Railway Alternative for AI Agents and Full-Stack Apps
Compare NEXUS AI and Railway on pricing, AI agent hosting, MCP tools, backups, and multi-cloud deploys, plus a step-by-step migration from Railway.
Hosting AI agents on each platform
Both platforms run long-lived agent processes. Railway offers a hosted MCP server that exposes a railway-agent tool, plus Cloud Agents VMs for long-running agents. On NEXUS AI an agent deploys as a container with Postgres, Redis, a persistent volume, and background workers in the same deployment. API keys live in the AES-256-GCM secrets vault, model calls can go through the NEXUS AI Gateway for provider failover and budgets and rate limits per team or user path, and an OpenClaw gateway deploys in one step. Short-lived agent environments can auto-destroy on a schedule.
Letting agents operate the platform
NEXUS AI exposes 74 MCP tools for deployments, databases, backups, storage, secrets, domains, and support, each gated by one of 25 OAuth scopes. Destructive actions need their own scopes: deleting a deployment, database, volume, or bucket needs a delete scope, and restoring a deployment database or applying schema changes needs db:admin. That means an agent can deploy and read logs without being able to drop data. Database queries and schema fixes that an agent runs are recorded in the audit log.
Pricing: usage-based vs fixed plans
Railway charges a plan fee (Free, $5 Hobby, $20 Pro) that includes the same amount of usage, then bills compute by the second: about $20 per vCPU-month, $10 per GB-month of memory, $0.15 per GB-month of volume storage, and $0.05 per GB of egress. A service that keeps a full vCPU and 1 GB of memory busy all month uses about $30 of resources before storage and traffic. NEXUS AI Starter is $29 and Pro is $149, with managed hosting subject to plan limits. Apps deployed into your own cloud account and requests using your own AI key are billed separately by those providers. Compare resource sizing and measured use before choosing a plan.
Backups you can restore somewhere else
Railway backs up volumes on demand or on a daily, weekly, or monthly schedule, kept for 6, 27, or 89 days, and restores into the same project and environment. NEXUS AI backs up Postgres, MySQL, MongoDB, and Redis on demand or on a schedule with configurable retention, lets you download any backup through a signed URL, and restores either in place or into a different Postgres service, for example to seed staging from production. Standalone databases snapshot and restore into a new database, so the original stays untouched.
When Railway is the better fit
Railway fits teams that prefer usage-based billing, its service templates, and its agent integrations. Pro supports large service allocations, with published maximums that include replica multiplication; check the resource table before sizing a single instance. Both platforms provide agent tools and backup workflows. Choose based on measured resource use, recovery requirements, and whether the app must run in a cloud account you control.
How it works
- Export your Railway variables and dump the database.
- Deploy the same repo on NEXUS AI with Postgres, Redis, and your variables.
- Upload the dump and restore it into the new database.
- Verify the app, move your domain, and let agents operate it through MCP.

Move an app from Railway to NEXUS AI
| Step | Command |
|---|---|
| Export the service variables from Railway | railway variable list -s <service> --kv > app.env |
| Enable Public Access on the Railway Postgres service, then dump it | pg_dump "$DATABASE_PUBLIC_URL" -Fc -f railway.dump |
| Deploy the same repo with Postgres and Redis (remove Railway database URLs from app.env first; NEXUS AI injects its own) | nexus deploy source --repo https://github.com/you/app --name my-app --provider docker --services postgres,redis --env-file app.env --environment PRODUCTION --wait |
| Find the new database service ID | nexus db services my-app |
| Upload the Railway dump | nexus db backup-upload <service-id> ./railway.dump |
| Restore it into the new database | nexus db restore <service-id> <backup-id> --yes |
| Check the app, then point your domain at it | nexus deploy logs my-app --follow |
NEXUS AI vs Railway

Frequently asked questions
What is the best Railway alternative for hosting AI agents?
It depends on what the agent needs around it. NEXUS AI suits agents that need a database, Redis, workers, and storage in one deployment, keys in an encrypted vault, model calls routed through a gateway with budgets, and MCP access scoped per tool. Railway suits agents that fit in a single service or a Cloud Agents VM and benefit from usage-based billing.
Is NEXUS AI cheaper than Railway?
Not always. Compare your measured compute, memory, storage, and traffic use with both plans. NEXUS AI Starter is $29 and Pro is $149 with managed runtime limits; resources in your own cloud account and your own AI-key usage are additional provider charges. Railway includes usage credit in its plan fee, then charges for resources beyond that credit.
Is there a free Railway alternative?
NEXUS AI has a free plan with one deployment, meant for testing and development rather than production business apps. Railway's free plan includes $1 of usage per month after a one-time $5 trial credit.
Is there an open-source Railway alternative?
NEXUS AI is not open source, but NEXUS AI Enterprise runs inside your own cloud account or on-premises. If open source is a hard requirement, self-hosted platforms such as Coolify and Dokploy are the usual choices.
How do I migrate from Railway to NEXUS AI?
Export your service variables with railway variable list --kv, dump the Railway Postgres database with pg_dump over its public URL, deploy the same repo with nexus deploy source and --env-file, then upload the dump with nexus db backup-upload and restore it with nexus db restore. The full commands are in the migration table on this page.
Can AI agents deploy to NEXUS AI the way they deploy to Railway?
Yes. Connect Claude, Cursor, Codex, or another MCP client to https://mcp.nexusai.run/mcp. Agents can deploy, read logs, scale, back up, restore, and roll back, limited to the OAuth scopes you grant. Database queries and schema fixes an agent runs are recorded in the audit log.
Does NEXUS AI support databases and workers like Railway?
Yes. A deployment can include PostgreSQL, MySQL, MongoDB, Redis, and background workers on the same service network, plus persistent volumes and S3-compatible buckets.
