Railway runs your workloads on their infrastructure. Convox deploys directly into your own AWS account via Bring Your Own Cloud (BYOC), so your data never leaves your environment. When a customer asks where their data lives, your answer is 'our AWS account' — not 'a third-party PaaS vendor's cloud.' That matters the moment you close your first enterprise deal.
You get the same `convox deploy` simplicity that makes Railway feel effortless — but the underlying infrastructure is yours. A single convox.yml defines your services, environment, and scaling rules in plain text that lives in your repo. If you ever outgrow Convox, you own the AWS resources underneath and you're not starting from zero.
Railway is built for individual developers. Convox is built for engineering teams of 5–20 that don't have a dedicated DevOps hire yet. Role-based access, multi-environment promotion, deployment pipelines, and audit logs are standard — not add-ons. Your solo ops person gets leverage, not another tool to babysit.
Railway can't tell your enterprise prospect that their data is isolated in your own VPC on your own AWS account. Convox can. Because BYOC means Convox provisions infrastructure inside your AWS environment — private subnets, your security groups, your IAM boundaries. Compliance isn't a blocker; it's a checkbox you already pass.
Convox runs on EKS under the hood — managed, scalable, and AWS-native — without forcing you to learn Kubernetes to operate it. Railway abstracts infra away entirely, which feels great until you need a feature it doesn't support. Convox gives you the escape hatches when you need them and stays out of your way when you don't.
Railway's per-usage pricing can surprise you at scale. Convox pricing is flat and predictable — you pay for the platform, and your AWS bill is your own to optimize. When your CTO is deciding between a DevOps hire and a platform investment, the math on Convox is straightforward.
