Convox replaces Heroku's git-push workflow with `convox deploy` — a single command that builds, pushes, and releases your app on infrastructure you own inside your own AWS account. No Heroku-flavored abstraction layer sitting between you and your cloud bill. You keep the PaaS experience and the infrastructure control.
A `convox.yml` file replaces your Heroku Procfile and add-on config, and it reads like plain English. If your app already runs in a Dockerfile — or you're willing to write one — Convox handles the rest: load balancers, SSL, environment variables, scaling, and scheduled tasks are all declared in one file. Most teams ship their first Convox deploy within a day.
Unlike Render or Railway, Convox is Bring Your Own Cloud. Every resource — Kubernetes pods, RDS instances, S3 buckets, VPC — runs inside your own AWS account, under your own IAM policies. That matters for SOC 2, HIPAA, and any customer contract with a data residency clause. You get PaaS simplicity without giving a third party keys to your production environment.
Heroku's post-Salesforce pricing adds a significant markup on top of the AWS resources your app already runs on. Convox charges a flat platform fee — you pay AWS directly for compute, and the savings compound as you scale. Teams running 4–10 dynos routinely see 50–70% reductions in their total infrastructure spend after migrating to Convox.
Convox was built for engineering teams with zero to one ops staff. A single `convox rack install` provisions a production-grade AWS environment — EKS cluster, ALB, RDS, networking — in under 30 minutes. After that, your developers deploy with the same command every time. No Terraform expertise, no Kubernetes YAML, no on-call rotation for infrastructure incidents Heroku used to absorb.
Render and Railway are great for teams who want someone else to own the infrastructure forever. Convox is for teams who've outgrown that tradeoff — who want the deployment simplicity of Heroku but the data ownership, compliance posture, and cost structure that only running in your own AWS account provides. Sub-1% monthly churn means teams that land on Convox tend to stay.
