Heroku pioneered what a PaaS could be, alongside Cloud Foundry and others, so I’m genuinely sad to see it go down like this.
We built Northflank because we saw enterprises wanting to deploy workloads in their own VPC with Heroku-level simplicity. Over the past 5 years, our mission has been solving the graduation problem where companies outgrow their PaaS and have to eventually migrate.
Northflank runs in your VPC (AWS/GCP/Azure/OCI) with the same git-push experience. We have customers ranging from small startups to governments and public companies who would've otherwise built their own internal developer platform. They either use Northflank as-is in their own cloud or use our API to build their IDP on top of it.
Most common use cases are preview environments and production workloads. Happy to answer questions and throw in some credits if you're evaluating alternatives.
