Overview
Porter is an open-source application platform that provides a Heroku-style developer experience on top of existing Kubernetes clusters. It offers a dashboard for deploying web services, workers, and cron jobs; manages Helm chart releases under the hood; and integrates with GitHub Actions for CI/CD. Teams can run Porter on their own AWS, GCP, or on-premise Kubernetes without vendor lock-in.
Where it falls short of Heroku
- Requires an existing Kubernetes cluster — not suitable for bare-metal without k8s experience
- Self-hosted version lacks some features available on the managed cloud
- Active development has shifted focus toward the managed offering
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
