HivePaaS

HivePaaS is an open-source, resource-efficient PaaS solution for deploying and managing applications on your own servers. It supports deploying from Docker images or Git repositories with built-in Dockerfile generation for many languages and frameworks, functions in multiple runtimes, automatic TLS, autoscaling, monitoring, backups, role-based access, and a REST API. It runs on single or multi-node Docker Swarm clusters, providing a self-hosted alternative to Heroku, Render, and Coolify.
