Open Source Python PaaS

PaaSTA is a highly-available, distributed system for building, deploying, and running services using containers and Kubernetes. PaaSTA has been running production services at Yelp since 2016. It was originally designed to run on top of Apache Mesos but has subsequently been updated to use Kubernetes. Over time the features and functionality that PaaSTA provides have increased but the principal design remains the same. PaaSTA aims to take a declarative description of the services that teams need to run and then ensures that those services are deployed safely, efficiently, and in a manner that is easy for the teams to maintain. Rather than managing Kubernetes YAML files, PaaSTA provides a simplified schema to describe your service and in addition to configuring Kubernetes it can also configure other infrastructure tools to provide monitoring, logging, cost management etc.

Websoft9 is a web-based PaaS and Linux panel for self-hosting open-source applications on a user’s own server. It is designed for running many web apps on a single machine instead of requiring a complex Kubernetes-first architecture. The platform provides a graphical interface for installing, managing, and operating more than 200 application templates. It combines application deployment with server administration tools, so users can manage files, containers, users, proxies, SSL, logs, storage, firewalls, and system services from one place. Websoft9 uses familiar technologies such as Docker, Docker Compose, Nginx, Cockpit, Kubernetes, and Swarm rather than introducing a completely new stack. It is useful for individuals, teams, and organizations that want lightweight self-hosting with DevOps-style controls and less manual configuration.

Piku is a minimalistic Platform as a Service (PaaS) that enables users to deploy applications to their own servers using simple Git push commands.

ZaneOps is a self-hosted, open-source PaaS for deploying and managing applications, services, databases, workers, and static sites. It is designed as an alternative to platforms like Heroku, Railway, Render, Vercel, and Netlify while keeping ownership of infrastructure in the user’s hands. The platform uses Docker Swarm for scalable container orchestration and Caddy for flexible routing and web serving. It gives developers a polished dashboard for managing projects, deployments, logs, URLs, environment variables, resource limits, and service configuration. ZaneOps supports Docker image deployments and deployment webhooks, making it useful for automated release workflows. It is aimed at startups, self-hosters, and teams that want modern deployment convenience without giving up control over servers, costs, or data.
