Self-hostable PaaS alternative to Vercel/Heroku
Coolify is a self-hosted PaaS that handles deployment, SSL, database provisioning, and reverse proxying for your applications. Point it at a server, connect your Git repos, and it handles builds, deployments, SSL certificates, and reverse proxying.
Docker-powered PaaS for app lifecycle management
It's a single-server PaaS (platform-as-a-service) that turns any Linux box into a deployment platform. Git push, automatic Docker build, zero-downtime deploys, SSL via Let's Encrypt, and plugin support for databases.
Scalable PaaS with automated Docker+nginx
Capacitor bridges web apps to native mobile platforms: write your app with web tech, then access native device APIs (camera, GPS, push notifications) through a clean plugin system. It's a platform-as-a-service (PaaS) you install on your own server.
ZaneOps is a self-hosted PaaS (platform-as-a-service) that aims to be the open source Heroku/Railway. Push your code or Docker image, ZaneOps handles deployment, HTTPS, environment variables, and scaling on your own server.
Swiftwave handles it. Point it at a VPS, push your code, and it builds, deploys, and manages SSL certificates automatically.
