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.
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.
Render is a platform — it bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
Including when one of these alternatives ships a major update. Free.
