Coolify
Coolify is a free, open-source self-hosting platform that brings Heroku-style convenience to your own VPS or dedicated server. It supports deploying applications from GitHub, GitLab, or Bitbucket, managing PostgreSQL, MySQL, Redis, and MongoDB databases, and automatically provisioning SSL certificates via Let's Encrypt. A Docker-based architecture means almost any containerised application can be deployed with a few clicks. Coolify replaces the need for separate Nginx configuration, Certbot setup, and manual deployment scripts. It is the tool of choice for developers who want PaaS-level simplicity on infrastructure they fully own and control, without paying per-seat or per-resource to a managed platform.

Fly.io is a cloud platform that deploys Docker containers to edge servers in 35+ regions globally, providing low-latency applications close to users without requiring Kubernetes knowledge. It scales to zero when idle, cutting costs for low-traffic applications, and starts quickly when traffic arrives. Managed Postgres and Redis databases are available as Fly apps on the same private network as your application. The CLI-driven workflow means deployment is as simple as running fly deploy from your project directory. Fly.io is favoured by developers who want globally distributed backend services and APIs without the complexity of managing multi-region cloud infrastructure on AWS or GCP.
