How Coolify’s self-hosted PaaS changes VPS deployment economics

The Heroku stagnation

Heroku removed its free tier in November 2022. This change removed the main reason many developers chose the platform. Since then, costs for staying on Heroku have increased. A typical production application with a web dyno, a worker dyno, a PostgreSQL database, and a Redis cache costs between $115 and $165 per month. On February 6, 2026, Heroku announced a transition to a "sustaining engineering" model. This model focuses on stability, security, and reliability. It stops the development of new features. It also stops the sale of new enterprise contracts. Heroku is no longer building new features. For existing customers, the platform remains available, but the innovation gap between Heroku and its actively developing alternatives will widen.

The cost compounds as teams add services. Heroku bills Heroku Postgres and Redis as separate add-ons. On the Eco tier, $5 per month covers 1,000 shared dyno hours. For teams running three or four services, costs scale quickly.

The shift to self-hosted infrastructure

The industry now splits into three ownership models: hosted PaaS, bring-your-own-cloud (BYOC), and self-hosted. Hosted platforms like Render and Railway run workloads on infrastructure they own. BYOC platforms like Qovery deploy into accounts that the user owns, such as AWS or GCP. Self-hosted tools like Coolify and Dokploy run on servers that the user provisions.

Coolify provides a way to run applications on a VPS using a web dashboard. It manages container orchestration, SSL certificate provisioning, and database management. You can deploy code from GitHub, GitLab, Bitbucket, or Gitea. The platform includes 280 plus one-click templates for services like PostgreSQL, MySQL, and Redis. It supports Nixpacks and Dockerfile builds. The cost difference is massive.

Teams that migrate from expensive managed platforms to a self-hosted setup on a $24 per month DigitalOcean droplet often see their monthly infrastructure spend drop from over $150 to a much smaller amount.

Coolify has 59,300 GitHub stars and 325,000 reported users. Other options exist for different needs. Dokploy has 37,000 stars but remains at version 0.30.2. It uses Docker Swarm and includes an AI-powered Docker Compose generator. CapRover has a long history since 2017 and includes 100 plus applications. It uses Docker Swarm to provide clustering across multiple servers. Dokku is a CLI-based option for small teams. If you already manage Linux servers, the math for Coolify makes sense.

The cost of independence

Control requires work.

You manage the server.

Self-hosting effectively eliminates vendor lock-in. You choose the data center and the hardware. However, you also take on the operational burden. You must handle OS updates, security patches, backups, and monitoring. Teams must add roughly $150 to $300 per month in costs for a production-ready observability stack like Sentry, Plausible, or Better Uptime. For a small team, the server bill is small. For a large team, the engineering time is the real cost. A DevOps engineer in the US makes a median total compensation of $150,000. Eight hours of maintenance per month costs $576.

The decision to leave a managed platform often comes down to a comparison of engineering hours and monthly invoices. For a single application, a full PaaS is often more effort than benefit. As a project grows, the efficiency of a self-hosted solution increases.

Coolify v4 became stable in April 2026. The v5 rewrite focuses on multi-server scalability. Will the v5 migration path be smooth? The platform continues to grow.
