Coolify vs Dokku
Both are alternatives to Heroku. Here's how they stack up — verified facts, no spin.
Also searched as Dokku vs Coolify — same comparison, one verdict.
Coolify
TOP PICKSelf-hosted Heroku — one server, Apache-2.0, everything included.
Coolify installs on a plain VPS and gives you Git-push deployment, automatic TLS, databases, backups, preview environments and a dashboard that non-specialists can use. Apache-2.0 with around 60k stars, and its growth over the past two years has been the clearest signal in this category. On a $12 server it will comfortably run several applications with their databases — the same work Heroku would bill well over $100 for. You are trading a monthly invoice for a server you now own, and for many teams that is the correct trade rather than a compromise.
Dokku
The original self-hosted PaaS — small, stable, unglamorous.
Dokku has been doing this since 2013 and describes itself accurately as the smallest PaaS implementation you have seen: Git-push deployment via Docker, Heroku buildpack support so existing apps often deploy unchanged, and a plugin system for databases and TLS. MIT, around 32k stars. It has no web interface — everything is the command line — and that is deliberate. For someone comfortable in a terminal it is the most dependable option here, and it has outlived several better-funded competitors.
