Is Dokku or PostgreSQL better?

Neither clearly leads. Dokku starts at Free and PostgreSQL at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Dokku or PostgreSQL?

Dokku starts at Free and PostgreSQL at Free.

Does Dokku or PostgreSQL run on more platforms?

Dokku runs on Linux, Docker, CLI, Self-hosted. PostgreSQL runs on Linux, Windows, macOS, BSD, Unix.

Can I use Dokku for free?

Both have a free tier, so you can try either at no cost before committing.

What is Dokku best used for?

Dokku is most often used for running a dozen side projects and client applications on one virtual private server with heroku style deployment, moving off a managed platform when the monthly bill has grown faster than the traffic has, a consultancy that wants buildpack deployments without teaching every client team kubernetes, keeping a legacy procfile application alive on hardware you control after a managed platform deprecates its stack. Of those, running a dozen side projects and client applications on one virtual private server with heroku style deployment and moving off a managed platform when the monthly bill has grown faster than the traffic has are not what PostgreSQL is typically brought in for.

What can Dokku do that PostgreSQL cannot?

Dokku covers Git push deploy, Heroku buildpacks, Datastore plugins, Automatic certificates. PostgreSQL covers ACID Compliance, JSON/JSONB Support, Full-text Search, Extensibility.

The short version

Each has a real cost: Dokku one maintainer accounts for nearly all human commit activity and the project records roughly 10,500 US dollars of annual income on Open Collective, which is not enough to fund a maintainer, so continuity rests on one person continuing to volunteer.; PostgreSQL requires manual scaling across multiple machines for very large deployments
They diverge on capability: Dokku covers Git push deploy, PostgreSQL covers ACID Compliance.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Dokku

One maintainer accounts for nearly all human commit activity and the project records roughly 10,500 US dollars of annual income on Open Collective, which is not enough to fund a maintainer, so continuity rests on one person continuing to volunteer.
Dokku Pro asks 849 US dollars for a lifetime licence from a project with no disclosed legal entity behind the promise and no published refund terms, while the product is still described as in development at early bird pricing.
Dokku is single-server by design, and the k3s scheduler that provides multi-node support is missing log retrieval, process inspection and content-based health checks, with a post-run hook the documentation says does not consistently fire.
Supported operating systems are limited to Ubuntu 22.04 or 24.04 and Debian 11 or later, so organisations standardised on Red Hat, Rocky or Alma Linux cannot run it on their approved base image.
Backups are separate commands per datastore plugin that you schedule yourself, with no unified snapshot, no point-in-time recovery and no tested restore path, so verifying that a restore works is entirely your responsibility.

PostgreSQL

Requires manual scaling across multiple machines for very large deployments
Performance tuning requires deep knowledge of database internals
No built-in graphical admin interface; command-line tools are primary method

Answered from the vendors’ own pages

Dokku: Is Dokku still maintained?

Yes. Version 0.38.27 shipped in August 2026 with roughly six releases in the preceding two months. The caveat is that one maintainer writes nearly all of it.

PostgreSQL: Is PostgreSQL completely free?

Yes. PostgreSQL is completely free and open source with no licensing fees or restrictions on use.

Source

Dokku: What does Dokku Pro give me over the free edition?

A web dashboard, a JSON REST API, git push over HTTPS, browser log tailing, team management and email support from the maintainers. It costs 849 US dollars once for one production and two pre-production servers.

PostgreSQL: What platforms does PostgreSQL run on?

PostgreSQL runs on all major operating systems including Linux, Windows, macOS, BSD, and commercial Unix variants, and has been proven highly scalable managing terabytes to petabytes of data.

Source

Dokku: Can Dokku run across multiple servers?

Only through the k3s or Nomad schedulers. The k3s path is missing several commands and health check types, and the older Kubernetes scheduler is deprecated and no longer developed.

PostgreSQL: What procedural languages are supported?

PostgreSQL supports stored functions and procedures in multiple languages including PL/pgSQL, Perl, Python, Tcl, Java, JavaScript, R, and Rust.

Source

Dokku: Will my Heroku application run on it unchanged?

Usually. Dokku runs the same buildpacks and reads a Procfile, so the application layer normally moves across. Add-ons, scaling behaviour and backups are the parts you have to rebuild.

PostgreSQL: What is ACID compliance in PostgreSQL?

PostgreSQL has been ACID-compliant since 2001, ensuring data integrity through atomicity, consistency, isolation, and durability guarantees for all transactions.

Source

PostgreSQL: Does PostgreSQL support JSON data?

Yes. PostgreSQL supports JSON and JSONB data types for storing and querying JSON documents, along with XML and other document formats.
