Where each one falls short

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

Confluent Cloud

  • Requires understanding of eCKU (Elastic Confluent Unit) billing
  • Data in/egress costs add $0.014-$0.050 per GB
  • Storage costs of $0.03-$0.08 per GB-month
  • Minimum commitment recommended for cost optimization

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

Confluent Cloud pricing starts free on Basic tier with $0.14 per eCKU-hour, Standard at $0.75 per eCKU-hour (~$385/month base), Enterprise at $1.75-$2.25 per eCKU-hour (~$895/month base), and Freight specialty tier at $2.25 per eCKU-hour (~$2300/month).

Source
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.

Confluent Cloud: Is there a free tier for Confluent Cloud?

Yes, the Basic tier is free with one eCKU credit included. Additional usage is billed at $0.14 per eCKU-hour, plus data transfer and storage fees apply.

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.

Confluent Cloud: What additional fees does Confluent Cloud charge?

Beyond eCKU hours, Confluent charges data in/egress at $0.014-$0.050 per GB and storage at $0.03-$0.08 per GB-month. Costs vary by tier and region.

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.

Confluent Cloud: Does Confluent offer discounts for higher usage?

Yes, volume discounts are negotiated upfront based on annual consumption estimates. Annual commitments allow flexible cross-product allocation with guaranteed cost savings.

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.
