Dokku Review (2026): Pricing, Features & Honest Verdict

TLDR

Dokku is a free, open-source, self-hosted PaaS that brings Heroku-style git push deployments to any VPS. Best for: solo developers and small teams who want full control over hosting. Price: free forever. Rating: 8.2/10

What is Dokku?

Dokku bills itself as the smallest PaaS implementation you will ever see. It is a Docker-powered platform that turns any Ubuntu server into your own private Heroku. You push code with git, and Dokku handles building, deploying, and managing your applications. The project has been around since 2013 and remains one of the most popular open-source PaaS solutions on GitHub.

At its core, Dokku uses Docker containers and Heroku buildpacks (or Dockerfiles) to package and run your apps. It supports zero-downtime deploys, process scaling, and a plugin ecosystem that covers databases, caching, and more. The entire system runs on a single server with surprisingly modest resource requirements.

Key Features

Git Push Deployment

The signature feature. Add a git remote, push your code, and Dokku detects the language, builds the container, and deploys it. The workflow is identical to Heroku. You get build logs in your terminal and the app is live within seconds of a successful build. It supports Heroku buildpacks, Cloud Native Buildpacks, and plain Dockerfiles.

Plugin Ecosystem

Dokku ships with official plugins for PostgreSQL, MySQL, MariaDB, Redis, Memcached, MongoDB, RabbitMQ, and more. Each plugin manages its own Docker container, handles backups, and links to your app via environment variables. Community plugins extend functionality to things like Let’s Encrypt SSL, HTTP auth, and maintenance mode.

SSL and Custom Domains

The Let’s Encrypt plugin makes SSL completely automatic. Point your domain, run one command, and certificates are issued and renewed without intervention. Multiple domains per app are supported, and wildcard certificates work too. The built-in nginx proxy handles all the routing.

Process Management

Dokku reads your Procfile (just like Heroku) and runs each process type in its own container. You can scale web workers, background jobs, and cron tasks independently. Zero-downtime deployment checks that the new container is healthy before swapping traffic over.

Resource Controls

You can set memory and CPU limits per app, which is essential when running multiple applications on a single server. Resource reports show current usage across all deployed apps, making capacity planning straightforward.

Pricing

Dokku is completely free and open source under the MIT license. There is no paid tier, no enterprise edition, no usage limits. Your only cost is the server itself. A $5-10/month VPS from any provider is enough to run several small applications. The project is maintained by Jeff Lindsay and funded through GitHub Sponsors.

Pros and Cons

Pros

• Truly free with no artificial limitations or hidden costs
• Heroku-identical workflow makes migration painless
• Tiny resource footprint, runs well on 1GB RAM servers
• Mature project with over a decade of active development
• Plugin ecosystem covers all common databases and services

Cons

• Single-server only, no built-in clustering or high availability
• CLI-only interface with no web dashboard
• Initial server setup requires some Linux knowledge
• Debugging failed builds can be frustrating without Heroku’s support team

Who Should Use Dokku?

Dokku is perfect for indie developers, freelancers, and small teams who are comfortable with the terminal and want Heroku’s developer experience without the monthly bills. If you are deploying side projects, client work, or internal tools and you want full control over the infrastructure, Dokku delivers. It is also a great choice for developers migrating off Heroku after their free tier changes.

If you need multi-server clustering, a web UI, or managed infrastructure with an SLA, look elsewhere. Dokku is proudly simple and single-server by design.

Alternatives

Coolify

Coolify is a newer self-hosted PaaS with a polished web dashboard, multi-server support, and built-in database management. It targets users who want a visual interface rather than CLI-only workflows. More feature-rich but also more resource-hungry than Dokku.

CapRover

CapRover offers one-click app deployment with a web UI and Docker Swarm clustering. It has a marketplace of 100+ pre-configured apps. Good middle ground between Dokku’s simplicity and a full orchestration platform.

Heroku

The original inspiration for Dokku. Heroku is fully managed with zero server maintenance, but paid plans start at $5/dyno/month and costs scale quickly. Best for teams that prioritize convenience over cost control.

FAQ

How much server resources does Dokku need?

Dokku itself uses around 256MB of RAM. A 1GB VPS can comfortably run Dokku plus a couple of small apps. For multiple apps with databases, 2-4GB is recommended.

Can I migrate my Heroku app to Dokku?

Yes. If your app uses a standard Procfile and Heroku buildpacks, migration is straightforward. Add the Dokku remote, push your code, and set your environment variables. Most apps work without code changes.

Does Dokku support Docker Compose?

Not directly. Dokku uses its own plugin system for services rather than Docker Compose. Each database or service runs as a separate linked container managed through Dokku CLI commands.

Is Dokku production-ready?

Yes, thousands of companies run production workloads on Dokku. The main limitation is single-server architecture, so you need to plan for server-level redundancy separately if uptime is critical.
