Dokku Alternative: app.nz
Dokku is a strong cloud hosting option. Dokku is a lightweight open-source PaaS that brings Heroku-like git push deployment to your own server.
This comparison is written with respect for Dokku. The point is not that one product is universally better. The question is which scope you want: a focused specialist, or one place where agents, deploys, model routing, GPU workloads, and app hosting live together.
Where Dokku is strong
- Small, understandable, and self-hosted.
- Great for developers who want Heroku-like deploys on one VM.
- Low abstraction compared with larger platforms.
Where app.nz is different
app.nz is broader than a single hosting product, gateway, or coding assistant. It combines:
- cloud coding agents that can work on repos and hand back durable diffs
- static sites, server deploys, private container builds, domains, logs, queues, and secrets
- one OpenAI-compatible model gateway for text, image, video, audio, embeddings, search, and 3D
- scale-to-zero GPU hosting for Cog and Comfy workloads
- one credit balance and API surface across the product instead of separate tools for every layer
app.nz is for teams that want the platform to own more of the AI workflow: agents, model routing, GPU hosting, static and server deploys, queues, and logs.
Choose Dokku when
Choose Dokku when you want to own the server and keep deployment mechanics simple.
Choose app.nz when
Use app.nz when you want the development loop and the runtime loop in one system: ask an agent to work on code, build or deploy the result, route models through the gateway, host GPU endpoints when needed, and keep operational primitives like queues, logs, domains, datasets, notebooks, and billing close to the same account.
Migration path
Move the apps that need AI gateway, GPU, or agent integration first; leave simple self-hosted services on Dokku if they are working well.
Bottom line
Dokku is a good product for its lane. app.nz is the alternative when the lane is too narrow and you want an AI agent cloud that also hosts the application, routes the models, and runs the GPU or worker infrastructure behind it.
