Comparison
Phelix vs Coolify
Coolify is a broad, container-based self-hosted PaaS. Phelix is a native Go and Rust deploy tool that needs no Docker. They solve different shapes of problem; here is where each one fits.
Released Phelix hosts: Linux and macOS. Builds Go and Rust with your host toolchain.
Where each fits
Start from what you are running, not from a feature count.
Reach for Coolify when you want a UI-driven platform to run many kinds of applications, databases, and services from Git, in containers, on your own servers. Its breadth and one-click catalog are the point.
Reach for Phelix when you specifically run Go and Rust services and want native binary builds with health-gated zero-downtime deploys and one-command rollback, driven from a CLI, without adopting Docker as the unit of deployment.
Coolify details here reflect its public documentation and comparisons as of September 2026. Both tools change, so verify current behavior before you decide.
Side by side
A neutral capability comparison, not a scorecard.
| Capability | Phelix | Coolify |
|---|---|---|
| Primary model | Native Go and Rust binaries, one CLI plus a per-host agent | Container-based self-hosted PaaS with a web UI |
| Build inputs | Go and Rust, compiled on the host toolchain | Nixpacks auto-detect, Dockerfile, Docker Compose, or a prebuilt image |
| Docker required | No; binaries run directly, Docker image build is optional | Yes; deployments run as containers |
| Zero-downtime deploys | Blue-green, rolling, and canary with health-gated proxy cutover | Available for Dockerfile, Nixpacks, and single-image deploys; not for Compose stacks as of this writing |
| Rollback | Native rollback to a retained version through the current topology | Redeploy a previous deployment |
| Databases and services | Not provided; Phelix deploys your applications | Managed databases and a large one-click service catalog |
| Interface | CLI-first, with an optional dashboard | Web UI |
| Language scope | Focused on Go and Rust | Many languages and stacks |
What Phelix does differently
The native-binary path, end to end.
Phelix builds your Go or Rust source into a numbered native binary and supervises that process directly, so there is no container layer to reason about. Deploys are health-gated at the process and proxy level, and the full strategy set lives in deployment strategies and zero-downtime deploys.
Environment values are encrypted at rest with AES-256-GCM using a local key, and each build carries its own snapshot, so rollback restores the binary and its configuration together.
Where Coolify is stronger
Breadth, databases, and a web-first workflow.
If you need managed databases, a large catalog of one-click services, support for many languages and frameworks, or a full web UI for a mixed fleet of apps, Coolify covers ground Phelix intentionally does not. Phelix operates applications on infrastructure you already control and does not provision servers, manage databases, or run a service marketplace.
One binary between git push and production.
Install the CLI, verify the host, and follow the quick start to build your first application.
