Docker Desktop is the default for running containers on a local machine, but it is no longer the only choice. Rancher Desktop and colima are the two main alternatives, and the right one depends on the team’s needs.

What Docker Desktop does
Docker Desktop is the Docker company’s macOS and Windows product for running containers locally. It bundles:
- The Docker engine.
- The Docker CLI.
- The Docker Compose.
- The Kubernetes control plane (optional).
- The Docker extension marketplace.
The product is free for personal use and small businesses; commercial use requires a paid subscription.
What Rancher Desktop does
Rancher Desktop is the SUSE open-source alternative to Docker Desktop. It bundles:
- The containerd or dockerd engine (the team’s choice).
- The Docker CLI.
- The Kubernetes control plane (the team’s choice of version).
- The kubectl CLI.
The product is free for all use, including commercial.
What colima does
colima is the community open-source alternative. It bundles:
- The Lima VM (a Linux VM on macOS).
- The containerd or dockerd engine.
- The Docker CLI.
- The Kubernetes control plane (optional).
The product is free for all use. It is the simplest of the three for the team that just needs to run a few containers locally.
The trade-offs
The trade-offs the team needs to understand:
- Docker Desktop: the most polished UI, the best extension marketplace, the most documentation, the most tutorials. The cost: a paid subscription for commercial use, and the recent licensing changes have made it less attractive.
- Rancher Desktop: open-source, free, full Kubernetes support, multiple engine choices. The cost: a less polished UI, fewer extensions, and the team has to know which engine to pick.
- colima: the simplest, the lightest, the most Unix-y. The cost: less documentation, fewer features, the team has to know how to use the command line.
When to use Docker Desktop
The team that should use Docker Desktop:
- The team that wants the most polished UI and the best extension marketplace.
- The team that is willing to pay the subscription for commercial use.
- The team that does not need Kubernetes (or only needs it as a learning exercise).
When to use the alternatives
The team that should use Rancher Desktop:
- The team that wants a free, open-source alternative to Docker Desktop.
- The team that is running Kubernetes in production and wants the local cluster to match the production cluster.
- The team that is comfortable with a less polished UI in exchange for the cost savings.
The team that should use colima:
- The team that wants the simplest possible setup.
- The team that is comfortable with the command line.
- The team that is on a Mac and wants the lightest possible footprint.

If you are setting up a local development environment for a new project, the RunxBuild hosting calculator is the place to model the line items. The containers, the volumes, the CPU, the memory - each one is a separate number, and the team’s mental model for the platform is the sum of those numbers. The RunxBuild dashboard is where the team sees the production deployment in one place.
