Why is this shit so complicated?

Because container tools are built by infrastructure engineers who think normal people enjoy editing YAML files at 2am. Podman Desktop tries to hide this complexity but then you hit edge cases and suddenly you're debugging VM networking.

Which one actually works without 3 hours of setup hell?

[OrbStack](https://orbstack.dev/) if you're on macOS and can pay $8/month. [Finch](https://runfinch.com/) if you want something free that doesn't break constantly. Everything else requires some level of configuration pain. The [Finch installation guide](https://runfinch.com/docs/installation/) is literally `brew install finch && finch vm init` - that's it. [OrbStack setup](https://orbstack.dev/docs) is drag-and-drop installer plus clicking "Migrate from Docker Desktop" button.

Will my Docker Compose files still work?

Probably. OrbStack and Finch handle 95% of Compose files without changes. [Colima](https://github.com/abiosoft/colima) works but occasionally chokes on volume mounts with spaces in paths. Test your specific setup before switching completely.

What breaks when I upgrade macOS?

Colima breaks every major macOS update. You'll see `Error starting colima: unable to start VM: lima crashed` and need to reinstall. OrbStack usually survives updates because it uses [Apple's Virtualization Framework](https://developer.apple.com/documentation/virtualization). Rancher Desktop might need a restart but usually works. Podman Desktop... well, that's why you're here. After Sonoma 14.4, I got `Failed to start podman: exit code 125` for a week until they pushed a fix.

Is it worth switching or should I just stick with what works?

If Podman Desktop works for you, don't switch. Seriously. These alternatives solve specific problems (speed, memory usage, Kubernetes integration). If you don't have those problems, switching is just work.

Which tool for teams on a budget?

[Colima](https://github.com/abiosoft/colima) is free and fast when it works. [Finch](https://runfinch.com/) is more reliable but slightly slower. Avoid anything requiring per-user licenses if you're watching costs.

What about Windows users?

[Rancher Desktop](https://rancherdesktop.io/) works best on Windows with WSL2. [Finch](https://runfinch.com/) is also decent. Most other tools are Mac/Linux focused. Windows container development is still kind of a mess regardless of tool choice.

Do I need Kubernetes support?

No, you probably don't. 90% of projects using Kubernetes are over-engineering simple problems. If you actually deploy to Kubernetes in production, [Rancher Desktop](https://rancherdesktop.io/) is worth the RAM usage. Otherwise, skip the K8s overhead.

What if I just want Docker commands to work faster?

OrbStack on macOS. Colima on Linux. Both make containers start in 2-3 seconds instead of 20+ seconds. The speed difference is real and saves significant time during development.

Which tool won't make me want to throw my laptop?

[Finch](https://runfinch.com/). It's boring but reliable. Works the same way every day for months. No surprises, no random configuration changes, no weekend debugging sessions.

Can I run multiple tools at the same time?

You can install multiple tools but only use one at a time. Having OrbStack and Colima both running will cause port conflicts and general weirdness. Pick one and stick with it.

What happens to my existing containers and volumes?

OrbStack and Rancher Desktop try to import existing stuff automatically. Works maybe 70% of the time. For CLI tools, you'll need to export images (`docker save`) and manually recreate volumes. Plan for a few hours of migration work.

How do I know if something is broken?

If containers take longer than 10 seconds to start, something's wrong. If you're getting random networking errors, something's wrong. If you're spending more time configuring the tool than using it, definitely something's wrong. Specific red flags: `docker: Cannot connect to Docker daemon`, containers taking 30+ seconds to start, or seeing `podman machine restart` in your bash history more than once per week. When your terminal autocomplete shows more debugging commands than actual work commands, it's time to switch.
