DevPod is basically Vagrant but with containers, which brings a ton of benefits over the former VM-centric design. You can maintain an entire team (or organization) with one immutable development environment, to get away from the constant toil of fixing random problems on random people's dev environments that happened because they changed something locally and don't have an immutable environment to restore.

The fact that it's self-hosted means you can take it anywhere (your laptop, GCloud, AWS, Azure, etc). Containers means you can save resources or scale it, reuse public containers and container ecosystem tools. Unopinionated means you aren't forced to use one IDE or platform. Open Source means you can read the source to figure out what's going on and hack in a solution if needed.

This one is still early days it seems, as it doesn't run on my Mac (I opened an issue). But the benefits once it works will be incredible. I've been trying to onboard our teams to Devspace, which has its warts [and lack of docs], but is still lightyears better than most other solutions. Once DevPod is stable I'll be looking into moving to it.
