That's just lip service, either you intend to or you don't, it's not up to hope

We hope you will see the dev tooling space is based around open source and you will alienate many potential users by not being open source

Let me know when it's open source and I'd be happy to give it a try! It doesn't even have to be free - I'm fine with Unreal's model where you get access to the source even though commercial use requires a paid license.

I want something running locally on my machine that doesn't rely on calling home.

your concern is understandable. we'll be in touch :)

Give me one reason to use a closed-source Redis alternative rather than one of many open ones, starting with KeyDB. If I wanted a closed clone, I'd probably go with DragonflyDB (whose license is "feel free to run it in production unless you offer it as a managed redis service").
