I am fairly new to Lemmy and was thinking of getting an account on one of the “big” servers to get the full experience, but then I figured I could do exactly the same thing as with my GoToSocial and other services: run my own instance.
I am wondering if this is an overkill or not. Any experience running your own small Lemmy instance? Are there better options that are compatible with Lemmy but lighter to run for this purpose?


YuNoHost is a great alternative, but if you really want to learn, I would instead recommend really spending some time learning Docker; you don’t have to understand how to build your own images (although that is also very useful), but mostly what is going on at a high level, and then switch to Docker Compose. These days it is extremely easy to run very complex architectures with a single compose file.
You also don’t need to make it public for your tests, you can always start with local ip addresses and you own computer, or if you have a small computer that can run headless, then you can setup your experiments in there.
