Selfhosting
Selfhosting is where you're hosting your own websites, apps, software, tools, and much more on your own server instead of having to rely on 3rd-party cloud providers such as Hetzner. Taking this approach to hosting gives you more control over your data and how your server or servers are managed.
When you are running multiple things on one or two servers, within your home, it's called a "Homelab" and you're "Homelabbing" at that point.
Running your own server and homelab within your home is great for privacy-conscious individuals such as myself, tech enthusiasts, small businesses, and those seeking more control of their digital life.
The following lists provided here are applications and software I've gotten comfortable with and enjoyed using over the past 3 and a half years since I started homelabbing, it's based on my experience and what fits my criteria. Some well known softwares won't be listed here, as my experience may of not been at best with them.
My criteria is that software is built in the open, respects user privacy and security, should not require a license to operate, and don't contain profanity and other minor things.
I'm also willing to test new software to selfhost, feel free to comment or message me to try out other alternatives.
There are other places to check out as well for those interesting selfhosting, such as Awesome Selfhosted, selfh.st, and other places you can find on the internet.

If you ever need help with selfhosting, you can check out the following communities:
Homelab Community on Fluxer, I personally run
/r/selfhosted (Reddit)
/c/selfhosted (Lemmy / Fediverse)
There's also a wiki you can look into as well.
If you believe an alternative software should be added to this list, please contact me or direct message via my AlternativeTo account. I'm also available on Signal.
This lists gets updated every month at least, check back regularly.

PoW does not stop bots, it only slows them down.
PoW is great to fight spam, however I wonder how this perform on mobile. Today mobile browsing is huge and the UX of PoW would kill the batteries fast no ?
Only if the PoW was difficult. Most PoWs in CAPTCHA products are completed in seconds and do not deter bots. You need dynamically adapting PoW products like Procaptcha to stand a chance of stopping bots, as opposed to just slowing them down.
