Ideally for your router you want something that runs an open source firmware (OpenWRT, DD-WRT, OPNSense, FreshTomato). Its better because you get a completely unlocked everything you need system with security patches for the hardware’s true lifetime. Every router company stops with the security updates after a few years and then at some point it becomes part of a bot net or one of this mass hack events. Its best not to play in that game and instead run some open source firmware from the outset.

The best way to start is to look at the website for openwrt.org and use their filtering to find a device that supports your needs (at least 5 LAN ethernet ports I guess and some wifi but AC sounds like it will do). The other option is a more typical 4 LAN port router which will give you a lot more options and then add a switch to that, doesn’t sound like you care too much about it being managed or >1gbps so they are also dirt cheap.

Metube is great and also has some browser plugins as well so it’s as simple as right click and send to metube on a YouTube link. Wish there was one for android too but alas not yet that I have seen.

I don’t think modern Raspberry pi’s make much sense unless you are using GPIOs or really need the low power consumption. The 3 and the 4 were OK price wise but the pi 5 is quite close to all these N100 mini computers and they are a lot more performance and expansion compared to a raspberry pi 5 and still quite low power.

Either a Topton or similar N100 based machine or a mini PC second hand is the way to go at the ~$100 mark. The mini PC will be faster and probably more expandable and cheaper but also more power consumption.

Another possibility for cheap VPS is Contabo they are quite good value. Netcup is good value as well.

I used Invidious for about a year and it was a constant string of bugs. Every release was a risk and quite often updates would get lost or the database would explode in size and consume all the drive space. Its not a project I currently use or recommend until it stabilises.

Hugo? As in your generated site or you have some sort of service that costs hugo that generates and deploys your site or something else?

It has been slowly improving. It used to be a lot worse but I have a lot less issues with it now than I did before all the changes. Its not the fastest best way to do anything, there are better calendar, file sync, email etc etc applications out there in every category that run better but its also quite an easy way to make a lot of things happen.

The new Linuxserver.io docker image at the very least has solved the annoying update cycle NextCloud has and seems to have fixed the need to do that every few months. I haven’t ever had it die but I don’t push it hard and I keep the plugins to a minimum because I just don’t trust it and it doesn’t run all that well.
