Linkwarden has pretty minimal hardware requirements - it was tested on a VPS with 4gb of memory and it ran pretty smoothly, the most intense part is when you build the app, but once it's running it's relatively lightweight.

From their website. I wouldn't consider tested on 4gb vps having minimal hardware.

I use Linkding and I am very happy with it. Less feature? Maybe. But it's a bookmark sync. What do you need?

It's intensive because its trying to archive the links and spends a lot of ram doing so.

It's more like a replacement for pocket.

Before I started to host a bookmark service i made some investigation, and the final dockerized contenders in 2023 for what relates to memory were:

Shaarli: (~ 50Mb of RAM )

Shiori: ( ~30Mb of RAM but lacks quite some features)

linkding ( ~200Mb of RAM)

In the end i went with Shaarli

I guess my question would be what are your resources?

Runs smooth on my old qnap 453 :]
