Paying for sync is absolutely fine as long as the client is open source. Thanks for the logseq recommendation, it looks very good from the first sight! I only wish they had NeoVim plugin like Obsidian has.
Agreed, I pay for logseq sync. Down below someone mentioned doing it with sync thing, but paying is easier for me, and supports development to boot. There is a logseq plugin for vi-like keybindings, but predictably, it's just meh. Hope you enjoy logseq, it's amazing.
I have never used this, but for NeoVim it looks like you might be able to use this (or hack on it a bit to make it work with LogSeq a bit better) https://github.com/artempyanykh/marksman
