I use Obsidian all the time, but this free, self-hosted notes app might be even better

Obsidian has been my go-to for a while now when it comes to note-taking, and for good reason. It's well laid out, it's easy to use, and it's completely free for both personal and commercial use. Even paid features like Obsidian Sync, which you can use to synchronize notes to other devices, can easily be replaced by managing the synchronization between your devices yourself. With that said, I've recently been using a lesser-known self-hosted note-taking app called Blinko, and it's slowly replacing Notion for me.
