Markdown is super useful for software development, and now I want to use it for my notes too. The problem is, I don’t know of any note-taking apps that support Markdown with GitHub-like features, like linking images from a folder or the web, header links, GitHub’s extra Markdown extensions, color-coded code blocks, or even using HTML along with Markdown.
Obsidian.md is a great choice. It has a huge community, and if you want to go beyond the basic features, there are tons of plugins available.
This. In actuality, there is no competition.
yeah…By far the best 
Logseq, for me is the best. Obsidian is nice too
For offline Markdown note-taking with lots of flexibility, check out Obsidian or Typora. Both let you link images, use header links, and have advanced Markdown features. Obsidian offers tons of customization and handles HTML too. Typora is easy to use and supports various Markdown extensions and formatting. Both give you a GitHub-like experience.
I’ve been using Obsidian for a couple of years now and it’s been awesome
I use Typora. It is affordable and the best md editor I’ve ever used.
Obsidian without a doubt.
