Free WYSIWYG Markdown editor

I've been using Typora as a Markdown editor when it was free (during beta), but now it's pay for use and I want to find an equivalent, free (preferably open source) tool. **My requirements**: - free (preferably open source) - rather than a separate editing and preview pane, I want the editing to happen in the same pane in which the Markdown code is rendered, i.e., WYSIWYG. This is what Typora does - support for drawing tables, bulleted/numbered lists, code fences, import images, etc. Basically, the same features as the post editor on Stack Exchange, but WYSIWYG instead of separate editing/preview panes - rendering of math formulas - runs on Monterey **Research**: I googled around a bit and I found the following; - Mou app seemed to have been widely recommended in the past, but it's not being developed anymore (and anyway it cannot be downloaded, since the site is down) - MacDown is active, but it has separated editing and rendering panes - similarly for VS Code
