showmd

Showmd is a markdown preview tool, and honestly, the tagline really nailed it — "Markdown was never meant to be previewed plain text" hits because we've all been there, staring at raw .md files wishing they looked like the final render. It seems like a sleeper hit for developers and technical writers who've dealt with that specific pain point. The concept is simple but that's kind of the move — it's not trying to be a full CMS, just solving one annoying thing really well.
