Markly is a free, open-source Markdown editor for macOS that edits themd files in folders you already have: no import, no database, no lock-in. Formatting renders as you type, and markers hide on lines you're not editing. Native SwiftUI + AppKit with Liquid Glass, no Electron. Format bar on selection, clickable tasks, one-click Git sync, focus mode, scroll-synced preview with math, HTML/PDF export. No accounts, no tracking.

Maker
Markly's website (markly.justghali.dev) is a Next.js 16 app deployed on Vercel. Git-push deploys with preview URLs let me, as a solo maker, iterate on the interactive editor demo and copy without touching any infrastructure. The site is prerendered and served from Vercel's CDN, the latest release version badge is fetched from GitHub and revalidated hourly with ISR, and the 1200Ć630 share image is generated on the fly with next/og. That meant I could spend my time on the macOS app itself and still ship a fast, polished landing page that always shows the current release.

Hey Product Hunt š
I'm Ghali, an indie maker from Bali. My notes are just a folder of .md files, some of them inside git repos. Most Markdown apps wanted me to import everything into their own library or database, and the lightweight ones felt like a text box with a preview bolted on. So I built Markly.
What it does:
⢠Point it at any folder and it edits your .md files in place. Files changed elsewhere (git, other editors) reload on their own.
⢠Everything renders as you type. Markers like ** and # collapse on lines you aren't editing and come back when the caret moves there.
⢠One-click Git sync from the sidebar: commit, pull (rebase) and push, scoped to your notes folder.
⢠Focus on paragraph, typewriter scrolling and a GitHub-style preview with KaTeX math, plus HTML/PDF export.
It's fully native (SwiftUI, AppKit and Apple's Liquid Glass), works offline, and has no accounts, analytics or tracking. It needs macOS 26 Tahoe, it's universal (Apple silicon + Intel), and it's MIT licensed.
Markly is free and always will be. I'd love your feedback: what's missing before it could replace your current Markdown editor? Next on the roadmap: image paste/drag, an outline panel, and full-text search.
