Markdown that gets out of the way.
A native, GPU-rendered editor for macOS. Syntax folds away as you write.
Plain CommonMark on disk — always.
Free & open source · Apache-2.0 · Apple Silicon · ~15 MB
**Markers hide** until your cursor touches them, then reveal in place. Headings, lists, quotes, links, checkboxes — styled live, raw on demand.
Tables render as real tables and images render inline while you edit. Touch one and it dissolves back to source.
Tree-sitter highlighting in fenced blocks and standalone files. Code files get a real editor: gutter, auto-indent, monospace, full width.
Six built-in themes with a live ⌘T picker — or drop your own TOML in ~/.supermd/themes. Light and dark follow the system.
Autosave with atomic writes, per-session backups, and external-change detection that never silently clobbers anything.
Rust on GPUI — the GPU-accelerated framework behind Zed. Instant startup, 120 fps scrolling, a ~15 MB download.
No database, no lock-in, no export step. SuperMD edits the Markdown files already in your folders — and they stay exactly that.
