No Electron, no Tauri, no WebView. speedmark draws its own window with egui and talks straight to the operating system.

A lean Rust release build with LTO. The window is on screen before a browser engine would have finished booting.

There is no browser engine inside the process, so it needs a fraction of the RAM other editors ask for.

Type Markdown and watch it format itself. No split preview pane, no modal window.

Plain .md files on your disk. No account, no sync server, no lock-in.

Make it yours

Theme, body size, CJK fallback font, interface language and panel visibility — no config files, no restart, applied the moment you click.

Light, dark, or follow the system
Three theme modes with light and dark previews, so you can see the switch before you make it.
Body size scales editor and preview together
One slider keeps the source and the rendered document aligned as you resize.
Pick the CJK fallback font
Latin text uses the bundled HarmonyOS Sans; CJK characters fall back to whichever font you choose.
Interface language: English or 中文
Every label switches immediately — the document you are writing is never touched.
Collapse the panels you do not need
File tree, outline and preview toggle independently, so the editor can take the whole window.

One-time purchase. Pay once, keep it.
