Znote
Markdown notes with runnable code blocks for developers.
Znote is a desktop note app for developers whose defining feature is executable notes: JavaScript, Python, and other code blocks inside your markdown can actually run, turning notes into lightweight notebooks.
Alongside that it offers standard markdown editing with live rendering, local plain-file storage, tags and search, and optional sync — notes that double as small automation scripts.
