Credits

Third-party assets bundled into the app, with their licenses.

Icons

• Bootstrap Icons — the titlebar sidebar-toggle glyph, the file-tree document glyph, and the titlebar title's per-type file glyphs (markdown / blank / text). © The Bootstrap Authors. Licensed under the MIT License. https://github.com/twbs/icons/blob/main/LICENSE

• MingCute Icon by MingCute Design — the file-tree folder and caret glyphs, the titlebar new-file glyph, and the Windows-style window controls (minimize / maximize / restore / close). Licensed under the Apache License 2.0. https://github.com/Richard9394/MingCute/blob/main/LICENSE

Theme fonts

Fonts bundled with the built-in themes (packages/workbench/src/themes/builtin), carried over from Typora 1's themes.

• Open Sans (GitHub theme) by Steve Matteson. Licensed under the SIL Open Font License 1.1. https://github.com/googlefonts/opensans

• PT Serif (Newsprint theme) by ParaType. Licensed under the SIL Open Font License 1.1. https://fonts.google.com/specimen/PT+Serif/license

Libraries

Third-party code bundled into the renderer and the app process. Each entry keeps the attribution its license asks to be preserved.

• CodeMirror 6 (@codemirror/state, @codemirror/view, @codemirror/commands, @codemirror/language, @codemirror/lang-markdown, and the @lezer/*, style-mod and crelt packages they pull in) by Marijn Haverbeke — the Source Code Mode editing surface and its markdown parsing. Licensed under the MIT License. https://github.com/codemirror/dev/blob/main/LICENSE

• GSAP by GreenSock (Webflow) — the block transition in EditorView, via the Flip plugin. Not an open-source license: the Standard "No Charge" GSAP License (effective 2025-04-30) is proprietary, with ownership retained by Webflow and termination at their discretion. https://gsap.com/standard-license

  Its Permitted Uses cover "any website, web application, or digital interface," and its FAQ states that commercial use is free of charge, including plugins that were formerly members-only. Its Prohibited Uses are no-code visual animation builders competing with Webflow, which this is not. Restriction III.3 forbids removing GSAP's proprietary notices — the minified bundles keep all four (GSAP, CSSPlugin, matrix, Flip), verified in both the macOS and Windows builds.

  Note for upgrades: clause VI lets Webflow revise these terms, and continuing to use newer releases accepts the revision, while already-licensed versions may keep running under the terms they shipped with. So the pinned version is what a given set of terms attaches to.
