Backspace
Copyright (c) 2026 Jannis Braun
Backspace is free and open source software under the GNU Affero General Public
License v3.0 (AGPL-3.0-only); see the LICENSE file. A separate commercial license
is also available; see LICENSE-COMMERCIAL.md.
It bundles, depends on, or redistributes the third-party components listed
below. Each remains under its own license.
================================================================================
Fonts
================================================================================
DM Sans
Files: packages/web/public/fonts/DMSans-Variable.woff2
packages/web/public/fonts/DMSans-Variable-Italic.woff2
License: SIL Open Font License, Version 1.1
Notice: Copyright 2014 The DM Sans Project Authors
(https://github.com/googlefonts/dm-fonts)
The full license text is shipped alongside the font files at
packages/web/public/fonts/OFL.txt.
================================================================================
Sound effects
================================================================================
In-app sound cues (packages/web/public/sounds/*.ogg) are original works
authored for the Backspace project and are covered by the project license.
================================================================================
Icons and brand assets
================================================================================
The Backspace name, logo, and app icons (assets/brand/,
packages/web/public/icons/, packages/desktop build resources) are original
works and trademarks of the project. Neither the AGPL nor the commercial license
grants any right to use these trademarks; trademark use is governed separately by
applicable law.
In-application UI icons are hand-authored inline SVGs and are covered by the
project license.
================================================================================
npm dependencies
================================================================================
Backspace depends on open-source packages distributed via npm, all under
permissive licenses (predominantly MIT, ISC, Apache-2.0, and BSD variants).
The image-processing dependency "sharp" loads libvips, distributed as a
prebuilt binary under the LGPL-3.0-or-later license; it is used unmodified and
dynamically, and is not statically linked into Backspace.
To regenerate the full, current dependency license inventory, run:
pnpm licenses list --prod
================================================================================
Emoji
================================================================================
Emoji selection is provided by @emoji-mart/data and @emoji-mart/react (MIT).
No emoji glyph images are bundled; glyphs render using the host operating
system's emoji font.
