Manifest Chess Lite source code on GitHub, GPL-3.0-or-later

Read every line

Manifest Chess Lite is open source under the GPL. The complete source for the app you install from the Mac App Store is public: read it, build it, change it, or send a patch.

The fast, fully offline PGN reader for Mac. The repository holds everything the app is made of: the board and the move list, the PGN reading and writing, the engine wiring, the Quick Look preview, and the build that produces the App Store release.

Issues and pull requests are open. If you have found a bug or want a feature, the issue tracker explains what to include.

What open source means here

Your right to install, run, copy, modify, and redistribute Manifest Chess Lite comes from the licence, not from us. It is not limited to non-commercial use, or to a set number of Macs.

Read it, and build it

The repository holds the complete source for the app on the Mac App Store. Clone it, read it, and build your own copy.

Change it, and pass it on

You can modify Lite and share your version, as long as it goes out under the same licence and with its source.

What the purchase buys

The App Store price buys the signed, ready-to-run build, updates through the App Store, and support. The licence gives you the source either way.

The full licence text ships inside the app, under Manifest Chess Lite then About, and sits in the repository as LICENSE.

Stockfish, Chessground, and chessops inside the PGN reader

Built on other people's work

Lite ships open source components from other projects, each under its own licence and with its own source. The app credits them under Manifest Chess Lite then About, and the repository lists every file and asset in COPYING.md.

For the complete list, including every board, piece set, and sound pack with its author and licence, see COPYING.md in the repository.
