Open-source components & source code

Nullprint's browser kernels are built from open-source projects. This page lists them, their licences, and where to get the source we are required to provide. It applies to every Nullprint release published so far and is updated with each new kernel.

1. Chrome kernels (Chromium)

Built from Chromium (BSD-style licence) and the third-party components it includes, each under its own licence. The full copyright and licence notices for each kernel line:

Chrome 154 (154.0.8037.57, all releases): credits (HTML)
Chrome 152 (152.0.7977.82, all releases): credits (HTML)
Chrome 148 (148.0.7778.215, all releases): credits (HTML)
Chrome 144 (144.0.7559.132, all releases): credits (HTML)

Chromium source: source.chromium.org.

2. Firefox kernel (Mozilla Firefox + Camoufox)

The Nullprint Firefox kernel is based on Camoufox and Mozilla Firefox, licensed under the Mozilla Public License 2.0. If you have received the Nullprint Firefox kernel and would like the MPL source files we have modified, email support@nullprint.ai and we will provide them within a reasonable time, free of charge. Please mention the kernel version (shown in the kernel's About window, e.g. 156.0.1-lt3).

The unmodified upstream sources are published by Mozilla at archive.mozilla.org and by the Camoufox project at github.com/daijro/camoufox.

Firefox is a trademark of the Mozilla Foundation. The Nullprint Firefox kernel is not Firefox and does not use the Firefox name or logo; its icon is derived from Mozilla's unbranded-build artwork (MPL-2.0). Chromium is an open-source project; Chrome is a trademark of Google LLC.

3. Desktop app and background service

The Nullprint desktop app (built on Electron) and its background service include open-source libraries under their own licences. The full list with versions and licence texts: third-party notices.
