Open Source Notices
This page identifies the license for PrismNext and the principal third-party components bundled in official installers. It restates the repository NOTICE and LICENSE for readers of this website.
1. PrismNext source code
Copyright 2026 yibocat. The PrismNext source code is licensed under the Apache License, Version 2.0. You may obtain a copy of the license in the repository LICENSE file.
Unless required by applicable law or agreed to in writing, software distributed under the License is distributed on an “AS IS” BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the License for the specific language governing permissions and limitations under the License.
Redistribution and modification of the source code are governed by that license, not by the Terms of Use for the official installer. If the two conflict on source-code redistribution, the Apache License controls.
2. Bundled components in official installers
Official binary distributions include the following third-party components. Each remains
under its own license. The versions pinned for a given release are recorded in the
repository (for example scripts/tectonic-version.txt).
| Component | Role in PrismNext | License |
|---|---|---|
| Electron | Desktop application shell. Official installers therefore also include Chromium and Node.js as part of that framework. | MIT — electron/electron |
| Tectonic | Default bundled TeX/LaTeX compile engine. | MIT — tectonic-typesetting.github.io |
| PDF.js | Built-in PDF reader, including viewer resources (cmaps, standard fonts, wasm, iccs). | Apache-2.0 — mozilla/pdf.js |
| OpenTikZ | Vendored TikZ catalog (templates and examples) used by the figure-tikz skill. Brand marks inlined in a few templates remain trademarks of their owners. | CC0 1.0 — opentikz/opentikz |
3. Other dependencies
JavaScript and native modules declared in package.json /
pnpm-lock.yaml carry their own licenses. The repository NOTICE does not
attempt to enumerate them. Chromium, as shipped by Electron, is subject to the licenses
distributed with that framework.
4. Pro modules
Certain official builds include Pro modules. Those modules, when present, are unlocked by a local activation key as described in the Terms of Use. They are not a transfer of source code and are not covered by the Apache License that applies to the open-source core.
5. Obtaining the texts
The authoritative copies in the source repository are:
Upstream projects publish their own license texts. If a summary on this page differs from an upstream file, the upstream file controls for that component.
