Licenses & attribution.

The OneKit core is licensed under Apache-2.0. Third-party components retain their own licenses and copyright notices.

Pyodide 314.0.7

This site loads the unmodified Pyodide runtime directly from jsDelivr, licensed under MPL-2.0. Read the license. The corresponding source is available at the exact Pyodide release tag. New files written for OneKit are separate from Pyodide.

PDF.js 6.4.299

Visual page previews use Mozilla PDF.js under Apache-2.0. The viewer is downloaded directly from jsDelivr only when a PDF preview is requested. Files remain on your device.

CPython

Pyodide includes CPython. Its original notices are preserved in the Python license; the corresponding version is recorded in the runtime lock file.

Inter

Inter is used under the SIL Open Font License 1.1. Read the font license. The unmodified font is downloaded directly from jsDelivr.

GitHub icon

The GitHub mark comes from Primer Octicons, copyright GitHub Inc., under the MIT license.

Processing packages

Tool-specific Python packages are obtained from their upstream distribution services as the selected workspace prepares or runs. The pinned browser dependency manifest records the versions. PDF processing uses pypdf (BSD-3-Clause), images use Pillow (MIT-CMU), documents use python-docx and python-pptx (MIT), spreadsheets use openpyxl (MIT), encryption uses PyCryptodome (BSD and public domain), and font processing uses fontTools (MIT). Their original notices remain part of their packages.

External CLI engines

Optional engines such as LibreOffice, FFmpeg and Pandoc are installed separately by CLI users. They are not included in the OneKit wheel, source download or initial Docker image. Their license obligations are documented in the engine guide.
