Third-Party Notices

This page is for operators and contributors reviewing vendored browser assets and their licences.

OpenPost Image Editor uses these pinned runtime dependencies:

• Fabric.js 7.4.0 for interactive canvas objects, transforms, filters, and offscreen rendering. OpenPost persists its own versioned document schema rather than Fabric JSON.
• IMG.LY Background Removal 1.7.0 for local background removal.
• ONNX Runtime Web 1.21.0 for WebGPU and CPU inference.
• fflate 0.8.2 for multi-page ZIP downloads.

The quantized background-removal model, WASM files, and their notices ship under frontend/static/image-editor-models/. ThirdPartyLicenses.json, the model license, content-addressed resource filenames, and the source URL used for the pinned artifact are kept beside the files. Operators that set OPENPOST_IMAGE_EDITOR_MODEL_BASE_URL must serve the matching release assets and preserve their notices.

OpenPost Video Editor uses:

• Mediabunny 1.51.x for media inspection, bounded sample access, demuxing, streaming MP4/WebM muxing, and its MPL-2.0 ProRes extension with TurboRes for local ProRes decode.
• Transformers.js 4.1.0, with 3.8.1 used through Kokoro, and ONNX Runtime Web 1.26.0 development build for local worker-based analysis and generation.
• FreeCut source adapted under the MIT License. The retained license is in licenses/FREECUT.txt.
• LosslessCut informed Quick Cut interaction and stream-copy behavior. LosslessCut is GPL-2.0-or-later; OpenPost uses it as a behavioral reference only and includes no LosslessCut code, styles, or assets.
• Paper Shaders source adapted under the Apache License 2.0. Its retained license and notice are in licenses/PAPER_SHADERS.txt and licenses/PAPER_SHADERS_NOTICE.txt.
• Parakeet TDT 0.6B v3 under CC-BY-4.0 and Whisper Tiny, Base, Small, and Large v3 Turbo under the MIT License for local transcription.
• Kokoro 82M under Apache License 2.0, Supertonic 3 under its OpenRAIL terms, and MOSS Nano under Apache License 2.0 for on-device voice generation. Supertonic and both MOSS repositories use fixed revisions. The MOSS browser runtime, model revisions, download sizes, and retained MIT and Apache terms are recorded in frontend/static/moss-tts/THIRD_PARTY_LICENSES.md.
• Microsoft Fluent Emoji Flat under the MIT License for the local sticker browser. The app loads the bundled Iconify JSON catalog only when the user opens Stickers and stores Microsoft, the source item, and the MIT license with each imported sticker. The retained license is in licenses/FLUENT_EMOJI.txt.

Video Editor models download from their configured upstream repositories only when the related tool starts, then remain in browser Cache Storage or OPFS until removed. The MOSS browser runtime and retained notices ship under frontend/static/moss-tts/; model weights are not bundled.

OpenPost does not include or import code, styles, utilities, or components from the commercial shadcn Designer package.
