Attribution and licensing for open-source software used in Botverse services.
Botverse uses a number of open-source software components. Where licence terms require attribution or notice, those notices appear below. None of the LGPL or GPL components listed here are distributed to you as an API caller — they run server-side inside Botverse infrastructure.
This service uses code of FFmpeg licensed under the LGPLv2.1.
Source code is available at ffmpeg.org/download.html. FFmpeg is invoked as a separate binary process; Botverse does not modify or redistribute FFmpeg source code or binaries.
FFmpeg is a leading multimedia processing framework. Botverse uses it for video transcoding, audio extraction, and format conversion. SPDX: LGPL-2.1-or-later
License: Mozilla Public License 2.0 (core) / GNU LGPL v3 (some components) | https://www.libreoffice.org/about-us/licenses/
Used in headless mode for document format conversion (Markdown/HTML to DOCX, DOCX to PDF). LibreOffice is invoked as a separate process; Botverse does not modify or distribute LibreOffice. The Document Foundation trademark policy applies: Botverse does not use the LibreOffice name or logo as a product identifier.
License: GNU General Public License v2 or later | https://github.com/jgm/pandoc/blob/main/COPYRIGHT
Used for Markdown-to-document conversion. Pandoc is invoked as a separate process (not linked into Botverse server code). Server-side use under the GPL does not impose copyleft obligations on Botverse's own codebase or on callers of the Botverse API.
License: BSD 3-Clause Licence (and component-specific licences listed in Chromium's LICENSE file) | https://chromium.googlesource.com/chromium/src/+/main/LICENSE
Used in headless mode for HTML-to-PDF rendering. Chromium's BSD licence permits commercial server-side use with copyright notice retention. No user-facing attribution is required.
License: GNU Lesser General Public License v3 or later | https://github.com/strukturag/libheif/blob/master/COPYING
Used for HEIC/HEIF image decoding and conversion. Provided by Struktur AG. libheif is used unmodified as a shared library dependency. LGPL server-side use does not require source disclosure of Botverse's own code.
License: GNU Lesser General Public License v2.1 or later | https://github.com/libvips/libvips/blob/master/COPYING
Image processing library underlying the Sharp npm package. Used for image resizing and format conversion.
License: Apache License 2.0 | https://github.com/lovell/sharp/blob/main/LICENSE
Node.js image processing library. Used for image operations in Botverse Convert. Apache 2.0 permits unrestricted commercial use.
H.264 / AVC. H.264 video encoding is subject to patent rights administered by Via Licensing Alliance LLC (Via-LA). Botverse maintains an H.264 patent licence for encoding operations performed on this platform. This licence does not extend to end users or callers of the Botverse API for their own independent encoding operations.
H.265 / HEVC. Botverse does not currently offer H.265/HEVC video encoding. HEIC image decoding (used in image conversion) may implicate HEVC codec patents. Botverse endeavours to maintain appropriate licences for HEIC conversion operations. The open-source nature of codec libraries does not grant any patent licence. See the Terms of Service, Section 10, for the full patent notice.
AV1. AV1 is a royalty-free video codec developed by the Alliance for Open Media. All AOMedia members have committed to royalty-free licensing for AV1 implementations. Botverse recommends AV1 for workflows where long-term cost predictability and patent clarity are priorities.
