# Third-Party Notices ## Project origins and acknowledgments OpenPI originated from [davis7dotsh/my-pi-setup](https://github.com/davis7dotsh/my-pi-setup) and is maintained as an independent distribution. Thanks to the original author for the starting point. Web workbench contributions include: - [@testikun](https://github.com/testikun): Web runtime source information ([#398](https://github.com/openpi-dev/openpi/pull/398)) and Pi project trust diagnostics ([#392](https://github.com/openpi-dev/openpi/pull/392)). - [QuinnWan (@somewan820)](https://github.com/somewan820): UI restoration baseline and clipboard fallback ([#352](https://github.com/openpi-dev/openpi/pull/352)), carried forward through the React migration ([#384](https://github.com/openpi-dev/openpi/pull/384)). - [@seekskyworld](https://github.com/seekskyworld): request timeout protection ([#377](https://github.com/openpi-dev/openpi/pull/377)) and native cancellation proposals ([#358](https://github.com/openpi-dev/openpi/pull/358)), whose goals were integrated with the existing React transport and cancellation implementation, including additional regression coverage. The optional top-level Session communication package is [pi-intercom](https://github.com/nicobailon/pi-intercom). ## OAuth model providers `extensions/ai-providers/` adapts protocol and OAuth details from [`oh-my-pi`](https://github.com/can1357/oh-my-pi) (Antigravity Cloud Code Assist and Cursor AgentService). The upstream project is distributed under the MIT License. Its copyright notice states `Copyright (c) 2025 Mario Zechner`, `Copyright (c) 2025-2026 Can Bölük`, and `Copyright (c) 2026 Stencil Labs, Inc.`; the complete license text is included at [`extensions/ai-providers/LICENSE.upstream`](extensions/ai-providers/LICENSE.upstream). The local Antigravity message conversion is adapted from the same project's pi-ai 0.84.1 Google conversion implementation so the installed extension does not depend on a non-public Pi runtime module. Cursor support in this package is chat-only: it does not copy or execute Cursor-native coding tools. ## Sessions extension `extensions/sessions/` is adapted from [`jayshah5696/pi-agent-extensions`](https://github.com/jayshah5696/pi-agent-extensions), version 0.5.2. The upstream project is distributed under the MIT License. Its notice states `Copyright (c) 2026`; the complete license text is included at [`extensions/sessions/LICENSE.upstream`](extensions/sessions/LICENSE.upstream). OpenPI is distributed under the MIT License; see [`LICENSE`](LICENSE). Portions identified in this notice retain their original copyright notices and license terms. The project-wide MIT license does not replace or remove those notices. ## Web production bundle `web/dist/app.js` and `web/dist/styles.css` contain code from the packages listed below. This inventory was taken from the Vite production module graph; build-only packages are not included. ### MIT-licensed packages Copyright (c) 2026 Meta Platforms, Inc.: - `@astryxdesign/core@0.5.2` - `@astryxdesign/theme-neutral@0.5.2` Copyright (c) Meta Platforms, Inc. and affiliates: - `@stylexjs/stylex@0.19.0` - `react@19.2.8` - `react-dom@19.2.8` - `scheduler@0.27.0` - `use-sync-external-store@1.6.0` Copyright (c) 2023 FormatJS: - `@formatjs/fast-memoize@3.1.7` - `@formatjs/icu-messageformat-parser@3.5.17` - `@formatjs/icu-skeleton-parser@2.1.11` Copyright (c) 2011-present i18next: - `i18next@26.4.1` Copyright (c) 2015-present i18next: - `react-i18next@17.0.13` Copyright (c) 2026 Espen Hovlandsdal : - `eventsource-parser@4.1.0` Copyright (c) Espen Hovlandsdal: - `react-markdown@10.1.0` Copyright (c) 2019 Paul Henschel: - `zustand@5.0.15` Copyright (c) Sindre Sorhus (): - `escape-string-regexp@5.0.0` - `is-plain-obj@4.1.0` Copyright (c) 2012 TJ Holowaychuk : - `inline-style-parser@0.2.7` Copyright (c) 2014 Stefan Thomas: - `extend@3.0.2` Copyright (c) 2017 Menglin "Mark" Xu : - `style-to-object@1.0.14` Copyright (c) 2020 Menglin "Mark" Xu : - `style-to-js@1.1.21` Copyright (c) 2014 Titus Wormer : - `remark-parse@11.0.0` Copyright (c) 2015 Titus Wormer : - `bail@2.0.2`, `ccount@2.0.1`, `mdast-util-to-string@4.0.0` - `unified@11.0.5`, `unist-util-is@6.0.1`, `unist-util-position@5.0.0` - `unist-util-visit@5.1.0`, `vfile@6.0.3` Copyright (c) 2015 Titus Wormer : - `longest-streak@3.1.0`, `trim-lines@3.0.1` Copyright (c) 2016 Titus Wormer : - `comma-separated-tokens@2.0.3`, `hast-util-whitespace@3.0.0` - `mdast-util-to-hast@13.2.1`, `rehype-sanitize@6.0.0` - `space-separated-tokens@2.0.2`, `trough@2.2.0` - `unist-util-stringify-position@4.0.0`, `unist-util-visit-parents@6.0.2` Copyright (c) 2017 Titus Wormer : - `mdast-util-newline-to-break@2.0.0`, `remark-breaks@4.0.0` Copyright (c) 2020 Titus Wormer : - `estree-util-is-identifier-name@3.0.0` - `mdast-util-gfm-autolink-literal@2.0.1` - `mdast-util-gfm-strikethrough@2.0.0`, `mdast-util-gfm-table@2.0.0` - `mdast-util-gfm-task-list-item@2.0.0`, `micromark-extension-gfm@3.0.0` - `micromark-extension-gfm-autolink-literal@2.1.0` - `micromark-extension-gfm-strikethrough@2.1.0` - `micromark-extension-gfm-task-list-item@2.1.0` Copyright (c) 2021 Titus Wormer : - `micromark-extension-gfm-footnote@2.1.0` Copyright (c) 2023 Titus Wormer : - `devlop@1.1.0` Copyright (c) Titus Wormer : - `decode-named-character-reference@1.3.0`, `hast-util-sanitize@5.0.2` - `hast-util-to-jsx-runtime@2.3.6`, `markdown-table@3.0.4` - `mdast-util-find-and-replace@3.0.2`, `mdast-util-from-markdown@2.0.3` - `mdast-util-gfm@3.1.0`, `mdast-util-gfm-footnote@2.1.0` - `mdast-util-to-markdown@2.1.2`, `micromark@4.0.2` - `micromark-core-commonmark@2.0.3`, `micromark-extension-gfm-table@2.1.1` - `micromark-factory-destination@2.0.1`, `micromark-factory-label@2.0.1` - `micromark-factory-space@2.0.1`, `micromark-factory-title@2.0.1` - `micromark-factory-whitespace@2.0.1`, `micromark-util-character@2.1.1` - `micromark-util-chunked@2.0.1`, `micromark-util-classify-character@2.0.1` - `micromark-util-combine-extensions@2.0.1` - `micromark-util-decode-numeric-character-reference@2.0.2` - `micromark-util-decode-string@2.0.1`, `micromark-util-html-tag-name@2.0.1` - `micromark-util-normalize-identifier@2.0.1` - `micromark-util-resolve-all@2.0.1`, `micromark-util-sanitize-uri@2.0.1` - `micromark-util-subtokenize@2.1.0`, `remark-gfm@4.0.1` - `remark-rehype@11.1.2`, `vfile-message@4.0.3` Copyright (c) Titus Wormer: - `html-url-attributes@3.0.1` Copyright (c) Titus Wormer : - `property-information@7.2.0` `mdast-util-phrasing@4.1.0` retains both of its notices: - Copyright (c) 2017 Titus Wormer - Copyright (c) 2017 Victor Felder The MIT terms for the packages above are: > Permission is hereby granted, free of charge, to any person obtaining a copy > of this software and associated documentation files (the "Software"), to deal > in the Software without restriction, including without limitation the rights > to use, copy, modify, merge, publish, distribute, sublicense, and/or sell > copies of the Software, and to permit persons to whom the Software is > furnished to do so, subject to the following conditions: > > The above copyright notice and this permission notice shall be included in > all copies or substantial portions of the Software. > > THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR > IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, > FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
