Open source & third-party software
Terakhir diperbarui: 12 September 2026
This page documents how SAI IDE (Sekretarisku AI / Myryda) is built, which open-source projects it uses, and the licenses and trademarks that apply. It exists so users, partners, and rights holders can see that SAI is an independent product based on licensed open-source software — not an official Eclipse, Microsoft, or Visual Studio Code product.
Publisher: PT. Rytech Digital Industry (Myryda). Product site: sekretarisku.com/sai.
1. Independent product
SAI IDE is a commercial desktop coding environment with a built-in AI agent. PT. Rytech Digital Industry develops, brands, distributes, and supports SAI. SAI is not affiliated with, endorsed by, or sponsored by the Eclipse Foundation, Microsoft, OpenJS Foundation, or the Electron project.
SAI does not use the product names, logos, or trade dress of Visual Studio Code, VS Code, Eclipse Theia IDE, or Electron as its own product identity. The Windows application is installed as SAISetup.exe and runs as SAI.
2. How SAI is built
SAI is assembled from well-known open-source building blocks, plus SAI-specific extensions and cloud services:
- Eclipse Theia — the IDE framework (workbench, workspace, plugins, AI chat shell).
- Theia IDE (formerly Theia Blueprint) — the desktop application template SAI is derived from.
- Electron — the Windows desktop runtime (Chromium + Node.js).
- Monaco Editor — the code editor component used through Theia.
- VS Code extension compatibility — Theia’s plugin layer can load many Open VSX / VS Code-compatible extensions. That is an Eclipse Theia feature, not a redistribution of the Visual Studio Code product.
- SAI extensions and services — authentication, credit metering, model routing, and the coding agent are SAI’s own work and cloud APIs.
3. Eclipse Theia — Eclipse Public License 2.0
The @theia/* packages shipped in SAI come from Eclipse Theia. Eclipse Theia is licensed under the Eclipse Public License 2.0 (EPL-2.0), with a secondary GPL-2.0 + Classpath exception as published by the project.
SAI currently uses Eclipse Theia 1.75.0-next.43. Upstream source:
- https://github.com/eclipse-theia/theia
- License: LICENSE (EPL-2.0)
EPL-2.0 lets us combine Eclipse Theia with SAI’s own modules in a commercial product, provided we keep copyright notices, include the license with distributions, and make the corresponding source of EPL-covered code — including our modifications to those packages — available under EPL-2.0. SAI-only modules (agent bridge, billing, authentication) are separate files and remain SAI’s own software.
Modifications to Eclipse Theia packages
SAI applies limited patches to these Eclipse Theia packages: @theia/core, @theia/remote, @theia/ai-chat-ui, and @theia/terminal. Those modifications are distributed under EPL-2.0. Corresponding source is available on request at myryda.digital@gmail.com (subject: “EPL corresponding source — SAI”). Unmodified Theia source remains at the upstream repository above.
4. Theia IDE template — MIT
The desktop shell SAI started from is Theia IDE (previously Theia Blueprint), licensed under the MIT License:
Copyright (c) 2020 Eclipse Theia IDE Authors / Eclipse Theia Blueprint Authors
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…
The full MIT text is bundled with the Windows installer and is also published at theia-ide/LICENSE. The MIT copyright and permission notice are retained as required.
5. Other major components
SAI also redistributes or dynamically uses the following projects. Each remains the property of its respective authors and is used under its own license. This list covers the main runtime pieces; the installer and application files include additional dependency notices.
| Component | Role in SAI | License | Project |
|---|---|---|---|
| Eclipse Theia | IDE framework | EPL-2.0 | eclipse-theia/theia |
| Theia IDE | Desktop app template | MIT | eclipse-theia/theia-ide |
| Electron | Windows desktop runtime | MIT | electron/electron |
| Chromium | Bundled with Electron | BSD-3-Clause and others | chromium.org |
| Node.js | Bundled with Electron | MIT | nodejs.org |
| Monaco Editor | Code editor (via Theia) | MIT | microsoft/monaco-editor |
| VS Code built-in extensions | Language basics, shipped via Theia | MIT (and notices in each extension) | eclipse-theia/vscode-builtin-extensions |
| React / React DOM | Theia UI runtime | MIT | facebook/react |
| Open VSX | Optional extension registry | EPL-2.0 | open-vsx.org |
Other npm packages bundled with the application (for example Inversify, TypeScript tooling at build time, and installer helpers) are used under MIT, ISC, Apache-2.0, BSD, or similarly permissive licenses as declared by those packages. Eclipse Dash license checks are part of the Theia IDE build.
6. What SAI does not claim
- SAI is not Visual Studio Code, VS Code, or a Microsoft product.
- SAI is not the official Eclipse Theia IDE binary published by the Eclipse Foundation.
- Compatibility with many VS Code extensions comes from Eclipse Theia’s open plugin API, not from copying the Visual Studio Code product.
- Microsoft, Visual Studio, Visual Studio Code, VS Code, Eclipse, Theia, Electron, Node.js, and related names are trademarks of their respective owners. See section 8.
7. Source availability
For software licensed under EPL-2.0 that SAI redistributes:
- Unmodified Eclipse Theia source: github.com/eclipse-theia/theia (the version listed in section 3).
- SAI modifications to EPL-covered Theia packages: available under EPL-2.0 on written request to myryda.digital@gmail.com.
- Theia IDE (MIT) upstream: github.com/eclipse-theia/theia-ide.
License texts also ship with the Windows installer. This website notice does not replace those files.
8. Trademarks
This documentation uses third-party names only to identify the software SAI is based on.
- Eclipse and Theia are trademarks of Eclipse Foundation AISBL. The first reference on this page is to Eclipse Theia. SAI is not an Eclipse Foundation project.
- Microsoft, Visual Studio, Visual Studio Code, and VS Code are trademarks of Microsoft Corporation. SAI is not affiliated with Microsoft.
- Electron is a trademark of OpenJS Foundation. Chromium is a trademark of Google LLC. Node.js is a trademark of the OpenJS Foundation.
Use of those names on this page is nominative: it describes the origin of components. It is not a grant of trademark rights, and it does not mean SAI is an official build of those projects. SAI does not use Eclipse or Microsoft logos in the product name, installer, or marketing as if SAI were those products.
9. Proprietary SAI software
Accounts, billing, credit metering, model routing, and the SAI coding-agent integration are provided by PT. Rytech Digital Industry. Those services and SAI-specific extensions are not Eclipse Theia and are not licensed under EPL-2.0 unless a specific file says otherwise.
