koishijs/koishi is a framework that attaches multiple chat platforms such as QQ, Telegram, and Discord as plugins and manages them as a single chatbot. The latest release confirmed in this repository is 4.18.11, and the source is the GitHub repository page.
The heart of this framework is a structure that bundles multiple chat services into one program through platform adapters and event handling. The README states that it provides a console and an online plugin market, and supports major chat platforms such as QQ, Telegram, and Discord, along with multi-account support (handling several accounts on one platform together) and data linkage between platforms. It is developed in TypeScript and released under the MIT license. Unit tests for core features and module hot reload (the feature of re-reading and loading modules) during plugin development are supported. The repository was created on December 3, 2019 and has 6268 stars.
That said, the evidence stops there. Because the release notes and change list for 4.18.11 are not provided, it is not possible to confirm what changed in this version. There are also no performance measurements or adoption case figures in this material. In the provided record, only the Momentum item has a score of 4.0, while the Freshness, Technology, and Quality items are empty. The structure that unifies multiple messengers in one framework is confirmed, but it is difficult to judge from the documentation alone the scale and stability that structure has reached. For now, it is better to keep this as a candidate for reviewing chat platform integration structures.
