What is aki-bangumi-vault?

Bangumi Vault is a local-first backup tool for Bangumi, a Chinese website where users track anime, manga, books, games, and other media they have watched, read, or played. The tool is an independent third-party project with no official connection to Bangumi. The README is written in Chinese. The application lets you sync your Bangumi collection to your own computer, store cover images locally, and export your data in multiple formats. It is designed so that your collection data is primarily stored on your own device rather than depending entirely on the Bangumi website. There are two versions of the tool. The desktop version is an Electron application, meaning it runs as a standalone window on your computer without needing to open a browser. For Windows users, a pre-built installer is available from the GitHub Releases page. The desktop version saves your collection data to a local folder called "library" (resource folder in Chinese), which contains a JSON file with your collection, a folder for cached cover images, a backups folder, and a log folder. The online version is a plain web page hosted at a Netlify address that requires no installation but stores data in your browser's local storage, which means it could be lost if you clear browser data. The README recommends exporting a backup regularly when using the online version. Export options include JSON, CSV, Excel, Word, an offline HTML page, and a full ZIP archive. The app can also filter your collection by tags, distinguishing between your personal tags and public tags that are shared on the Bangumi platform. For developers who want to modify or build from source, the project uses Node.js and npm, and can be packaged into a Windows installer with a single npm command.
