直达号 is presented on its official homepage as “personal profile storage” (个人资料存储).

It is positioned as a personal data storage service for users who want to keep personal information, documents, or materials in one place; it can be compared with a personal data repository or lightweight knowledge base. The current official site only clearly states its core capability: “personal profile storage”. It does not disclose collaboration, search, or other additional features.

The available materials do not state whether self-hosting is supported, nor do they provide deployment requirements, minimum resources, or dependencies. If you plan to use it in China, separately confirm support for WeChat login, sharing, notifications, object storage, SMS, CDN, and other domestic service providers.
