| Free tier | Unlimited total storage on the free 普通版: '无限制的总存储空间，分享免登录，不限制下载流量，不限速，不限制下载次数'. Per-file cap is the binding constraint, and it is tier-set in 个人中心 → 文件升级. unit unlimited; metered on stored-bytes |
|---|---|
| Price | none stated |
| Limits |
Per-file cap widely reported at 100 MB for free raised per-account via the 文件升级 setting; Share links are public by design. Registration requires 手机号 + SMS code. |
| Identity | institution (inferred, not read) not published |
| Egress | Explicitly unmetered: no download traffic limit, no speed limit, no download-count limit, and shares download without login. |
| Per-object cap | Per-file cap widely reported at 100 MB (100000000 bytes) |
| Retention | not stated |
| Interface | unknown wrapper-only |
| Tooling | No official API. Community wrappers exist (lanzou uploader scripts, lanzou-api style repos); the browser upload form is the only documented path. |
| Composes with | Registration needs a mainland phone number, so chaining is bounded by SIM supply, not by quota. |
| Reliability | Registration is SMS-gated on a Chinese mobile number, which is the hardest registration gate. No API means any large-scale use depends on an unofficial wrapper that breaks when the web form changes. |

| Free tier | Unlimited total storage on the free tier: '拥有无限制的总存储空间'. The per-file cap is on the per-object field unit unlimited; metered on stored-bytes |
|---|---|
| Price | none stated |
| Limits | |
| Binding | per-object-cap The total is genuinely unlimited and the egress is genuinely free, so nothing about capacity or traffic binds. 100 MB per object over a 10 TiB working set is 105,000 objects, which makes the file count the problem before the bytes. |
| Identity | country-phone the register form (pc.woozooo.com, terms on accounts.woozooo.com) asks for 手机号 plus an SMS code, then a username and password; it shows no email field and no country selector. A foreign-number path is unverified: behind a sign-up |
| Egress | Free and explicitly unmetered: '下载不限速度，不限流量，不限次数，免登录下载'. The free product is ad-funded and the FAQ states 我们对下载速度不做任何限制 free allowance: unlimited |
| Per-object cap | 100 MB per file on the free tier: '不限空间大小，不限下载速度，只是限制文件大小，最大不超过100M/个文件' (100000000 bytes) |
| Retention | unverified: the vendor home page as read states no share-link lifetime; account retention is not published |
| Interface | rest |
| Tooling | no official API. Reverse-engineered clients mount it: the OpenList Lanzou driver in account, cookie or link mode, and a mature unofficial Python wrapper, zaxtyson/LanZouCloud-API, which does login, list, upload, download, delete, move, folder operations and direct-link extraction, and whose README claims it works around both the file-type and the per-file size limits by splitting |
| Composes with | Unlimited total times 100 MB per object is the pure per-record-unlimited shape: 20 TiB is about 210,000 objects, all inside one free account's allowance. The gate is that registration is SMS-only on a mainland number |
| Reliability | Domains rotate constantly, across lanzou.com, lanzoue, lanzouj, lanzoux and lanzoul, and a share link that works on one suffix 404s on another, so a script must carry a domain list. The CDN host itself is geo-flaky. |
| Notes | The vendor's own page says unlimited and that is what is recorded, with the disagreement named. |
