| Free tier | Quota is set by each game's developer as 'Byte quota per user' and 'Number of files allowed per user', 'enforced on each Cloud-enabled game, on a per-user-per-game basis'. No Valve-imposed total. Community-observed ceilings: 93 GB per game, ~10,000 files. Defaults are frequently tiny (a few MB to 1 GB). unit objects; metered on unstated |
|---|---|
| Price | none stated |
| Limits |
per-object-cap: 100 MB per FileWrite call (256 MB 'may result in a non-optimal storage endpoint'); per-object-cap: ~10,000 files per cloud save; the game must be launchable/owned for the user, and impersonating it blocks normal play during sync. Retention: indefinite — no expiry documented, but a developer can change quota or delist and the data can be evicted. |
| Identity | email (placeholder) not published |
| Egress | Unmetered and anonymous on the download path via the Steam client / Steamworks SDK. No published per-GB charge. |
| Per-object cap | 100 MB per File (100000000 bytes) |
| Retention | per-object-cap: 100 MB per FileWrite call (256 MB 'may result in a non-optimal storage endpoint'); per-object-cap: ~10,000 files per cloud save; the game must be launchable/owned for the user, and impersonating it blocks normal play during sync. Retention: indefinite — no expiry documented, but a developer can change quota or delist and the data can be evicted. |

| Tooling | Steamworks SDK ISteamRemoteStorage (FileWrite, FileWriteStreamWriteChunk, FileReadAsync). Working wrapper exists: github.com/Fldicoahkiin/SteamCloudFileManager — 237 stars, Rust, Windows/macOS/Linux, '支持任意文件的上传、下载与删除' (arbitrary file upload/download/delete against any owned game's cloud). Design writeup: krutonium.ca/posts/using-steam-as-cloud-storage/. |
| Composes with | One Steam account x every owned Cloud-enabled game with a large quota. At 93 GB/game, 12 games = ~1.1 TB; 100 games = ~9 TB. Multiply again by accounts. The lever is picking titles whose developers set 93 GB, not buying storage. |
| Reliability | Entirely undocumented by Valve; a developer lowering their quota can strand data, and files are re-downloaded into the local save folder on game launch. No public bans recorded. |

| Free tier | Per-item size is set by the game developer, not by Valve, and some games are explicitly unlimited — Arma 3: 'Arma 3 Workshop now support items of unlimited size.' Others are tiny: House Flipper raised its cap from 12 MB to 20 MB in a patch. So the quota is per-app, and the number of published items per account is not documented as capped. unit unlimited; metered on unstated |

Requires ownership of the game and a Steam client to upload — there is no headless upload path, which is the practical blocker. Per-item caps range from 20 MB to unlimited depending on app; preview images go through a separate Steam Cloud quota. |
| Identity | anonymous (inferred, not read) not published |
| Egress | Free and CDN-served by Valve's content network — same infrastructure as game downloads, genuinely unmetered. |
| Per-object cap | not stated |
| Retention | not stated |
| Interface | rest rest |
| Tooling | ISteamUGC (CreateItem + SetItemContent + SubmitItemUpdate) via the Steamworks SDK, so uploads need a Steam client with the game installed. Downloads are scriptable anonymously: steamcmd +login anonymous +workshop_download_item <appid> <publishedfileid>. Third-party downloaders (polocaz/ws-downloader, workshopfetch.com) exist for the read path. |
| Composes with | One Steam account x every Workshop-enabled game it owns x unlimited items per game. This is the multiplier: 'unlimited items per published file ID' inside an app whose developer set no cap. |
| Reliability | Very durable — Workshop items have survived a decade, links do not expire, and downloads are anonymous. Enforcement risk is real but technical: items can be delisted by the app's developer. |
