verdict: storage/curseforge-author-file-hosting says qualifies-with-caveat, storage/curseforge-author-upload-api says fails-quota

Free tier	What IS verifiable is the observed size distribution: live file listings show modpacks at 89.1, 101.6 and 468.1 MB, and a single mod file at 66.7 MB. The one hard number surfaced is a media cap of 2 MB for images ('Why is it only 2MB??' - author complaint, still open, 'Future consideration'), and a forum report of a 350 MB mod upload being rejected without an external-URL option. unit MB; metered on unstated
Price	none stated
Per-object cap	not stated
Retention	retention: indefinite for approved files; 'Files updates in order to increase visibility is not allowed' and files must carry a changelog
Egress	Free and CDN'd via CloudFront in front of S3: edge.forgecdn.net and mediafilez.forgecdn.net return 'X-Cache: Miss from cloudfront' and 'Server: AmazonS3'. No billing. Hotlink-protected - a guessed object path returns 403 from S3 rather than bytes, so URLs must come from the API.
Identity	email (placeholder) not published
Limits	write-gated approved files source write-gated review gate', not as bulk storage source evidence points below 500 MB for mods (350 MB rejection reported, 468.1 MB modpack published, so the ceiling is game-dependent and enforced client-side per the August release notes: 'Added new client-side validation - preventing upload of large files on unsupported games'). retention: indefinite for approved files; 'Files updates in order to increase visibility is not allowed' and files must carry a changelog. request-rate: not published.
Binding	write-gated the write is a queue with a person or a rule in it, so the upload rate is set by somebody else
Interface	rest, sftp, rclone rest
Tooling	Official upload API with `X-API-TOKEN` and multipart `metadata` + `file` (third-party implementations exist, e.g. TeamDman/SuperFactoryManager and BreakBB/DisenchantBuddy shell out to it); `cfwidget` mirrors file metadata (id, filesize, uploaded_at) publicly. No SFTP, no rclone.
Composes with	Unlimited projects per author account, unlimited files per project, unlimited versions. The provider therefore polices project count and not only request rate.
Reliability	Reads are hotlink-gated (403 from S3 on constructed URLs) and the whole author surface is SSO-walled, so this is the least auditable of the game hosts. Moderation is active and rule-driven. Best treated as 'large-ish files with a review gate', not as bulk storage.
Notes	What IS verifiable is the observed size distribution: live file listings show modpacks at 89.1, 101.6 and 468.1 MB, and a single mod file at 66.7 MB. The one hard number surfaced is a media cap of 2 MB for images ('Why is it only 2MB??' - author complaint, still open, 'Future consideration'), and a forum report of a 350 MB mod upload being rejected without an external-URL option.

verdict: storage/curseforge-author-file-hosting says qualifies-with-caveat, storage/curseforge-author-upload-api says fails-quota

Free tier	No published per-file or total quota. Known caps: project media/gallery images limited to 2 MB (author complaint, Apr 2026); mod file upload limit not documented anywhere public — the biggest evidence gap in this dossier. unit MB; metered on unstated
Price	none stated
Per-object cap	not stated
Retention	not stated
Egress	Free, Cloudflare-fronted (edge.forgecdn.net / mediafilez.forgecdn.net), no auth on downloads.
Identity	email (placeholder) not published
Binding	none no constraint of a named kind was recorded; the verdict rests on the quota sentence rather than on a named limit
Interface	rest, rclone rest
Tooling	Documented Upload API: POST /api/projects/{projectId}/upload-file with multipart `metadata` + `file`, X-Api-Token header; also Maven for some project types. Third-party wrapper: github.com/itsmeow/curseforge-upload. No rclone.
Composes with	Unlimited projects per author account (no documented cap) x unknown per-file size. If the effective cap resembles Modrinth's 500 MiB, 1000 projects = ~500 GB.
Reliability	Manual moderation queue means automated bulk uploads get rejected or the author account locked; releases can be delisted retroactively.
Notes	No published per-file or total quota. Known caps: project media/gallery images limited to 2 MB (author complaint, Apr 2026); mod file upload limit not documented anywhere public — the biggest evidence gap in this dossier.
