verdict: storage/stoat-autumn-file-service says fails-quota, storage/stoat-official-instance says qualifies-with-caveat

Free tier	20,000,000 bytes (20 MB) per attachment as the server-enforced default, no paid tier to raise it, and no documented total storage cap. unit MB; metered on stored-bytes
Price	none stated
Per-object cap	20 MB per file (20000000 bytes)
Retention	\| Critically different from Discord: attachment URLs are UNSIGNED and permanent
Egress	Free and unmetered from cdn.stoatusercontent.com (Cloudflare). The CDN responses I fetched carried `Cache-Control: public, max-age=2073600` — 24 days of edge caching — which is good for the 500 GB/day serving workload.
Identity	email (placeholder) not published
Limits	per-object-cap 20 MB per file source 20 MB per file; 5 attachments per message; body_limit_size 20,000,000 bytes globally. Live limits object also gives: emojis 500 KB, icons 2.5 MB, banners/backgrounds 6 MB, avatars 4 MB — those are separate, smaller buckets.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest rest
Tooling	Autumn file service: `POST {autumn}/attachments` with multipart `file` and `X-Bot-Token`/`X-Session-Token`. Documented at stoatchat/stoatchat `docs/docs/developers/api/uploading-files.md`. Bots are first-class; 5 bots per account.
Composes with	100 servers per account x 200 channels per server (from the live `/` limits object) = 20,000 channels, each with unlimited messages. Servers are capped at 100 for existing accounts / 50 for new ones.
Reliability	Critically different from Discord: attachment URLs are UNSIGNED and permanent. The platform renamed Revolt->Stoat in Oct 2025 and moved the CDN (autumn.revolt.chat -> cdn.revoltusercontent.com) in May 2025 with 301s still in place; old IDs from the pre-refactor Autumn do 404.
Notes	20,000,000 bytes (20 MB) per attachment as the server-enforced default, no paid tier to raise it, and no documented total storage cap.
Evidence rung	reported One page read moves it to documented.
Checked	2026-10-21 (inherited); stale on 2026-11-04
Parsed numbers	`$.limits[0].value` limit:per-object-cap 20.0 MB

verdict: storage/stoat-autumn-file-service says fails-quota, storage/stoat-official-instance says qualifies-with-caveat

Free tier	20 MB per file, no subscription: 'Custom emojis, a 20MB file upload limit and a server-specific profile picture with no subscription required.' No published total-storage cap and no paid tier that raises the file size. unit MB; metered on stored-bytes
Price	none stated
Per-object cap	20 MB per file (20000000 bytes)
Retention	not stated
Egress	Free and — importantly — UNSIGNED. Autumn 301s to cdn.stoatusercontent.com and the object URL is a bare path with no expiry parameters, unlike Discord. So a stored URL stays valid and is trivially Cloudflare-cacheable.
Identity	email (placeholder) not published
Limits	per-object-cap 20 MB per file source 20 MB per file is fixed and low; there is no path to a bigger unit. Upload limits are server-configurable only on SELF-hosted instances ('Upload limits are controlled via the Autumn config'), so on the public instance you are stuck at 20 MB.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest rest
Tooling	Genuinely open: 'Our public API is so powerful that we use it ourselves for the official apps', API root answers live (GET https://api.revolt.chat/ -> {"stoat":"0.16.2","revolt":"0.16.2", features...}). Backend is open source (revoltchat/autumn, stoatchat/*). Self-hostable, which is both the appeal and the caveat.
Composes with	Unlimited servers x unlimited channels with a 20 MB cap, so 1 TB needs ~52,000 uploads. With no signed URLs, the reads are the easy part; the writes are the bottleneck.
Reliability	Smaller operator, recent rebrand to Stoat, and the public instance runs human-verification step on signup. Data longevity is a real question for a 20 TiB cold archive; treat as experimental.
Notes	20 MB per file, no subscription: 'Custom emojis, a 20MB file upload limit and a server-specific profile picture with no subscription required.' No published total-storage cap and no paid tier that raises the file size.
Evidence rung	reported One page read moves it to documented.
