## mastodonapp.uk / mstdn.social / mastodon.social and the stock-Mastodon mass — 100 MiB per object, unlimited per account

- url https://mastodonapp.uk
- free tier: Per-account UNLIMITED. Per-file: 103809024 bytes = 99 MiB (video), 16 MiB image on almost every stock instance. mastodonapp.uk raises the IMAGE cap to 99 MiB too, which is the unusual bit. | unit: unlimited | metered on: unstated | read on: 2026-10-21 | source: [1]

- retention: not stated | source: [1] | note: not stated
- egress: Free. Media is offloaded to plain S3-compatible buckets behind the instance domain — verified on two live instances: mastodon.world serves from `s3.eu-central-2.wasabisys.com/mastodonworld/...` (Wasabi), mstdn.jp serves from `img.mstdn.jp/media_attachments/files/...`. | metered: no

- interface: rest, cli
- limits:
  - per-object-cap (binding): Per-file: 103809024 bytes = 99 MiB [1]
- limits note: mastodonapp.uk: image_size_limit and video_size_limit both 103809024 bytes (99 MiB), 4 media attachments per status; per-account unlimited and the API call rates are unverified on this host
- interface detail: rest
- tooling: Mastodon REST API v1; `toot` CLI; Mastodon.py; Mastodon-API clients in every language.
- composes with: THE quantity finding. Stock Mastodon has no per-account media quota — only a per-file validator. So a Mastodon account is a per-object-capped, per-account-unlimited store whose only real ceiling is (a) 30 uploads/30 min and (b) the operator's disk. There are thousands of open-registration instances. 1,000 instances x 99 MiB/object x 1,440 uploads/day is not the right sum; the right sum is 'each account is bounded by rate, not bytes', which makes the fediverse a permanent, free, CDN-fronted write target of effectively instance-disk size.
- reliability: Registration state varies per instance and flips often — mastodon.social, mstdn.social, mstdn.jp, mastodon.world, mastodon.gamedev.place all reported registrations=true at probe time; mas.to, fosstodon.org, chaos.social, toot.community, mastodon.online reported false. Re-probe before relying on any one.
- notes: the same as the free tier
- evidence note: documented: the image and video size limits and the attachments per status are quoted from https://mastodonapp.uk/api/v2/instance; the sign-up steps from https://mastodonapp.uk/auth/sign_up; the image size limit of a stock instance from https://mastodon.social/api/v2/instance; the media upload rate limit from https://docs.joinmastodon.org/api/rate-limits/ (read 2026-11-03)

  - dead_end.failure_class: quota
  - dead_end.why: Per-account UNLIMITED. Per-file: 103809024 bytes = 99 MiB (video), 16 MiB image on almost every stock instance. mastodonapp.uk raises the IMAGE cap to 99 MiB too, which is the unusual bit.
