Bindingper-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
Interfacerest, rsync, cli rest
Toolingbutler CLI (butler push / butler download / butler status) plus the Wharf HTTP API — GET https://api.itch.io/wharf/latest?target=user/game&channel_name=X returns the build manifest. butler does rsync-style block diffing so re-pushes are cheap.
Composes with30 GB per build x unlimited channels per project (channel name is arbitrary: windows, osx, bonus, dlc-1, shard-01...) x up to 20+ projects per free account. 1 project x 20 channels = 600 GB on one free account. Each build is independently addressable and downloadable.
ReliabilityPushing the same directory twice is a no-op, so versions accumulate as distinct builds rather than overwriting; butler auth uses an API key, and a project can be taken down by moderation (technical effect: URL 404s, data gone).
