Free tier	Free hosting with no stated numeric cap. Spotify's own episode-publishing doc: 'We don't have a file size limit'. The video doc repeats it: 'Spotify for Creators doesn't have a file size limit'. No episode count, storage or bandwidth cap is published anywhere — free, no paid tier, ad-revenue share is upside not a paywall. unit mixed; metered on stored-bytes
Price	none stated
Per-object cap	not stated
Retention	Second caveat: anchor.fm enclosures are 402/302 chains through anchor.fm/s/<id>/podcast/play/<n>/<urlencoded origin>, so the enclosure URL is a redirector with the object path embedded — permanent, but the served object is always the transcode.
Egress	Free and unmetered via Spotify's own CDN (d3ctxlq1ktw2nl.cloudfront.net). No egress meter, no per-download charge, no plan upgrade that changes it.
Identity	institution derived from the record's prose, not from an identity field, and no signup was executed: onnection is interrupted') — there is no resumable/chunked API, which is the real ceiling on file size in practice. media
Binding	none no constraint in the record binds at this scale; the record carries no limit of a kind the vocabulary names
Interface	rest rest
Tooling	No documented public upload API (the old Anchor API is gone; community projects like mahendranv/anchor-rss only scrape the public RSS). Upload is web/mobile UI only. Read side is a permanent RSS at https://anchor.fm/s/<showid>/podcast/rss — plain GET, no auth, serves the full back catalogue (one feed I pulled was 5.2 MB of XML).
Composes with	Unlimited shows per Spotify account (the UI has 'Add a new show' with no published cap) x unlimited episodes x no file-size limit. Also accepts video (MP4/MOV/MPG) on the same free tier, so the payload need not be audio at all.
Reliability	RE-ENCODES everything to 128 kbps stereo. Verified live: enclosure for an episode with itunes:duration 00:52:22 declared length=50272965; the staging object at d3ctxlq1ktw2nl.cloudfront.net/staging/2026-9-21/434650861-44100-2-6d67ddd17af0f.mp3 returns 206, Content-Range 0-1023/50272965, and its first 1 KB is a bare MPEG frame with no ID3 header at all. 50,272,965 x 8 / 3142 s = 128,003 bps — exactly 128 kbps CBR. The '-44100-2-' in the filename is the ingest normaliser's fingerprint (44.1 kHz, 2 channels). Your WAV or 320k MP3 does not survive. Second caveat: anchor.fm enclosures are 402/302 chains through anchor.fm/s/<id>/podcast/play/<n>/<urlencoded origin>, so the enclosure URL is a redirector with the object path embedded — permanent, but the served object is always the transcode.
