Patreon private RSS for podcasters: how per-subscriber authenticated feeds work

Private podcast RSS is the technical core of most Patreon memberships for audio creators. This guide explains how the per-subscriber authenticated URL model works on Patreon, what happens to a patron's feed when they cancel, who actually owns the audio files, and how the four main private RSS platforms — Patreon native, Memberful, Supercast, and Castos — differ in ways the fee comparison tables usually miss.

What a private podcast RSS feed actually is

A standard public podcast RSS feed is a URL anyone can add to any podcast app. A private feed works on the same RSS protocol, but access is controlled by embedding a per-subscriber authentication token directly in the feed URL. There is no login prompt — the token IS the password, baked into the URL itself.

A patron's private feed URL might look like:

https://feeds.patreon.com/creatorslug/rss?auth=abc123xyz456

When the patron's podcast app polls that URL for new episodes, the server checks whether the token is valid and whether the corresponding subscription is still active. If both pass, the app receives the feed XML with the episode list and audio file links. If the subscription has lapsed or been cancelled, the server returns a 401 or an empty feed — and the patron's app shows no new episodes or removes the feed entirely.

The authentication model means the token itself is sensitive. If a patron shares their feed URL publicly — accidentally or intentionally — anyone with that URL can listen for as long as the token is valid. Most private feed platforms revoke tokens on cancellation, but the window between a patron sharing a URL and a creator noticing it is always open.

How Patreon's native private RSS works

Patreon generates a per-patron RSS URL for creators who enable the "patron-only podcast feed" option in their creator settings. Each patron who qualifies (based on tier) gets a unique URL delivered to them in their Patreon account page under "My Podcasts" or equivalent. They add that URL to their podcast app of choice — Pocket Casts, Overcast, Apple Podcasts, Spotify (limited support), or any standard RSS-capable client.

The mechanics Patreon controls:

The critical constraint: Patreon hosts the audio files. You upload episode audio to Patreon and they serve it from their CDN. The feed URLs, the episode media URLs, and the token authentication all run through Patreon's infrastructure. If you leave Patreon, you can download your MP3 files from your creator dashboard — but the per-subscriber URLs your patrons added to their apps go dead immediately. Every patron must manually re-add a new feed URL from wherever you migrate to. For a podcast with 500 patrons, that is 500 manual steps that most people will not complete without direct prompting, and even with outreach you will lose 15–25% of subscribers in the transition.

The November 2026 Apple Tax and private podcast RSS

The November 1, 2026 Apple Tax deadline is about subscription billing, not audio delivery. Apple's 30% IAP cut applies to in-app purchase transactions — the moment when a patron pays to subscribe. The RSS feed delivery itself (the MP3 file download) is not subject to Apple's cut regardless of which platform you use.

The fee impact for podcast creators specifically:

All four platforms — Patreon (web-only toggle), Memberful, Supercast, and Castos — use Stripe for subscription billing when patrons subscribe on the web. That means all four are structurally exempt from Apple's 30% IAP cut as long as patrons subscribe via a browser rather than the iOS app. The fee difference between them is the platform percentage on top of Stripe's baseline, not Apple's cut.

Where Patreon is uniquely vulnerable: if creators do not actively direct patrons to subscribe via the web, new iOS patrons who subscribe through the Patreon iOS app after November 1, 2026, will trigger Apple's IAP billing. The Patreon web-only billing guide covers how to set this up and how to communicate it to patrons. Memberful, Supercast, and Castos have no equivalent risk because they do not have their own iOS apps through which patrons subscribe — subscription always happens on the web.

Memberful: your audio, their billing infrastructure

Memberful takes a different architectural approach from Patreon. You bring your own podcast hosting — Transistor, Buzzsprout, Captivate, Anchor, or any RSS-generating host — and Memberful handles subscriber authentication on top of it. When a patron subscribes via Memberful, they receive a unique feed URL that runs through Memberful's authentication proxy. Their podcast app hits Memberful's servers, Memberful confirms the subscription is active, and the app then retrieves the episode audio from your existing host.

The meaningful advantage over Patreon native RSS: because the audio files live on your podcast host rather than Memberful's servers, you have full portability of the content. If you switch membership platforms, you are only migrating the billing and authentication layer — your episodes stay at the same host, with the same non-private feed URL for any free episodes. The private subscriber-URL problem (patrons must re-add a new feed) still exists when you leave Memberful, but your audio archive is portable without re-uploading anything.

Memberful's fee structure makes sense above approximately $807/mo gross — that is where Memberful's plan cost plus percentage beats Patreon Pro web-only (8%). Below that, Patreon web-only is cheaper. The Patreon vs Memberful deep-dive has the inflection math at all revenue bands.

Supercast: purpose-built private podcast infrastructure

Supercast is the only platform in this comparison that was built exclusively for private podcast delivery. It does not do general membership pages, communities, or email newsletters. It does one thing: generate authenticated per-subscriber RSS feeds and manage subscription billing for audio creators.

Supercast's dual-feed model is its most useful architectural detail. You maintain a public RSS feed (distributed to Apple Podcasts, Spotify, etc.) with the free episode catalog, and a separate private feed for subscriber-only episodes. Supercast manages the authentication for the private feed and can also deliver bonus subscriber-only episodes as additions to the public feed for subscribers — so a subscriber who adds the private feed URL sees both the public episodes and the bonus episodes in one feed, rather than needing two separate subscriptions in their app.

Like Patreon native RSS, Supercast hosts the audio on their CDN. The episode URLs embedded in the private feed XML point to Supercast's servers, not your own. If you leave Supercast, subscriber feed URLs break and you need to re-upload your back catalog to the next platform. The migration burden is comparable to leaving Patreon — higher than leaving Memberful, which preserves your audio at your existing host.

At $4,200/mo gross, Supercast's 5% fee equals $210/mo in platform fees plus the base plan cost plus Stripe's 2.9%. That lands Supercast slightly above Memberful's total cost at similar revenue, but Supercast's audio infrastructure is more polished for podcast-first operations — better subscriber-management tooling, explicit episode-level access control (subscriber-only vs public per episode), and native app compatibility with every major podcast client tested without workarounds.

Castos: hosting-integrated private feeds

Castos is a podcast hosting company that builds private feed management into the hosting platform itself, either as a standalone tool or via the Seriously Simple Podcasting WordPress plugin. Creators who already host their public podcast on Castos can activate private subscriber feeds without switching to a separate membership platform.

Castos's pricing model is the flattest in this comparison: a monthly hosting fee with no percentage cut on subscription revenue above the base. At $4,200/mo, that makes Castos the cheapest option on raw fee math — lower than Patreon web-only (8% = $336/mo), lower than Memberful's percentage, and lower than Supercast's 5%. The practical constraint: Castos is genuinely a podcast host that added subscription features, not a membership platform. Subscriber management, tier logic, and billing workflows are less mature than Memberful or Supercast. Creators who need multiple tiers, granular episode-level access control, or tight Discord role automation will need additional tooling.

For podcast creators whose entire product is audio — no Discord community, no patron posts, just the feed — Castos is worth serious consideration purely on fee savings. For creators where Discord community access is a core membership benefit, Castos requires a manual webhook setup via Zapier to replicate what Patreon and KeepTier handle natively.

Platform comparison: private RSS mechanics

The subscriber-URL migration problem

Every platform in this table uses per-subscriber authenticated URLs. That means every platform has the same migration problem: if you switch platforms, the URLs your subscribers added to their podcast apps become invalid. Getting subscribers to add a new feed URL requires active communication — a dedicated patron-only episode, an email to subscribers, a Patreon/membership post — and even with all of that, some percentage will not update the URL and simply stop receiving episodes without realising it.

Industry experience puts subscriber re-add rates at 70–85% with a proactive migration campaign and as low as 40–50% without one. That loss is structural — it exists regardless of which platform you move from or to. The only way to eliminate it entirely is to never switch platforms, or to accept the loss and run a tight migration. The how to leave Patreon guide has the 30-day playbook for minimising that drop.

Memberful partially mitigates this: because your audio lives at your podcast host, the public feed URL (for free episodes) does not change. Only the private subscriber feed URL breaks on migration. For creators with a mix of free and paid episodes, that means the public audience continues without disruption — only paying subscribers need to act.

Which platform to choose: a decision framework

The right platform depends on what your membership's primary value proposition is and how much you weight fee cost vs operational simplicity:

What Patreon's web-only toggle actually changes for RSS

If the only problem you want to solve is the November 2026 Apple Tax, Patreon's web-only billing mode is the lowest-friction option for podcast creators. It changes how new patrons subscribe (they must use a browser, not the iOS app) without changing the private RSS infrastructure. Existing patrons keep their current feed URLs. New patrons get their private feed URL the same way as before. No subscriber re-add campaign. No migration.

The trade-off: you stay on Patreon's 8% platform fee. At $4,200/mo, that is $336/mo forever, vs $99/mo on Castos or $0/mo platform fee on KeepTier. The web-only toggle buys you time to evaluate migration options without triggering the subscriber re-add problem in the middle of a November launch window.

For podcast creators who have the time to plan a migration, the long-term fee savings — $2,844/yr to $4,836/yr vs Patreon web-only at $4,200/mo — justify the migration effort. For creators whose membership is tightly integrated with a Discord community and Patreon's native Discord bot, Patreon web-only plus KeepTier as a parallel web-billing page is a way to capture new subscribers without the bot swap.
