Where Castport wins
Castport hosts the podcast without the meter: unlimited shows and episodes, an Apple/Spotify-valid RSS feed, public pages, an embeddable player, chapters and download stats — self-hosted for $99 once. A weekly show stops paying $144/yr just to keep its feed alive.
- Price, permanently. $99 once versus from $12/mo for as long as you use it. There is no renewal, no seat count and no tier gate.
- Unlimited shows & episodes. Each show gets its own artwork, iTunes category, language, explicit flag and custom feed slug. No per-show pricing tiers.
- Apple/Spotify-valid RSS. RSS 2.0 with the full itunes namespace, exact enclosure byte lengths, permanent GUIDs and valid pubDates — the details that actually get feeds rejected, done right.
The math
Buzzsprout lists from $12/mo. Castport is $99, paid once:
- After 1 year: Castport has cost you $99 total — Buzzsprout has cost ~$144.
- After 3 years: Castport is still $99 — the subscription is at ~$432.
- After 5 years: Castport is still $99 — the subscription is at ~$720.
Common questions
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/castport-mvp, always. $99 buys the packaged installer, guided deploy and lifetime updates.
Will Apple and Spotify actually accept the feed?
That's the part we sweated: exact enclosure byte counts (not estimates), permanent GUIDs, real probed audio durations, and proper HTTP Range support on audio — the exact details that get naive feeds rejected. Set BASE_URL to your real domain first; localhost feeds are rejected.
Who pays for the bandwidth?
You do — that's the honest trade-off of self-hosting. A $5 VPS comfortably serves a typical indie show; a genuinely huge audience is where Transistor's managed CDN infrastructure earns its monthly fee.
What about listener privacy?
Download stats hash IPs with a rotating daily salt, so you get unique-downloads-per-day trends without ever storing anything personal — and the data sits in your SQLite file, not a third party's dashboard.
