Castport is a self-hosted podcast host: upload episodes, get an Apple/Spotify-valid RSS feed, clean public show pages, an embeddable player, and download stats — with your audio files never held hostage on someone else’s infrastructure. Transistor charges $19/mo ($228/yr, up to $684–$3,564 over three years) for what is, under the hood, an RSS feed and a folder of MP3s. Castport is $39 once. Built for the 99% of podcasters who don’t need network-scale dynamic ad insertion — just a bulletproof feed on their own domain.

• Unlimited shows, episodes, and downloads — no metering, ever
• Apple/Spotify-valid RSS: full itunes namespace, exact enclosure byte lengths, permanent GUIDs
• MP3/M4A uploads streamed to disk, markdown show notes with live preview
• Chapters editor emitting Podcasting 2.0 podcast:chapters
• Scheduled episodes — hidden from feed and pages until publish time, no cron needed
• Clean public show/episode pages with Apple/Spotify/RSS subscribe buttons + embeddable iframe player
• Download stats with daily-salted IP hashing — nothing personal stored
