Self-Hosted Podcast Hosting & Sync

Two unrelated problems share this page: publishing a podcast you make (RSS + audio hosting + analytics) and personal listening sync (subscriptions + episode progress across devices). Both are well-served by self-hosting in 2026. For audiobooks see Self-Hosted Photos & Media (Audiobookshelf).

Podcast publishing (host the show)

• ★ Castopod — full podcast publishing platform; ActivityPub-federated; podcast 2.0 namespace (chapters, transcripts, value-for-value, funding); analytics; multi-podcast. The default for "I publish a podcast and want to own it."
  • https://code.castopod.org/adaures/castopod
• podlove publisher — WordPress plugin; mature; podcast 2.0 features; works inside an existing WP site.
  • https://github.com/podlove/podlove-publisher
• Podcast Generator — tiny PHP; static-feeling; no DB-heavy install needed.
  • https://github.com/PodcastGenerator/PodcastGenerator
• Static-site + RSS — Hugo / Eleventy with a podcast-feed plugin works great if you don't need analytics. Host MP3s on R2 / S3.

Personal listening sync (subscriptions + progress)

• ★ PinePods — Rust + Python; modern UI; multi-user; subscribes via gPodder API; cross-device progress sync. Rising fast in 2026.
  • https://github.com/madeofpendletonwool/PinePods
• ★ Audiobookshelf — primarily for audiobooks but has a fully-featured podcast section: subscribe to feeds, download episodes, multi-user progress sync, mobile apps. The default if you already run it for audiobooks.
  • https://github.com/advplyr/audiobookshelf
• gPodder Sync (mygpo) — protocol + reference server for syncing podcast subscriptions / episode progress across clients (AntennaPod, Kasts, RePod, etc.).
  • https://github.com/gpodder/mygpo
• OpenPodcast / Funkwhale — alternative federated approach via Funkwhale.
• Nextcloud GPodderSync app — sync state via your Nextcloud instance; pairs with AntennaPod's Nextcloud sync feature.

Download / mirror tools

• ★ Podgrab — auto-download new episodes from any feed into a directory; pairs with Plex / Jellyfin / a phone for offline listening.
  • https://github.com/akhilrex/podgrab
• podsync — turn YouTube / Vimeo channels into podcast RSS feeds; great for "make this video channel a podcast in my player."
  • https://github.com/mxpv/podsync
• gPodder (the desktop client) — also runs as a CLI for downloading.
• Podfetch — modern alternative to Podgrab; web UI; auto-download.
  • https://github.com/SamTV12345/PodFetch

Transcription / chapter generation

• ★ whisper.cpp / faster-whisper — see Transcription; generate transcripts locally for the podcast 2.0 <podcast:transcript> tag.
• Podlove Subscribe Button + chapters JSON — podcast 2.0 chapters served alongside the feed.
• Auphonic — closed-source loudness normalization + transcript SaaS; what most indies actually use.

Hosting the audio files

• ★ S3 / R2 / B2 — cheap, durable, CDN-friendly. Most podcast hosts (Castopod, podlove) integrate.
• Self-hosted Garage / MinIO — see Distributed Storage; same S3 API on your own metal.
• Cloudflare R2 — egress-free; pairs beautifully with Castopod.

Patterns to adopt

• ★ Don't lose your back catalog. Mirror your published episodes to a second bucket nightly (rclone / restic).
• Pin episode URLs forever. Once a feed enclosure URL is published, it must keep working — directories cache aggressively.
• Validate the feed. Use Castfeedvalidator / Podbase / castos validator before submitting to Apple / Spotify / Google directories.
• Podcast 2.0 features are free upside — chapters, transcripts, value-for-value all work with Castopod and Podlove out of the box.
• Two HTTPS redirects max — directories follow up to two; more breaks playback on some clients.
• Analytics: opt-in IAB-compliant — Castopod does this correctly; many older tools don't.

Pick this if…

• Default for "I publish a podcast": Castopod.
• WordPress shop: podlove publisher.
• Static-site lover: Hugo / Eleventy + RSS feed + R2 for audio.
• Default for "I listen to podcasts on multiple devices": PinePods or Audiobookshelf.
• Pure subscription sync between mobile clients: gPodder Sync (mygpo) or Nextcloud GPodderSync.
• Auto-download episodes for offline playback: Podgrab or PodFetch.
• YouTube channel → podcast feed: podsync.
