KoalaCast

A completely free, open-source, privacy-first podcast player for the web.

Why KoalaCast 100% free and open source — MIT licensed, no ads, no tracking, no premium tier. Local-first — use the entire app with no account; data lives in your browser's IndexedDB. Optional cross-device sync — an account syncs subscriptions, favorites, playback progress, and listening statistics. Direct publisher audio by default — playback streams straight from the publisher CDN. Self-hosters can opt into an audio relay for browser effects/downloads blocked by publisher CORS. RSS as the source of truth — standard RSS 2.0/Atom plus Podcasting 2.0 tags are preserved. Self-hosting parity — a self-hosted instance has exactly the same capabilities as any official one.
