podpuddle
Self-hosted, nostr-native podcast publishing and livestreaming.
- Log in with nostr — NIP-07 browser extension (Alby, nos2x, …); the server verifies NIP-98 signed requests. No passwords, no email.
- Upload an mp4 → it is stored on a Blossom server
(bundled, or point at any external one) and published in an RSS 2.0 podcast feed with
Podcasting 2.0
<podcast:value>lightning-address payment info. - Go live — stream from OBS (RTMP) or straight from the browser (WebRTC/WHIP) through MediaMTX; viewers watch via HLS and the stream is announced on nostr as a NIP-53 (kind 30311) live event.
- Publish recordings — live streams are recorded; one click remuxes and publishes a recording as a podcast episode.
Quick start
cp .env.example .env # edit PUBLIC_HOST if not localhost
docker compose up --build -d
Then open http://localhost:8095, log in with a NIP-07 extension, and follow the wizard.
Services / ports
| Service | Host port | Purpose |
|---|---|---|
| podpuddle | 8095 | Web UI + API + RSS feeds |
| MediaMTX | 1935 | RTMP ingest (OBS) |
| MediaMTX | 8889 (+8189/udp) | WebRTC/WHIP ingest (browser) |
| MediaMTX | 8890 | HLS playback |
| blossom-server | 8098 | Media blob storage (sha256-addressed) |
Streaming with OBS
Create a stream in the UI; it gives you:
- Server:
rtmp://<host>:1935/live - Stream key:
<streamId>?key=<secret>
The HLS playback URL (http://<host>:8890/live/<streamId>/index.m3u8) is public and never
contains the secret.
Development
docker compose up mediamtx blossom -d # backends
cd server && npm install && npm run dev # API on :8095
cd frontend && npm install && npm run dev # Vite on :5173, proxies /api + /feeds
Tests: cd server && npm test.
Data
Everything lives in named docker volumes: podpuddle-data (SQLite, server nostr key,
covers), mediamtx-recordings (stream recordings, 7-day retention), blossom-data
(media blobs).
