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). docker compose down keeps them; down -v wipes them.

Verification

• Unit tests: cd server && npm test (35 tests).
• Against a running stack: node scripts/e2e.mjs (14 checks: login, blossom upload, feed, stream keys, MediaMTX auth webhook).

Status & internals

See docs/STATUS.md for the architecture, the full verification record, known gotchas (blossom v4 config nesting, no range requests, split-horizon blossom URL, MediaMTX polling rationale), and the remaining-work list (Archipelago packaging, git remote).
