Archipelago's current provider (served from ARCHIPELAGO_PROVIDER_PATH) also runs in a top-level tab: it replaces window.nostr and routes signing to <origin>/nostr-signer, which only the node dashboard serves. Opened directly, e.g. on a public hostname, that hid the browser's NIP-07 extension and login failed with "NIP-07 timeout". The bundled copy was a no-op outside an iframe, which is what index.html assumed. Load the provider only when framed, via document.write so it stays a blocking script that runs before the app and keeps document.currentScript for its data-* settings.

podsteadr
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 |
|---|---|---|
| podsteadr | 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: podsteadr-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.
Source and Archipelago packaging
The source of truth is the nostr git (ngit) repo
nostr://npub1krldcq2laqxeslseue8uyk24vg6mhmv0ra6ldc52hyfwdx5azd8se5j65x/relay.ngit.dev/podsteadr
(browse on gitworkshop.dev);
a Gitea copy is kept as a mirror. Cloning needs ngit's git-remote-nostr.
podsteadr is packaged for Archipelago in the archy repo (apps/podsteadr*),
together with the player from podsteadr-player. When a change here affects
what those manifests describe — Dockerfile, env vars, ports, data paths,
container names, blossom/mediamtx config — update archy too:
.claude/skills/archy-integration/SKILL.md
lists which archy files follow which files here.
