TinyIce

One binary. Audio and video. Scales to six figures of listeners.

Icecast-compatible streaming server with RTMP/SRT/WebRTC ingest, pure-Go audio transcoding, HLS audio+video output, an AutoDJ with MPD remote control, and a built-in admin SPA. Deploy anywhere in seconds.

Why TinyIce

• One binary, no runtime dependencies. Pure-Go SQLite, pure-Go audio decode/encode, embedded frontend — no FFmpeg, no GCC, no separate database. Cross-compiles to Linux, macOS, Windows, and FreeBSD.
• Faces the internet directly. Built-in ACME (Let's Encrypt) terminates TLS, and the shared circular-buffer broadcast path serves large listener counts from a single process. Run it straight on 80/443 — no reverse proxy required.
• Icecast-compatible, not Icecast-bound. Existing encoders and players keep working; HLS and WebRTC are layered on top for modern clients.
• Secure defaults. Credentials are generated on first run, mutating admin actions are CSRF-protected, outbound webhook/relay URLs are SSRF-guarded, and the packaged systemd unit ships masked so an unconfigured daemon can't auto-start.

Quick start

1. Install

# Released binary
curl -LJO "https://github.com/DatanoiseTV/tinyice/releases/latest/download/tinyice-$(uname -s | tr '[:upper:]''[:lower:]')-$(uname -m)"
chmod +x tinyice-*&& mv tinyice-* tinyice && ./tinyice
# Or Docker — multi-arch images on GHCR (linux/amd64, linux/arm64)# The image listens on 8080 and reads /data/config.json; reach it on :8000
docker run --rm -p 8000:8080 -v tinyice-data:/data ghcr.io/datanoisetv/tinyice:latest
# Or from source — Go 1.25+, Node 20+
git clone https://github.com/DatanoiseTV/tinyice.git &&cd tinyice && make build

.deb / .rpm packages are attached to every release. Full matrix and options: Installation.

2. First run

On first start TinyIce prints generated credentials once — save them:

FIRST RUN: SECURE CREDENTIALS GENERATED
Admin Password: Oy9…
Default Source Password: Rm3…
Live Mount Password: 8fX…

Then open http://localhost:8000 (and /admin to log in as admin).

3. Stream

Source	How
BUTT / Mixxx / LadioCast	Icecast 2 · server host:8000 · mount /live · password = Live Mount Password
OBS	See below
FFmpeg	ffmpeg -re -i input.mp3 -f mp3 -content_type audio/mpeg icecast://source:<pw>@host:8000/live
SRT	srt://host:9000?streamid=#!::r=live,m=publish,key=<pw> from OBS, ffmpeg, or a DVB mux
Browser	Admin → Go Live for WebRTC mic/line broadcasting
Files	Configure an AutoDJ pointed at a directory of audio files

Stream video from OBS

TinyIce accepts H.264 + AAC (or H.264 + MP3) over RTMP and produces HLS audio + video at /<mount>/playlist.m3u8.

1. Enable RTMP in tinyice.json:

   "ingest": { "rtmp_enabled": true, "rtmp_port": "1935" }

2. Create a mount in Admin → Streams → Add Mount. The password is your OBS Stream Key.
3. OBS → Settings → Stream (Service: Custom): Server rtmp://<host>/<mount> (e.g. rtmp://radio.example.com/live), Stream Key = the mount's source password.
4. OBS → Settings → Output: video x264 (or hardware H.264), audio AAC or MP3, 1 s keyframe interval (matches the default segment size for lowest latency).
5. Start Streaming. The log shows RTMP: Publishing started and Parsed AVC config.
6. Watch it:
   • Browser playerhttps://<host>/player/<mount> — 16:9 layout, STATS overlay (codec/res/fps/GOP/bitrate, dropped frames, buffer, latency), live viewer count.
   • Direct HLShttps://<host>/<mount>/playlist.m3u8 — VLC, mpv, ffplay, Safari, iOS.
   • WebRTC (sub-second, opt-in) — append ?webrtc=1 to the player URL; requires a B-frame-free encoder (bf=0).

Deploy

TinyIce is a single static binary with the admin UI, player, and assets embedded.

• Direct / ACME: enable auto_https, list your domains, and run on 80/443. TinyIce obtains and renews Let's Encrypt certificates itself. A reverse proxy is optional, not required.
• Docker: multi-arch images on GHCR — :latest, :beta, :vX.Y.Z, :X.Y, :X.
• Packages:.deb / .rpm install a hardened systemd unit, a dedicated tinyice user, and /etc/tinyice + /var/lib/tinyice. The unit ships masked by design — unmask, then enable --now.
• Zero-downtime: hot-swap the binary (SO_REUSEPORT) or reload config with SIGHUP. There is no in-process self-updater — update by replacing the binary, pulling a new image, or apt/dnf upgrade.

Sizing, reverse-proxy notes, and ACME details: Deployment.

Develop

Requires Go 1.25+ and Node.js 20+.

make build # frontend + Go binary
make generate # frontend only (go generate ./server/...)
make quick # Go-only (reuse existing dist/)
make dev # Vite frontend dev server (hot reload)

Frontend is Preact + @preact/signals + Vite in server/frontend/src/; all dist assets are embedded into the Go binary via go:embed, so the released binary is self-contained. See Developing and Architecture.
