This page lists every port used by atl.chat services, verified against the current compose.yaml and infra/compose/*.yaml files. All host-side ports are configurable via environment variables in .env.
IRC stack
Defined in infra/compose/irc.yaml.
| Port | Env Variable | Service | Protocol | Bind address | Description |
|---|
6697 | IRC_TLS_PORT | UnrealIRCd | TCP | ATL_CHAT_IP | IRC over TLS — primary client connection |
8000 | IRC_WEBSOCKET_PORT | UnrealIRCd | TCP | ATL_CHAT_IP | IRC WebSocket for web clients |
8600 | IRC_RPC_PORT | UnrealIRCd | TCP | ATL_CHAT_IP | JSON-RPC API (used by WebPanel and tooling) |
6900 | IRC_SERVER_PORT | UnrealIRCd | TCP | ATL_CHAT_IP | Server-to-server links |
8081 | ATHEME_HTTPD_PORT | Atheme | TCP | ATL_CHAT_IP | Atheme HTTP API (Atheme shares the IRC server’s network namespace) |
8080 | WEBPANEL_PORT | WebPanel | TCP | 0.0.0.0 | UnrealIRCd admin web panel |
ATL_CHAT_IP (default 127.0.0.1). The WebPanel port binds to all interfaces (0.0.0.0) and does not use ATL_CHAT_IP.
Atheme uses network_mode: service:atl-irc-server, so it shares the IRC server’s network stack. The Atheme uplink port (6901) is internal to that shared namespace and not exposed to the host.
XMPP stack
Defined in infra/compose/xmpp.yaml.
| Port | Env Variable | Service | Protocol | Description |
|---|
5222 | PROSODY_C2S_PORT | Prosody | TCP | XMPP client-to-server (STARTTLS) |
5223 | PROSODY_C2S_DIRECT_TLS_PORT | Prosody | TCP | XMPP client-to-server (Direct TLS) |
5269 | PROSODY_S2S_PORT | Prosody | TCP | XMPP server-to-server federation |
5270 | PROSODY_S2S_DIRECT_TLS_PORT | Prosody | TCP | XMPP server-to-server (Direct TLS) |
5280 | PROSODY_HTTP_PORT | Prosody | TCP | HTTP — BOSH and WebSocket endpoints |
5000 | PROSODY_PROXY65_PORT | Prosody | TCP | SOCKS5 bytestream proxy for file transfers |
5281 | PROSODY_HTTPS_PORT | Nginx (XMPP) | TCP | HTTPS reverse proxy for Prosody |
443 | (see note) | Nginx (XMPP) | TCP | 127.0.0.1:443 only — same vhost/certs as 5281; clients that use https://<XMPP_DOMAIN>/… with no port (e.g. Fluux discovery, wss://<domain>/ws) hit this |
Web clients
| Port | Env Variable | Service | Compose File | Description |
|---|
9000 | THELOUNGE_PORT | The Lounge | infra/compose/thelounge.yaml | Web IRC client (private mode, requires user account) |
8090 | OBSIDIANIRC_PORT | ObsidianIRC | infra/compose/obsidianirc.yaml | Modern web IRC client (custom build, single-server mode) |
Bridge
Defined in infra/compose/bridge.yaml. The bridge service does not expose any host ports — it connects outbound to IRC, XMPP, and Discord over the atl-chat Docker network and the internet.
Dev-only services
Available when running just dev (activates the dev Docker Compose profile).
| Port | Env Variable | Service | Description |
|---|
8082 | DOZZLE_PORT | Dozzle | Docker log viewer (container port 8080 mapped to host 8082) |
TURN/STUN (standalone)
Deployed separately via infra/turn-standalone/compose.yaml using host networking. Not part of the main compose.yaml stack.
| Port | Protocol | Service | Description |
|---|
3478 | TCP/UDP | Coturn | STUN/TURN relay |
5349 | TCP | Coturn | TURNS (TLS) |
49152–49202 | UDP | Coturn | Media relay port range |
Services not in Docker Compose
These services run outside the Docker stack during development:
| Port | Service | Description |
|---|
3000 | Next.js web app | Run locally with pnpm dev in apps/web/ |
Customising ports
Every host-side port is controlled by an environment variable in .env. To change a port, set the variable before starting the stack:
# Example: move IRC TLS to port 6698
IRC_TLS_PORT=6698
ATL_CHAT_IP (default 127.0.0.1), which controls the bind address. Set it to 0.0.0.0 to listen on all interfaces in production.
See the environment variables reference for the full list.
