pi-web

A web UI for the pi coding agent.

Usage

npx -y pi-web@latest

Then open http://127.0.0.1:8192 in your browser.

For remote access, use the recommended Tailscale HTTPS setup below.

Options

--port <number>      Port to listen on (default: 8192)
--host <string>      Host to bind to (default: 127.0.0.1)
--help               Show help

Recommended: secure access with Tailscale (HTTPS, no app password)

pi-web does not include built-in authentication. Recommended setup: keep it bound to 127.0.0.1 (IPv4 loopback) and expose it only through your private Tailnet.

1. Start pi-web locally (default host is already 127.0.0.1):

npx -y pi-web@latest --host 127.0.0.1 --port 8192

2. In another terminal, expose it over Tailnet HTTPS using one of these bindings:

Without specifying an HTTPS port (default HTTPS binding):

tailscale serve --bg 8192

• Open in browser: https://<your-device>.<your-tailnet>.ts.net/

With an explicit HTTPS port binding (example: expose on Tailnet 8192):

tailscale serve --bg --https=8192 http://127.0.0.1:8192

• Open in browser: https://<your-device>.<your-tailnet>.ts.net:8192/

• Prefer the explicit form when you want a non-default Tailnet HTTPS port, or when you want to avoid localhost/::1 resolution ambiguity.

3. Check the HTTPS URL and serve status:

tailscale serve status

4. To stop exposing the service:

tailscale serve reset

Notes:

• This is accessible only to devices/users authorised in your Tailnet (and ACLs), so no separate pi-web password is required.
• Use 127.0.0.1 explicitly rather than localhost for --host and local proxy targets; on some systems localhost resolves to ::1 (IPv6), which can break loopback forwarding expectations.
• Avoid binding pi-web to 0.0.0.0 when using this setup.
• Do not use tailscale funnel unless you explicitly want public internet exposure.
