singboxctl is a TUI for managing:

• Xray-compatible connection URIs
• routing profiles
• sing-box match rules

• Supported operating systems: macOS and Linux
• Connection import currently supports a narrow subset of these URI protocols:
  • vless://
  • trojan://
  • hysteria2://
  • tuic://
  • naive+https://
  • naive+quic://
• Supported rule formats are currently domain:..., domain_suffix:..., and ip_cidr:...
• Unsupported URI or rule features fail explicitly instead of being guessed

Currently supported:

• type=tcp
• security=none|reality
• REALITY with flow=xtls-rprx-vision

Unsupported VLESS features fail explicitly.

Currently supported:

• type=tcp
• security=reality
• REALITY with required pbk and sni
• optional sid
• optional fp

For Trojan URIs, the password is read from the URI userinfo segment:

trojan://<password>@example.com:443?...

Provider links in the wild may also include extra Trojan parameters such as spx. Provider-link fields are documented separately from guaranteed generated sing-box runtime support: if a field is not listed above in the supported subset, do not assume it is applied to config.json just because it appears in a provider URI.

Currently, spx is accepted with a warning and is not applied to the generated sing-box config.

Unsupported Trojan features fail explicitly.

Currently supported:

• security=tls
• optional sni
• alpn=h2|h3

For Hysteria2 URIs, the auth value is read from the URI userinfo segment:

hysteria2://<auth>@example.com:443?...

Provider links in the wild may also include extra Hysteria2 parameters such as fp. Provider-link fields are documented separately from guaranteed generated sing-box runtime support: if a field is not listed above in the supported subset, do not assume it is applied to config.json just because it appears in a provider URI.

Unsupported Hysteria2 features fail explicitly.

Currently supported:

• TUIC v5 userinfo tuic://<uuid>:<password>@example.com:443?...
• optional sni
• optional alpn (comma-separated)
• optional congestion_control=cubic|new_reno|bbr
• optional udp_relay_mode=native|quic
• allow_insecure=0 (insecure TLS is rejected)

TLS is always enabled. TUIC requires sing-box 1.4.0 or newer.

Unsupported TUIC features fail explicitly.

Currently supported:

• naive+https:// and naive+quic://
• username and password in URI userinfo
• optional sni
• optional extra-headers
• optional generated udp_over_tcp: true when enabled during Select connection and profile

For Naive URIs, the auth values are read from the URI userinfo segment:

naive+https://<username>:<password>@example.com:443?...

Provider links in the wild may also include extra Naive parameters such as padding. Provider-link fields are documented separately from guaranteed generated sing-box runtime support: if a field is not listed above in the supported subset, do not assume it is applied to config.json just because it appears in a provider URI.

Currently, padding is accepted with a warning and is not applied to the generated sing-box config.

Unsupported Naive features fail explicitly.

Install the CLI globally:

npm install -g singboxctl

• Install Homebrew: https://brew.sh/
• Install sing-box with:

brew install sing-box

• Install sing-box using its official package instructions: https://sing-box.sagernet.org/installation/package-manager/
• Background service management requires a running systemd and systemctl.
• Non-root service management requires sudo.
• Opening files and directories requires xdg-open, usually provided by xdg-utils.

singboxctl installs and manages its own singboxctl.service system service. If the package-provided service is active, disable it first to avoid competing TUN interfaces:

sudo systemctl disable --now sing-box

Start the TUI with:

singboxctl

Or start sing-box directly with the currently applied config:

singboxctl connect

Generate a config for a specific profile using the active connection:

singboxctl generate main
singboxctl generate main ./artifacts/router-config.json

The optional output path creates missing parent directories. Generation requires the saved active connection and requested profile, but does not require the local sing-box runtime, change the active profile, or restart the service.

If sing-box is not available yet, the app will show an error with installation hints.

The current TUI includes:

• Auto-start in background
• Connect in terminal
• Select connection and profile
• Connections
• Profiles
• Rule Sets
• IPv6
• Logs

• Connections store raw Xray-compatible URIs.
• Rule Sets store named groups of rules. The rule-set file name is the source of truth for the rule-set name.
• Profiles select which rule sets should be active.
• Select connection and profile validates the selected connection with the built-in URI parsers, writes a generated TUN config to ~/.config/singboxctl/config.json, and refreshes the running service when needed.
• generate <profile> [output-path] uses the active connection and writes the selected profile's config to the standard path or an explicit path without changing the active selection.
• Connect in terminal starts sing-box in the foreground using the currently applied ~/.config/singboxctl/config.json and prints logs in the current terminal. This is mainly useful for debugging.
• Logs opens or clears /var/log/singboxctl.log and lets you change the sing-box log level. On Linux, the file opens through the default desktop application registered with xdg-open.
• Auto-start in background enables or disables running sing-box in the background now and on future startups.
