singboxctl

singboxctl is a TUI for managing:

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

Current Limitations

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

Supported URI subset

VLESS

Currently supported:

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

Unsupported VLESS features fail explicitly.

Hysteria2

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.

Naive

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

Install the CLI globally:

npm install -g singboxctl

Prerequisites

macOS

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

brew install sing-box

Run

Start the TUI with:

singboxctl

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

singboxctl connect

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

Current Menu

The current TUI includes:

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

Notes

• 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.
• 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.
• Auto-start in background enables or disables running sing-box in the background now and on future startups.
