2XBR CLI is a standalone developer product and the advanced terminal companion to browser-first 2XBR TOOLS. Its first capability is TUNNEL: expose a loopback application through the 2XBR relay for a bounded session, without a required 2XBR account or a background updater.
$2xbr tunnel 3000This stable release is open-source and authenticated by the 2XBR production Ed25519 release key, but its Windows and macOS binaries do not yet have Authenticode or Apple Developer ID signing/notarization.
Windows or macOS may therefore show an unknown-publisher/security warning. Verify the archive SHA-256 and detached release signature before running it. 2XBR does not ask you to disable SmartScreen, Gatekeeper or other operating-system security controls.
These are the exact signed stable assets. Package-manager metadata is included in the signed release set for validation and future publication, but this page does not claim that Homebrew or WinGet channels are already live.

$2xbr tunnel 3000Expose a loopback app on port 3000 through a bounded public HTTPS URL.
$2xbr doctorCheck CLI/platform information, official relay reachability and TUNNEL protocol compatibility without creating a tunnel.
$2xbr versionReport the installed CLI version, TUNNEL wire protocol and target platform.
$2xbr tunnel 443 --host app.test --https --insecure-local-tlsapp.test is only an example loopback hostname. The hostname must resolve exclusively to loopback addresses. --insecure-local-tls is an explicit opt-in for the local self-signed TLS side only.
The TUNNEL operation necessarily sends relayed traffic through the hosted 2XBR relay. The CLI itself has no hidden analytics, background tracking or automatic update check in this release.
Show a local app to another person without deploying it first.
Expose a temporary callback or webhook endpoint during development.
Tunnel ordinary localhost development servers with bounded lifetime.
Keep streaming responses, WebSocket traffic and HMR-compatible flows working.
Generate a local password for a preview when an open public URL is not appropriate.
Target a loopback hostname when your local stack depends on Host/SNI routing.
The detached Ed25519 signature authenticates the signed release statement relative to the production public key. Trust in that public key itself must come from an independent 2XBR trust channel — downloading both the binary and key from this one website is not, by itself, a complete trust bootstrap.

That license applies to the CLI client source and does not automatically license hosted 2XBR services, the production relay, WEB or proprietary platform infrastructure.
The exact source archive also contains a deliberately public test-only Ed25519 private-key fixture for regression tests. It is permanently rejected for consumer trust; the production release private key is external and is not published by WEB.
READ LICENSE →TOOLS / TUNNEL remains the browser-facing product. TOOLS / BRIDGE remains the native companion. CLI remains a separate terminal product that speaks the compatible TUNNEL wire protocol; this WEB positioning does not merge their control, payload or authority semantics.
0.1.0 is the current signed stable CLI release. The previous 0.1.0-rc.1 release remains available at its immutable versioned download path for auditability.
