tunneru

tunneru is a lightweight zero-dependency tunneling engine, binary multiplexer, and real-time request inspection suite built in raw go from first principles without using external tunneling services or third-party cloud lock-in. it implements custom stream multiplexing over a single persistent tcp connection using an ultra-compact 9-byte binary frame header with zero-allocation fast-path parsing and sub-millisecond dispatch latency. tunneru provides dual telemetry: an interactive terminal tui built with bubble tea and lipgloss for live request streaming, and a dedicated next.js web dashboard with json tree inspection, raw header diffs, and 1-click webhook replay. it supports instant public subdomain routing and shared token authentication.
