Time to First Byte

lupaxa-time-to-first-byte measures how long an HTTP or HTTPS request takes to receive its first response byte. Each sample resolves the host, connects, negotiates TLS when needed, sends the request, follows redirects, and reports the final response.

pip install lupaxa-time-to-first-byte
ttfb --url https://example.com

A passing sample reports the final status and DNS, connection, TLS, and total TTFB timings. The command repeats until Ctrl-C unless you set --count.
