2026-Now
gophoner checks a single phone number against a set of individual modules concurrently, so checking against several services takes about as long as the slowest one, not the sum of them all. It ships both as a scriptable CLI (gophoner check) and a guided terminal UI (gophoner interactive), respectively built with Cobra and Bubble Tea.
It is a spiritual successor to ignorant by Megadose, which was one of the only free and open-source tools to do a similar job.
Overview
None of the supported modules alert or notify the target phone number: no SMS or email is triggered by a check.
Every request is sent with a randomized, internally consistent browser fingerprint (TLS, User-Agent, Client Hints) drawn from a real, hand-made desktop browser pool.
Target numbers are never written to the log file unless --debug is explicitly set.
Users can download it for every platform, from various package managers.
