How Relevyn Layers Rate Limits to Protect Its Free AI Audit Tool From Abuse

Relevyn offers a no-signup, free AI-visibility audit tool where users enter a brand and website to receive an instant check, but the open-access model creates significant abuse risks. A single per-IP daily cap can block one bad actor but fails against distributed scripts using hundreds of different addresses, while a global daily ceiling alone can be exhausted by one aggressive user before genuine visitors get access. To address both threat shapes, Relevyn layers the two controls: a global hard cap prevents catastrophic cost overruns, while a per-IP limit deters single-machine scripting. The team notes there is no formula for choosing the right numbers — initial limits are essentially informed guesses that must be revised once real traffic data becomes available. The broader takeaway is that rate limits should be treated as testable hypotheses rather than fixed configurations set at launch.
