Is a free bot detection script safe to add to my site?

BotRefund provides a lightweight client‑side script that loads asynchronously after the page renders, adding zero milliseconds to the critical path. The code is open for inspection and collects only the signals needed for bot analysis, respecting privacy regulations. Because it runs in the browser it does not require any server changes or credentials. This makes it a safe option for most websites looking to start detecting fraudulent clicks.
