F5Bot

A free monitoring service that emails you the moment your brand or keywords are mentioned on Reddit, Hacker News, or Lobsters.

F5Bot delivers real-time intelligence by scanning major community platforms for specific strings. It checks every new post and comment on Reddit and Hacker News (alongside Lobsters) to ensure you never miss a sales lead or a customer support opportunity. The interface is intentionally minimalist: you enter your keywords, provide an email address, and receive an alert within seconds of a match. It is a lightweight, high-reliability tool for founders and marketers who need to join the conversation exactly when it happens.
