F5Bot alternative for online stores
Short answer: F5Bot is a good keyword alert tool. If you run an online store and want people who are asking to buy what you sell, rather than every mention of a word, Lead Harbour is built for that.
We make Lead Harbour, so we have a bias. We describe F5Bot using what it says about itself as of October 2026. Check their site for current features and prices.
What F5Bot does well
F5Bot is a long-running free service that emails you when your keyword shows up in new Reddit or Hacker News posts and comments. It is free, simple and quick to set up. If you have a handful of distinctive keywords and the time to read every alert, it works.
Where it falls short for online stores
It matches words, not intent. A keyword like "candle" brings back sellers, memes, news and complaints alongside the few people asking to buy, so for a store you end up sorting alerts by hand. It also only covers Reddit and Hacker News.

Common questions
Is F5Bot free?
Yes. F5Bot is a free keyword alert service for Reddit and Hacker News.
Is F5Bot good for finding customers for an online store?
It can catch posts that mention your product word, but it does not tell buyers from sellers or chatter. For a store, you either sort alerts yourself or use a tool that filters for buying intent.
