Reddibee vs F5Bot
Free keyword alerts for Reddit and Hacker News. Good at the one thing it does, and it stops there.
Free plan: 10 requests a day, no card.
F5Bot is a free service that emails you when a keyword you chose appears in a Reddit post or comment, on Hacker News, or on Lobsters. It has run for years, it is reliable, and it is a plain keyword match with no ranking or filtering.
This page is for you ifYou have F5Bot watching your product name and two competitors, and the emails have become something you archive without reading.

Reasons to stay.
- It is free with no cap. If a raw firehose of every mention is what you want, F5Bot delivers it and Reddibee charges for volume.
- Lobsters. Reddibee does not read it.
- Zero setup. An email address and a keyword. Reddibee needs an agent that speaks MCP.
Reasons to switch.
- Signal over volume. A watch on "Cursor" returns complaints and people looking for alternatives, not every comment that contains the word.
- You can ask follow-ups. "Which of these are from people who already pay?" is one more request, not another inbox search.
- Communities, not just mentions. Reddibee tells you where the conversation is and whether you are allowed to join it.
- Your agent gets the alerts too, so it can draft the reply, the changelog entry, or the tweet.

Ask the question the emails never answered
"What changed in how people talk about us this month?" One request, cited.
Asked by people switching.
Does Reddibee catch mentions in comments, or only posts?
Both. Threads are fetched with their comment tree, and each comment is classified on its own.
How fast is a watch compared with an F5Bot email?
Watches run on a schedule, not in real time, and batch new matches into one email. If you need a notification within minutes of a post, keep F5Bot for that.
Do I need a paid plan for watches?
Free includes one watch. Email alerts and more watches start on Starter at $9 a month.
