About F5Bot
Where it came from.
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 if
You have F5Bot watching your product name and two competitors, and the emails have become something you archive without reading.

Where F5Bot wins
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 takes a few minutes: your website, your subreddits, your Reddit account.
Where Reddibee wins
Reasons to switch.
- Signal over volume. Opportunities puts people asking for a tool or an alternative first, not every comment that contains a word.
- It drafts the reply. In your voice, inside the sub’s rules, with your disclosure. You approve it and it goes out from your account.
- Communities, not just mentions. Reddibee tells you where the conversation is and whether you are allowed to join it.
- Your agent can read it too, from Claude Code, Cursor or Claude Desktop.

Questions
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 are not real time: new posts are fetched every few hours, then matched. If you need a notification within minutes of a post, keep F5Bot for that.
Do I need a paid plan for watches?
Yes, watches are part of Pro at $19 a month, up to 100 of them. Opportunities in your tracked subreddits works on every plan, Free included.
