You want email alerts for brand names, competitor complaints, recommendation requests, or pain-point keywords—and a person will review every match.
F5Bot
⚡ Best low-cost Reddit & HN mention alertUse F5Bot when your job is to catch a small number of relevant Reddit, Hacker News, or Lobsters mentions and respond manually. Do not buy a broad listening suite until you need more channels, analytics, collaboration, or automated routing.
Know whether to keep reading.
You need X, LinkedIn, YouTube, news coverage, sentiment charts, team dashboards, or one system for company-wide social intelligence.
Cheap and focused—not a listening suite.
- Monitors Reddit posts and comments, Hacker News, and Lobsters from one keyword setup.
- Starts free for personal use; the first professional step is $9.99/month.
- No dashboard habit required: relevant matches arrive by email.
- Paid filters can narrow alerts by subreddit, URL, and included or excluded terms.
- No monitoring for X, LinkedIn, YouTube, mainstream news, or the wider web.
- The free plan is personal-use only and can take up to two hours to alert.
- No sentiment analysis, trend charts, executive reporting, or collaborative inbox.
- Slack/Discord, AI filtering, instant alerts, API, and webhooks require higher tiers.
Pay only when the workflow changes.
The free plan is for personal use. Compare the operational trigger—not only the keyword limit.
