F5Bot vs SubredditSignals in 2026: free mention alerts vs paid buyer-intent lead generation
F5Bot is a free, no-frills keyword alert service for Reddit, Hacker News, and Lobsters. SubredditSignals is a paid Reddit lead-generation platform that scores buyer intent across 7 dimensions and drafts replies for you, starting at $29/mo.
F5Bot
SubredditSignals- SubredditSignals classifies every post across 7 buyer-intent dimensions and separates out Purchase-Ready leads. F5Bot has no intent classification; every keyword match arrives with equal weight.
- F5Bot's free tier costs $0 with no credit card required. SubredditSignals starts at $29/mo (Starter) with a 14-day free trial and no credit card required to begin it.
- SubredditSignals explicitly uses the official Reddit API, a compliance point it calls out directly after GummySearch's shutdown left tools built on unofficial data sources exposed.
- SubredditSignals Pro ($59/mo) includes a first-party attribution pixel tracking Reddit and AI traffic across ChatGPT, Perplexity, Gemini, Copilot, and Claude. F5Bot has no attribution or AI-engine tracking of any kind.
- F5Bot's REST API is available on its Ultra plan at $58.33/mo. SubredditSignals does not mention API access on either the Starter or Pro plan.
- SubredditSignals includes Comment Builder with Voice Profiles and buyer intent classification on both its Starter and Pro plans. F5Bot restricts its AI semantic matching and Slack/Discord routing to the Ultra plan.
F5Bot and SubredditSignals both start from the same idea, watch Reddit for mentions, but they are built for different jobs once a mention shows up. F5Bot tells you a keyword matched and leaves everything else to you: reading the thread, deciding whether it matters, and writing a reply. SubredditSignals reads the thread for you, scores how close the poster is to buying something, separates out the Purchase-Ready conversations, and helps draft a reply in your own voice. F5Bot is free and asks nothing of you beyond setting keywords. SubredditSignals costs $29 to $59 a month and asks you to trust its intent scoring, in exchange for cutting the daily triage work down to almost nothing. The right pick depends on whether Reddit is a nice-to-have listening channel or an active lead source you are trying to scale.
The tools at a glance
F5Bot
Know within minutes when your brand gets mentioned on Reddit, Hacker News, or Lobsters
F5Bot has run the same simple service since 2017: watch Reddit, Hacker News, and Lobsters for the keywords you give it, and email you within minutes when one appears. There is no scoring, no drafting, and no prioritization, just a fast, dependable notification.
The free tier is not a limited trial. It requires no credit card and covers the core alerting need for solo founders and small teams. Paid tiers add subreddit and co-occurring-term filtering, RSS and JSON feeds, and on the Ultra plan, natural-language semantic alerts, a REST API, and Slack or Discord routing.
What F5Bot does not do is help you figure out which of those mentions actually matter. A keyword match from someone casually name-dropping your product looks identical to one from someone actively comparing options and ready to buy; sorting that out is left entirely to the person reading the alert.

SubredditSignals
Real-time Reddit buying-intent scanner with AI-drafted comment suggestions
SubredditSignals starts from the same monitoring foundation as a keyword alert tool but adds a layer most competitors skip: every post is scored across 7 buyer-intent dimensions before it reaches your feed, so someone asking a casual question and someone announcing they are canceling a competitor's subscription do not land in the same bucket. Purchase-Ready leads are separated out explicitly.
Comment Builder with Voice Profiles helps draft a reply that sounds like a specific person rather than a template, which matters because copy-paste AI comments tend to get downvoted or flagged on Reddit. Subreddit Discovery finds relevant communities you would not have thought to monitor, and the Pro plan adds a first-party attribution pixel tracking which subreddits and AI engines, including ChatGPT, Perplexity, Gemini, Copilot, and Claude, actually drive conversions.
The platform runs on Reddit's official API by design, a detail it highlights directly given how many Reddit marketing tools lost access when GummySearch was shut down for relying on unofficial data. Starter is $29/mo and Pro is $59/mo, both with a 14-day free trial and no credit card required to start, though Starter caps Purchase-Ready leads at 3 per week.

| Purchase-Ready leads | 3/week | Unlimited |

Considering AI Peekaboo alongside F5Bot and SubredditSignals?
SubredditSignals Pro tracks referral traffic from ChatGPT, Perplexity, Gemini, Copilot, and Claude once someone has already clicked through to your site, and F5Bot does not track AI engines at all. Neither tool tells you whether those AI engines are actually mentioning or recommending your brand inside an answer before that click happens. AI Peekaboo monitors brand citations across those same engines directly, showing whether you are mentioned or recommended in AI-generated answers rather than only measuring the traffic that shows up afterward.

F5BotSubredditSignalsF5BotSubredditSignalsF5BotSubredditSignalsSubredditSignalsSubredditSignals scores higher across the board because it does more, but that extra work is exactly what its $29 to $59 monthly price is paying for. F5Bot's free tier is not a lesser version of the same product; it is a genuinely different, narrower tool that happens to cost nothing. For a team that treats Reddit as one channel among several and just wants to know when they are mentioned, paying for intent classification is unnecessary. For a team actively working Reddit as a lead source, manually triaging every F5Bot alert becomes the bottleneck that SubredditSignals is built to remove.
Bottom line
If Reddit is a channel you glance at occasionally, F5Bot's free tier is enough and there is no reason to pay for more. If Reddit is a lead source you are actively working, SubredditSignals' $29/mo Starter plan is worth it the moment manual triage starts eating more than a few minutes a day, and the 14-day trial with no credit card makes it cheap to find out. Teams already burned by GummySearch's shutdown should also weigh SubredditSignals' official-API compliance as a real point in its favor, not just a footnote.
Frequently asked questions
Does SubredditSignals do everything F5Bot does, plus more?
Mostly yes for Reddit specifically: SubredditSignals monitors Reddit with buyer-intent scoring on top, which covers what F5Bot's Reddit alerts do and adds triage. The one thing F5Bot covers that SubredditSignals does not is Hacker News and Lobsters, since SubredditSignals is Reddit-only.
Is SubredditSignals worth paying for instead of using F5Bot for free?
SubredditSignals earns its $29/mo once mention volume turns manual triage into a daily time cost, since its buyer-intent classification and Purchase-Ready filtering remove that sorting work. If Reddit mentions of your brand are rare enough to read one by one, F5Bot's free alerts cover the need without a subscription.
Why does SubredditSignals mention the official Reddit API so specifically?
SubredditSignals calls out its use of Reddit's official API because GummySearch, a competing Reddit tool built on unofficial data access, was shut down, leaving its users without a working product. SubredditSignals treats API compliance as a design constraint to avoid the same fate, not just a technical footnote.
Does F5Bot offer buyer intent scoring like SubredditSignals?
No, F5Bot has no intent classification of any kind. It alerts on every keyword match with equal priority, so distinguishing a casual mention from a purchase-ready conversation has to be done manually by whoever reads the alert.
Which tool has a REST API, F5Bot or SubredditSignals?
F5Bot offers a REST API and webhook delivery on its Ultra plan at $58.33/mo. SubredditSignals does not mention API access on either its Starter or Pro plan, so it is used through its own interface rather than integrated into external dashboards.
Can SubredditSignals show whether ChatGPT or Gemini are sending traffic from Reddit threads?
Yes, but only on the Pro plan at $59/mo, where a first-party attribution pixel tracks conversions by subreddit and by AI engine, including ChatGPT, Perplexity, Gemini, Copilot, and Claude. F5Bot has no attribution or AI-engine tracking on any plan.
