F5Bot vs SubredditStats in 2026: real-time mention alerts vs free subreddit research
F5Bot emails you within minutes when your keywords show up on Reddit, Hacker News, or Lobsters, for free. SubredditStats never alerts on anything: it is a free, no-login site for sizing up subreddit growth, overlap, and activity before you decide where to point a monitoring tool in the first place.
F5Bot
SubredditStats- F5Bot delivers email alerts within minutes on a genuinely functional free tier, no credit card required. SubredditStats has no alerting feature at all, on any plan, because there is no plan beyond free.
- SubredditStats covers Reddit only. F5Bot covers Reddit plus Hacker News and Lobsters, then gates AI semantic alerts, the REST API, and Slack or Discord routing behind its $58.33/month Ultra plan.
- SubredditStats' community overlap analysis and keyword frequency tracking over time have no equivalent anywhere in F5Bot, which only matches exact keywords (or AI-described intent on Ultra) and never analyses subreddit-to-subreddit audience overlap.
- SubredditStats explicitly warns on its own homepage that its data collector "is not robust" and calls itself a hobby project with no SLA. F5Bot carries no such disclaimer and has run continuously since 2017.
- Neither tool gives most users an API. SubredditStats never offers one, on any plan, ever. F5Bot's REST API and webhooks are Ultra-plan-only at $58.33/month.
- SubredditStats recommends F5Bot by name in its own FAQ for teams that need active brand-mention monitoring, since SubredditStats itself does not send notifications of any kind.
- F5Bot's free tier limits how many keywords you can track as your needs grow. SubredditStats has no such ceiling, but also nothing to track beyond browsing and frequency charts, since there is no account system or keyword-alert product to gate.
F5Bot and SubredditStats both live in the free-Reddit-tool corner of the internet, but they answer different questions at different points in a workflow. F5Bot answers "did anyone just mention my brand," watching Reddit, Hacker News, and Lobsters continuously and emailing you within minutes of a match, no credit card required. SubredditStats answers "which subreddits are actually worth watching," a static research site with growth charts, subscriber rankings, and community overlap analysis, no monitoring or alerting feature anywhere on it. One is reactive and built to notify; the other is upfront research and built to inform a decision before you commit to anything. SubredditStats even says as much in its own FAQ, pointing readers toward F5Bot when they ask about active mention monitoring. Anyone comparing these two directly is usually trying to figure out whether they need to be alerted or whether they need to do homework first.
The tools at a glance
F5Bot
Know within minutes when your brand gets mentioned on Reddit, Hacker News, or Lobsters
F5Bot does one job: it watches Reddit, Hacker News, and Lobsters for keywords you specify and emails you within minutes of a match. Setup takes under a minute, there is nothing to configure beyond adding terms, and the service has run continuously since 2017, which counts for something when you are trusting a tool to actually catch mentions as they happen rather than on a delayed digest.
The free tier is not a stripped-down trial. It works with no credit card and covers the core job of catching brand and competitor mentions in real time. Paid tiers layer on advanced filtering by subreddit and co-occurring terms, RSS and JSON feeds on the Power plan, and on Ultra, AI semantic alerts that match intent described in plain language instead of exact keyword strings, plus a full REST API with webhooks and Slack or Discord routing.
What F5Bot does not do is anything resembling research. There is no subreddit ranking, no growth chart, no overlap analysis, nothing to help you decide which communities are worth watching in the first place. It assumes you already know your keywords and just want to be told the moment they appear.

SubredditStats
Free subreddit analytics with growth charts, subscriber rankings, and community overlap analysis
SubredditStats is a free, no-login site for sizing up Reddit communities before you invest time in them. Browse rankings by subscriber count, growth rate, posts per day, or comments per day, and clicking into any individual subreddit pulls up historical growth and activity charts that go back months or years for established communities.
The two features worth bookmarking the site for are community overlap analysis and keyword frequency tracking. Overlap analysis shows which other subreddits share a significant portion of users with a given community, useful for finding adjacent audiences you had not thought to target. Keyword frequency tracking shows how often a term shows up in a subreddit's comments over time, which can validate that a niche is actively discussed or catch a topic trending before it peaks. Network visualizations round this out by mapping related subreddits graphically.
The site is upfront about its limits: the maintainer describes it as a hobby project and warns directly on the homepage that the data collector is not robust, so numbers should be treated as directional rather than precise. There is no API, no data export, and critically, no monitoring or alert feature, so every use is a manual visit to the web interface rather than something running in the background.

Which should you choose?
F5BotSubredditStatsSubredditStatsF5BotF5BotSubredditStatsF5BotThese two are not competing for the same job. F5Bot is reactive: it assumes you already know your keywords and exists purely to tell you the moment they appear somewhere. SubredditStats is upfront research: it helps you decide which communities deserve attention in the first place, then gets out of the way, since it has no mechanism for ongoing monitoring at all. The overlap is thin enough that SubredditStats' own FAQ points readers to F5Bot when they ask about mention alerts, which tells you how the maintainer sees the two tools fitting together.
Bottom line
If you are starting from zero, use SubredditStats first. It costs nothing, requires no signup, and tells you which subreddits are actually large and active enough to be worth watching. Once you know where to look, set up F5Bot to catch mentions in those communities as they happen, starting on the free tier and moving to Ultra only if you need AI semantic matching or the REST API. Treat SubredditStats' numbers as directional given the maintainer's own accuracy disclaimer, and do not expect either tool to do the other's job.
Frequently asked questions
Should I use F5Bot or SubredditStats to find out if people are talking about my brand on Reddit?
Use F5Bot for that specifically, since it is the tool built to alert you by email within minutes of a keyword match on Reddit, Hacker News, or Lobsters. SubredditStats has no mention-monitoring or alerting feature at all; it is a static analytics site for researching subreddit size and growth, not for tracking your brand.
Does SubredditStats send alerts like F5Bot does?
No. SubredditStats has no notification system of any kind, on its free tier or otherwise, since it does not have a paid tier either. It is a browse-and-research tool, and its own FAQ directs users who want active monitoring to a tool like F5Bot instead.
Is F5Bot's free plan good enough or do I need to pay for Ultra?
F5Bot's free plan is genuinely functional and covers the core job of real-time email alerts with no credit card required. You only need Ultra at $58.33/month if you specifically want AI semantic alerts that match described intent rather than exact keywords, the REST API, or Slack and Discord routing.
How accurate is the data on SubredditStats?
SubredditStats' own homepage warns that its data collector is not robust and that the numbers should be treated as a general guide rather than precise figures. It is a hobby project maintained by one person with no SLA, so use it for directional research and verify anything that matters for a major decision with a second source.
Can I use F5Bot and SubredditStats together?
Yes, and that is arguably the intended workflow. Use SubredditStats first to identify which subreddits are large, active, and audience-relevant, then set up F5Bot to monitor keywords within and around those communities so you find out the moment something worth responding to appears.
Which tool covers more than just Reddit, F5Bot or SubredditStats?
F5Bot covers more ground: it monitors Hacker News and Lobsters in addition to Reddit, all on the same free tier. SubredditStats is Reddit-only across every one of its features, including growth charts, rankings, and community overlap analysis.
