How to set up F5Bot for brand monitoring on Reddit
F5Bot is a free service that emails you whenever your keywords appear on Reddit, Hacker News, or Lobsters. It has been running for nine years, sends more than 175,000 alerts per day, and replaces a $500 to $5,000 per month enterprise listening tool for the specific use case of brand keyword alerting. We deploy it on day one for every branded subreddit engagement we run. Here is the exact setup.
What F5Bot is
F5Bot is a keyword alerting service at f5bot.com. You give it keywords, it scans public posts and comments on Reddit, Hacker News, and Lobsters in near real time, and it emails you whenever one matches. It supports up to 200 keywords per account, and per the F5Bot FAQ, it has been running for nine years and sends over 175,000 alerts per day across all users. There is no dashboard, no sentiment analysis, no account manager. Email in, email out, which is why it has survived nine years while fancier tools churned.
Why brands love it
The value-to-cost ratio is unmatched. F5Bot is free up to 200 keywords. Comparable monitoring from Brandwatch, Meltwater, or Sprinklr costs $500 to $5,000 per month and bundles features most brands do not need. For "tell me when someone mentions my brand on Reddit," F5Bot does the job as well as any paid tool we have tested.
The signup walkthrough
End-to-end setup takes about 10 minutes.
- Go to f5bot.com and click "Sign Up."
- Enter a shared team inbox or an address that forwards into a Slack channel, not a personal email.
- Confirm the verification email.
- Paste your keyword list in, one per line. Capitalization does not matter.
- Save. The first alerts should start arriving within an hour.
There is no billing step. The service is free for the full 200-keyword limit.
Keyword strategy: what to watch
The 200-keyword limit sounds generous but is easy to exhaust. The categories we cover for every client:
- Brand name variants. The canonical name, common misspellings, and any historical name changes.
- Product names. Each distinct product or feature. For SaaS that is usually 3 to 10. For DTC it is every SKU worth monitoring.
- Founder and executive names. Catches trade-press stories before they spread.
- Competitor names. Comparisons between you and a competitor often show up in competitor threads first.
- Category terms. Generic terms like "password manager" or "task management app" so you catch category-level conversations.
- Domain variants. Your website plus any subdomain that might be shared (support., docs., status.).
For a typical B2B SaaS client, that comes out to 40 to 80 keywords, with plenty of headroom. For a multi-SKU DTC brand you might hit the ceiling, at which point you prioritize the SKUs that sell.
Slack integration and triage
Alert volume scales with keyword list and brand reach: small brands get 5 to 20 per day, large brands several hundred. Forward alerts to a shared inbox or directly into a Slack channel, never a personal email. The Slack pattern is the one we standardize across clients, and F5Bot is the single most common alert source feeding that channel (the full pattern is in our Slack back-office post).
Two routing options:
- Slack's email-to-channel feature. Click the channel name, go to "Integrations," and generate a unique email address. Point F5Bot at that address. Zero-config and the one we use most often.
- A Zapier or Make flow that parses the F5Bot emails and posts structured Slack messages with title, author, subreddit, and a clickable link. Marginally nicer, but it costs a task per alert.
Comparison to paid alternatives
Brandwatch, Meltwater, Sprout Social, and Conbersa are excellent for brands that need sentiment scoring at scale, multi-platform coverage across Twitter, TikTok, and podcasts, or historical search across months of data. Pay for those if your use case needs them. If your use case is "tell me when my brand is mentioned on Reddit," F5Bot is sufficient and free. We have run both in parallel and paid tools catch almost nothing F5Bot misses in the Reddit context.
Conclusion
F5Bot is the free brand monitoring backbone we deploy for every branded subreddit engagement. Sign up at f5bot.com, load 40 to 80 keywords covering brand variants, products, executives, competitors, category terms, and domains. Forward alerts into a Slack channel. Triage them as part of the Slack back-office workflow. The total setup time is under 30 minutes, the monthly cost is zero dollars, and the coverage is good enough for the overwhelming majority of brand use cases on Reddit.
How Soar saves you time and money
F5Bot is the free monitoring backbone we deploy on day one of every branded subreddit engagement. It replaces a $500 to $5,000 per month enterprise listening tool for the Reddit-specific alerting use case. Over a year, that is $6,000 to $60,000 that stays in the client's pocket, with equal or better alert quality for this narrow job.
A solo team setting this up from scratch usually spends 8 to 15 hours on keyword strategy, Slack wiring, and triage workflow before they have a working system. We ship all of that in under an hour because the keyword categories, email routing, and tagging scheme are reused across every engagement. If you want F5Bot wired into a full Slack back-office as part of a launch, our subreddit building and management service includes it by default.
