The four free options

F5Bot

F5Bot monitors Reddit and Hacker News for keywords and emails you when they appear. It's free, it has no usage limits worth worrying about, and it does what it says.

What it does well: keyword coverage across all of Reddit, fast delivery, no cost, no account setup friction beyond an email address.

Where it breaks: it's a notification pipe, not a workflow. Every match generates an email. There's no sorting, no filtering beyond exact keyword matching, no way to mark something handled, and no shared view for a team. If your brand name is a common word, your inbox becomes unusable within a week.

For a solo founder with a distinctive product name and low mention volume, F5Bot is often genuinely sufficient. We say the same on our F5Bot comparison page.

Reddit saved searches

Reddit's own search supports operators and you can bookmark result URLs:

What it does well: free, no third party involved, full control over query syntax, works retroactively across history.

Where it breaks: it's pull, not push. Nobody gets notified — someone has to remember to open the bookmarks. In practice, this decays within about three weeks. Reddit search relevance is also inconsistent, particularly for recent posts, which matters because recent posts are the ones worth replying to.

Google Alerts

Set up an alert for site:reddit.com "your brand" and Google emails you when it indexes a matching page.

What it does well: free, catches mentions outside Reddit too, zero setup.

Where it breaks: latency. Google Alerts fires when Google indexes a page, which can be hours or days after posting. For brand reputation archaeology that's fine. For replying to a live thread, it's structurally too late — most Reddit threads have settled their top comments long before the alert arrives.

Reddit RSS feeds

Almost every Reddit page has an RSS equivalent — append .rss to a subreddit URL or a search URL and pipe it into a reader or a Zapier/Make workflow.

What it does well: free, near-real-time, scriptable, and it composes with other tools.

Where it breaks: you're now maintaining infrastructure. Feeds break silently. Deduplication is your problem. Filtering is your problem. It's a good option if someone on your team enjoys this kind of plumbing, and a liability if that person leaves.

Side by side

ㅤ	F5Bot	Saved searches	Google Alerts	RSS
Cost	Free	Free	Free	Free
Push notification	Yes	No	Yes	Depends on setup
Latency	Minutes	Manual	Hours–days	Minutes
Noise filtering	Exact match only	Query operators	Minimal	Whatever you build
Team visibility	No	No	No	No
Mark as handled	No	No	No	No
Competitor tracking	Same inbox	Separate bookmarks	Separate alert	Separate feed
Maintenance burden	None	Low	None	Ongoing

Look at rows five and six. Every free option shares the same two gaps: no shared team view, and no way to record that something was handled. That's not a coincidence — those are workflow features, and free tools are notification tools.

The three failure points

Free monitoring breaks in predictable ways.

1. Volume overwhelms the inbox.

Free tools match keywords exactly, with no relevance weighting. If your brand name is a real word, or you're tracking category terms like "social listening" alongside your brand, matches arrive faster than anyone reads them. The failure isn't missing mentions — it's having so many that nobody opens the folder.

2. Nobody owns the response.

Alerts land in one person's inbox. When that person is busy, travelling, or moves teams, the whole practice stops. There's no queue, no assignment, no visibility into whether a thread got answered. Teams routinely discover months later that a high-intent thread sat unanswered because it arrived during someone's vacation.

3. Timing gets missed.

The window on a Reddit thread is short — the top comments are typically settled within the first several hours. Free tools tell you a mention exists; they don't tell you it's the one worth dropping everything for. So either you check every alert immediately (unsustainable) or you batch them (too late).

When free is genuinely the right answer

Stay free if most of these are true:

One person handles all replies

Your brand name is distinctive enough to avoid false matches

You're getting fewer than roughly 20 mentions a week

You're not tracking competitor keywords

You don't need to prove the work to anyone

Nobody's asking about ROI

That describes a lot of early-stage products, and there's no reason to pay before those conditions change. Set up F5Bot, read our Reddit monitoring guide for keyword strategy, and revisit in a quarter.

When free starts costing more than it saves

The math flips when:

More than one person replies.

The moment two people share responsibility, you need a shared queue or you'll get duplicate replies in the same thread — which, as covered in Reddit's self-promotion rules, reads as coordinated manipulation to moderators.

You're tracking competitors.

Competitor mentions need to be separate from brand mentions, because they're a different workflow with different urgency. One inbox for both means neither gets worked properly.

Volume passes roughly 30 mentions a week.

Past that, unsorted alerts stop being read.

Someone asks what it's producing.

Free tools generate no record. You can't answer "how many threads did we reply to last month, and what came of it" without one.

Reply drafting is the bottleneck.

Finding the thread takes seconds. Writing a good reply from a blank box takes fifteen minutes, and that's where the practice actually dies.

That last point is the one teams underestimate. The scarce resource isn't detection. It's the activation energy of writing something thoughtful, repeatedly, on a Tuesday afternoon.

A reasonable progression

You don't have to pick a side on day one:

Month 1 — F5Bot only.

Learn what your actual mention volume is and which keywords produce signal versus noise. Costs nothing and teaches you what you'd be buying.

Month 2 — Add structure.

Keep F5Bot, but log every reply in a shared sheet: thread URL, date, who replied, what happened. This is manual and slightly annoying, and it will tell you more about whether Reddit works for you than any tool will.

Month 3 — Decide with data.

You now know your volume, which subreddits produce results, and how much time this takes. If the sheet shows a real return and the manual overhead is the constraint, that's when a paid tool pays for itself. If the sheet shows nothing, you've saved yourself a subscription.

For a fuller comparison of what's available when you get there, see our roundup of the best Reddit monitoring tools. And before you buy anything, set up the attribution described in brand monitoring ROI — otherwise month three's decision is a guess either way.

Frequently asked questions

Is F5Bot still maintained and reliable? It has run as a free service for years and remains one of the more dependable free options for Reddit and Hacker News keyword alerts. As with any free single-maintainer service, don't build a business-critical process on it without a fallback.

Can I monitor competitors for free? Yes — add their brand names as keywords in F5Bot or a saved search. The limitation is separation: everything arrives in the same inbox, so competitor threads compete with your own brand mentions for attention rather than being worked as a distinct queue.

Does Reddit's API affect free monitoring tools? Reddit's API pricing changes affected many third-party applications. Tools that rely on official API access have to account for those costs, which is part of why free tools tend to be narrow in scope. It's worth checking any free tool's current status rather than assuming last year's setup still works.

What about monitoring X (Twitter) for free? Considerably harder. X's API access changes removed most of the free tooling that used to exist. Free X monitoring today largely means manual search, which doesn't scale. Our guide on tracking brand mentions on X covers the current options.

How many keywords should I track when starting out? Start with three to five: your brand name, one or two category terms, and your closest competitor. Add gradually. Teams that start with thirty keywords abandon monitoring within a month because the noise makes the whole thing feel useless.

Will a paid tool find mentions that free tools miss? Sometimes, but that's rarely the real difference. Both catch the same public posts. What paid tools add is sorting, separation, team visibility, reply drafting, and a record of what was done. If detection is your only problem, free is fine.

The takeaway

Free Reddit monitoring works, and it works better than most vendors will admit. If you're one person with a distinctive product name and modest volume, F5Bot plus a shared spreadsheet will serve you well for months.

What free tools can't do is turn a notification into a team habit. That's the actual line — not features, not coverage.

So the useful question isn't "is this tool good enough?" It's: when the alerts stop getting read, what happens next? If the answer is "the practice quietly ends," that's your signal, whatever tier you're on.

SignalMelo puts Reddit and X mentions in one shared inbox, keeps competitor mentions in a separate queue, and drafts replies your team edits before posting. Free setup scan, no credit card.
