What is the best free Reddit monitoring tool?

F5Bot. It watches Reddit posts and comments plus Hacker News and Lobsters and emails you when your keywords appear, at no cost. Google Alerts is a useful second net across the rest of the web, but it lags by days and largely misses comments. Neither one gives you searchable history, sentiment, or team routing.

Can Google Alerts monitor Reddit?

Partially. Google Alerts fires when a page containing your keyword enters Google's index, so it catches some Reddit submissions, usually days after they were posted. It does not reliably catch comments, which is where most Reddit buying signal lives, and it offers no subreddit filtering. It is a good free backstop and a poor primary tool.

How is Reddit monitoring different from Reddit social listening?

Monitoring is alerting: a keyword matched, here is the thread, go look. Social listening is analysis: sentiment over time, which themes are growing, share of voice against competitors. Most teams need monitoring first, because a real-time alert on a buying-intent thread is worth more than a monthly sentiment chart.

Do Reddit monitoring tools need my Reddit account?

Alert-only tools do not. They read public Reddit content and never touch your account. Tools that also help you reply usually do connect to it, and that is where to read the fine print carefully: anything that posts without your review risks a subreddit ban or a sitewide shadowban on the account you depend on.

Is it worth paying for Reddit monitoring when F5Bot is free?

Only if you have a job free tools cannot do. Paying makes sense when you need subreddit-level targeting to control noise, intent scoring to prioritize which threads to answer, searchable mention history, routing to a team, or measurement of whether your Reddit activity is changing your visibility in AI answers.

12 Best Reddit Monitoring Tools in 2026 (Free and Paid)

Short answer: for free Reddit keyword alerts, use F5Bot. If Reddit is one channel in a broader listening program, use Brand24 or Awario. If Reddit is a channel you actually sell through, and you care whether those threads shape what ChatGPT and Perplexity tell buyers about your category, use ReddGrow. Most teams need one of those three, not all twelve.

This list runs to twelve because “Reddit monitoring tool” describes three different products shelved together. Mention alert tools tell you when your keyword appears. Buying-intent tools tell you which of those threads is worth answering. AI-visibility tools measure whether Reddit conversations in your category show up in AI-generated answers. Buying the wrong type is the most expensive mistake here, so the table below sorts by type first.

Prices were verified against vendor pricing pages on September 2, 2026. Where a vendor does not publish a number, we say so rather than guessing.

1. ReddGrow

Best for: teams treating Reddit as an acquisition channel and measuring the effect on AI answers.

ReddGrow is Reddit-only by design. It scans Reddit continuously for your brand, competitor, and category keywords, then scores every thread on purchase intent, audience size, sentiment, and AI citation likelihood, so you triage instead of reading everything. Alerts arrive in Slack, email, or in-app with full thread context. The part no other tool here attempts is the second half: it tracks whether ChatGPT, Perplexity, Google AI, and Claude are citing your category, and ties movement in that number back to specific threads. Replies are drafted in-app and published through your own account only after you approve them.

Tradeoff: it does not monitor X, LinkedIn, news, or review sites. If you need a single dashboard for every channel, this is the wrong shape of tool.

Price: Starter is $99/month month-to-month, or $79/month billed annually. Growth is $199/month ($159 annual) and Pro is $399/month ($319 annual). All plans include a 14-day free trial. A free visibility check is available at am-i-on-reddit.

2. F5Bot

Best for: free keyword alerts when one person will read all of them.

F5Bot watches Reddit posts and comments plus Hacker News and Lobsters, and emails you when your keywords appear. It has been the default free option for years for good reason: it is fast, it covers comments, and setup takes five minutes. There is no dashboard, no searchable history, no sentiment, and no way to hand an alert to a colleague. For a solo founder tracking a brand name and two competitors, that is not a real limitation.

Tradeoff: email-only delivery and no team workflow. Volume becomes unmanageable the moment you add a broad category keyword.

Price: Free forever on the free plan, capped at 5 keywords for personal use with alerts inside two hours. Paid plans start at $9.99/month, or $109/year.

3. Syften

Best for: precise filters across Reddit and other communities, delivered fast.

Syften is built around query precision rather than dashboards. You can combine phrases, exclusions, domains, usernames, and subreddit restrictions, which matters in B2B where people paste a docs URL or a GitHub repo instead of a clean product name. Matches route to Slack, email, RSS, webhooks, or an API, and agencies can tag filters per client. It covers Reddit alongside Hacker News, forums, and other communities.

Tradeoff: no sentiment analysis, no engagement workflow, and no reporting layer. It finds conversations well and does nothing with them afterward.

Price: $29.95/month on the Entry plan. No free tier, but there is a 14-day trial of Pro with no card required.

4. Octolens

Best for: B2B software teams who want intent, not mention counts.

Octolens monitors Reddit alongside other channels specifically for buying signals, using an AI layer so “someone asking for a tool like yours” outranks “someone using your brand name as a verb.” Their analysis of 522 million Reddit mentions across 300,000-plus monitored brands found roughly 23% of B2B-relevant Reddit discussion shows active buying intent, a fair summary of the gap between mention volume and useful volume.

Tradeoff: priced for funded B2B teams rather than solo founders, and Reddit is one source among several rather than the primary focus.

Price: $199/month month-to-month, or $159/month billed annually, on the Pro plan. No free tier; 7-day trial.

5. RedNudge

Best for: a lightweight Reddit-only intent feed at a small-team price.

RedNudge watches Reddit for posts and comments matching your product’s problem space and surfaces the ones worth replying to, with AI-suggested reply angles. It is a narrower product than the platforms above and priced accordingly, which makes it a reasonable first paid step once F5Bot’s email volume stops being readable.

Tradeoff: small vendor, thinner track record, and no AI visibility measurement. Verify current coverage before committing to an annual plan.

Price: $7/month on the Starter plan. No free tier, 7-day trial with no card required.

6. Brand24

Best for: Reddit as one line in a monthly social listening report.

Brand24 covers Reddit alongside X, news, blogs, review sites, and podcasts, with sentiment analysis, share-of-voice charts, and exportable reporting a marketing lead can put in front of a CMO. It is a genuinely good general listening platform and the right answer if Reddit is one of many channels you are accountable for.

Tradeoff: Reddit gets no special treatment. No subreddit-level targeting, no comment-thread context, no engagement workflow, and no AI citation tracking. We compare it in detail on our Brand24 alternatives page.

Price: $249/month month-to-month, or $199/month billed annually, on the Individual plan. No free tier; 14-day trial.

7. Awario

Best for: Boolean-style social listening when the Brand24 tier is too expensive.

Awario is the budget end of general social listening. You get Boolean query building, sentiment, location and language filters, and a shared inbox, across Reddit and the usual social and web sources. For teams who want real listening features without an enterprise line item, it is the most reasonable entry point in this group.

Tradeoff: less polished reporting than Brand24, and the same structural limitation: Reddit is a source in a list, not a first-class channel with subreddit logic.

Price: $49/month month-to-month, or $29/month billed annually, on the Starter plan. No free tier.

8. Mention

Best for: larger teams combining monitoring with social publishing.

Mention is the most enterprise-shaped product here, pairing web and social monitoring with publishing, approval workflows, and competitive analysis. If your organisation needs role-based access, audit trails, and a vendor with a support contract, it clears bars the smaller tools on this list do not attempt to.

Tradeoff: the entry point is a sales conversation rather than a signup form, and pricing reflects a suite rather than a Reddit tool. Overkill unless you need the publishing side.

Price: Pricing on request. Mention no longer publishes a figure; its page lists one demo-gated Company plan.

9. Linkeddit

Best for: finding Reddit threads where someone is asking for what you sell.

Linkeddit is squarely a lead-finding tool rather than a brand monitor. You describe your product, and it surfaces Reddit posts from people describing the problem it solves, with AI-drafted reply suggestions. That framing is genuinely different from keyword alerting: it catches high-value threads that never mention your brand at all.

Tradeoff: it is not a brand monitor. If someone complains about you by name in a thread that has nothing to do with your category keywords, this is not the tool that catches it.

Price: $49/month on the Pro plan billed monthly, or $450 once for lifetime access. No free plan.

10. RedReach

Best for: Reddit lead discovery with reply assistance for small teams.

RedReach occupies similar ground to Linkeddit: intent-matched Reddit threads plus AI-generated reply drafts, aimed at founders doing their own outreach. The useful distinction between tools in this bracket is usually whether they surface comment-level matches or only post titles, so check that before subscribing.

Tradeoff: early-stage product, and the automated-reply framing deserves caution. Anything that posts without your review risks the subreddit access you bought the tool to get.

Price: $19/month on the Startup plan. No free tier, though a $12 one-time three-day pass is available.

11. Google Alerts

Best for: a free, zero-effort backstop across the whole web.

Google Alerts emails you when a page containing your keyword enters Google’s index, which includes some Reddit threads along with news, blogs, and everything else. It costs nothing, takes two minutes, and catches things a Reddit-only tool never sees. Every team should have one running regardless of what else they pay for.

Tradeoff: it is not a Reddit tool. Alerts lag by days, comments are largely missed, and there is no subreddit filtering. Treat it as a safety net, never as coverage.

Price: Free.

12. Devi

Best for: watching Reddit alongside Facebook Groups, LinkedIn, and Quora on one bill.

Devi prices per platform rather than per tier, which is unusual and genuinely useful. Reddit monitoring is $9 a month on its own, and you add Facebook Groups, LinkedIn, X, Quora, Nextdoor, or others only if you need them. It matches keywords against buying intent and drafts replies, making it the cheapest way to cover several community platforms at once.

Tradeoff: the cost climbs fast once you add platforms, and Facebook Groups is the expensive module the pricing is built around. There is no free trial either; the ten-day trial costs $1.

Price: $9/month for the Reddit module, or $90/year.

How to choose a Reddit monitoring tool

Start with the job you need done, because the three categories rarely substitute for each other.

If you only need to know when your name comes up, a free alert tool covers it. F5Bot and Google Alerts cost nothing and take ten minutes to configure. The honest ceiling is that neither gives you a dashboard, searchable history, sentiment, or any way to route a mention to a teammate. For a solo founder watching one brand name, that ceiling is fine.

If Reddit is one of many channels you report on, a general listening platform beats a Reddit specialist. Brand24, Awario, and Mention produce the sentiment charts and share-of-voice reports a marketing lead expects in a monthly deck. The tradeoff is depth: Reddit is one source among twenty, so you rarely get subreddit-level targeting or comment-thread context.

If Reddit is a real acquisition channel, you need buying-intent scoring rather than mention counting. A brand alert fires when someone already knows you exist. An intent alert fires when someone in r/devops asks “what are people using for this” and has never heard of you, which is the more valuable thread and the one a keyword matcher will not flag.

A few practical checks before you pay for anything:

Does it monitor comments, not just post titles? Most buying intent on Reddit lives several replies deep. A tool that only indexes submissions misses the majority of it.
Can you include and exclude specific subreddits? Without this, a common category keyword produces unusable volume within a week. If you are not sure which communities belong on the list, our free subreddit finder searches over three million of them by keyword.
How fast is the alert? A recommendation thread is worth replying to for roughly a day. A digest that arrives 48 hours later is a research artifact, not an engagement tool.
Where does the alert land? If a mention never reaches the person who can act on it, the tool is not working regardless of how good the matching is.
Is the vendor still selling? This category churns. GummySearch, for years the default Reddit research tool, stopped accepting new signups, upgrades, and renewals after November 30, 2025, with data deletion scheduled for December 1, 2026. If you are migrating, we wrote up the GummySearch alternatives in detail.

One thing worth saying plainly: none of these tools post for you safely on autopilot. Reddit moderators are unusually good at spotting automated brand behavior, and a flagged account loses access to the exact subreddits you bought the tool to reach. Use monitoring to find the conversation faster, and keep the reply human.

Why AI answers make Reddit monitoring matter more

This category got crowded in 2026 because Reddit threads now feed the answers buyers get from AI assistants. An unmonitored Reddit conversation is no longer just that; it is source material for the recommendation a buyer receives instead of visiting your site.

The evidence is consistent across independent trackers. 5W’s “State of AI Citations 2026” report, synthesizing nine datasets covering over 680 million tracked citations, found Wikipedia (13.15%) and Reddit (11.97%) together account for more than a quarter of all ChatGPT citations in the US, ahead of the Wall Street Journal, New York Times, and Bloomberg combined. Semrush’s cross-platform study of 230,000-plus prompts and over 100 million citations independently landed on Reddit, LinkedIn, and Wikipedia as the three most-cited domains. For B2B the effect is sharper still: Foundation Inc.’s analysis of 8,566 B2B SaaS keywords found Reddit outranking the vendor’s own website on 49.2% of queries, rising to 67.2% on high-CPC commercial-intent terms.

The caveat matters as much as the headline. Reddit’s citation share is volatile: Peec AI’s tracking documented ChatGPT’s share of Reddit-sourced citations swinging from roughly 60% down to about 10% within weeks in late 2025 as OpenAI adjusted retrieval, and trackers rank Reddit anywhere from first to fourth depending on methodology. That volatility argues for continuous measurement, not for dismissing the channel. The full set of sourced numbers, including the ones we could not verify, is in our Reddit statistics for 2026.

So monitoring now has two jobs: know what is being said, which every tool here attempts, and know whether those threads are surfacing in the answers ChatGPT and Perplexity give buyers in your category, which almost none of them do. Measure only mentions and you are measuring the input while guessing at the output.

ReddGrow monitors Reddit for brand, competitor, and category conversations, scores threads by buying intent, and tracks whether your brand is being cited by ChatGPT, Perplexity, Google AI, and Claude. Start with a free check at am-i-on-reddit, or see the full Reddit brand monitoring workflow.
