8 Best F5Bot Alternatives for Reddit Monitoring in 2026

F5Bot has been the default free way to watch Reddit since 2017. Add a keyword, and it emails you when that word shows up in a Reddit post or comment, on Hacker News or on Lobsters. For years that was all a founder needed.

The free version is more limited now. According to F5Bot's tiers page, the free plan is for personal use only, covers 5 keywords and 20 alerts a day, and sends alerts "within 2 hours." Common words are blocked on free accounts, and match history lasts 7 days. Faster alerts, filters, Slack and AI filtering are on paid plans.

If you've hit those limits, or you need more than Reddit and Hacker News, this guide compares eight alternatives with September 2026 pricing.

Quick answer: If you want to stay cheap and focused on Reddit and Hacker News, KWatch has a free plan and a $19/month tier that adds X, YouTube, Facebook and LinkedIn. Syften (from $29.95/month) is the step up for faster Reddit alerts, precise filters and more communities. Reddit Pro is free if Reddit is all you care about. If your problem is replying well rather than finding threads, Okara's Reddit Agent drafts replies for you to post.

How we compared: we checked each tool's pricing page and documentation in September 2026. Okara publishes this guide. Prices are in USD and change often, so confirm before you buy.

Quick comparison

What F5Bot costs now

Before you switch, it's worth knowing that F5Bot's paid plans may solve your problem:

Paid plans add exclude and require filters, full post text and alert grouping. Gold adds a Slack or Discord integration and two AI filters, which match posts from a plain-English description instead of exact keywords. AI filter usage beyond the first $10 a month is billed on top. If you only need a few more keywords and faster alerts, Silver at $9.99 is the cheapest fix on this page.

Why people look for F5Bot alternatives

• The free tier got tighter. Five keywords and a two-hour delay is fine for a hobby, not for catching a buying-intent thread while it's still active.
• Only three sources. F5Bot covers Reddit, Hacker News and Lobsters. Conversations on X, LinkedIn, forums, Slack communities and GitHub are invisible to it.
• Common words are blocked on free. If your brand is a dictionary word, the free tier won't track it.
• Alerts aren't the hard part. Many founders find the threads fine but struggle to reply in a way that fits each subreddit's rules.

The 8 best F5Bot alternatives

1. KWatch: the cheapest step up

Best for: Founders who want Reddit and Hacker News alerts plus a little X, YouTube and LinkedIn, on a small budget.

KWatch monitors keywords on Reddit, Hacker News, X, YouTube, Facebook (public groups) and LinkedIn, and sends alerts by email, Slack or webhook.

3. Reddit Pro: free, straight from Reddit

Best for: Businesses that only care about Reddit and want a free, official option.

Reddit Pro is Reddit's free toolkit for businesses. It lets you track keywords and phrases, such as your business, products and competitors, to see what people are saying about you on Reddit, and it helps you set up a business profile.

4. Octolens: AI-filtered monitoring for dev and B2B brands

Best for: Developer-tool and B2B SaaS teams who want every mention scored for relevance across many platforms.

Octolens monitors Reddit, X, LinkedIn, Hacker News, GitHub, YouTube, Bluesky, TikTok, DEV and Stack Overflow, and its Scale plan adds podcasts, newsletters, news, the web and review sites. AI scores each mention for relevance, tags it and analyzes sentiment. Every plan includes unlimited team seats, Slack and email alerts, an API, webhooks and an MCP server.

Pros:

• AI relevance filtering on every mention
• Covers LinkedIn and GitHub, which F5Bot doesn't
• Unlimited seats

Cons:

• Far more expensive than F5Bot
• Pro refreshes hourly; real-time needs Scale
• Pricing is based on mentions, with overage billed per mention

5. Awario: cheap social listening with web coverage

Best for: Small brands that want Reddit plus broader social and web mentions without an enterprise price.

Awario tracks mentions across Reddit, X, Facebook, Instagram, YouTube, Vimeo, news and the web. Each "topic" can hold unlimited keywords, and the Starter plan finds up to 30,000 new mentions a month across 3 topics.

7. Google Alerts: a free backup, not a replacement

Best for: Catching web and news mentions at no cost, alongside a real Reddit monitor.

Google Alerts emails you when new results for a topic show up in Google Search. You can choose how often you get emails, which types of sites to include, language and region. Because it relies on Google's index, Reddit and Hacker News threads only appear after Google has crawled them, which can be too late to join the conversation.

Pros:

• Free
• Good for news, blogs and web pages
• Takes a minute to set up

Cons:

• Not real-time for Reddit or Hacker News
• No subreddit filters, Slack or API
• Results can be noisy for common terms

Price: Free.

8. Okara: when finding threads isn't the problem

Best for: Founders who get plenty of alerts but don't have time to write good replies.

Every tool above tells you where a conversation is. Okara's Reddit Agent, included in AI CMO Pro ($249/month), monitors your keywords, surfaces high-intent threads every day, summarizes each subreddit's rules and culture, and drafts a reply. You review it and post from your own Reddit account. Nothing is posted automatically.

Be clear about the limits. Okara covers Reddit only, not Hacker News or Lobsters, and it isn't a general alert tool with feeds, webhooks or per-keyword email alerts. It's also far more than F5Bot costs, because the same plan includes SEO, content, LinkedIn and other agents.

Pros:

• Surfaces threads worth replying to, not every keyword match
• Subreddit rule summaries before you post
• Reply drafts you edit and post yourself

Cons:

• Reddit only
• No alert feeds, webhooks or API
• Expensive if monitoring is all you need

Price: Free plan (website analysis and strategy only); AI CMO Pro $249/mo ($208/mo billed annually) includes the Reddit Agent. See Okara pricing.

Keywords that find buying intent

Whichever tool you choose, what you track matters more than the tool. Brand names catch mentions. These patterns catch people who are ready to buy:

"alternative to [competitor]"
"[competitor] alternative"
"[competitor]" "too expensive"
"looking for a" [category] tool
"recommend" [category]
"switching from [competitor]"

On F5Bot, you can limit any of these to specific subreddits with the only-url flag, for example only-url=/r/SaaS. On Syften, the equivalent is site: reddit.com/r/SaaS.
