The best social listening tool is the one that finds useful posts on the sources your customers use and gives each post a clear next step.
B2B SaaS products often need Reddit, X, LinkedIn, YouTube, Hacker News, GitHub, Slack communities, and industry forums. Source coverage is only the first check. Filtering, alerts, ownership, reports, API access, and price decide whether your team will use the product each week.
I compared seven current tools with those jobs in mind. Prices and public plan limits were checked on October 9, 2026. Product limits can change, so confirm them before you buy.

| Octolens | Broad source coverage for growing SaaS | $199/month or $159/month billed yearly | 15+ sources with API, webhooks, and MCP | Higher entry price |

| Awario | Classic social listening at a lower price | $49/month or $29/month billed yearly | Boolean search and 30,000 new mentions on Starter | API requires Enterprise |
Use this table as a shortlist. Run the same five to ten keywords in two products before you decide.
Detailed comparison and reviews
1. Mentionkit: best for B2B SaaS brand monitoring and action
Mentionkit tracks brand, keyword, and competitor mentions across Reddit, X, LinkedIn, YouTube, GitHub, Slack, forums, and other sources. AI filtering puts actionable mentions first. Users can review, assign, reply to, and report on mentions in one place.
The Base plan costs $49 per month. It includes 10 keywords, 10 trackers, one project, up to five seats as a soft limit, unlimited mentions, API access, MCP, webhooks, Slack alerts, and email alerts. The trial lasts 14 days.
Mentionkit fits founder-led products, marketing staff, and support staff that need one shared queue. It also helps find posts from people seeking a product, but lead discovery is a secondary use.
Pick Mentionkit when source coverage, useful filtering, and follow-up matter more than large media research dashboards. Pick another tool if you need advanced sentiment charts across millions of news and media items.
2. Octolens: best for broad SaaS source coverage
Octolens monitors more than 15 public sources and uses AI to filter mentions. Its product pages list Reddit, LinkedIn, X, YouTube, Hacker News, Bluesky, GitHub, Product Hunt, forums, and other sources.
The Pro plan costs $199 per month or $159 per month with yearly billing. It includes 10 keywords, 15,000 mentions per month, hourly checks, API access, webhooks, MCP, Slack, and email. Scale costs $599 per month or $499 per month with yearly billing and raises the limits to 40 keywords and 50,000 mentions. It also adds real-time checks and more web sources.
Octolens fits a SaaS business that wants wide source coverage and developer access. Its entry price is much higher than tools made for a small keyword list. Broad coverage also needs careful keyword settings, or the feed can contain weak matches.
3. Syften: best for detailed community alerts
Syften has a long focus on community monitoring. Its filters cover sites such as Reddit, Hacker News, Indie Hackers, and other public communities. Higher plans include API, webhooks, Slack, MCP, and AI filtering.
The Entry plan costs $29.95 per month. It includes three community filters, one web filter, 100 community results per day, five web results per day, and a seven-day archive. Standard costs $49.95 per month and includes 20 community filters, AI filtering, API access, and Slack. X costs an extra $40 per month and YouTube costs an extra $20 on Standard. Pro costs $119.95 per month and adds 100 filters, an unlimited archive, webhooks, and MCP. Syften offers a 14-day Pro trial.
Syften fits technical founders who know which communities and terms they need. Check the total price if X and YouTube matter, because add-ons can change the comparison.
4. KWatch: best low-cost cross-platform keyword monitor
KWatch monitors Reddit, Hacker News, X, YouTube, Facebook, and LinkedIn. It sends email, Slack, or webhook alerts and can apply AI sentiment analysis.
The free plan has two Reddit keyword alerts and two Hacker News alerts. Essential costs $19 per month and includes 20 Reddit alerts, 20 Hacker News alerts, two X alerts, two YouTube alerts, one Facebook alert, and one LinkedIn alert. Business costs $79 per month and raises those limits. It also adds API, webhooks, Slack, MCP, bulk keyword imports, and team management.
KWatch is a good way to test several sources on a small budget. Review per-source limits before you subscribe. Ten keywords do not mean ten keywords on every platform.
5. ForumScout: best for lead discovery
ForumScout scans Reddit, X, LinkedIn, YouTube, Instagram, Bluesky, Hacker News, Facebook, forums, news sites, and other web sources. Users paste a website, then ForumScout reads the product details, scans for matching posts, and gives each result an AI score and explanation.
Its public site lists a seven-day trial with no card, Google Sheets and webhook integrations on all plans, and new results every six hours to every hour based on plan. It also tracks brand and competitor names. Check the live checkout for current plan prices.
ForumScout is the most lead-focused product in this list. That helps sales work, but a brand team should test ownership, support routing, response records, and reports before using it as its main brand tracking tool.
6. Brand24: best for reports and broad media monitoring
Brand24 tracks social media, news, blogs, forums, reviews, podcasts, newsletters, and other web sources. It has sentiment analysis, reach data, dashboards, topic analysis, AI summaries, and reports.
The Individual plan costs $249 per month, or $199 per month with yearly billing. It includes three keywords, 2,000 mentions per month, one user, and updates every 12 hours. Team costs $349 per month, or $299 per month with yearly billing, and includes seven keywords, 10,000 mentions, unlimited users, and hourly updates.
Brand24 fits PR staff, agencies, and brands that need reports across media types. The entry price and update rate can be hard to justify for a small SaaS business that needs a few fast social alerts.
7. Awario: best lower-cost classic social listening dashboard
Awario tracks brand, competitor, and market terms with Boolean search, sentiment analysis, location filters, exports, and reports.
Starter costs $49 per month or $29 per month with yearly billing. It includes three topics, unlimited keywords inside each topic, 30,000 new mentions per month, 5,000 stored mentions per topic, and one user. Pro costs $149 per month or $89 per month with yearly billing and raises the limits to 15 topics, 300,000 monthly mentions, and 10 users. Awario’s help center states that API access requires Enterprise.
Awario fits a marketer who wants a familiar monitoring and analysis product without Brand24 pricing. Its topic model is useful when one subject needs many keyword variations. Test the source mix and stored-mention limits against your own work.
How to choose a social listening tool
Start with the result you need each week.
- List required sources. Mark each as required or optional. A large source count has no value if the product misses your main forum.
- Run the same keywords. Use your brand, domain, one misspelling, two competitors, and three specific market phrases.
- Count useful mentions. Record posts that led to support, feedback, a reply, a report, or a sales follow-up.
- Check false matches. Measure how many minutes you spend removing spam and unrelated posts.
- Test the full workflow. Assign a mention, draft a reply, mark it complete, and export or report the outcome.
- Compare real monthly cost. Include add-ons, keyword limits, mention limits, seats, and time spent reviewing weak results.
Choose by fit:
- Pick Mentionkit for B2B SaaS brand, keyword, and competitor monitoring with follow-up.
- Pick Octolens for broad SaaS source coverage and higher limits.
- Pick Syften for detailed community filters.
- Pick KWatch for a low-cost test across several social platforms.
- Pick ForumScout when lead discovery is the main job.
- Pick Brand24 for broad media reports and brand analysis.
- Pick Awario for a classic listening dashboard at a lower entry price.
Conclusion
Shortlist two tools that cover your required sources. Test them with the same terms for 7 to 14 days. Compare useful mentions, missed posts, weak matches, response work, and full monthly cost.
For a B2B SaaS product that needs actionable mentions and a clear shared workflow, start with Mentionkit. For media analysis or lead-first work, Brand24 or ForumScout can be a better fit.
