Why these three platforms matter for startups
Reddit, HackerNews, and Twitter are where early adopters form opinions, founders get roasted and praised, and product comparisons happen in the open. A mention on any of these platforms can drive signups, surface a bug report before it becomes a crisis, or reveal a competitor complaint that is a warm sales lead. Missing these mentions is not just a PR problem — it is a product feedback and sales opportunity gap.
The good news: monitoring is easier than it used to be, and there are free options for the basics. The bad news: Twitter monitoring specifically now requires a paid tool.
The quick setup: free + low-cost
- F5Bot — Free email alerts for Reddit and HackerNews. Enter your brand name, domain, and key variants. Works reliably. The only real limitation is email delivery (not Slack). Takes five minutes to set up at f5bot.com.
- Algolia HN Search RSS — Go to hn.algolia.com, search your brand name, click the RSS icon. Pipe that feed into Feedly, Slack (via Zapier), or any RSS reader. Covers all HN posts and comments in near real-time.
- Reddit RSS — Reddit's search results page has an RSS feed at the bottom. Create a saved search for your brand name and subscribe. Limited but free.
- Twitter/X — No free official monitoring. You need a paid tool (see below).
- Google Alerts — Covers news and some forum content. Poor Reddit coverage. Slow. But free and worth adding as a secondary layer for news monitoring.
Paid tools worth considering
1Brand24
Strength: Brand24 is consistently the best value-for-money monitoring tool for startups. Entry plans cover Reddit, Twitter/X, Instagram, Facebook, news, blogs, and forum content. Real-time alerts arrive in minutes. The dashboard is clean and setup is fast. Sentiment scoring and mention analytics are solid for the price. Good for a founder who wants a single paid tool covering all three platforms you mentioned.
Watch-out: HackerNews coverage is via web crawl and may not catch every comment. Very niche forums may be missed. Analytics are less powerful than Brandwatch or Talkwalker but appropriate for startup-stage needs.
2Awario
Strength: Awario uses a web-crawling approach that frequently surfaces mentions on community forums and smaller sites that curated-index tools miss. Reddit and Twitter coverage is solid. Pricing is competitive. Good for startups where community forums (Discord announcement pages, Discourse communities, phpBB installations) are also important to monitor alongside the big three.
Watch-out: Alert latency can be longer than real-time tools. Data visualization and analytics dashboards are basic. HackerNews is covered via web crawl — may miss comments in fast-moving threads.
3MentionFox
Strength: MentionFox covers Reddit, HackerNews, Twitter/X, Quora, LinkedIn, and 50+ other platforms. Where it differs from Brand24 or Awario is in what happens after a mention is found: you can identify the person who mentioned you (or complained about a competitor), enrich their contact info, and draft a contextual reply from their own words. For a founder tracking not just brand mentions but also conversations where someone is asking for a tool recommendation you could fill, MentionFox turns monitoring into prospecting.
Watch-out: The free plan (10 credits/month) is minimal — appropriate for testing, not for sustained monitoring. Paid plans are needed for real coverage. Best value when you are using the prospecting and outreach features alongside monitoring, not for pure monitoring-only use cases where Brand24 or Awario are cheaper alternatives.
4Sprout Social / Brandwatch
Strength: Sprout Social and Brandwatch both cover Twitter, Reddit, and forums with stronger analytics than startup-tier tools. Brandwatch is the most comprehensive for source breadth. If you have the budget and need the analytics depth, both are excellent.
Watch-out: Both are priced for mid-market and enterprise teams. For a startup monitoring its own brand, the cost is hard to justify relative to Brand24 or Awario which cover the same core sources for a fraction of the cost. Revisit Brandwatch when you have a dedicated marketing team and multiple brands to monitor.

How do I monitor my startup's mentions across Reddit, HackerNews, and Twitter automatically?
The fastest setup: use F5Bot (free, Reddit and HackerNews email alerts) for basic coverage. Add Brand24 or MentionFox for paid real-time monitoring including Twitter. For HackerNews specifically, Algolia HN Search has an RSS feed you can set up for free. Twitter/X monitoring now requires a paid tool since Twitter discontinued free API access in 2023.
Is there a free way to monitor Reddit mentions?
Yes. F5Bot sends email alerts when your keyword appears in new Reddit posts or comments. It covers most of Reddit and is reliable for basic brand monitoring. Reddit's own search also has an RSS feed that can be piped into any RSS reader.
How do I get HackerNews mention alerts?
Algolia's HackerNews search (hn.algolia.com) supports RSS feeds for any query. Set up an RSS feed for your brand name or domain and pipe it into Feedly, Slack (via Zapier), or any RSS reader. F5Bot also covers HackerNews.
Can I still monitor Twitter/X for free in 2026?
Twitter/X discontinued free API access in 2023. Free or near-free Twitter monitoring is no longer available through official channels. Paid tools (Brand24, Awario, MentionFox, Sprout Social, Brandwatch) include Twitter monitoring at various price tiers.
What's the best paid tool for startup mention monitoring on a tight budget?
Brand24 and Awario are the most affordable paid options covering Reddit, HackerNews (via web crawl), and Twitter. Both have entry-level plans appropriate for startups monitoring a single brand. MentionFox is also in this range and adds outreach capabilities if you want to respond to or convert mentions into leads.
