Looking for an Octolens Alternative? Compare KWatch.io for Real-Time Social Listening

What each product is for

Octolens positions itself as B2B social listening with AI relevance filtering, delivery to Slack/email/webhooks, and coverage across community platforms. Public pricing (as of this writing, billed annually): Pro at $159/month (10 keywords, 15,000 mentions, hourly refresh) and Scale at $499/month (higher limits, real-time). API, webhooks, and an MCP server are on every plan. Sources they list include Reddit, X, Linkedin, Hacker News, Youtube, plus GitHub, Stack Overflow, Bluesky, podcasts, newsletters, TikTok, news, and more. They do not list Facebook or Instagram.

KWatch.io is keyword social listening with real-time alerts (per-second refresh) across Reddit, Hacker News, X, Linkedin, Facebook, and Youtube. Email on every plan. Slack and API webhooks start on Business. AI sentiment on Essential and above. Conversation tracking on Reddit and Hacker News. Free plan exists (Reddit 2 + Hacker News 2 keyword alerts only).

If you need to watch what a named Linkedin or X account posts, likes, or comments on, that is a different job: MultiFollow. Neither Octolens nor KWatch replaces that.

Pricing: the part most comparison pages skip

KWatch Essential ($19/mo) keyword alerts: Reddit 20, Hacker News 20, X 2, Youtube 2, Facebook 1, Linkedin 1, plus 2 tracked conversations on Reddit and 2 on Hacker News. Filtering, saved results, AI sentiment. No Slack, no API webhooks, no bulk CSV import, no teams.

KWatch Business ($79/mo): Reddit 100, Hacker News 100, X 10, Youtube 10, Facebook 5, Linkedin 5, Reddit 10 + Hacker News 10 tracked conversations. Slack, API webhooks, bulk import, teams.

KWatch Enterprise ($199/mo): Reddit 500, Hacker News 500, X 50, Youtube 50, Facebook 25, Linkedin 25, Reddit 50 + Hacker News 50 tracked conversations. Advanced support.

Plans are prorated. You can stop anytime.

So: if your bar is 10 keywords, Slack + API on day one, and you also care about GitHub/podcasts, Octolens Pro is built for that, at roughly 8x Essential. If your bar is real-time Reddit/HN/Linkedin/X/Facebook alerts without a mention meter, KWatch is usually cheaper for the same core job.

Platforms: where the products actually diverge

Octolens has, KWatch does not (today): GitHub, Stack Overflow, Bluesky, podcasts, newsletters, TikTok, news/web crawls, DEV.to, and similar community sources. If those are where your buyers talk, do not force KWatch into that gap.

KWatch has, Octolens does not (from their public pricing/source list): Facebook posts, including public Facebook groups (not private groups, and not Facebook comments). Linkedin posts that are not sitting in Google. X posts and comments that are not publicly indexed. Conversation tracking on a specific Reddit or Hacker News thread so every new comment alerts you even when the comment does not contain your keyword.

Shared ground: Reddit, X, Linkedin, Hacker News, Youtube (on KWatch: title and description only; spoken audio in a video does not fire).

Neither monitors Instagram for keyword listening in the way most teams expect. KWatch also does not monitor TikTok, GitHub, Stack Overflow, Bluesky, podcasts, or newsletters.

Honest Linkedin/Facebook limits on our side: we monitor posts, not comments. Linkedin, Facebook, Youtube, and X are paid-plan sources.

Speed and delivery

Octolens Pro refreshes hourly. Scale is real-time. KWatch refresh is per second on the sources we cover; you should expect an alert within a couple of seconds, up to about a minute if things are congested.

• Octolens: email, Slack, webhooks, full API, MCP on every paid plan; AI relevance scoring (high/medium/low) so you can mute low-relevance noise.
• KWatch: email always; Slack and API webhooks from Business up; AI sentiment (positive / neutral / negative toward the keyword) from Essential up. We do not ship an MCP server today. We do not sell a share-of-voice dashboard. We send the mention; you decide whether to reply.

If you want those mentions in Clay for scoring and outreach, we publish ready-made templates: Clay templates for sales signals (Business or above for webhooks).

Feature checklist that actually changes the decision

• 1. Do you need Facebook public groups? KWatch yes. Octolens: not on their listed sources.
• 2. Do you need GitHub, Stack Overflow, podcasts, or newsletters? Octolens yes. KWatch no.
• 3. Do you need webhooks + Slack on the cheapest paid tier? Octolens yes (Pro). KWatch: Essential is email-only for delivery; Business unlocks Slack/webhooks.
• 4. Do you need conversation tracking on a hot Reddit or Ask HN thread? KWatch yes (Reddit/HN only). Useful when the keyword already fired and you want every follow-up comment.
• 5. Do you care about mention quotas? Octolens meters mentions. KWatch does not publish a monthly mention cap.
• 6. Do you want MCP so an AI agent can query mentions? Octolens yes. KWatch no (today).

A practical migration / trial path

If you are leaving Octolens, or running both for a week:

• 1. List the platforms that produced useful mentions in the last 30 days. If GitHub and podcasts dominate, stay on Octolens (or keep it for those sources).
• 2. On KWatch, start Free: put your two highest-intent phrases on Reddit and the same two on Hacker News (for example "alternative to [competitor]" and your category phrase).
• 3. Confirm email delivery with a real hit.
• 4. Move to Essential ($19) to add Linkedin/X/Facebook/Youtube and AI sentiment.
• 5. If you need Slack, webhooks into Clay/Zapier/n8n, bulk CSV keywords, or a team, upgrade to Business ($79).

We wrote a separate Zapier/n8n walkthrough here: Automate social media monitoring with KWatch, Zapier, and n8n.

Start Monitoring Keywords

Who should pick which

Pick Octolens if you want one feed across GitHub, Stack Overflow, podcasts, newsletters, and social; if MCP/API on every plan is non-negotiable; and if $159+/month for that breadth is fine.

Pick KWatch.io if your money conversations live on Reddit, Hacker News, Linkedin, X, Youtube, and especially Facebook public groups; if you want per-second alerts without a mention meter; if you want a free Reddit/HN start; or if Essential/Business pricing fits better than Pro/Scale.

Use both only if one product owns community + long-tail sources and the other owns fast Facebook/Linkedin/X/Reddit alerts. Most small teams do not need both.
