Monitors Reddit, Hacker News, X, and forums for keyword mentions and sends alerts.
Syften watches Reddit, Hacker News, X, GitHub, forums, YouTube, and the wider web around the clock for mentions of chosen keywords, then pushes alerts through email, Slack, API, or webhooks. It's built for founders, marketers, indie hackers, support teams, and agencies who want to catch brand mentions, competitor activity, or buying-intent conversations as they happen rather than searching manually. The company is based in Krakow, Poland, and has been running since 2019. Plans scale from a small number of tracked keywords and daily results up to unlimited archive access and webhook delivery.
Entry plan is $29.95/month for 3 keyword filters and 100 daily results; a 14-day free trial requires no credit card.
Use tool ↗Syften covers a wider set of sources than most brand-monitoring tools — Reddit, Hacker News, and GitHub alongside the usual social platforms — which matters most for developer-facing and indie-hacker products where those communities carry real buying signal. Several years of operation and a clear Krakow base give it more track record than most of this batch.
Watch out: Check the daily-results cap on the entry plan against your actual keyword volume — high-traffic keywords can burn through it fast.
