Syften

Syften is a live keyword alert tool that scans forums, social media, and review sites for terms you care about. It covers Reddit, Hacker News, X, Bluesky, Mastodon, Indie Hackers, Slack, Discourse, Stack Overflow, Server Fault, Stack Exchange, YouTube, GitHub, Lobste.rs, Dev.to, podcasts, and more. When a matching mention appears, Syften pushes a notification via Slack, email, Discord, or webhook within minutes.

What problem does it solve?

Founders, marketers, and PR teams waste hours manually checking communities for brand mentions or competitor chatter. Syften automates this, filtering by keyword, sentiment, and source, so you can jump on conversations before they go cold—without refreshing tabs all day.

Who is it for?

Best for founders monitoring brand mentions, marketers hunting inbound leads in niche forums, and PR teams tracking sentiment across multiple platforms. It's not designed for mass social listening on networks like Facebook or Instagram; it excels at deep community listening on Reddit, Hacker News, and developer-focused sites.
