Your next customers are complaining about your competitors right now.
Track competitor keywords, layer on a Lens to filter for frustration and intent, and you'll know the moment someone is looking for an alternative.
Start Monitoring FreeThese conversations happen every day.
On Hacker News, on Bluesky, on Lobste.rs. Someone posts "I'm fed up with [competitor], what are the alternatives?" Someone else says "[competitor] just removed a feature I relied on." These are potential customers who've already decided they need something different. The question is whether you hear about it.
Track competitors the same way you track your own brand.

A reply an hour late is barely worth sending.
Hacker News threads move fast. Bluesky replies age out of view. If you're checking manually or relying on daily digests, you're showing up after the conversation has already moved on. Messijo alerts you the moment a match appears.

Google Alerts only covers indexed web pages and misses Bluesky, Hacker News, and Lobste.rs entirely. It also does not catch real-time posts or untagged mentions on social platforms.
Messijo monitors those communities directly and delivers alerts the moment a match appears, with Lenses to filter out the noise before it reaches you.
We currently support listening for keywords on BlueSky, HackerNews, and Lobste.rs. We plan on adding other platforms as we grow. Feel free to let us know which additional platforms you would like us to support.
Mention and Brand24 focus on mainstream social platforms like Twitter and Instagram. They do not cover Bluesky, Hacker News, or Lobste.rs, which is where developers discover tools and talk about products like yours.
If your audience is on those platforms, those tools are missing most of your mentions.
Lenses are AI-powered filters you set up in plain English. Instead of getting every mention that contains your keyword, you describe the intent you care about: “people frustrated with [competitor]” or “posts asking for a tool recommendation.”
Lenses classifies each mention before sending an alert, so you only hear about the ones that matter.
