Discover rising Hacker News discussions before they explode. Built-in velocity tracking, pinned threads, OP alerts, instant translation and local-first privacy.
Hey everyone 👋
I built NODUS HN Radar because I kept missing important Hacker News discussions before they took off.
Most HN browsing tools focus on ranking or archives, but I wanted something more focused on signals:
rising posts
velocity changes
active discussions
OP activity
quick thread monitoring
The project is lightweight, local-first and works directly inside the browser.
It started as a small side experiment built in a day using parts of my existing NODUS ecosystem — but it quickly became surprisingly useful in my daily workflow.
Would love to know:
what signals you personally use on HN
which features would make this more useful for you
and what you think is missing from current HN discovery tools
Thanks for checking it out 🙌
Counter to the usual feed-aggregator framing: the value of an HN radar is not "more HN", it is the threshold function. The thing I want from a tool like this is not a stream, it is the ability to say "wake me only when a story crosses 200 points and has more than 50 comments and matches one of these tags."
Asking as a real user, not a gotcha: do you treat the user-set thresholds as a first-class config, or is the current product mostly recommendation-driven? The answer shapes whether I would replace my crude saved-search workflow with this. Either answer is fine, just changes my expectations.
Nice! what's the early tell before 'before they explode'? upvote velocity in the first 30 mins, comment-to-upvote ratio, or normalising for time-of-day so a 7am post isn't measured against peak hours? good luck with it, will check it out.
about the use case here. the people most likely to want early HN signal are founders doing competitor monitoring, recruiters, investors, or people trying to comment early for visibility. those are pretty different users with different needs. which one were you actually building for and does the current feature set reflect that or did it end up somewhere in between

Who hunted NODUS HN Radar?
NODUS HN Radar was hunted by M. M. Carvalho. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
