What it does

OnAir is ephemeral live messaging, built for real-time connection, not endless messaging. Conversations only start when both people are available, creating urgency and presence instead of passive chat. Invites trigger live alerts to bring friends into the moment—if they don’t join, the conversation simply doesn’t happen. No feeds, no scrolling, no distractions. Just focused, time-bound, one-on-one conversations when it actually matters.

    OnAir – create link, receive calls2024 · onair.io · ▲263

    Hello HN community, This is bootstrapped/indie hacker-ish. Would appreciate feedback. What it is: You create a link (e.g. onair/yourname), and anyone can call you from it. Caller uses a web browser to make the call (not dedicated app). You can create as many links as you want, and can direct calls to colleagues in a round-robin or escalation manner. In a way, it's like the "opposite of Calendly"; whereas Calendly is about meetings in the future, OnAir is about immediate meetings. Motivation behind it: One of our SaaS products was struggling to grow. We believed that if we provide…

    Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
