Free launch-data feeds
Everything this site runs on is a set of static files you're welcome to use — no key, no rate limits beyond common sense, CORS enabled. Data originates from Launch Library 2 by The Space Devs (please credit them); a link back to rocketlaunchtracker.com is appreciated.

Example
const r = await fetch("https://rocketlaunchtracker.com/data/launches.json");
const { generated, results } = await r.json();
const next = results.find(l => new Date(l.net) > new Date());
console.log(`Next: ${next.name} at ${next.net} from ${next.pad.location.name}`);
Push alerts (ntfy)
We publish to free public ntfy topics ~30–60 minutes before every Go/TBC liftoff. Subscribe in the ntfy app to rocketlaunchtracker-alerts for everything, or a per-provider topic like rocketlaunchtracker-alerts-spacex, rocketlaunchtracker-alerts-rocket-lab, rocketlaunchtracker-alerts-united-launch-alliance (provider name, lowercased, non-alphanumerics as dashes).
Fair use
These are static files on a free host — cache on your side, don't poll faster than the 6-hour refresh, and don't strip attribution. If you build something with this, tell us — we'll link the best ones from here.
