    Ducksboard launched a new API and is giving away free subscriptions▲45

    We've just launched our new, three-headed API (part of which is an open WebSocket server) and we'd like to thank this community for the all the help, feedback and inspiration. Ducksboard launched as a Show HN and countless hours that should've been dedicated to developing the product went into browsing the site (until we discovered noprocrast, yay!) For the next 24 hours we're giving away free, full-featured plans to everyone with a HN account more than 10 days old, sign up at https://app.ducksboard.com/signup/hn/ These plans will always be free, but we can't promise we won't try to upsell…
