Heartbeat tranforms REST endpoints into streaming APIs painlessly, with zero lines of code. Heartbeat transformed streams are accessible from the dashboard, or universally via Javascript and REST based APIs. With the flick of a switch, heartbeat can store updates for up to six hours. It also provides an API and a data view for visually accessing historical data. Heartbeat takes REST API endpoints and transforms them into realtime APIs. Behind the scenes, heartbeat runs a worker process that will poll the REST API at the polling frequency you specify in the dashboard and show the changes via an elegant realtime endpoint.

Anyone can host a live audio stream from their browser tab or system audio. Listeners join, music recognition identifies tracks automatically, and there's chat with 7TV emotes. No account required - you get an anonymous code and you're in. We're running demo rooms that stream NTS Radio and SomaFM 24/7 (indie project, not affiliated - we backlink to the original stations).

That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
