Show HN: Stream live open data in two commands
This article introduces the Hypermass CLI, a tool designed to help users subscribe to and sync live open data streams directly to their local machines. It provides a practical guide on how to install and use the command-line interface to manage real-time data payloads.
Why it matters
It offers a streamlined, developer-focused solution for accessing and archiving real-time open data, which is essential for researchers and data enthusiasts working with live telemetry or public datasets.
CLI On this page Getting Started The Hypermass CLI delivers live data from streams to a folder on your machine, in real time as it's published.
See the installation instructions (don't worry, they link back here when you're done).
If you opted just to try it rather than install, remember to type ./hypermass (or hypermass.exe for windows) in the commands below rather than just hypermass .
