What can you do with Core?

Create a real-time data stream

Bring your real-time data easily into Core. Our simple flow allows for quick setup of data types and fields, through auto-detect or drag and drop. Monitor all your stream statuses in Core, and easily add them to canvases, dashboards or products.

Process your streams on a canvas

Need to clean, process or visualise your streams? Core's visual editor has 150+ modules to help with that, and you don't need to know any code to do so. Run real-time or historical processes, and share your results with one click.

Visualise your data with a dashboard

Need a quick visualisation of your data? Any chart or table modules you use in canvases can be added with a click to a customisable dashboard. Combine visualisations to monitor processes or share with others.

Create and sell a data product

With Streamr's integrated Marketplace, unlocking the value of your data streams is just a few clicks away in Core. Add your streams, set up some details, publish your product and earn DATA on the Marketplace.

Canvas modules for (almost) everything
