Streamr is the missing real-time data protocol for the decentralized web

Publish and subscribe to cryptographically secure data streams with a few lines of code, trade real-time data on the Marketplace or try Core, our real-time data toolkit.

Use Core

Streamr’s mission is to build decentralized infrastructure for real-time data, replacing centralized message brokers with a global peer-to-peer network. By relying on cryptography instead of trust, the open-source network enables data sharing and monetization in IoT and smart cities, business consortia, and the decentralized web (Web 3.0).

Streamr Blog

Streamr is a distributed open source project crowdfunded in 2017, with contributors across the world. It was started in reaction to the dominance of the Big Five tech giants, with the core belief that decentralized infrastructure can deliver a healthier distribution of money and power, as well as unlocking brand new use cases.

P2P pub/sub for real-time data

The Streamr Network is a decentralized, scalable publish/subscribe network, designed for low-latency, real-time data from IoT sensors, machines, and other smart devices — a neutral data backbone for the machine data economy. It is simple to work with, the 5 lines of code below show how to send your data to the network.

Data Marketplace

Buy & sell real-time data

The Data Marketplace is an open source app built on top of the Network that enables anyone to easily share or monetise real-time data. It also enables brand new sources of data like digital Data Unions, via the upcoming Community Products feature. It can also be forked to enable private instances.
