Reactive Blocks is a professional tool to build robust IoT applications.

Simpler, faster and safer.


IoT Application Gateways

Gateways are critical to IoT. They can react locally if the network is down, add security functions, reduce latency and minimize traffic.

Programming the applications running on gateways is hard as a lot of concurrency and event driven code is involved. A gateway must interact with several interfaces and devices, be monitored and controlled remotely, and have the ability to adapt to changes in the environment. All the stuff must be handled correctly and reliably all the time, even if the network is down.

With Reactive Blocks you can build complex applications for IoT gateways.

From Quick Prototyping to Industrial Solutions

With Reactive Blocks you combine building blocks to make efficient event-driven Java code ready to run on any processor that supports Java. Some of the devices we have used are: QorIQ, CloudGate, Reliagate, Kontron M2M, Raspberry Pi.

Ready-to-use Building Blocks

Why spend hours trying to understand a protocol or piece of hardware? Others may have already done the work for you? Inside Reactive Blocks you will find a comprehensive library of building blocks ready-to-use in your application.

The Team

Bitreactive is the answer to todays shortage in developers needed for making the estimated 50 billion devices connected to the Internet of Things, IoT, in 2020 a reality. The Reactive Blocks developer tool makes programming embedded software for devices possible for any Java developer through abstract visual design rather than writing code.

Bitreactive is an IoT startup based in Norway. Our revolutionary Java based developer tool Reactive Blocks allows for efficient and robust development of reactive or event driven systems for IoT/M2M or other embedded systems. It solves hard problems for developers like concurrency (e.g. handling simultaneous incoming events), leveraging multi-core CPU capabilities effortlessly, reusing code or just understanding and debugging code. Reactive Blocks is available for free download.

Bitreactive is cooperating with key vendors in the IoT/embedded industry to serve developers and application owners with a powerful set of tools, hardware and communication services to develop and maintain deployed IoT/M2M systems efficiently. We are working with partners developing IoT/M2M solutions in a wide variety of industries like logistics, telematics, automotive, oil & gas, home automation, smart energy, smart cities and building control.

M2M, Java, software development, embedded systems, prototyping, IoT, OSGi.
