Eclipse Streamsheets

The perfect companion for Mosquitto

Our no-code user interface is the all-familiar spreadsheet. But that’s all what Streamsheets have in common with traditional spreadsheets.

While spreadsheets are client apps which work with bound and de-coupled batches of data, Streamsheets continuously process, aggregate, visualize and transform unbound data streams in real-time as a server app (microservice).

Streamsheets were designed with publish/subcribe streaming protocols like MQTT, Apache Kafka or AMQP in mind, but they also work perfectly with REST-based protocols (request/response)

Eclipse Mosquitto

Edge & Cloud: Streaming data everywhere

Eclipse Mosquitto is the most popular MQTT broker in the world and the perfect streaming platform for Streamsheets. Mosquitto supports unlimited hierarchical topics and the highly flexible publish/subscribe communication pattern.

With the Mosquitto broker you can connect sensors, devices and apps far more flexible than in the request/response communication pattern of traditional client/server architectures.

Eclipse Mosquitto supports guaranteed delivery of messages which allows use cases not only in IoT and Smart Factory, but also in financial and other non-IoT applications.

We include extensive charting features including custom and time-series charts that update with real-time data. No need to install third-party chart extensions. Have a look at our chart gallery.

or Cyclic

Streamsheets calculate their formulas on each incoming stream event or based on a cycle timer. You can set the cycle timer to control how often a Sheet receives, processes and sends data.


Real-time event streams from technical or financial applications can have a very high frequencies. Streamsheets are able to run up to 1000 cycles per second to guarantee precise operations.

24/7 Operations

Streamsheets run on their own, even if you close the browser window. They run as microservices, 24 hours a day, receiving data from multiple sources, transforming it, and sending it out again.

& Premium

Both Mosquitto and Streamsheets are Eclipse IoT open-source projects which are commercially sponsored by Cedalo. We also offer premium editions of the products under the name "Cedalo Premium Platform"

& Cloud

Our products run as managed service in the Cedalo Cloud, on your AWS or Azure account or on-premises under any major operating system. They even run on edge devices with weak CPUs or on the Raspberry Pi.
