What is Oscilloscope Online?

Oscilloscope Online is a lightweight, browser-based serial plotter powered by the Web Serial API. It enables anyone to visualize and monitor signals, sensor data, and other values directly from a microcontroller (MCU) — without needing costly oscilloscopes or complex data loggers.

What's Next?

Oscilloscope Online is evolving into more than just a visualization tool. The goal is to create a collaborative hub for data analysis, research, and experimentation. Here are the major updates currently planned:

Cloudoscope

A personal cloud workspace for every user. With online accounts, you'll be able to securely store, organize, and access your data indefinitely. Cloudoscope will also provide APIs for seamless uploading, downloading, and sharing of datasets.

Datawave

Building on Cloudoscope, Datawave will introduce plug-and-play AI assistants. These bots will be trainable on your datasets, helping you uncover insights, automate analysis, and accelerate research with minimal setup.
