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 serial plotter. The goal is to create an all-in-one online plotter for literally any possiblle usecase. There's already an update in the works!!

Oscilloscope 3

An all-in-one online plotting tool featuring on-the-fly math expression evaluation and code execution, a classic serial plotter, and an advanced audio visualization module. Additionally, integration with Google Forms is planned to enable direct plotting of survey results.
