# What Is Serial Studio? > Serial Studio is a cross-platform app that turns live data from a device into a real-time dashboard. What it does, how the pieces fit, and where to start. > > Overview · May 18, 2026 · by Alex Spataru · https://serial-studio.com/blog/what-is-serial-studio When people first hear the name "Serial Studio," they usually picture a serial-port terminal. That is where it started, but it is not what it is now. Serial Studio is a cross-platform desktop application that takes a live stream of data from a device and turns it into a real-time dashboard: plots, gauges, maps, 3D views, and more. This is a short tour of what it does and how the pieces fit together. ## The one idea it is built on Everything follows from a single decision: the device sends data, and the host decides what that data means. Your firmware's only job is to emit values. The laptop running Serial Studio owns everything about how those values are parsed, displayed, and recorded. That separation is what lets the same tool work with a breadboard one day and a vehicle bus the next, and it is worth understanding early. [How Serial Studio Turns Bytes Into Datasets](https://serial-studio.com/blog/frame-parsers-and-the-empty-parser) goes deeper on it. ## Three ways to use it Serial Studio has three operation modes, from zero-effort to fully custom: - **Console** shows the raw stream. It is a diagnostic view for confirming a device is talking at all. - **Quick Plot** reads comma-separated numbers, one line per sample, and draws a live plot for each value with no configuration. It is a quick way to check an Arduino or ESP32 sketch. - **Project File** is a dashboard you design on the host: named datasets, chosen widgets, and a frame parser for anything richer than CSV. You can read more in [Operation Modes](https://serial-studio.com/help/operation-modes). ## Where the data comes from Serial Studio connects through ten drivers. Three are in the free edition (Serial/UART, TCP/UDP, and Bluetooth LE); the rest are Pro (MQTT, Modbus, CAN Bus, audio input, raw USB, HID, and Process I/O). Whatever the source, every driver feeds the same pipeline, so the dashboard above it never has to care where the bytes came from. That is why it is much more than a serial tool, which is a topic of its own in [Serial Studio Isn't Just for Serial Ports](https://serial-studio.com/blog/not-just-serial-ports). ## What it draws, and how it reads the data On the visualization side there are 15+ widgets: line and multi-line plots, an FFT, gauges, bars, meters, a compass, accelerometer and gyroscope, a GPS map, data grids, LED panels, and a terminal. Pro adds 3D plots, XY plots, a waterfall spectrogram, a live camera view, and a scriptable canvas. On the input side, a frame parser turns each incoming frame into an array of values. Parsers come in three forms: built-in templates you configure with a form (no code), and JavaScript or Lua for custom formats. Per-dataset transforms then convert raw readings into real engineering units, which is covered in [Calibrate Sensor Data: Counts to Real Units](https://serial-studio.com/blog/sensor-data-transforms). ## Recording and automation Sessions record to CSV in the free edition, and to MDF4 with a full session database in Pro. Beyond the UI, Serial Studio exposes a TCP API and a gRPC server, plus an MCP server so an AI assistant can drive it. You can automate a whole workflow without clicking anything. ## Native, and quiet about it Serial Studio is a real desktop application built with Qt 6 and C++20, running on Windows, macOS, Linux, and Raspberry Pi. It reads hardware directly, aims to keep a 60 FPS dashboard responsive at high data rates, and collects no telemetry about you. ## Free and Pro The core is free and open source under the GPLv3: the three main drivers, the standard widgets, the project editor, parsers, transforms, CSV export, and the local APIs. Pro adds the advanced drivers and widgets, MDF4 and the session database, file transfer, the AI assistant, and a commercial-use license. The [pricing page](https://serial-studio.com/pricing) has the full split. ## Where to start The simplest first run is Quick Plot: print a couple of comma-separated numbers from a microcontroller and connect. When you are ready for a designed dashboard, the [getting-started guide](https://serial-studio.com/help/getting-started) walks through the first project.
