CANviz

A browser-based CAN bus analyzer. Plug in. One command. Analyze. CAN bus tools are either expensive, locked to proprietary hardware, or require compiling from source. CANviz is different: it runs in your browser, installs with one pip command, and works with any USB CAN adapter including adapters that cost under $10. No GUI install. No driver setup. No account. No internet connection. Whether you are debugging an ECU, commissioning a servo drive, analyzing J1939 truck traffic, or working on a robot arm over CANopen, CANviz puts every frame, signal, and protocol event in front of you immediately. CANviz is the open-source project Chanchaldhiman/CANviz (https://github.com/Chanchaldhiman/CANviz) by Chanchaldhiman, released under MIT. Ion packages it unmodified from commit bbddde95ad87, adding only a manifest, an icon and a start script.

Not rated. Nobody has said who this app is suitable for, so Personal Clouds and the Oikou app treat it as 18+.

Internet

It asks to reach these hosts, and no others:

USB and serial devices on your Personal Cloud’s computer

• Can talk to a serial port on your Personal Cloud’s computer that you choose (a printer, a board, a Zigbee stick): The serial device it talks to (a USB-serial cable or board) (serial)
• Can use a USB device plugged into your Personal Cloud’s computer that you choose (raw access can change its settings or firmware): The USB device it talks to (usb-device)

You pick one device for each on your Personal Cloud, and can let it only read it. It gets that device alone, never the others plugged in; one it may write to is its to command.
