Introduction

Prismo is a TUI-based telemetry viewer for debugging systems directly in a terminal.

It is built for engineers who want to inspect live data quickly without leaving the shell. Prismo has minimal dependencies, can be deployed, and is designed to be extended to whatever telemetry source you may have with a plugin system. It loosely follows vim flow with a focus on keyboard navigation without giving up mouse support.

Typical use cases include:

  • debugging Linux-based embedded systems
  • watching live values from robots, spacecraft, or test rigs
  • inspecting low-level comms like serial, CAN bus, or network traffic

Current Capabilities​

Today Prismo includes:

  • nested channel trees with collapsible namespaces
  • support for multiple plugins at once, with a unified view of all their telemetry
  • live rate calculation and stale state markers
  • numeric history charting and text/bytes renderers
  • vim-like navigation and filter prompts
  • mouse interaction in scrollable panes
  • OSC 52 clipboard copy support

The docs currently focus on local use, plugin development, and the in-repo architecture.
