opencode-sysinfo

OpenCode TUI plugin that shows system info in the sidebar: hostname, project, RAM, CPU (with sparkline), battery status, and session duration.

Motivation

I work on multiple laptops — home, office, client sites — all accessed via SSH from a single terminal. Switching between them, especially on the same project, it's easy to lose track of where you are. A quick uname -n helps, but it breaks flow.

This plugin puts the hostname, project directory, resource usage, and battery level right in the OpenCode sidebar. At a glance, you know which machine you're on, how it's doing, and how long you've been connected. No more wondering "am I on the office laptop or the client one?"

Example

┌─ 🖥 Env Info ──────────────┐

Installation

opencode plugin opencode-sysinfo

Or add to your tui.json manually:

{
  "plugin": ["opencode-sysinfo"]
}

OpenCode will auto-install the package from npm on next startup.

Requirements

• Linux (tested). Battery reading requires /sys/class/power_supply/BAT0.
• OpenCode with TUI support.

Development

git clone <repo>
cd opencode-sysinfo
bun install
bun test        # run tests (20 tests)
bun run build   # build dist/
