Terminal

Log Stream

Simulates a live server log tail — new entries slide in every 650ms with color-coded INFO/WARN/ERROR/DEBUG levels and real-time timestamps.

When to use it

Developer dashboards, terminal-aesthetic hero sections, ops-themed loading screens or ambient backgrounds.

When not to

Light-background UIs (background hardcoded dark navy). Contexts where motion competes with readable content.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change the log interval from 650ms to 400ms, add a new pool entry {l:'ERROR', m:'out of memory: killed process 1234'}, and increase MAX visible lines from 10 to 15.

Safe to edit

log pool entries (pool array)
scroll interval (setInterval delay 650)
max visible lines (MAX=10)
level colors (.trm-lvl-* CSS)
header label text

Keep intact

visibilitychange stop/play guard
IIFE wrapper
prefers-reduced-motion static fallback (fills lines without animating)

Known limitations

Background color hardcoded dark — must edit CSS to change theme
No click interactivity — purely ambient
Timestamps use local clock so they jump on tab switch

Shell SessionSimulates a looping shell session: commands type out character-by-character with a blinking cursor, then output lines appear, then the next command begins.
Resource MonitorRetro BBS-style system monitor showing 6 CPU core bars and 3 memory rows with ASCII block characters; values drift randomly every 420ms.
Build RunnerSimulates npm install + build pipeline in a scrolling terminal; packages, lint/compile steps, and file-change events stream in sequence and loop endlessly.
Network TraceSimulates a live traceroute — hops appear one by one with color-coded latency (green/orange/red); ms values fluctuate after trace completes, then loop.
Diff ViewerA unified git diff viewer that streams a code review in line by line: a file header with +12/-4 counts, a hunk header, then context/addition/deletion…
