Terminal
Build Runner
Simulates npm install + build pipeline in a scrolling terminal; packages, lint/compile steps, and file-change events stream in sequence and loop endlessly.

When to use it
Developer-tool landing pages, loading screens for build/deploy dashboards, or any context needing a credible "code is running" ambient backdrop.
When not to
Non-technical audiences (output is meaningless without dev context). Light-background UIs — background is hardcoded dark (#0d0f0a).
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Edit the OUTPUT array of [text,class] lines, the compact reduced-motion frame, setInterval(tick,440) and hold=3. This is a local demonstration, not a real build.
Safe to edit
- build output (OUTPUT array of [text,class])
- line interval (440ms) and completion hold (3 ticks)
- compact reduced-motion frame below320px
- terminal palette (.bld04-* classes)
Keep intact
- IIFE wrapper
- visibilitychange stop/play guard
- prefers-reduced-motion representative completed build
- whole newest-row trimming after line insertion and resize
- pre-rolled prompt and autonomous tick loop
Known limitations
- Invented output only; no package install, command or real build runs
- Dark terminal palette; no light-mode claim
- Local passive demo; no exposed pause button
More Terminal components
- 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.
- Log StreamSimulates a live server log tail — new entries slide in every 650ms with color-coded INFO/WARN/ERROR/DEBUG levels and real-time timestamps.
- 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 +5/-2 counts, a hunk header, then context/addition/deletion lines…
- Git GraphAn ASCII git commit graph in a green monospace CRT terminal: box-drawing branch rails (│ ├ └ ╲ ╱ ●) run down the left as commits stream in top-to-bottom,…
