Quickstart

The shortest possible end-to-end session.

CLI (installed)

npm install -g vibium
vibium go https://example.com
vibium screenshot -o example.png
vibium text

Open a page, save a screenshot, print the page text. That is the entire quickstart.

Why does vibium text not need a URL or selector? Vibium keeps a background browser running across commands; later commands act on the page opened by the most recent vibium go. See Core Concepts for the full mental model.

What you should see:

• vibium go https://example.com — exits with status 0; the browser navigates to the page. No output on stdout is normal.
• vibium screenshot -o example.png — writes the PNG to ~/Pictures/Vibium/example.png and prints the saved path to stdout. The CLI manages screenshot storage for you; -o controls the filename, not the directory. ls -lh ~/Pictures/Vibium/example.png should show a non-empty PNG.
• vibium text — prints the visible page text to stdout. For https://example.com you’ll see the heading “Example Domain” followed by the standard placeholder paragraph.

If any of those don’t match, see Troubleshooting.

CLI (zero-install with npx)

If you’d rather not install anything, the same flow works through npx:

npx -y vibium go https://example.com
npx -y vibium screenshot -o example.png
npx -y vibium text

This is great for CI jobs, throwaway scripts, and demos. To make the rest of this guide copy-pasteable, alias it for the current shell:

alias vibium='npx -y vibium'
vibium go https://example.com
vibium text

JavaScript / TypeScript

import { writeFileSync } from 'node:fs'
import { browser } from 'vibium'

const browserSession = await browser.start()
const vibe = await browserSession.page()

await vibe.go('https://example.com')
const png = await vibe.screenshot()
writeFileSync('example.png', png)

await browserSession.stop()

screenshot() returns the PNG as bytes; you have to write them to disk yourself (unlike the CLI’s -o flag).

Python

from vibium import browser

browser_session = browser.start()
vibe = browser_session.page()

vibe.go("https://example.com")
text = vibe.text()
print(text)

browser_session.stop()

Java

var browserSession = Vibium.start();
var vibe = browserSession.page();
vibe.go("https://example.com");
var png = vibe.screenshot();
java.nio.file.Files.write(java.nio.file.Path.of("example.png"), png);
browserSession.stop();

Agent skill for Codex

npm install -g vibium
npx skills add https://github.com/VibiumDev/vibium --skill vibe-check

After this, your agent can drive the browser by emitting vibium ... commands.
