og-screenshots

og-screenshots BETA

A CLI to take screenshots of websites and generate open graph images from your own computer. Having a website with a screenshot as an open graph image is a great way to promote your website and attract more visitors.

Why?

• Existing solutions are expensive and subscription based. You usually only need to take the screenshots once. You don't have to pay for a monthly subscription.
• Running your own open graph image generator in the cloud is also expensive. If you use a serverless platform, you'll have to pay for the computing power. If you use a self-hosted server, you'll have to pay for storage and bandwidth.

Features

• Screenshot a single URL
• Capture screenshots of multiple URLs from a sitemap or RSS feed

Requirements

• Chrome browser
• ImageMagick (convert)
• Node.js 16+

Install

$ npm install --global og-screenshots

Or you can also directly execute the command:

npx og-screenshots --url "https://example.com"
