Take Website Screenshots in Ruby
Capture screenshots from Ruby with Net::HTTP or any HTTP library. No Capybara, no PhantomJS — just a simple API call.
Code Examples
require 'net/http'
require 'uri'
uri = URI("https://snapapi.tech/v1/screenshot?url=https://example.com&api_key=YOUR_KEY")
response = Net::HTTP.get_response(uri)
File.open("screenshot.png", "wb") { |f| f.write(response.body) }
puts "Screenshot saved!"Try It Live

Why SnapAPI?
No Browser Setup
We run Chromium so you don't have to. No Puppeteer, no Selenium, no drivers.
PNG, JPEG, WebP
Choose your format. Set quality. Get optimized output.
Mobile Emulation
9 device presets — iPhone, Pixel, iPad, desktop. One parameter.
Full Page Capture
Scroll the entire page and stitch into one image. Automatic.
Element Selector
Capture a specific element by CSS selector instead of the whole page.
Dark Mode
Emulate prefers-color-scheme: dark to capture dark-themed pages.

How It Works
1. Sign up for a free API key — 100 screenshots/month, no credit card required.
2. Make a GET request to /v1/screenshot with your URL and API key.
3. Receive a pixel-perfect screenshot as a binary image, or JSON with metadata if meta=true.
That's it. No browser installation, no Chromium management, no headless infrastructure to maintain.
