Shutter captures screenshots of internal website pages and compares them for differences.

$ npm install -g site-shutter

Quickest way to compare two environments is to use the compare command, navigate to a folder you want the comparisons to appear and run the command.

Compare two sites:

$ shutter compare http://example.com http://staging.com

shutter compare accepts two urls or two folder paths containing screenshots. The screenshots must be named the same in each folder and must be (png)'s

$ shutter compare path/to/original/screenshots path/to/comparison/screenshots

Screenshots

With shutter screenshots it is possible to capture any number of environments then compare them.

Screenshot any number of environments:

$ shutter screenshots master=example.com develop=staging.example.com

Screenshots must follow the convention [ENVIRONMENT]=[DOMAIN] the [ENVIRONMENT] is used for the output folder. Do not use symbols in the environment.

Compare the output with:

$ shutter compare master develop

This tool can also be further configured with the following command line flags.

-h, --help          output usage information
    --version       output the version number

• Be patient the crawling and screenshot process are very cpu intensive
• The first site passed to the command defines the internal page paths for all of the other sites
• Any sites larger than (600 pages +) will fail (Don't try and crawl google :$)

• Usage with docker
• Assign your own config values
  • Concurrency
  • Chunk size
  • Crawler depth
  • And many more
• Module support
• Better windows support
• Spinners / loading bars to indicate time taken
• Performance optimization
