Diffchecker CLI
Last Revised: September 22nd, 2026
Overview
Now you can create cloud-hosted diffs right from the command line. Easily compare 2 files, or compare a current file with the version of itself from the most recent commit.
Why use this instead of a native app? Because your diffs are instantly uploaded so you can share them with others.
Installation
First, make sure you have Node with npm installed from nodejs.org
Then install the diffchecker package from npm:
npm install -g diffcheckerUsage
Compare two files
diffchecker file1.js file2.jsCompare with most recent git commit
To compare a file with its version from the most recent git commit:
diffchecker file1.jsBoth methods will open the diff in your default browser.
Set expiration
By default, the diffs don't expire. You can change it to 1 day, 1 month or forever like this:
diffchecker --expires day file1.js file2.jsSign out
Should you want to sign out:
diffchecker --signout
