How do you compare code snippets when reviewing changes outside Git?

Hi everyone,

I’m curious how other developers compare code snippets or text changes when they are working outside a Git workflow.

For example:

  • Comparing API responses
  • Reviewing configuration file changes
  • Comparing generated code
  • Checking content updates before publishing
  • Verifying copied code snippets from documentation

I usually use Git when possible, but sometimes I need a quick side-by-side comparison for individual files or text blocks.

Some tools I’ve come across include online diff viewers, IDE comparison features, and browser-based tools such as Text Differ.

What tools or workflows do you use for this type of comparison?

I’d love to learn about Mozilla community members’ approaches and recommendations.
