What tools do you use to compare code and text differences during development?


Hi everyone,
I'm interested in learning how developers compare code, configuration files, JSON data, or text changes when working outside of version control systems.
Common scenarios include:
- Comparing two versions of a script
- Reviewing generated output
- Checking configuration changes
- Comparing API responses or JSON files
- Reviewing documentation updates
I've used IDE comparison features and online diff tools. One browser-based tool I've found useful for quick comparisons is Text Differ:
I'm curious what workflows or tools other community members prefer. Do you rely on built-in editor features, version control diffs, or dedicated comparison tools?
Looking forward to hearing your experiences.

If your workflow is MATLAB, apart from built-in Git tools like the proprietary git diff, I recommend using MATLAB's built-in function visdiff — it supports all of what you listed. There are also GUI tools. https://www.mathworks.com/help/matlab/ref/visdiff.html

I've typically use VS Code compare files feature since I spend most of my time in that app. Prior to that, I've used either WinMerge (Windows) or Beyond Compare (which has a better UI in my opinion).
