Hi guys! 🙋🏽‍♂️ My name is Ahmad Wali Sidiqi and I'm a software developer based in Vancouver, Canada. When I first launched Diffchecker in 2011, I wanted to create a simple online tool that would help people check the difference between two text files. This is why I was so surprised when Diffchecker got hunted on Product Hunt (without me even knowing!) and even made it to the #3 Product of the Day! Since then, my teammates and I have been working closely with our users trying to figure out what would make Diffchecker more useful to our community. To improve our tool, we added dozens of new features such as comparing images, PDF files and even folders (however, this feature is only available in our desktop version). Now that we considerably expanded Diffchecker's functionality, we decided to launch Diffchecker 2.0 on Product Hunt! With Diffchecker, you can now easily check the difference between: 🤖 Code 📔 Text files 🚀 PDF files 🌁 Images 💾 Folders ⛅️ Diffchecker also lets you create cloud-hosted diffs right from the command line and easily compare 2 files. We are always looking for more features to implement so we would love to hear your feedback or thoughts on how we can make Diffchecker better :) - Ahmad

DiffChecker has been one of my most-used tools for 10-15 years, serving as a near-daily essential across various tasks and use cases. While I occasionally use VS Code for non-code text comparisons, DiffChecker’s functionality, UI, and visual clarity make it far superior for precise text edits and comparisons. I’ve explored alternatives like FileMerge, but nothing has come close. For me, DiffChecker ranks among the top 10-15 most valuable tools I use regularly. At the same time, I find it surprising how undervalued it is and how many people overlook it, despite its ability to speed up tasks and significantly reduce cognitive load.
