I got tired of manually comparing two lists (think: emails, product SKUs, code, whatever) and built CompareLists.org to make it painless.
You just paste your two lists, hit compare, and instantly see what’s unique to each list, what matches, and any duplicates. It handles thousands of lines, works right in your browser (no data leaves your device), and you can export results as CSV/TXT/JSON. There are options for case sensitivity, whitespace, and more.
It’s free and there’s no signup. I’d love for you to try it out and let me know what you think—or if there’s a feature you wish it had. Feedback (and bug reports) super welcome!
Thanks!
