TimelineJS alternatives

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.
