I’m still finding a local instance of Beyond Compare [0] unbeatable.
Especially its table compare feature [1].

Never had a need to do table comparison. Looks like customised csv diff comparison. Will look into and see if i can add it as feature or different page/tool.
I needed it for diffing big csv files where the diff was complicated to understand, and limited to some columns out of 30+ columns.
Might be niche, though.
Some of the CSS is making the numbered steps start at 8 instead of 1. In particular
Can you please share the link of diff? You can copy it from the website after input by clicking share as url button, so that it will easy for me to debug. Thanks for the feedback.
It's based on an inline stylesheet with thousands of rules. The compressed URL is... big.
Do you release the code as FOSS?
Unfortunately No. Planning to monetize through ads once UI is polished.
Why would releasing the code under a FOSS license prevent you from adding ads?
To be honest. Never really thought about it fully. I don't know monetization plan as well. I just wanted to create better private version of diff checker and merge. Will think through and update here.
Not so secure and private then if you're planning to embed a bunch of ad tracking scripts...
The input data will not be passed on to any server which include ads as well. The input will not be persisted so no way the data is accessible other that the user.
This can be tested by disabling the internet and checking the diff.
Bro no one will use a web service and trust it is 100% private. This is an unprovable claim. Maybe it is private now, but you sell this in 5 years and it stops being so.
Maybe a JavaScript ad jailbreaks an iframe and reads this.
There is no beating a locally running program
