Q: Missed the AppSumo Deal - Any Chance of a Return?
Hey Webdiff Team,
I'm reaching out because I totally missed your deal on AppSumo! I came across it just recently, but didn't realize it would disappear so quickly. It's a bummer, because the tool looks really great.
Quick question: Are you planning on coming back to AppSumo anytime soon? Or perhaps do you have any other offer running right now?
Thanks a lot!

A: Hi, thanks for your interest in WebDiff! I'm sorry you weren't able to purchase it on AppSumo 😔 We don't currently have plans to return to AppSumo, but if you'd like, you can purchase it directly from the website using the discount code PROMO20 😁
Q: Microsoft Defender SmartScreen prevented an unrecognized app from starting
I just downloaded the Windows version and got this warning in Windows 11: "Microsoft Defender SmartScreen prevented an unrecognized app from starting." Metadefender Cloud also flagged it as "likely malicious" with a 75/100 threat score.
As we work with many clients that require HIPAA, SOC2, or PCI DSS certification, this creates a situation for our IT department to deal with, and the answer is usually "no, we will not allow installation on our network."
So, do you have any solution for this?

Hi, Why is there no company Face person like founders sharing socials so we can attribute the ownership and responsibility to someone? Nobody wnats to take responsibility but they want access to our private computer/network? Seems sketchy. I don't want to return but sadly there's no secure web-based version

Awesome response, thank you for correcting me there is actually a clearly traceable "papertrail"! My underlying concern is that my customers need top tier security and I use the computer for work and cant install software other than the most private/secure ones like microsoft, so I'll have to use your software in another windows user with limited features to avoid using a vm. Docker would be great
Multiple questions in one but here are my main questions: Will WebDiff identify images that don't display (missing images)? Will it identify changes in behavior of sliders or carousels, accordions or tabs? Will it identify visual changes resulting in changes outside the site such as browser updates? Will it find malicious code injection, pages, files, images, popups in the event of a site being hacked? Will it monitor WordPress sites you don't have access to log in to?

Regarding your questions:
- Yes, it's possible to identify images that aren't displayed using visual comparison. - Visual comparison can't verify behavior changes (e.g., animations or transitions) because it's a static comparison performed on snapshots. - The comparison is performed using a recent version of Chrome, so any unusual behavior on...

Hi! Ok, I understand, I wasn't aware of this platform 😁 WebDiff works with any public website, no matter what tool the site is built with 😁
Q: How extensive can a comparison be?
