We’ve all been there…You have to update a (WordPress) website for one of your clients. You update the CMS, the plugins, the theme. After the update you check some web pages and everything looks good. After one hour the client calls you (not in a good mood) because some buttons disappeared and the contact forms don’t work anymore. There must be a better way.

This is why we created WebDiff. WebDiff is a desktop app available for MacOS and Windows that allows you to compare a website before and after an update, allowing you to spot any unwanted change. Fewer errors, less stress, more satisfied clients.

A: Hi sato! Yes we have in our plans to develop the visual comparison also on mobile resolution. At the moment it is not yet in our roadmap but we will surely develop it in the second half of the year!

Q: Automated or scheduled?

Will this notify me if a webpage changes or breaks? Does it crawl the site and pages automatically or can we schedule it?

I’m just a bit confused by the language used to describe how the software works.

A: Hi Mahyar! WebDiff currently requires you to run comparisons manually, meaning you have to go into the app and run them whenever you like. Automatic or scheduled comparisons is something we have in mind but it's not on our roadmap yet. You can also check out our documentation for more information: https://docs.webdiff.app/

Q: Full website comparison?

Was reading thru the previous question about comparing a full website instead of just a page and it sounds like it's possible but you have to add all the urls. Is it possible to add the sitemap instead? What would be even better is if we could add the domain and then have a toggle for full site comparison or single page.

Also, setting it up in advance and running comparisons on a schedule or beng able to set a trigger to run at a specific time (eg: whenever the site has been updated or a change has been made to a page), would be super helpful!

A: Hi! Yes, at the moment you need to insert the urls manually, but support for automatic insertion via sitemap is already in our roadmap (We will soon publish the roadmap here and/or on our website, so you can always know what's cooking!) Thanks also for the suggestion on scheduling, we will definitely take it into consideration for future developments!
