As an iPad Pro owning front-end developer, I’ve often been a bit frustrated at the lack of developer tools for testing and debugging websites on the go. So I created Web DevTools+, a free Safari extension for iOS and iPadOS. It's free with no adverts, tracking or subscriptions.

Happy to hear any feedback, suggestions, feature requests, bug reports!
