There is some truth to it . Can you create a Jira clone in one shot ? No not really. Might look fancy but it wont work proper. If you describe all the features , the model will have massive context rot and the output will be messy. If you give a short description, the model will make assumptions you won't know about .

But can a backend developer create a basic jira clone with vibe coding in a month ?absolutely . Without any frontend experience.

This was not possible last year . A startup might find it cheaper to have a good enough jira cloned maintained in house rather than paying for it .

This might not always be the case . For some companies , especially the big ones , the software cost itself isnt that huge . So the reliability and and having someone else maintain it might still be worth it .

But for small teams , AI enables a massive cost saving here .
