An app that you now have to maintain. The point of spending $5 a month is not to have to deal with that hassle. It makes zero sense to do it to save money. SaaS customers really aren’t in the business of SaaS cloning.

The only people that might look into cloning an existing business are competitors, and by virtue of being competitors they already were a danger to the business.

Companies are happy to pay for SaaS products that are being run by a team of people who are experts in that domain and are also responsible for anything that goes wrong. Cloning something in house, no matter how it's done, doesn't bring you the subject matter experts and it shifts the responsibility/blame internally.

If you have the resources to clone other "apps" instead of working on your own, either you have too many free resources or your "app" is too simple and someone will copy it using fable, allegory, apologue, parable, or the the next LLM that ships in the next few days.
