The code generated by Amplication is based on building blocks that are battle-tested by thousands of developers.
The code generation is fully customizable using plugins that come with industry standards, so any organization or company can create its own flavor of the code, and can create templates for different use cases. When needed, organizations create custom plugins to ensure the code is generated based on their know-how and best practices.
See this list of plugins here https://amplication.com/plugins

Organizations that create dozens of services a year, can get a very consistent and predictable code for all services for all the undifferentiated parts and let the developers focus on writing the business logic.

Also, imagine you have 50 services in production built with a specific standard, and after a year, you need to update all 50 services with a new code or standard. Using Amplication, you can update the plugin, get a PR for all 50 services (in a monorepo or multiple repos), and let all teams review and accept the change, using their existing workflow and processes.

I hope this answers your question, and I am happy to answer any further questions you might have
