Which ServiceNow component allows users to customize the platform without writing code?

Flow Designer provides a no-code/low-code environment for building complex workflows, integrations, and process automations. It utilizes pre-built actions and logical flows, making it accessible for non-developers to customize and extend platform functionalities.

Script Includes are reusable server-side JavaScript code snippets and require writing code.

Business Rules are server-side scripts that run when a record is inserted, updated, deleted, or queried, requiring code.

ACLs (Access Control Lists) are security rules that restrict access to records and fields, and while configured, they don't primarily customize platform logic without code in the way Flow Designer does.
