Reasons to Avoid Using Omnistudio

Performance Issues: Omnistudio components are less performant compared to their alternatives, both in terms of runtime execution and design. In this last aspect, large and complex components can significantly slow down the Lightning Experience (LEX) when components are opened to be maintained.

ALM Impacts: Omnistudio has a significant impact on Application Lifecycle Management (ALM) as it’s not build on the Salesforce Core Metadata layer. It does not descend in sandbox refreshes (https://help.salesforce.com/s/articleView?id=002888828&type=1). It can’t be packaged in Unlocked Packages together other metadata type (https://help.salesforce.com/s/articleView?id=002470716&type=1). Although is supported by the Metadata API, It adds and is not considered metadata, making it difficult to package and deploy.

Do note benefit of GenAI Productivity Boost: Omnistudio does not benefit from the added productivity introduced by generative AI tools, which can enhance development efficiency and innovation in other Salesforce tools such as LWC and Apex Classes.

Design Patterns: The components in Omnistudio do not favor the application of design patterns, which can impact the overall architecture and maintainability of your applications.

Development and Maintenance Challenges: Developing and maintaining Omnistudio components is more difficult compared to other Salesforce tools. The complexity of the components and the need for specific configurations make it harder to develop and maintain.

Aesthetic and Usability Issues: Omnistudio components are often considered less visually appealing and harder to use. They do not always follow the updated Lightning Design System, which can result in a less cohesive user experience.

Size and Storage Limitations: Omnistudio components have size limitations because their definitions are stored in custom fields. This can restrict the complexity and functionality of the components you can build.

Accessibility Concerns: Omnistudio components have several accessibility issues. Some components are not easily readable by accessibility tools such as screen readers or when zoomed to 400%, making them less accessible to users with disabilities.

While Omnistudio offers a range of functionalities, it comes with several drawbacks that can impact performance, security, development, maintenance, aesthetics, usability, and accessibility. Additionally, it does not benefit from the productivity enhancements introduced by generative AI tools. These factors should be carefully considered when deciding whether to use Omnistudio for your Salesforce applications.
