OpenUI5
Summary
Compared to mainstream frameworks, OpenUI5 has a relatively small global market. This framework is moderately popular in enterprise contexts (such as SAP projects). As of 2025, OpenUI5 holds 0.11% of the market share and ranks fourteenth overall.
OpenUI5 is moderately easy to use. It has prebuilt UI controls, thorough tutorials, and professional SAP Fiori guidelines, and it works smoothly on tablets, smartphones, and computers.
OpenUI5 is heavier than other frameworks — other frameworks like React, for example. Additionally, its performance depends upon developers' optimization. It does have some strengths (SAP integration, accessibility, and reliability, amongst others). However, OpenUI5 is not a practical choice for general web development; a more practical framework for this purpose would be, for example, NestJS.
NestJS
Summary
NestJS is one of the most popular JavaScript frameworks; this is because NestJS is modular, scalable, and integratable with TypeScript.
NestJS is capable of handling high levels of traffic with reasonable speed and efficiency. It has great resource utilization due to its dependence injection and modular architecture. Built-in exception filters and validation significantly reduce downtime, which noticeably enhances reliability.
For most developers, NestJS will become easier to understand with enough continued use. Less experienced developers might find NestJS somewhat challenging to use due to its complex architecture, which consists of three primary components: controllers, modules, and providers.
Sails.js
Summary
Sails.js is not among the top five Node.js frameworks. However, it is moderately popular, with a steady adoption rate in enterprise projects and custom software projects. Approximately 304 different companies worldwide use Sails.js. Sails.js has a strong presence in the United States, India, France, and Germany.
This framework's efficiency and speed are dependent upon the manner in which the framework is used. It has solid performance for building full-featured Node.js applications. Additionally, it has excellent scalability, as its MVC structure helps maintain stable performance in apps of various sizes.
Sails.js is generally easy to use; this is because it is designed to be used for building full-featured Node.js applications. However, depending upon the specific project, this framework's ease-of-use may vary.
