All performance data presented below is derived from the official JS Framework Benchmark (Keyed) executed in Chrome 131. SimpliJS achieves near-native speeds by utilizing a direct Proxy-to-DOM engine.
{{text}}
` }) export class AppComponent{ text="Hello" change(){ this.text="World" } }{text}
${state.text}
` }; });Why SimpliJS wins SimpliJS performs the task with very direct and readable code. There is no component setup, no state management, and no framework lifecycle involved. The developer only selects the element and attaches a click handler. The intent of the code is immediately clear, which reduces development time and cognitive load. For simple DOM interactions, SimpliJS avoids the structural overhead required by component-based frameworks.
Why SimpliJS wins The code directly expresses the action: select the element and toggle a class. Frameworks such as React, Vue, or Angular require state variables and reactive bindings just to toggle a CSS class. SimpliJS keeps the logic extremely close to the DOM operation itself, which makes the code shorter and easier to understand.
Why SimpliJS wins Showing or hiding an element is a basic DOM task. SimpliJS provides a straightforward method that maps directly to this behavior. Component frameworks require conditional rendering or state changes to achieve the same result. SimpliJS removes that extra layer and lets developers manipulate the element directly.
Why SimpliJS wins SimpliJS handles input events in a very direct way. The developer simply listens to the input event and updates the preview element. There is no reactive data model or component state required. This makes the code easier to write and easier to maintain for simple UI updates.
Why SimpliJS wins For a simple counter, frameworks introduce state systems and component rendering. SimpliJS keeps the logic minimal: increment a variable and update the text in the DOM. The code is shorter and more transparent, which is ideal for small interactive features.
Why SimpliJS wins SimpliJS allows developers to iterate over an array and append elements directly to the DOM. The logic is familiar to anyone who knows JavaScript loops. Frameworks require templating or component rendering mechanisms, which adds complexity for a very basic task.
Why SimpliJS wins Filtering a list becomes a straightforward process: read the input value and update the display of each item. SimpliJS lets developers directly manipulate elements without setting up reactive data structures or computed properties. This keeps the code simple and predictable.
Why SimpliJS wins Sorting is essentially a JavaScript array operation followed by updating the DOM. SimpliJS allows this logic to stay simple and procedural. Frameworks often involve state updates and re-rendering, which adds unnecessary structure for a simple sorting operation.
Why SimpliJS wins SimpliJS works naturally with native browser APIs like Fetch. Developers can use standard JavaScript without framework-specific patterns. The data can be retrieved and immediately displayed without involving component lifecycle methods or state systems.
Why SimpliJS wins SimpliJS allows developers to fetch data and directly generate DOM elements from the result. The flow is easy to follow: fetch data, iterate through it, and append elements. This direct workflow avoids the component rendering layers used in many frameworks.
Modal content
Why SimpliJS wins Opening and closing a modal is a simple UI behavior. SimpliJS allows developers to directly show or hide the modal element. Frameworks typically require state variables and conditional rendering. SimpliJS removes that overhead and keeps the interaction simple.
Why SimpliJS wins Tabs are essentially a UI visibility problem: show one section and hide the others. SimpliJS expresses this logic clearly with simple element selection and show/hide operations. Framework implementations often require component state management, which is unnecessary for such a simple interaction.
Content
Why SimpliJS wins The accordion behavior only requires toggling the visibility of content when a title is clicked. SimpliJS performs this action with a direct event handler and a simple toggle operation. The code remains short and easy to understand.
Why SimpliJS wins SimpliJS lets developers toggle the dropdown visibility with a single interaction handler. Component frameworks require state variables to control whether the dropdown is visible. SimpliJS avoids that abstraction and focuses directly on the DOM action.
Why SimpliJS wins Form validation can be handled with a straightforward event listener and a few checks. SimpliJS lets developers access form values directly and prevent submission when necessary. The process remains close to standard JavaScript behavior without requiring framework-specific form systems.
Why SimpliJS wins This feature only requires toggling an input field’s type attribute. SimpliJS allows this to be done with a small amount of code and no additional state variables. The logic remains direct and easy to follow.
Why SimpliJS wins SimpliJS handles this interaction with a simple input event listener. The current character count is calculated and displayed immediately. Frameworks typically rely on reactive data binding, which adds complexity for such a basic feature.
Why SimpliJS wins SimpliJS works seamlessly with the native Fetch API. The developer can intercept the form submission, send the request, and process the response without needing a framework-specific networking solution. This keeps the code simple and flexible.
Why SimpliJS wins SimpliJS can implement a simple client-side router using the browser’s hash change event. This avoids installing and configuring external routing libraries, which are often required in major frameworks. For small projects, this approach is faster and easier to manage.
Why SimpliJS wins Switching themes only requires toggling a CSS class on the document body. SimpliJS allows this to be done with a single event handler. Frameworks usually introduce state variables and reactive rendering for the same behavior, which adds unnecessary complexity.
Universal Compatibility SimpliJS's The Bridge (planned for v1.0) will allow you to import components from React, Vue, or Svelte directly into your SimpliJS apps. It's designed to be the ultimate connector for the web ecosystem.
Developer Experience SimpliJS is planning to build Time Travel Debugging directly into the core reactivity engine in version 1.0, enabling instant state sharing and snapshot-based debugging.
Frameworks like React and Svelte rely on heavy compilation or complex Virtual DOM diffing. SimpliJS uses a native Proxy-based reactivity engine. This means no build step is required for production, yet it maintains performance that rivals the leaders.
SimpliJS aims to provide "batteries included" power with "script tag" simplicity. With 8 native features and 7 enterprise plugins, it covers essential use cases without the dependency headache.
