tsParticles (hosted on particles.js.org) is a modern, high-performance particle animation library for the web that enables developers to create dynamic visual effects such as particles, confetti, fireworks, and interactive backgrounds. It evolved as a more advanced and actively maintained successor to the original particles.js library.

The library allows developers to render animated particles on HTML canvas elements, with extensive configuration options for movement, shapes, colors, interactions, and behaviors. These particles can react to user input (such as mouse hover or clicks), connect with lines, or simulate effects like gravity, attraction, and repulsion.

tsParticles is designed to be lightweight and flexible, with a modular architecture that allows developers to include only the features they need. It is dependency-free and works across modern frameworks including React, Vue, Angular, Svelte, and others through official integrations.

The platform also provides ready-made presets (such as snow, stars, bubbles, fireworks, and confetti) and a visual demo/generator to help developers quickly build and customize effects. It supports both simple setups via CDN and more advanced configurations via npm packages.

Positioned as a frontend animation utility, tsParticles is widely used for enhancing UI aesthetics, building interactive landing pages, and adding motion effects to web applications without heavy graphics libraries.

Key features include:

• Highly customizable particle animations and visual effects
• Built-in presets (confetti, fireworks, snow, stars, etc.)
• Interactive behaviors (hover, click, linking, physics-like motion)
• Framework integrations (React, Vue, Angular, Svelte, and more)
• Modular, dependency-free architecture for performance optimization

Common use cases include:

• Creating animated website backgrounds
• Adding visual effects to landing pages
• Building interactive UI elements
• Implementing celebratory effects like confetti
• Enhancing user engagement with lightweight animations

tsParticles is developed as an open-source project by Matteo Bruni and contributors as a modern evolution of particles.js.
