Dynamic Pricing Table Engine

Name: Dynamic Pricing Table Engine
Brand: Grid Theory
Price: 49.00 USD
Availability: InStock

A production-ready TypeScript pricing table engine that transforms static pricing data into interactive, state-driven DOM components with zero dependencies. Built for SaaS companies and e-commerce platforms, this engine handles complex billing calculations entirely on the client side — including flat rates, per-seat pricing, volume tiers, usage-based models, and hybrid configurations — delivering instant UI updates as users interact with sliders and toggles. Unlike typical pricing components that require backend calls for every change, this engine includes a built-in calculation layer for prorating add-ons, applying annual discounts, and computing volume tiers locally, plus a provider-agnostic AI adapter layer that integrates with OpenAI or Anthropic for pricing optimization insights. Ships with a complete white-label theming system via CSS variables, full TypeScript types, and framework-specific integration examples for React, Vue, and vanilla JavaScript.

Guided Quote Builder

Production-ready quote calculator widget that turns website visitors into qualified leads with instant project estimates. This zero-dependency TypeScript solution embeds seamlessly into any website, providing a config-driven wizard that calculates custom pricing based on user selections and captures lead information through a built-in form. Unlike typical contact forms that leave you guessing about budget expectations, this widget pre-qualifies leads by having them self-select project parameters while you capture their contact details alongside their specific requirements and calculated budget range. Built with vanilla TypeScript and a modular engine architecture, the widget compiles to a single JavaScript file with embedded CSS for effortless distribution. The pricing engine supports complex scenarios with base prices, multipliers, and add-ons, while the state machine handles multi-step flows configured entirely through JSON. Custom event dispatching enables integration with any backend, CRM, or automation platform through webhooks. Ship with three pre-configured scenarios (Digital Agency, General Contractor, Wedding Photographer) that demonstrate the full capabilities. The package includes comprehensive documentation for configuration schema, webhook integration, and white-label customization. A built-in SVG icon system with 50+ icons means zero external dependencies while maintaining a professional appearance.

Liquid Cursor Trail

Production-ready fluid physics cursor trail engine that creates stunning liquid effects following user interactions on any website. Unlike typical cursor effects that use basic CSS animations, Liquid Cursor Trail implements a real Navier-Stokes inspired velocity field with curl mechanics to create realistic fluid behavior that responds to cursor speed and direction. Built with pure TypeScript and Canvas 2D, this zero-dependency solution delivers WebGL-quality visuals while maintaining 100% cross-browser compatibility. The engine uses a hybrid architecture combining a low-resolution velocity field (48x48 grid) for physics calculations with a high-performance particle pool (800 particles) for visual rendering. This approach provides the visual fidelity of a full fluid solver while maintaining smooth 60fps performance even on low-end devices. Every aspect is configurable through a simple API — from dissipation rates and curl strength to splat radius and color values. Ship with a single script tag and configuration object. The download includes the minified engine, TypeScript definitions, multi-scenario preview demos (Creative Agency, Luxury Brand, Gaming Studio), comprehensive integration guides for popular platforms, and an AI coding assistant context document. Perfect for agencies and developers who need to add that extra layer of polish to high-impact websites without the complexity of WebGL or Three.js.

Magnetic Text

Production-ready magnetic text animation library that brings interactive typography to life with spring physics — no dependencies, just pure TypeScript performance. Unlike typical text animation libraries that rely on heavy frameworks or CSS-only tricks, Magnetic Text delivers a lightweight physics engine where individual characters, words, or entire text blocks respond to cursor movement with configurable spring dynamics. Built for developers creating memorable web experiences, this library includes TypeScript definitions, touch support, three animation modes (characters/words/blocks), and hardware-accelerated rendering via requestAnimationFrame and translate3d.
