What's the tech stack? With 484 tools, does the app feel heavy or slow to load?

With 484 tools, performance was a top engineering priority from day one. Here's how it stays fast: ⚡

The Tech Stack:

• ⚛️ React 19 — latest React with performance improvements

• 📘 TypeScript 5.9 — type safety across the entire codebase

• ⚡ Vite 7 — blazing fast build pipeline and hot module replacement

• 📱 Capacitor 8 — native Android packaging

• 🏪 Zustand — lightweight state management (51 stores, all optimized)

• 🧪 201 automated tests — keeping everything stable

Why It Stays Fast:

• 🔀 Code splitting — tools load on demand, not all 484 at once

• 🖥️ Client-side processing — no server round-trips for tool execution

• 💾 PWA caching — assets cached locally after first load

• 📦 Optimized bundles — Vite tree-shakes unused code

• 🏎️ Smart search is instant — searches through tool metadata, not DOM elements

In practice, the app loads fast, searches feel instant, and individual tools execute without any perceptible delay. The 484-tool count is a content number — it doesn't mean 484 tools are loaded into memory.

"484 tools, one fast app. We count the tools, not the loading spinners." 🏎️
