Built for trainers,
by trainers.
Pokémon Team Builder is the free, open tool we wished existed — fast type analysis, smart coaching, and zero friction. No sign-ups, no data harvesting.
Our Mission
We believe every Pokémon trainer — whether competitive veteran or first-time team builder — deserves tools that are fast, intelligent, and free. Our mission is simple: help you build better teams by understanding <em>why</em> your composition works, not just what the numbers say.
What Makes Us Different
Real-Time Coaching
Most team builders show you data. We explain it. Our Team Coach tells you in plain language why your team has a problem and exactly what to do about it — no competitive jargon required.
Privacy First
Your teams stay on your device. We don't have servers storing your data, we don't track you across the web, and we don't sell information to advertisers. Your browser's localStorage is the only database that matters.
Completely Free
No premium tiers. No paywalled features. No "free trial" that expires. Every feature — from Build Around mode to Showdown export to team comparison — is available to everyone, always.
Works Everywhere
Desktop, tablet, mobile. Light mode, dark mode. Online and offline (via service worker). We support 9 languages and every mainline Pokémon game from Red & Blue to Scarlet & Violet.

The Technology
Pokémon Team Builder is built with modern web technologies for maximum speed and reliability:
- Astro — Static site generation for instant page loads
- Vanilla JavaScript — No heavy frameworks; minimal bundle size
- Service Worker — Full offline support after first visit
- localStorage — Zero-latency data persistence on your device
- PokéAPI — Comprehensive, community-maintained Pokémon data
The result: pages load in under 1.5 seconds, the app works offline, and your teams are always instantly accessible — no loading spinners, no server requests.
Open Source Data
Pokémon game data is powered by PokéAPI, the free, open-source RESTful API for Pokémon data. Sprite artwork is property of Nintendo, Game Freak, and The Pokémon Company. This project is an independent fan creation — not affiliated with or endorsed by the rights holders.
