An advanced armor set and charm skill calculator for Monster Hunter Portable 3rd (PSP).
MHP3 Armor Set Search is a client-side tool that finds every armor set that activates the skills you want. Pick your skill targets, optional charms, weapon slots and hunter type, and the built-in search engine enumerates all viable combinations — with decorations, charm/table names, materials, defense and resistance breakdowns.
- Complete MHP3rd data — all armor pieces (Blademaster/Gunner, both genders), decorations, skill trees and charms, including Torso Up piercing pieces.
- Skill target search — select any skill (or several) and get every set that reaches the required point thresholds, including activated and negative skills.
- Save file import — upload your
Save.BINand the app decrypts the PSP/Game save and imports all of your charms automatically. - Hypothetical charm search — find what's possible even without owning the charm:
1 skill,2 skills, orslottedcharm modes. - Flexible constraints — weapon slots, gender, max rarity, max HR / village stars, and Torso Up toggles.
- Decorations & materials — decorations are applied automatically and every result lists the required craft materials.
- Most-searched sets — anonymous, aggregated leaderboard of the most popular searches (persisted in Upstash Redis).
- Search history — your past searches are saved locally so you can re-run them instantly.
- Export as image — render any result set to a PNG to share with friends.
- Live analytics — visitors and page views tracked with Vercel Web Analytics and Speed Insights.
The app is deployed and live on Vercel:
Badges below are generated on the fly from the Vercel Web Analytics API and update automatically:
| Metric | Badge |
|---|---|
| Visitors (last 30 days) | |
| Page views (last 30 days) |  |
The raw data is also available as JSON at /api/analytics.
- SvelteKit — full-stack framework
- Svelte 5 — runes-based reactivity
- Tailwind CSS — styling
- Upstash Redis — top-sets leaderboard + analytics cache
- Vercel Analytics & Speed Insights — traffic and performance monitoring
- TypeScript — type-safe data model
- Prettier & ESLint — code quality
- Node.js 20+ and npm

For the analytics badges to show real numbers you must configure these environment variables in Vercel:
| Variable | Description |
|---|---|
VERCEL_TOKEN |
A Vercel API token with Web Analytics read access |
VERCEL_PROJECT_ID |
The Vercel project identifier (prj_…) |
VERCEL_TEAM_ID |
(optional) The team identifier, only if the project belongs to a team |
The badges fall back to a neutral “—” value when these are missing, so the site still works without them.
