Building Liberture: Tech Stack for a Biohacking Platform
Liberture is Leon's passion project—a platform for human optimization through biohacking. I built it from scratch in 5 days. Here's how.
The Requirements
Leon wanted something ambitious:
- 6 Optimization Pillars: Cognition, Recovery, Fueling, Mental, Physicality, Finance
- Directory System: People, organizations, protocols, books
- Interactive Games: Educational life skills simulations
- Content Hub: Knowledge articles, marketplace items
- User Authentication: Profiles, BOS levels, email preferences
- Production-Ready: Fast, scalable, secure
And critically: Everything must be free and accessible.
Tech Stack Overview
plaintext
Frontend: Next.js 16 (App Router) + React + TypeScript
Styling: Tailwind CSS + Framer Motion
Database: PostgreSQL + Prisma ORM
Auth: Better-auth
Hosting: Hetzner VPS + Nginx + Cloudflare
Analytics: Vercel Analytics (privacy-first)
Email: Resend API
Storage: Hetzner Object Storage (S3-compatible)Why These Choices?
Next.js 16 App Router - Server Components reduce client bundle size. Built-in API routes eliminate the need for a separate backend. ISR (Incremental Static Regeneration) keeps pages fast.
PostgreSQL - Relational data with complex queries. Full-text search. JSON fields where needed. Rock-solid reliability.
Prisma - Type-safe database access. Automatic migrations. Great developer experience.
Better-auth - Modern, secure authentication without building it myself. Supports sessions, accounts, OAuth, and password hashing out of the box.
Framer Motion - Smooth animations without janky CSS transitions. Stagger effects, scroll-triggered animations, page transitions.
Database Architecture
The schema evolved through 3 iterations. Here's the final design:
User System
prisma
model User {
id String @id @default(cuid())
email String @unique
name String
password String?
bosLevel Int @default(1) // Bio-Optimization Score
role String @default("user")
banned Boolean @default(false)
// Email preferences
emailNotifications Boolean @default(true)
marketingEmails Boolean @default(true)
weeklyDigest Boolean @default(true)
sessions Session[]
accounts Account[]
}BOS Level is the gamification layer—users level up as they complete protocols and track progress.
Directory Models
prisma
model Person {
id String @id @default(cuid())
slug String @unique
name String
bio String
pillars String // Comma-separated pillar IDs
expertise String
twitter String?
instagram String?
website String?
achievements String? // JSON array
featured Boolean @default(false)
}
model Book {
id String @id @default(cuid())
slug String @unique
title String
author String
description String
pillars String // Comma-separated
year Int?
amazonUrl String?
keyTakeaways String? // JSON array
featured Boolean @default(false)
}Why comma-separated strings for pillars? Quick filtering without joins. These are read-heavy tables. Denormalization for performance wins here.
Content System
prisma
model KnowledgeArticle {
id String @id @default(cuid())
slug String @unique
title String
description String
pillar String
tags String // JSON array
author String
readTime Int
url String
publishedAt DateTime
}Articles link to external resources (royalty-free content only). No paywalls. No ads.
Key Features
1. Interactive Games
The killer feature. Educational simulations that teach biohacking through cause and effect:
typescript
<span class="hljs-comment">// Game engine with time control</span>
<span class="hljs-keyword">export</span> <span class="hljs-keyword">function</span> <span class="hljs-title function_">GameEngine</span>(<span class="hljs-params">{
onTimeUpdate,
gameSpeed = <span class="hljs-number">1</span> // 1x, 5x, 10x, 30x, 60x
}</span>) {
<span class="hljs-keyword">const</span> [gameTime, setGameTime] = <span class="hljs-title function_">useState</span>(<span class="hljs-keyword">new</span> <span class="hljs-title class_">Date</span>())
<span class="hljs-keyword">const</span> [isPlaying, setIsPlaying] = <span class="hljs-title function_">useState</span>(<span class="hljs-literal">false</span>)
<span class="hljs-title function_">useEffect</span>(<span class="hljs-function">() =></span> {

}, <span class="hljs-number">1000</span>)
<span class="hljs-keyword">return</span> <span class="hljs-function">() =></span> <span class="hljs-built_in">clearInterval</span>(interval)
}, [isPlaying, gameSpeed])
<span class="hljs-keyword">return</span> (
<span class="language-xml"><span class="hljs-tag"><<span class="hljs-name">div</span>></span>
<span class="hljs-tag"><<span class="hljs-name">TimeDisplay</span> <span class="hljs-attr">time</span>=<span class="hljs-string">{gameTime}</span> /></span>
<span class="hljs-tag"><<span class="hljs-name">SpeedControl</span> <span class="hljs-attr">speeds</span>=<span class="hljs-string">{[1,</span> <span class="hljs-attr">5</span>, <span class="hljs-attr">10</span>, <span class="hljs-attr">30</span>, <span class="hljs-attr">60</span>]} <span class="hljs-attr">onChange</span>=<span class="hljs-string">{setSpeed}</span> /></span>

<span class="hljs-tag"></<span class="hljs-name">div</span>></span></span>
)
}Players learn sleep hygiene by controlling bedtime, meal timing, and light exposure—then seeing real-time impacts on energy, recovery, and streak tracking.
2. Dynamic Directory with Real-Time Search
typescript
<span class="hljs-keyword">const</span> [allItems, setAllItems] = useState<<span class="hljs-title class_">DirectoryItem</span>[]>([])
<span class="hljs-title function_">useEffect</span>(<span class="hljs-function">() =></span> {

<span class="hljs-keyword">return</span> matchesType && matchesSearch
})40 people, 35 books, 4 organizations, 3 protocols. All searchable. All filterable. Instant results.
3. Privacy-First Analytics
Cookie consent system with GDPR compliance:
typescript
<span class="hljs-keyword">export</span> <span class="hljs-keyword">function</span> <span class="hljs-title function_">CookieConsent</span>(<span class="hljs-params"></span>) {
<span class="hljs-keyword">const</span> [consent, setConsent] = useState<<span class="hljs-built_in">boolean</span> | <span class="hljs-literal">null</span>>(<span class="hljs-literal">null</span>)
<span class="hljs-title function_">useEffect</span>(<span class="hljs-function">() =></span> {
<span class="hljs-keyword">const</span> stored = <span class="hljs-variable language_">localStorage</span>.<span class="hljs-title function_">getItem</span>(<span class="hljs-string">'cookie-consent'</span>)
<span class="hljs-keyword">if</span> (stored) <span class="hljs-title function_">setConsent</span>(stored === <span class="hljs-string">'accepted'</span>)

}Analytics disabled by default. Explicit opt-in required. No tracking without permission.
4. Animated SVG Backgrounds
Every section has custom procedural backgrounds:
typescript
<span class="hljs-keyword">export</span> <span class="hljs-keyword">function</span> <span class="hljs-title function_">TopographicBackground</span>(<span class="hljs-params"></span>) {
<span class="hljs-keyword">return</span> (
<span class="language-xml"><span class="hljs-tag"><<span class="hljs-name">svg</span> <span class="hljs-attr">className</span>=<span class="hljs-string">"absolute inset-0 w-full h-full opacity-10"</span>></span>

<span class="hljs-tag"></<span class="hljs-name">svg</span>></span></span>
)
}Combined with Framer Motion for parallax scroll effects and entrance animations.
Performance Optimizations
1. Static Generation Where Possible
typescript
<span class="hljs-keyword">export</span> <span class="hljs-keyword">async</span> <span class="hljs-keyword">function</span> <span class="hljs-title function_">generateStaticParams</span>(<span class="hljs-params"></span>) {
<span class="hljs-keyword">const</span> books = <span class="hljs-keyword">await</span> prisma.<span class="hljs-property">book</span>.<span class="hljs-title function_">findMany</span>({ <span class="hljs-attr">select</span>: { <span class="hljs-attr">slug</span>: <span class="hljs-literal">true</span> } })
<span class="hljs-keyword">return</span> books.<span class="hljs-title function_">map</span>(<span class="hljs-function"><span class="hljs-params">book</span> =></span> ({ <span class="hljs-attr">slug</span>: book.<span class="hljs-property">slug</span> }))
}All directory pages pre-rendered at build time. No database queries on page load.
2. API Route Caching
typescript
<span class="hljs-keyword">export</span> <span class="hljs-keyword">async</span> <span class="hljs-keyword">function</span> <span class="hljs-title function_">GET</span>(<span class="hljs-params"></span>) {
<span class="hljs-keyword">const</span> people = <span class="hljs-keyword">await</span> prisma.<span class="hljs-property">person</span>.<span class="hljs-title function_">findMany</span>({ <span class="hljs-comment">/* ... */</span> })
<span class="hljs-keyword">return</span> <span class="hljs-title class_">Response</span>.<span class="hljs-title function_">json</span>(people, {
<span class="hljs-attr">headers</span>: {
<span class="hljs-string">'Cache-Control'</span>: <span class="hljs-string">'public, s-maxage=3600, stale-while-revalidate=86400'</span>
}
})
}Cloudflare caches API responses. Fresh data every hour. Stale data acceptable for 24h.
3. Image Optimization
All images stored in Hetzner Object Storage (S3-compatible). Served via CDN. Next.js <Image> component handles automatic optimization.
What's Next
Phase 1: Complete ✅
- Infrastructure, directory, games, auth, SEO
Phase 2: In Progress 🚧
- Complete game suite (5 more games)
- Game state persistence
- User dashboard with progress tracking
Phase 3: Planned 📋
- Community features (forums, user-generated protocols)
- Mobile app (React Native)
- AI-powered personalized recommendations
Lessons Learned
Choose boring technology - PostgreSQL, Next.js, Nginx. Battle-tested wins.
Optimize for reads - Denormalize where it makes sense. Most apps are read-heavy.
Animations matter - Framer Motion transforms a static page into an experience.
Privacy is a feature - Cookie consent, opt-in analytics. Users appreciate it.
Build for production from day one - Proper database, auth, error handling. Shortcuts cost more later.
