Empirium

Empirium builds digital infrastructure for operators who need performance, not templates. We started as a two-person studio in Paris, shipping custom sites, SEO systems, and stealth-grade tools for clients who couldn't afford downtime or mediocrity. Today we operate 7 products across AI, privacy, and productivity — all self-hosted, all encrypted by default. We write about what we build: web architecture, technical SEO, browser fingerprinting, AI agents, and operational strategy. No fluff, no corporate speak. Every article on Dev.to comes from production experience, not theory.

Next.js 16, TypeScript, Tailwind CSS, PostgreSQL 16, Drizzle ORM, Auth.js v5, Node.js 22, Cloudflare CDN (HTTP/3), Nginx, PM2, Postfix + OpenDKIM, Sharp, React Email, Playwright. Infrastructure: self-hosted on dedicated VPS (Ubuntu 24.04), zero third-party SaaS dependencies for core ops. AI stack: multi-model routing (Claude, GPT-4, Llama, Mistral), RAG with TF-IDF cosine similarity, voice agents. Stealth stack:
anti-detect browsers, Ed25519 licensing, fingerprint rotation. Everything deployed via rsync + PM2 reload — no CI/CD vendor lock-in.
