Omarchy (Arch Linux)
The OS I use while building the site. Omarchy gives me an Arch Linux setup tuned for shipping quickly.

Stack
My Vibe Coding Stack ($0)
This is the current stack behind a3.lol. The goal is simple: ship fast, keep the surface area small, and avoid paying for infrastructure before the site actually needs it.
AI Agents
The two options I’d point people to first: Codex as the best paid option, and OpenCode if you want a free setup.
Codex (Paid)
The best paid coding agent option I’ve used. It is the fastest way I know to go from idea to working code when I want strong reasoning, solid edits, and fewer dead ends.
OpenCode (free)
If you want a free option, I put together a video showing how I use Open Code as a practical setup without paying for a premium coding agent.
Free coding agent option with Open CodeWatch
create-t3-app
The codebase foundation. It gives the project the Next.js app router structure, TypeScript setup, env validation, Prisma wiring, and tRPC patterns this site uses.
Supabase
Hosted Postgres for the newsletter data. Prisma connects to the Supabase database, so the app keeps a clean typed server-side data layer without running its own database.
Vercel
Hosting and deployment. It fits this site well because the app is small, static-heavy, and works cleanly with Next.js.
