Vibe Coding Prompt

One line is enough for vibe coding

Paste it into Codex, Claude Code, or Cursor, then add the service you want to build. The agent keeps the frontend, Gencow backend, build, and deploy flow aligned to the same source of truth.

  • Vite + React frontend
  • Gencow backend
  • docs.gencow.com source of truth
  • build and deploy
prompt.txtdocs.gencow.com
Build the frontend with Vite + React and the backend with Gencow (use docs.gencow.com as the source of truth), then build and deploy it.

Brand Story

The world gets better through small improvements

Gencow calls anyone who finds a problem and builds a solution a builder.

A world where anyone can be a builder.

Prompt to Production

The world is not changed only by giant innovations. A tool that solves one person's frustration, a service that removes repetitive work for a team, or a small idea launched for the first time can create meaningful change.

AI has opened an era where more people can build. But turning an idea into a real service still comes with backend, auth, data, and deployment barriers.

Gencow removes those barriers and builds the infrastructure and ecosystem for anyone to create with AI, launch to the world, and improve with users.

Start small

Build the first working version before chasing a perfect plan.

Launch it

Move beyond the idea and let real users meet the service.

Keep improving

Learn from user reactions and grow the product over time.

Why Gencow?

Why Gencow?

An engine purpose-built to create AI app frontends and backends together.

One-Key AI — All Models, One Key

GPT-4o, Claude, Gemini with one API key. No signing up at 3 different sites.

await ai.chat({
  model: "gpt-5.4-mini", // or claude, gemini
  messages: [...]
});

Enterprise PostgreSQL

Local dev boots in 0.1s with PGlite, production auto-switches to PostgreSQL + pgvector. No Docker.

// Local: PGlite (in-memory)
// Production: PostgreSQL + pgvector
// Switch? Automatic.

Security Built-In

Landlock kernel isolation, tenant DB separation, Secrets Vault. Building an insecure SaaS is structurally impossible.

// No auth on function → auto 401
// Tenant DB → fully isolated
// Secrets → encrypted storage

How we compare to the competition
