# Recommended Tech Stacks

Opinionated starting points for projects without an established stack. Existing repository conventions and user preferences take precedence. Verify current compatibility, pricing, and availability before recommending a time-sensitive choice.

## General (All App Types)

| Layer | Tool | URL |

## Mobile App

Native iOS or cross-platform mobile app that lives on a device.

| Layer | Tool | URL |

| Cross-platform framework | Expo | https://expo.dev |
| Native iOS | Xcode | https://developer.apple.com/xcode |

## Full Stack Web App

The "one framework does everything" approach. Next.js can handle frontend, backend, and API routes in a single codebase. Whether this is the simplest choice depends on the project.

## AI App

Any app that uses an LLM or AI image model.

| Layer | Tool | URL |
|-------|------|-----|
| Model API/provider | Choose during project research based on required modalities, cost, privacy, and current availability | |
| Image model/provider | Choose during project research when image generation is required | |

## AI Agent App

An agent where the LLM takes actions in a loop — receives a goal, decides what to do, observes the result, repeats.

**For beginners:** Use Claude Code or Codex as a development agent to prototype and verify the workflow. A deployed agent product still needs an explicit model API/provider and an appropriate runtime or SDK; do not treat the development tool itself as the production runtime.
