# Coding agent vs prompt-to-app builder

Prompt-to-app builders generate a prototype inside their own platform; a coding agent works in a folder on your computer, saves real code to your GitHub, deploys to your Vercel, and teaches you how your app works.

| Criterion | Coding agent + our guide | In-browser app builder |
| --- | --- | --- |
| Who owns the code and hosting | You do: standard Next.js code in your GitHub repo and your Vercel account. | Tied to the builder's platform unless you export and migrate it yourself. |
| Initial setup time | ~30 minutes once (Git, Node.js, GitHub, Vercel), guided by your agent. | Immediate in a browser tab. |
| How changes are built | Spec → plan → small steps on a branch → tests and Preview → merge with your OK. | Often one-shot prompts that overwrite working screens when the app grows. |
| Keys and secrets | Blocked from chat and git; stored only in Vercel and `.env.local`. | Depends on the platform; beginners often paste keys into prompts by mistake. |
| What you learn | Repos, branches, specs, databases, environment variables, logs and debugging. | How to prompt that specific platform. |
