# Quickstarts

Pick the integration that matches your stack. All paths land at the same place: a verified `id_token` and a logged-in user.

| If you have... | Use this |
|---|---|
| Just a static page or simple PHP site | [HTML only](html.md) |
| A modern SPA (React, Vue, Svelte, vanilla TS) | [JavaScript SDK](js-sdk.md) |
| A PHP backend (Laravel, Symfony, custom) | [PHP SDK](php-sdk.md) |
| Anything else | [OAuth 2.0 from scratch](oauth-from-scratch.md) |
| iOS / Android (preview) | [Mobile](mobile.md) |

Before you start, register a client in the [developer portal](https://app.littlexlittle.org/developers) and copy the `client_id` (and `client_secret` for confidential clients).
