## What it is
Svelte DevTools is a browser extension for Chrome and Firefox that adds a Svelte inspection tab to browser developer tools. It displays the component tree, HTMLx blocks, and DOM elements of a running Svelte app and lets you inspect and edit component state.

## Use cases
- inspect svelte component hierarchy in devtools
- view and edit svelte component state live
- debug sveltekit application state
- find which svelte component rendered a dom element
- explore htmlx blocks in a svelte app

## When to choose
- you develop apps with Svelte 4+ or SvelteKit and want framework-aware devtools
- you need to inspect or tweak component state without adding logging
- you use Chrome or Firefox 121+ in development mode

## When to avoid
- your app is built with production compilation (dev: false)
- you need devtools for React, Vue, or other frameworks
- you use an older browser version below 121

- artifact type: plugin
- maturity: active
- function: developer-tools
- domain: frontend, web-development, developer-tools
