A browser extension to inspect Svelte application by extending your browser devtools capabilities

Svelte DevTools

Svelte DevTools is a Chrome extension for the Svelte framework. It allows you to inspect the Svelte state and component hierarchies in the Developer Tools.

After installing you will see a new tab in Developer Tools. This tab displays a tree of Svelte components, HTMLx blocks, and DOM elements that were rendered on the page. By selecting one of the nodes in the tree, you can inspect and edit its current state in the panel to the right.

Requirements

The svelte-devtools extension requires your Svelte application to be compiled with the dev option set to true. If you're using SvelteKit, this is done automatically, outside of that you will need to set it manually.

This extension officially supports Svelte 4.0 and above.
