Features & Capabilities

Preact Developer Tools is a specialized Chrome extension designed to work exclusively with Preact version 10.1.0 and above. It provides developers with a powerful interface to inspect the component hierarchy of their Preact applications directly in the browser. This seamless inspection capability helps developers understand component structure and relationships more clearly.

Additionally, the extension supports live editing of component properties (props) on the fly, allowing developers to test changes quickly without rebuilding or reloading the entire app. This results in faster debugging cycles and more efficient development workflows for Preact-based projects.

Is Preact Developer Tools Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Preact Developer Tools requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Preact Developer Tools is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
