GrowthBook DevTools

GrowthBook DevTools helps you debug feature flags and experiments and design A/B tests visually — all from your browser.

Features & Capabilities

GrowthBook DevTools is a Chrome extension that lets product teams and developers debug feature flags and run experiments directly in the browser. Use the Visual Editor to create and edit experiments without touching code, instantly view active flags and experiments on any page, override flag values or experiment variations on the fly, and simulate different user attributes to preview experiences.

Key capabilities include detailed evaluation debug logs, on-the-fly variation testing, Archetypes for quick user profiles, and attribute overrides for realistic testing. Requires the GrowthBook SDK (JavaScript, React, or HTML script tag). Learn more in the docs: https://docs.growthbook.io/tools/chrome-extension.

Is GrowthBook DevTools 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.

GrowthBook DevTools requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.
