Features & Capabilities

Apollo Client Devtools is a powerful Firefox add-on designed for developers using Apollo Client, the popular open-source GraphQL client. It enhances your development workflow by providing four key features: a built-in GraphQL explorer to run queries seamlessly via your app's network interface, a query watcher to monitor active queries and their variables, a mutation inspector to track all mutations affecting your application data, and a cache inspector featuring a tree-like interface for exploring and searching Apollo Client's cache data. This tool simplifies debugging and helps you maintain efficient GraphQL operations within your applications.

You can access the source code on GitHub and report any issues directly through the project's issue tracker. To dive deeper into Apollo's ecosystem and capabilities, visit Apollo GraphQL's official website.

User Reviews

Users find Apollo Client Devtools valuable for Apollo GraphQL debugging when it works correctly, requiring configuration with 'connectToDevTools: true'. However, many report the add-on is unreliable on Firefox and LinuxMint, with issues like failure to connect, missing developer tools tab, freezing, and disappearing functionality. Some suspect the Firefox support is weaker compared to Chromium. When operational, it is appreciated; otherwise, it causes frustration due to instability and lack of clear integration.

Pros

Useful for developers working with Apollo GraphQL when it functions properly.
Works well if configured correctly, specifically by adding 'connectToDevTools: true' in ApolloClient settings.
Helpful for debugging Apollo queries within browser developer tools.

Cons

Frequently does not work or fails to connect, especially on LinuxMint and Firefox.
Often causes the developer tools tab to not appear or disappear without explanation.
Freezes or stops updating, requiring removal and reinstallation to fix.
No clear visibility or indication in Firefox extensions or developer tools, unlike in Chromium browsers.

Is Apollo Client 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.

Apollo Client Devtools requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Medium ****** ** ********* ****** ********* *** **** ****** **** **** ** ******* ** ********** **** ***********

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.

Apollo Client Devtools is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
