Apollo Client Devtools is a Chrome extension for the open-source GraphQL client, Apollo Client. This extension has 4 main features:
1. A built-in version of the Apollo Studio Explorer that allows you to make queries against your GraphQL server using your app's network interface directly (no configuration necessary).
2. A query watcher that shows you which queries are being watched by the current page, when those queries are loading, and what variables those queries are using.
3. A mutation inspector that displays the mutations made to your Apollo Client application data.
4. A cache inspector that displays your Apollo Client cache data. You can explore the cache through a tree-like interface, and search for specific field keys and values.
Code for this extension can be found at: https://github.com/apollographql/apollo-client-devtools

Works :)
Extension does not work for Apollo Client 3.9.2 . It simply does not see GraphQL. window.__APOLLO_CLIENT__ is present. It's not a bug with GraphQL. connectToDevTools was EXPLICITLY set to true. App is running in dev mod. window.__APOLLO_DEVTOOLS_GLOBAL_HOOK__.ApolloClient IS present. Yes, my client is created within 10 sec of first load. No, waiting for another 10 sec did not help. "An Apollo Client instance was not found, either because an Apollo Client instance was never created, or because it could not be discovered. This is most commonly fixed by setting the connectToDevTools option to true."
DOES NOT WORK ANYMORE. Uncaught runtime errors: ERROR Cannot convert object to primitive value TypeError: Cannot convert object to primitive value I thought it was something wrong with my app. No, its wrong with this plugin.
Straight up doesn't show up in the UI. No sign of it even being installed, other than seeing in my list of extensions.
My mf proj structure stoped working due to this ext, when I tried to switch between pages
Wasted an entire day trying to figure out why my NextJS 13 app was failing in-app redirects. This was the culprit. Once I removed this, it all worked. The error I hit was "TypeError: Cannot convert object to primitive value" when loading some of my pages.
nice
Installed in edge, refreshed the page... and can now see queries, execute them in a useful dev environment. Useful.
Obnoxiously unnecessary. None of the projects I work on would be needed by this extension... but there's no way to prevent it from showing in the console log. (even if I add a filter, it will still display as a message). Why would the chrome developers force a message that isn't critical to the browser? I guess I'll have to start debugging the console in a different browser now.
Mixed response. Sometimes the queries/cache populate, sometimes not. Currently its not working at all
