Everything you need to debug
your GraphQL traffic.

// The problem

Every GraphQL request hits the same URL. DevTools doesn't know what you're looking at.

Nothing leaves your browser.
Ever.

Captured requests live in memory, scoped to the active tab. No background sync, no analytics, no auth tokens shipped to a server. We can't see your traffic — by design.

// FAQ

Questions, answered.

Does it require a config file or schema? +
No. The extension reads operation names directly from the request body. It works with any GraphQL endpoint as long as the URL contains /graphql and the POST body has a query field.
What about subscriptions over WebSockets? +
Yes — graphql-transport-ws and graphql-ws connections are captured as subscriptions, with the event count visible in the row preview.
Does it work on localhost? +
Yes. Any port, any protocol, any local domain. localhost:4000/graphql works the same as production.
Will my auth tokens be sent anywhere? +
No. The extension makes zero outbound network calls. Everything you see in the sidepanel stays in your browser's memory, scoped to the tab it came from.
What permissions does it need, and why? +
webRequest to observe network traffic, sidePanel for the UI, and <all_urls> read-only — needed because we don't know which domain your endpoint lives on.
How much does it cost? +
Free. No tier, no paywall, no account required. If that changes, existing installs stay free.
