GraphiTab од Jason Simeone

A browser extension that puts a full GraphiQL IDE at your fingertips -- no server setup, no hosted playground, just open a new tab and start querying.

GraphiQL IDE: Create endpoint profiles with custom headers, then launch any profile into an interactive GraphiQL session. Browse the schema with the Explorer plugin to discover types and fields, compose queries visually, and save the ones you want to keep with the Saved Queries plugin so you're not rewriting the same request next sprint.

DevTools Network Inspector: A dedicated Developer Tools panel captures GraphQL traffic in real time. Inspect operation names, headers, request bodies, and responses in a resizable grid. Supports POST, GET, and batched requests, with operation-type filtering and one-click copy-as-cURL for quick reproduction outside the browser.

No ads. No telemetry. No catch. GraphiTab collects zero data about you or your usage, contains no advertisements or donation prompts, and is completely open source.
