QLoo
The Codeless GraphQL Engine

What is QLoo?

QLoo is a GraphQL Server built on top of Gloo and the Envoy Proxy.

QLoo leverages Gloo's function registry and Envoy's advanced HTTP routing features to provide a GraphQL frontend for REST/gRPC applications and serverless functions. QLoo routes requests to data sources via Envoy, leveraging Envoy HTTP filters for security, load balancing, and more.

Thanks

QLoo would not be possible without the valuable open-source work of projects in the community. We would like to extend a special thank-you to Envoy and gqlgen server library.
