Mock, validate, and
control your endpoints

Mock before you build

Kusk allows you to define mocked responses on a path level and replace them later on with your upstream. Allowing you to design before you actually build.

Pre-validate your endpoints at the gateway

Kusk helps you validate requests before they arrive at your upstream. You’ll finally send consistent error codes and messages when a request validation fails – across all your microservices.

Control every single path

Analyze request’s, change headers, CORS, limits, QoS and much more – globally – or for every path.

Kusk Team

Watch replay Watch replay

Kusk Gateway uses the ubiquitous OpenAPI spec file as a single source of truth for making an API available to consumers – which includes routing configuration, request validation, timeouts, etc. The team will share more about Kusk Gateway, give a short demo, share what's recently been released and what we have planned on the roadmap.

What Is APIOps? (In Less than 500 Words)

APIOps creates a standardized process and collaborative culture to accelerate how your organization creates APIs and maintains them throughout their life cycle.

User Quotes

What made it click was that I have been trying to use openAPI but without automation the code and the docs go out of sync. Using the docs as part of gitops (APIops?) means they will be the single source of truth. And kusk seems to enable this!
