WunderQL is a cross-platform desktop application used for testing GraphQL API performance. Developed under tech accelerator OSLabs, WunderQL was created with the developer in mind. We wanted a simple, no fuss developer tool that allows the user to measure the performance of their GraphQL server throughout the development life cycle. You can measure the response time of your GraphQL queries, simulate a production environment with load testing, and search your past queries to see if there was any degradation in performance over time.
