ClusterFuzz is a scalable fuzzing infrastructure which finds security and stability issues in software. It is used by Google for fuzzing the Chrome Browser, and serves as the fuzzing backend for OSS-Fuzz. Fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks. 
 
ClusterFuzz provides many features to seamlessly integrate fuzzing into a software project’s development process. It is highly scalable and automatically files bug, verifies and closes the same from issue tracker.

Vitess is a database clustering system for horizontal scaling of MySQL through generalized sharding. By encapsulating shard-routing logic, Vitess allows application code and database queries to remain agnostic to the distribution of data onto multiple shards. With Vitess, you can even split and merge shards as your needs grow, with an atomic cutover step that takes only a few seconds.
 
Vitess has been a core component of YouTube's database infrastructure since 2011, and has grown to encompass tens of thousands of MySQL nodes.

 Chuck is a simple in-app HTTP inspector for Android OkHttp clients. Chuck intercepts and persists all HTTP requests and responses inside your application, and provides a UI for inspecting their content. Apps using Chuck will display a notification showing a summary of ongoing HTTP activity. Tapping on the notification launches the full Chuck UI. Apps can optionally suppress the notification, and launch the Chuck UI directly from within their own interface. HTTP interactions and their contents can be exported via a share intent.

Gloo is a feature-rich, Kubernetes-native ingress controller, and next-generation API gateway. Gloo is exceptional in its function-level routing; its support for legacy apps, microservices and serverless; its discovery capabilities; its numerous features; and its tight integration with leading open-source projects. Gloo is uniquely designed to support hybrid applications, in which multiple technologies, architectures, protocols, and clouds can coexist.
 
Gloo provides a long list of API gateway features, including rate limiting, circuit breaking, retries, caching, external authentication and authorization, transformation, service-mesh integration, and security.
 
Gloo can route requests directly to functions, which can be a serverless function call (e.g. Lambda, Google Cloud Function, OpenFaaS function, etc.), an API call on a microservice or a legacy service (e.g. a REST API call, OpenAPI operation, XML/SOAP request etc.), or publishing to a message queue (e.g. NATS, AMQP, etc.). This unique ability is what makes Gloo the only API gateway that supports hybrid apps, as well as the only one that does not tie the user to a specific paradigm.
