Conductor is an orchestration engine that runs in the cloud.
Netflix built Conductor to help orchestrate microservices based process flows with the following features:
Allow creating complex process / business flows in which individual task is implemented by a microservice.
A JSON DSL based blueprint defines the execution flow.
Provide visibility and traceability into the these process flows.
Expose control semantics around pause, resume, restart, etc allowing for better devops experience.
Allow greater reuse of existing microservices providing an easier path for onboarding.
User interface to visualize the process flows.
Ability to synchronously process all the tasks when needed.
Ability to scale millions of concurrently running process flows.
Backed by a queuing service abstracted from the clients.
Be able to operate on HTTP or other transports e.g. gRPC.
Crunch is a tool for lossy PNG image file optimization. It combines selective bit depth, color type, and color palette reduction with zopfli DEFLATE compression algorithm encoding using the pngquant and zopflipng PNG optimization tools.
Nuster is a high performance caching proxy server based on HAProxy. It is 100% compatible with HAProxy, and takes full advantage of the ACL functionality of HAProxy to provide fine-grained caching policy based on the content of request, response or server status.

mountebank is the first open source tool to provide cross-platform, multi-protocol test doubles over the wire. Simply point your application under test to mountebank instead of the real dependency, and test like you would with traditional stubs and mocks.
A template for PostgreSQL High Availability with ZooKeeper, etcd, or Consul.
BackstopJS automates visual regression testing of your responsive web UI by comparing DOM screenshots over time.
Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in microservice architectures. It manages both the collection and lookup of this data. Zipkin’s design is based on the Google Dapper paper.
Applications are instrumented to report timing data to Zipkin. The Zipkin UI also presents a Dependency diagram showing how many traced requests went through each application. If you are troubleshooting latency problems or errors, you can filter or sort all traces based on the application, length of trace, annotation, or timestamp. Once you select a trace, you can see the percentage of the total trace time each span takes which allows you to identify the problem application.
Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber Technologies. It is used for monitoring and troubleshooting microservices-based distributed systems, including:
Distributed context propagation
Distributed transaction monitoring
Root cause analysis
Service dependency analysis
Performance / latency optimization
Falcor is the innovative data platform that powers the Netflix UIs. Falcor allows you to model all your backend data as a single Virtual JSON object on your Node server. On the client you work with your remote JSON object using familiar JavaScript operations like get, set, and call. If you know your data, you know your API.
Falcor is middleware. It is not a replacement for your application server, database, or MVC framework. Instead Falcor can be used to optimize communication between the layers of a new or existing application.
Cilium is open source software for providing and transparently securing network connectivity and loadbalancing between application workloads such as application containers or processes. Cilium operates at Layer 3/4 to provide traditional networking and security services as well as Layer 7 to protect and secure use of modern application protocols such as HTTP, gRPC and Kafka. Cilium is integrated into common orchestration frameworks such as Kubernetes and Mesos.
