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.
The Infection Monkey is an open source security tool for testing a data center's resiliency to perimeter breaches and internal server infection. The Monkey uses various methods to self propagate across a data center and reports success to a centralized Monkey Island server.
skor is a utility for Postgres which calls a webhook with row changes as JSON whenever an INSERT, UPDATE or DELETE event occurs on a particular table. You can drop the docker image next to your Postgres database instance and configure a webhook that will be called.
It works using a pg_notify trigger function and a tiny C program skor that listens to the notifications and calls the configured webhook with a JSON payload.

A collective list of free APIs for use in web development.
A WebGL accelerated, browser based JavaScript library for training and deploying ML models. Use flexible and intuitive APIs to build and train models from scratch using the low-level JavaScript linear algebra library or the high-level layers API. Use TensorFlow.js model converters to run pre-existing TensorFlow models right in the browser. Retrain pre-existing ML models using sensor data connected to the browser, or other client-side data.
migra is a schema comparison tool for PostgreSQL.
It's a command line tool, and Python library. Find differences in database schemas as easily as running a diff on two text files.
Migra makes schema changes almost automatic. Management of database migration deployments becomes much easier, faster, and more reliable.
PostgreSQL schema documentation tool
Pleroma is a federated social networking platform, compatible with GNU social and other OStatus implementations. It is free software licensed under the AGPLv3. It actually consists of two components: a backend, named simply Pleroma, and a user-facing frontend, named Pleroma-FE.
