Git is a distributed version control system that tracks changes in source code during software development, allowing multiple developers to collaborate on projects while maintaining a complete history of all modifications, branches, and versions.

AsyncAPI is an open-source, protocol-agnostic specification for describing event-driven APIs and message-driven applications. It serves as the OpenAPI of the asynchronous, event-driven world—overlapping with, and often going beyond, what OpenAPI covers.

Kubernetes is an open-source platform for automating deployment, scaling, and management of containerized applications: you define the desired state in a declarative API (Pods, Deployments, Services, etc.), and controllers continuously reconcile reality to match it.

Bruno is an open-source, offline-first API client that stores collections as plain text files directly on your filesystem and uses Git for version control, providing a lightweight alternative to Postman for testing, debugging, and managing APIs while keeping your data local and private.

Backstage is an open-source framework for building developer portals that unifies all your infrastructure tooling, services, and documentation into a centralized software catalog, helping teams manage microservices and ship code quickly while maintaining standards across the organization.

Microcks is an open-source, cloud-native tool that turns API specifications (OpenAPI, AsyncAPI, gRPC, GraphQL, and others) into live mocks in seconds and performs contract conformance testing to verify that API implementations meet their contracts with consumers of each API.

Crossplane is an open-source framework for building cloud-native control planes that extends Kubernetes to orchestrate and manage applications and infrastructure across any cloud provider or environment without needing to write code, allowing platform engineers to create custom APIs that enable self-service infrastructure provisioning with built-in policies and guardrails.

Kgateway is an open-source, Envoy-powered, Kubernetes-native API gateway and ingress controller that implements the Kubernetes Gateway API with its own control plane, letting teams manage north-south and east-west traffic with modern routing, resiliency, and authn/z.

RabbitMQ is an open-source message broker software that implements the Advanced Message Queuing Protocol (AMQP) to accept messages from producers and deliver them to consumers, acting as middleware that enables asynchronous communication between applications by storing messages in queues until they are processed.

Visual Studio Code (VS Code) is a free, open-source code editor developed by Microsoft that provides developers with features like syntax highlighting, intelligent code completion, debugging, version control integration, and extensibility through plugins for writing and editing code across multiple programming languages.

JetBrains is a software development company that creates intelligent development tools and integrated development environments (IDEs) for software developers and project managers, including popular products like IntelliJ IDEA for Java development, PyCharm for Python, WebStorm for JavaScript, and the Kotlin programming language.

Eclipse is a free, open-source integrated development environment (IDE) primarily used for Java development, though it supports multiple programming languages through its extensible plugin architecture, and serves as a platform for building development tools across various domains.
