Opzo

Opzo is a lightweight, open-source web framework designed for building modern web applications with simplicity and performance in mind. It is written in TypeScript and is built on top of the Fastify web framework, leveraging its speed and low overhead. The framework emphasizes minimalism, providing developers with essential tools without unnecessary abstractions, making it ideal for projects where efficiency and clarity are prioritized.

One of the key features of Opzo is its modular architecture, allowing developers to include only the components they need. This modularity extends to its routing system, middleware, and plugin ecosystem, which can be customized to fit specific project requirements. Opzo also integrates seamlessly with modern JavaScript and TypeScript tooling, offering strong typing support and first-class TypeScript compatibility.

Opzo is particularly well-suited for APIs, microservices, and server-side rendering applications. Its performance is comparable to Fastify, as it inherits much of its underlying infrastructure, including its high-speed JSON handling and efficient request/response cycle. The framework also includes built-in support for WebSocket connections, making it versatile for real-time applications.

The Opzo community is relatively small but active, with contributions coming from developers who value simplicity and performance. Documentation is concise and focused on practical usage, with examples provided for common use cases. While Opzo may lack some of the higher-level abstractions found in larger frameworks, its straightforward design appeals to developers who prefer a hands-on approach to web development.

Opzo is distributed under an open-source license, allowing for free use, modification, and distribution. It is available on GitHub and can be installed via npm or yarn. The project continues to evolve, with updates focused on stability, performance improvements, and expanded plugin support.
