Best Free Microframeworks of 2024

Flask is a lightweight WSGI framework for web applications. It's easy to use and can scale up to complex applications. It started as a wrapper for Jinja and Werkzeug, and has since grown to be one of the most popular Python web app frameworks. Flask is a suggestion tool that doesn't require any dependencies. The developer can choose the tools and libraries that they prefer. The community has many extensions that make it easy to add new functionality.

Express is a lightweight and flexible Node.js framework that offers a wide range of features for mobile and web applications. It is easy to create a robust API using a variety of HTTP utility methods and middleware. Express offers a thin layer that covers the core web application features without obscuring the Node.js features you already love. Express does not have any notion of a database. Third-party Node modules allow you to interface with almost any database. Express does not recognize 404 responses as errors and will not capture them. This is because a response of 404 indicates that there is no additional work to be done. Express has executed all middleware functions, routes, and found none of them to be responsive.

You can create powerful, scalable apps with minimal overhead and all the functionality you need. Your code is yours. hapi was originally developed to support Walmart's Black Friday sales. It continues to be a trusted choice for enterprise-grade backend requirements. Every line of code that you receive when you install hapi has been validated. You don't have to worry about a deep dependency being neglected or handed to someone untrustworthy. hapi is the only leading framework that doesn't have any code dependencies. hapi needs the most secure settings to manage and control code. This includes 2FA for all contributors. Every component of hapi comes with the most secure defaults. Along with protecting server load through payload limits and timeouts, the hapi block error messages that could leak information. Node Framework's most comprehensive authorization and authentication API.

Express's new web framework Koa was created by the team behind Express. It aims to be a smaller and more expressive web framework that can be used to build web applications and APIs. Koa leverages async functions to eliminate callbacks and improve error handling. Koa doesn't bundle any middleware in its core. It provides an elegant suite that makes writing servers fast and fun. A Koa application is an object that contains a collection of middleware functions. These functions are composed and executed in a stack-like fashion upon request. Koa is similar in design to Ruby's Rack and Connect. However, Koa provides high-level "sugar", at the low-level middleware layer. This increases interoperability and robustness and makes middleware writing much more enjoyable.

A Node.js webservice framework that is optimized for building semantically-correct RESTful web services. It can be used for production use at large scale. Restify optimizes for performance and introspection. It is used in some the largest Node.js deployments. Scale requires that problems are traced back to their source by seperating noise from signal. Restify was built from the ground up with postmortem debugging in view. The project's primary goal is to stay true to the spec. There will be references to RFCs throughout GitHub issues as well as the codebase. Restify is used by some the most well-respected companies in the industry to power some the largest Node.js deployments on the planet Earth. It is the future of Node.js REST Development. It is easy to set up a server. Similar to many other Node. Restify, a js-based REST framework, uses a Sinatra-style syntax to define routes and handlers that serve them.

High-performance, extensible, minimalist Go web framework. Highly optimized HTTP router that uses zero dynamic memory allocation and intelligently prioritizes routes. Build a robust and scalable API that can be easily organized into different groups. Install TLS certificates automatically from Let's Encrypt. HTTP/2 support increases speed and improves user experience. You can choose from a variety of middlewares that are already built-in, or you can define your own. Middleware can either be set at the root, group or route level. Data binding for HTTP payloads, including JSON or XML. API to send a wide variety of HTTP responses including JSON, XML or HTML, as well as file, attachment, stream, blob, inline or blob. Template rendering with any template engine. Customized central HTTP error handling. API that is easily extendable. HTTP router optimized to prioritize routes intelligently. Build robust, scalable RESTful APIs. Extensible middleware framework. Define middleware on a root, group or route level. Data binding for JSON XML and form payload.

It is not easy to develop RESTful web service that support exposing data in a variety representation media types, and abstract away the low level details of client-server communications without a good toolkit. A standard and portable JAX RS API was designed to simplify the development and deployment of RESTful web service clients and services in Java. Jersey RESTful Web Services 3. x Framework is an open source, production-quality framework that supports Jakarta RESTful Web Services 3.0. Jersey framework is much more than JAX-RS's reference implementation. Jersey's API extends JAXRS with new features. GlassFish will continue to track the JAX-RS API, and release regular releases of production-quality reference implementations. APIs are provided to extend Jersey and build a community. It makes it easy to create RESTful Web Services using Java and the Java Virtual Machine.

Rustless provides a REST API micro-framework. It's designed as a simple DSL for developing RESTful APIs easily on top of Iron web framework. It supports common conventions such as multiple formats, subdomain/prefix restrictions, content negotiation and versioning. Rustless is a Ruby port of the Grape library. Hyper, an HTTP library in Rust. Rustless, like Rust, is still in its early stages of development. Don't be surprised if APIs are changed and things break. File an issue or submit pull requests if something isn't working correctly. Rustless was built on Iron which was built on Hyper which is synchronous. Hyper is currently limited and cannot handle many simultaneous connections. This is especially true with keep-alive. It is highly recommended that you use a lightweight asynchronous webserver such as Nginx to serve as a reverse proxy with Rustless.

Welcome to Nancy. Our main inspiration was the Sinatra framework in Ruby, and Nancy was named for the daughter of Frank Sinatra. NancyFx is a project umbrella that contains all components. Nancy is a lightweight framework for building HTTP services using.NET Mono. The framework's goal is to provide a super-duper happy path for all interactions. Nancy has been designed to have sensible defaults. You can go from nothing to a website in just a few minutes with Nancy. Nancy is designed to run anywhere, and we mean that. Nancy was built from the beginning to be independent of existing frameworks. Nancy is built with the.NET Framework client profile and can be used anywhere.
