Before highlighting the top frameworks, let's quickly cover what open source frameworks are and why they've become so popular.
An open source framework is a software library that provides reusable code to facilitate development of applications and services. Frameworks expedite development by providing shared tools for common tasks so devs don't have to reinvent the wheel.
Open source frameworks make their source code publicly available under licenses like MIT, Apache, or GPL. This allows developers to freely use, modify, and distribute the framework as needed. Open source stands in contrast to proprietary, closed-source frameworks with restrictive licenses.
Some examples of popular open source frameworks include React, Angular, and Vue on the front-end, Django and Rails on the back-end, and React Native for mobile development. These frameworks are used by millions of developers worldwide.
There are several key benefits that explain why open source frameworks have taken off:
Overall, open source frameworks empower developers to build better applications faster and cheaper than going it alone. Let's look at 10 top options across the stack.
Here are the 10 most popular open source frameworks spanning front-end, back-end, mobile, and full stack development:
Now let's look at each framework in more detail.
Overview: React is a front-end JavaScript framework created by Facebook focused on building reactive, state-driven UIs. React uses a component-based architecture where UIs are broken into encapsulated components that manage their own state.
Use cases: Building complex, interactive UIs like dashboards and single-page applications. Ideal for frequently updating data flows. Commonly used with Redux and React Router. Major companies using React include Facebook, Netflix, Uber, and Dropbox.
Pros: Great for complex UIs, vibrant ecosystem, extensive documentation, strong community.
Cons: Steep learning curve, setup can be complex, mixing HTML/CSS/JS can get messy.
Overview: Vue is a progressive JavaScript framework for building web user interfaces. It combines ideas from React, Angular, and other frameworks into an approachable core library.
Use cases: Great for SPAs, dashboards, and progressive enhancement of existing sites. Suitable for projects that don't need a full-featured framework. Companies using Vue include Nintendo, GitLab, and Adobe.
Pros: Easy to learn and integrate, well-documented, customizable, good performance.
Cons: Ecosystem not as mature as React or Angular, limited for very complex UIs.
Overview: Angular is a TypeScript-based framework created by Google for building complex, large-scale web applications. It provides complete framework covering the entire web development process.
Use cases: Best for large enterprise web apps with dynamic, real-time features. Extended by Google tools like Firebase. Used by Google, Forbes, and Upwork.
Pros: Full-featured, scalable framework. Helps structure complex applications.
Cons: Steep learning curve. Complex setup and configuration.
Overview: Django is an open source Python framework that follows the model-view-controller (MVC) architectural pattern. It enables rapid development and clean, pragmatic design by providing tools and conventions to handle common web dev tasks.
Use cases: Building content-driven web apps like news sites, content management systems, wikis, etc. that require database integration. Used by Instagram, Spotify, and Dropbox.
Pros: Batteries included philosophy, security, scalability, vast ecosystem of tools and packages.
Cons: Monolithic framework can be complex for smaller apps. Not ideal for real-time applications.
Overview: Ruby on Rails is an open source MVC framework for building full-stack web apps using the Ruby language. It enables rapid app development with an emphasis on simplicity and programmer happiness.
Use cases: Ideal for prototyping and MVPs. Commonly used for web apps like ecommerce sites, social platforms, and SAAS products. Major users include Basecamp, Shopify, and GitHub.
Pros: Great for rapid development. Vibrant ecosystem and community.
Cons: Performance issues at large scale. Monolithic architecture can impede modifying defaults.
Overview: Express is a fast, minimalist web framework for Node.js for building web apps and APIs. It provides a simple interface for working with Node.js HTTP servers to handle routing, templates, and more.
Use cases: Great for APIs, microservices, server-side rendering, and general web apps. Often used with MongoDB or MySQL. Used by IBM, PayPal, and Uber.
Pros: Flexible, unopinionated, excellent performance and scalability
Cons: Minimalist approach means less batteries included, more glue code.
Overview: Laravel is an accessible, open source PHP web framework that follows the model-view-controller (MVC) software design pattern. It is designed for full-stack web development using expressive, elegant syntax.
Use cases: Great for custom CRUD apps, content management systems, ecommerce platforms. Favored for web apps using MySQL/MariaDB and REST APIs. Used by Laracasts, StyleCI, and Slack overlay.
Pros: Expressive syntax, robust features out of the box, scalable.
Cons: Challenging for beginners, requires understanding of advanced PHP features.
Overview: Spring is a robust Java framework for building enterprise-ready business applications. It provides dependency injection to manage Java objects and integrates best practices like layering and declarative transactions.
Use cases: Ideal for data-driven enterprise apps. Used extensively in banking, ecommerce, and healthcare industries. Adopted by Walmart, Netflix, and Amazon.
Pros: Powerful ecosystem, scalable, security, widespread industry adoption.
Cons: High complexity, steep learning curve, heavy focus on enterprise use cases.
Overview: Flask is an open source micro web framework for Python based on Werkzeug and Jinja2. It is designed to keep core simple but extensible so developers can build custom functionalities on top.
Use cases: APIs, web apps, prototyping, ML/AI services, complex workflows. Integrates well with data science tools. Used by LinkedIn, Netflix, and Pinterest.
Pros: Simple, flexible, great documentation, vibrant ecosystem.
Cons: Requires more setup as a microframework, less batteries included.
