Web Frameworks Technologies & Software

A web framework provides the structure, tools, and libraries developers use to build web applications without starting from scratch. It handles common tasks — routing URLs, connecting to databases, processing forms, and managing user sessions. We track 4 web framework technologies at TechnologyChecker.io covering over 850,000 active domains. The category spans server-side frameworks across multiple programming languages: C# (ASP.NET), JavaScript (Express), Ruby (Rails), and PHP (Laravel).

ASP.NET leads with 26.19% market share and 512,821 active domains — nearly 3x its closest competitor. Express (Node.js) is second at 7.15% with about 140,000 domains. Ruby on Rails holds 4.6% with 90,157 domains, and Laravel takes 4.16% with 81,463 domains. ASP.NET's dominance reflects decades of Microsoft enterprise adoption. Notable ASP.NET customers include Accenture, Deloitte, IBM, Bank of America, and Siemens.

Yes. ASP.NET grew from 12,010 domains in 2011 to a peak of 515,680 in December 2024. It holds 26.2% market share — the largest in the web frameworks category — and powers enterprise applications at companies like HSBC, Oracle, FedEx, and Johnson & Johnson. Microsoft's continued investment in ASP.NET Core and .NET 8/9 ensures modern features and cross-platform support. Our data shows 19,000 companies migrated from ASP.NET 4.0 to current versions, confirming active platform renewal.

Express is a minimalist Node.js framework — lightweight, unopinionated, and ideal for APIs and real-time applications. Ruby on Rails and Laravel are full-stack, opinionated frameworks that emphasize convention over configuration. Rails (Ruby) pioneered this approach; Laravel (PHP) adapted it for the PHP ecosystem. In our data, Express has 169,570 companies, Rails has 90,157 domains, and Laravel has 81,463. Express suits JavaScript-first teams, Rails suits rapid prototyping, and Laravel suits PHP-heavy organizations.

All four frameworks we track are free and open-source. ASP.NET Core uses the MIT license, Express uses MIT, Ruby on Rails uses MIT, and Laravel uses MIT. You pay nothing for the framework itself. Costs come from hosting, infrastructure, and optional paid services. Laravel offers paid tools like Forge ($12/month) and Cloud (from $0 usage-based). ASP.NET pairs with Azure (paid). Express and Rails typically run on Linux VPS hosting starting at $5-20/month.

Express is the easiest entry point if you already know JavaScript — it's minimal, with few conventions to learn. Laravel is beginner-friendly for PHP developers, with clear documentation and a large tutorial ecosystem. Ruby on Rails has strong conventions that guide new developers but requires learning Ruby first. ASP.NET has the steepest learning curve due to C# static typing and the .NET ecosystem's complexity. Pick the framework that matches the language you already know.

Notable companies running Ruby on Rails include Capgemini, Siemens, Bank of America, Oracle, IBM, PwC, HCLTech, Wells Fargo, and DHL. We track 90,157 active Rails domains with a 4.6% market share. The framework has strong adoption in IT consulting, financial services, and professional services. Companies founded in the 2010s make up about 40% of the Rails customer base, with a significant enterprise segment from pre-2000 organizations.

Yes, with caveats. Express handles high-concurrency applications well thanks to Node.js's non-blocking I/O model. Companies like Accenture, IBM, Deloitte, Siemens, and Samsung use it in production. At 169,570 tracked companies and 7.15% market share, it's the second-most-adopted framework in our data. The trade-off is that Express is unopinionated — you choose your own ORM, authentication, and project structure. Large teams need clear conventions to avoid architectural drift.

It depends on what you're building. No-code tools (Webflow, Bubble) work for marketing sites, landing pages, and simple CRUD apps. Web frameworks are necessary for custom business logic, APIs, real-time features, and applications that need to scale. The 850,000+ domains running on just these four frameworks show that most serious web applications still require code. If your project needs custom authentication, complex data processing, or third-party API integrations, a framework is the better investment.

Yes, but the patterns differ by framework. ASP.NET shows strong internal consolidation: 19,000 companies migrated from ASP.NET 4.0 to current versions, while only 2,341 left for Express. Laravel gains from ASP.NET (6,643 companies switched over) but loses to Express (3,323 departures). Ruby on Rails sees the most outflow to Express, reflecting the broader industry shift toward JavaScript-first stacks. The trend is modernization within ecosystems, not wholesale platform abandonment.
