# Why Thulite?

Thulite is a web framework built for speed, security, and SEO, powered by Hugo and npm. It helps you create content-driven websites, including blogs, marketing sites, documentation portals, and e-commerce projects, with production-ready defaults from day one.

If you need a site that loads quickly, stays secure, and ranks well, Thulite gives you a strong starting point.

## Features

Thulite is an all-in-one framework for modern websites. It includes the essentials out of the box, plus a growing ecosystem of [integrations](https://thulite.io/integrations/) and [templates](https://thulite.io/templates/) to match your use case.

Some highlights include:

- [Site generator](https://gohugo.io/): Use Hugo for fast builds and flexible content modeling.
- [Dependencies](/start-here/concepts/dependencies/): Manage project dependencies explicitly with npm.
- [Integrations](https://thulite.io/integrations/): Extend your project with integrations such as CSS frameworks, SEO optimization, and image handling.
- [Templates](https://thulite.io/templates/): Start from purpose-built templates for docs, blogs, landing pages, and more.

## Design Principles

These five design principles explain why Thulite exists, which problems it solves, and when it is the right fit for your team.

Thulite is...

- [Solid architecture](#solid-architecture): Build sites that are maintainable and scalable over time.
- [Fast by default](#fast-by-default): Avoid performance regressions by starting from optimized defaults.
- [Maximum secure](#maximum-secure): Keep your site aligned with current web security best practices.
- [Easy to use](#easy-to-use): You don't need to be an expert to build something with Thulite.
- [Developer-focused](#developer-focused): Get the tooling, docs, and community support needed to ship confidently.

### Solid architecture

Thulite applies ideas from [The Twelve-Factor App](https://12factor.net/) to promote maintainable architecture and reliable deployments. These principles encourage clear configuration, clean dependency management, and portable environments.

The result is a project structure that scales from simple sites to larger multi-environment setups without becoming fragile.

### Fast by default

Performance matters for every website, but it is especially important for content-heavy experiences. Slow pages reduce engagement, conversions, and trust. Real-world studies consistently show measurable business impact from faster load times:

- 43% faster LCP → 156% more conversions ([Ray-Ban](https://web.dev/case-studies/rayban-speculation-rules/), 2025)
- 42% faster LCP → 60% more visit-to-order conversions ([T-Mobile](https://web.dev/case-studies/t-mobile-case-study/), 2025)
- 18% faster load time → 8.9% more user engagement ([Monrif Publishing](https://web.dev/case-studies/monrif-cwv/), 2025)
- Performance improvements → 27% growth in lead generation ([Fotocasa](https://web.dev/case-studies/fotocasa-cwv/), 2025)

Many frameworks make it easy to build pages that feel fast on a developer laptop but become slow in production, especially on mid-range mobile devices.

Thulite combines architectural discipline with production-oriented optimizations and tools such as [Quicklink](https://getquick.link/). Our goal is simple: make it hard to accidentally ship a slow site.

### Maximum secure

Security incidents are common: service outages, defaced homepages, leaked credentials, and exposed payment data. The impact is technical, financial, and reputational.

Website security is the practice of protecting systems against unauthorized access, modification, disruption, and data loss.

Effective protection requires decisions across the full stack: application code, server configuration, authentication policies, and client-side behavior.

Thulite helps by combining [MDN's web security guidelines](https://infosec.mozilla.org/guidelines/web_security) with sensible defaults, so your baseline stays aligned with modern standards.

### Easy to use

Thulite aims to be accessible to every web developer. It is designed to feel familiar, whether you are building your first static site or migrating from another stack.

The framework removes unnecessary complexity during onboarding. You can start with basic HTML and CSS, then adopt advanced features incrementally as your project grows.

### Developer-focused

Thulite succeeds only if developers enjoy working with it. That is why the project invests heavily in usability, documentation, and long-term maintainability.

From a solid CLI experience to actively maintained documentation, the focus is on helping teams move from setup to shipping with less friction.
