Frequently Asked Questions About Website Development Companies

What tech stack do website development companies often use?

Website development companies use a wide range of languages, frameworks, tools, and technologies to design and engineer digital solutions. These include: 

  • Front-end development: HTL, CSS, JavaScript, Tailwind, React, Angular, Vue.js 
  • Back-end: Node.js, Python, PHP, Ruby, RESTful APIs, GraphQL 
  • Database: PostgreSQL, MySQL, Microsoft SQL, MongoDB 
  • Cloud: AWS, Azure, Google Cloud Platform 
  • DevOps: Docker, Kubernetes, Git, Jenkins 
  • CMS: WordPress, Drupal, Joomla, Webflow 
  • eCommerce: Shopify, Amazon, WooCommerce, BigCommerce, Adobe Commerce

How are website development companies using AI?

Web application development companies are using AI to improve the software development process, provide better user experiences, and implement advanced features and functions.   

For instance, developer teams are using AI assistants to streamline routine coding tasks, generate documentation, and automate testing. In doing so, they experience up to 50% higher productivity.  

Additionally, custom website development companies may be leveraging AI-driven analytics to identify drop-off points and friction in user journeys. They may also be implementing AI-powered recommendation engines and smarter search features for a more personalized user experience. 

What is the difference between templates and custom website development?

Template websites use pre-built themes and components (e.g., designs, layouts, and features), making it more affordable and faster to build. While these allow some level of customization, it is often limited to the platform or chosen theme. 

Conversely, custom website development tailors the digital solution to client requirements to match brand standards, user journeys, integrations, and performance and security needs. 

Below is a cost-benefit analysis:

How do I evaluate a web development company if I don't have deep expertise in this field myself?

To evaluate a prospective web development company, focus on things you can verify without technical knowledge: visit 2-3 sites they've actually built and test them yourself on your phone for speed and broken links, then call one past client directly (not just read testimonials) to ask if deadlines were kept.

Before signing anything, ask who owns the code and domain when the project ends, and get a written quote listing exact deliverables.
