How to choose a website design company in Sri Lanka
Most website design companies in Sri Lanka show similar portfolios and quote similar starting prices, so compare them on what happens after the first mock-up. Ask who writes and enters the content, how the site performs on a low-cost Android phone over mobile data, whether technical SEO is set up at launch, who owns the domain, hosting and source code, and what support costs after the first year. A written proposal that answers those questions is worth more than a lower headline price.
Design that works on Sri Lankan phones
Layouts tested on mid-range Android devices and slower connections, with Sinhala and Tamil content handled properly where you need it.
Development you can maintain
Modern frameworks or a familiar CMS, chosen for your team, with documentation, admin training and full ownership of the code and accounts.
Found on Google from launch
Technical SEO, structured data, fast loading and a sitemap are part of every build, so the site can rank for your services and location.
Choosing a web developer in Sri Lanka
A useful proposal should make the scope, content responsibilities, integrations, acceptance criteria, hosting and post-launch support clear. Our hiring guide explains how to compare a freelancer, development company or in-house hire without judging the decision on price alone.
Website projects for overseas businesses
Businesses in Australia, the United States and elsewhere can discuss a remote website project with our Sri Lankan development team. Before development starts, we agree on the website scope, content responsibilities, integrations, review milestones and post-launch support. Communication times and project costs are confirmed in the proposal; working remotely does not require a local office in your country.
Frequently Asked Questions
What is custom web development?
Custom web development involves creating websites that are tailored specifically to meet the unique needs and objectives of a business. Unlike template-based solutions, custom web development provides greater flexibility, scalability, and the ability to integrate specific functionalities and features.
How long does it take to develop a website?
The development timeline for a website depends on its complexity and features. On average, a custom website can take anywhere from 6 to 12 weeks to develop. For a more accurate estimate, please contact us with your project details.
What is responsive web design?
Responsive web design ensures that your website looks and functions well on all devices, including desktops, tablets, and smartphones. It involves creating a flexible layout that adjusts seamlessly to different screen sizes and resolutions, providing a consistent user experience across all devices.
Do you offer website maintenance and support?
Yes, we provide ongoing website maintenance and support services to ensure your site remains secure, up-to-date, and performs optimally. Our services include regular updates, security checks, and performance optimization.
Are you a website design company or a web development company?
Both. App Dev designs the look and structure of the site and builds it, so there is no hand-off between a design agency and a separate developer. For larger projects we also work alongside your in-house designer or marketing team.
How much does a website design company in Sri Lanka charge?
Our packages start from LKR 80,000 for a five-page business website and scale with pages, custom features, e-commerce and multilingual content. The web design price guide lists what each package includes so you can compare quotations fairly.
What platforms do you use for CMS development?
We develop custom CMS solutions and work with popular platforms like WordPress, Joomla, and Drupal. Our goal is to provide you with a content management system that is easy to use and allows you to manage your website content efficiently.
