Website & Web Application Development
Fast, SEO-ready business websites, portals and web applications that you fully own.
Your website is usually the first place a customer decides whether to trust you. AppSage designs and develops business websites, customer portals and custom web applications that load fast, rank on Google and turn visitors into enquiries.
We work with startups that need a first version quickly, and with established companies replacing an old site or building an internal tool. Every project is responsive across phones, tablets and desktops, built with clean code, and handed over with 100% ownership of the source code.

- Laravel
- WordPress
- React

Website & web app development: common questions
How long does a business website take?
A standard 5–10 page business website usually takes 2–4 weeks from approved content and design. Custom web applications are planned in milestones, and you see a working version every one to two weeks.
Will my website be SEO friendly?
Yes. Every site ships with page titles and descriptions, structured data, a sitemap, clean URLs, compressed images and mobile-first layouts, so Google can crawl and understand it from launch.
Do I own the code?
Yes. You receive the full source code and admin access. AppSage never locks you in.
