OVERVIEW
Web applications and interactive websites built for real use
Some ideas outgrow a template website: a customer portal, a booking or quoting tool, an internal dashboard, or a marketing site that needs search, motion and personalised journeys. We design and build these as custom web applications, shaped around the tasks your users need to complete.
This website is an example of how we work. It is built with Next.js, React and TypeScript, with light and dark themes, subtle motion that respects reduced-motion settings, instant site search, a protected enquiry form and strict security headers, and it is tested automatically in Chromium, Firefox and WebKit (Safari) browsers on desktop and mobile before release.
Every build includes responsive layouts, accessibility checks, search-friendly page structure and conversion tracking. After launch we host, monitor and improve the application, so you have one accountable partner instead of separate designers, developers and hosting providers.

HOW WE DELIVER
A staged plan. No surprises.
01Discover: Users, goals and success measures
We map who will use the application, the tasks they need to complete, the systems it must connect to and how success will be measured, then agree scope and priorities for the first release.
02Design: Journeys, prototypes and design system
We sketch the key journeys, build clickable prototypes and a design system for colour, type, components and motion, and refine them with your feedback before development starts.
03Build: Iterative development and testing
Features are built in short cycles with regular demos. Automated tests, accessibility checks and security reviews run alongside development rather than at the end.
04Launch: Go live, host and improve
We deploy to production, set up monitoring and backups, redirect old URLs so existing search rankings carry over, and continue with support and improvements.

CUSTOM WEB APPS FAQ
Common questions about Custom web applications & interactive websites.
How much does a custom web application cost?
Cost depends on the number of user roles and screens, integrations, content, design complexity, and hosting and support needs. After a discovery conversation we send a proposal with scope, milestones and commercials, and we can start with a smaller first release.
What is the difference between a website and a web application?
A website mainly presents information. A web application lets people do things, such as sign in, submit and track requests, view dashboards or complete transactions, so it needs data storage, access control and more testing.
Which technologies do you use?
For interactive websites and web applications we typically use Next.js, React and TypeScript, with Tailwind CSS for design systems. For content-led sites WordPress can be the better fit. We recommend a stack after understanding your requirements and who will maintain it.
Will an interactive website still rank well on Google?
It can, when it is built correctly. We render pages on the server, use proper headings, metadata, sitemaps and structured data, and test performance so motion does not hurt search visibility. No one can guarantee rankings, but the technical foundation will not hold you back.
Can you rebuild our website without losing search traffic?
Yes. We map your existing URLs, set up permanent redirects to the new pages and test them before launch, so the rankings and links built up over time carry over to the new site.
Do you build web applications for clients outside Bengaluru?
Yes. Discovery, design reviews and demos run online for clients across India, the UAE and worldwide, with in-person workshops in Bengaluru when they are useful.
