WebKitLab Healthcare
A healthcare division that clinics already trust
Before we built for every industry, we built for doctors. Our healthcare division still helps clinics, diagnostic centres and hospitals across West Bengal get found on Google, Maps and AI search, and turn enquiries into appointments, all within medical advertising ethics.
How every project moves
Five stages, in this order, for a chatbot or a full ERP. You see working software every two weeks. Read our approach.
Discover
Process, users and data mapped. Phase one agreed with a fixed price.
Design
Clickable prototypes tested with the people who will use them.
Build
Two week sprints, each ending in a demo you can click through.
Launch
Testing, data migration, training and a planned go live.
Grow
Monitoring, support and new modules as you need them.
Built to be owned, not rented
We would rather earn the next project than lock you into this one. Everything we build is documented, handed over and yours.
You own the code
Source code, data, cloud accounts and app listings in your name, with documentation any developer can follow.
Fixed price for phase one
A clear scope and a fixed fee for the first release, so you know the number before you commit.
Honest about AI
We tell you where AI will pay off and where a simple rule or form is better. Every AI feature is measured on real results.
Questions people ask before starting
What does WebKitLab Technologies do?
WebKitLab Technologies (OPC) Pvt. Ltd. is a software engineering company in New Town, Kolkata. We build AI systems, ERP and management software for schools, colleges, hotels, hospitals, banks and manufacturers, web applications, ecommerce stores and Android and iOS apps. We also run a healthcare marketing division for clinics and hospitals across West Bengal, and we are the parent company of Kito AI, GEO Score Checker, AEO Score Checker and Permitrust LLC.
How much does custom software development cost in Kolkata?
Cost depends on the modules, number of users, integrations and platforms. A focused first release is always far cheaper than a complete system, so we scope a phase one that delivers value on its own, then give you a fixed price for it after a free discovery call.
How long does it take to build a management system or an app?
A first release of a school, hotel or business management system typically goes live in two to four months. Mobile apps usually take two to four months, and AI proof of concepts three to six weeks. We share a week by week plan before work starts.
Do we own the source code?
Yes. Source code, databases, cloud accounts, domains and app store listings are held in your name or transferred to you, as set out in our agreement.
Do you work with clients outside Kolkata and India?
Yes. Our team is in Kolkata and we work with clients across India and overseas. International clients can also engage the group through Permitrust LLC.
Do you still do healthcare marketing?
Yes. Our healthcare division helps doctors, dental clinics, diagnostic centres and hospitals with SEO, AI search visibility, Google Ads, websites and clinic technology, with pages for every major specialty and West Bengal location.
Tell us what you want to build
Share three details. A senior engineer from our Kolkata team will call you, understand the problem and send a written scope with timeline and cost. No obligation, no spam.
- A short call with an engineer, not a salesperson
- A written scope: modules, technology, timeline and fixed cost for phase one
- Honest advice, including when an existing product fits better than custom code
