Choosing
Should you build a web app or a mobile app first?
Start with how people will use the product. A web app suits work done at a desk or a tool shared through a link. A mobile app is a stronger first choice when the camera, location or daily notifications are central to the product. That decision shapes which interactions need the most design work.
For a rich web interface, Next.js and React with TypeScript offer one language across the front and back end. Laravel, Rails or Django suit teams already working in PHP, Ruby or Python. Managed platforms such as Vercel, Supabase and Firebase reduce setup and server upkeep; AWS or Google Cloud offer more control, with more operations work, and can cost less at scale.
For software serving several customers, a shared database is simpler to operate. Separate databases suit enterprise buyers with strict isolation or data-location requirements. We help you decide what belongs in the first version by turning your idea into an agreed feature list.
Local
What Kolkata businesses may need from a web app
Kolkata is a commercial and financial hub for East and Northeast India. A company here managing key work through spreadsheets and inboxes could use a web app with shared data, permissions and a history of that work. Staff get a common place to handle the workflow instead of keeping information in separate files and messages.
The city also has a high-growth information technology sector. A Kolkata firm turning a repeatable service into software needs its working methods captured as workflows, with client logins and subscriptions. An established business launching a digital product may also need the work built without pulling its staff away from their daily responsibilities.
Rules
What an India-focused web app needs to handle
If your product takes payments in India, checkout needs a payment service suited to the transaction. UPI supports person-to-merchant payments, and non-bank services that aggregate customer payments for merchants must be authorised by the RBI. We set up checkout for UPI through an authorised payment aggregator. For subscriptions, we also set up plans, invoices and what happens when a card payment fails, so those cases are part of the billing design.
How it runs
How a web app project runs with us
We are a studio in India working with clients remotely. We use video calls, WhatsApp and shared project boards to discuss the work and keep you involved.
- 01
Discover
We learn what you want the product to do, turn the idea into a feature list and agree what the first version needs. You help us decide which work belongs in that scope.
- 02
Design
We design the flows and screens for onboarding, dashboards and settings. You review how the product will work and give feedback on the screens before moving through the build.
- 03
Build and review
We put each increment on a staging site. You try real tasks there and approve changes before they reach users, giving you a practical way to check the product as it develops.
- 04
Prepare for launch
We set up deployment, error tracking and backups before the product goes live. You can see what has been prepared for release and discuss the launch with us.
Checklist
What to have ready before we talk
Bring what you know about the product and the people who will use it.
- PricingYour view on per-seat, usage-based or flat plans, since it shapes billing and permissions.
- Assets and accessDesigns, prototypes, repositories, the domain, hosting and third-party accounts, with admin access.
- DataThe personal or sensitive information the product will hold, who your customers are and any security reviews they will require.
- Beta usersA small group of target users who could try the product before public launch and identify confusing steps or missing features.
- An existing productIts code and infrastructure, if you want us to review them before deciding what to fix.
Cost & time
What affects the cost and timeline of web app development
The work grows with the rules, data and infrastructure the product needs.
Roles and permissions
Customer-managed teams and invitations add rules to design and test.
Real-time features
Collaborative editing, live dashboards and chat need extra infrastructure and testing.
Large data sets
Imports, exports and reports need background jobs and careful performance work.
Enterprise requirements
Single sign-on, audit logs, data export and security questionnaires add work to the build.
Avoid
Mistakes to avoid when building a web app
Building every account and billing component from scratch
Consider proven services for sign-in, billing and permissions so the budget can go towards the product itself.
Leaving customer separation until later
Design it into the first version of a multi-customer product to avoid a risky rewrite.
Launching without product analytics
Track sign-ups, activation steps and feature use from the first release.
Releasing straight to the live product
Use staging and tested backups so a release or mistake does not immediately become a live incident.
Questions
Asked by businesses in Kolkata
Page updated 5 November 2026
How much will my web app cost?
There is no fixed price for a web app. Cost depends on the integrations you need, how customer workspaces and their data are separated, and the admin tools your team needs. A public API also brings documentation and support work. We agree the scope with you before work begins.
What technology would you use for my product?
We build in TypeScript across the front end, back end, database and APIs. A stack can include Next.js, React, Node.js and PostgreSQL. The choice gives you a way to build a rich interface while using TypeScript across the application; the feature list helps shape the work.
What is included before the app launches?
We set up hosting and monitoring, including deployment, error tracking and backups. Security work starts from the OWASP Top 10, an awareness document covering common web application risks such as broken access control and injection. These are considered as part of preparing the application for use.
Who owns the application and its accounts?
You own the code, repositories, hosting accounts and data. That gives you control of the product assets after the build. The hosting setup also needs a deployment pipeline and transactional email configured to reach inboxes, so the operational accounts are relevant to running the application as well as storing it.
Can you take over an existing app that is struggling?
Yes. We start by reviewing its code and infrastructure, then fix what matters most. If your first version has slow pages or code that is difficult to work with, the review gives us a basis for fixes and a plan before adding more features.
What happens after launch?
We provide ongoing support after setting up the domain, email and analytics at launch. Frameworks, libraries and hosting also need regular updates for security fixes, even when you have no new features planned. You can track activation, retention and churn alongside revenue to see how users engage with the product.
