Custom Web Applications
A custom web application is software delivered through a browser that does a job specific to your business, rather than presenting information like a website does.
We build the applications businesses run on: SaaS products, internal tools, dashboards, and customer portals. Work starts at the data model and the permissions, because those are the decisions that are expensive to change later, and ends with something deployed, monitored, and documented.
Who this is for
- Teams running critical operations in a spreadsheet that has outgrown itself
- Founders with a validated idea who need the first real version built
- Companies whose off-the-shelf tool cannot express how they actually work
- Businesses needing a customer-facing portal on top of systems they already run
When it's not a fit
- An existing product does the job. Configuring a good SaaS tool beats building one, and we would rather tell you that than take the project.
- The requirements cannot be described yet. Start with a smaller paid discovery rather than an open-ended build.
- You need it in two weeks. Authentication, permissions, and data modelling do not compress well, and cutting them is how projects get rewritten.
- There is no budget for anything after launch. Applications need maintenance in a way that brochure sites do not.
What We Deliver
SaaS Product Development
Multi-tenant applications with authentication, roles, billing, and the admin tooling your team needs on day one.
Internal Tools & Admin Panels
Replacing spreadsheets and manual processes with software that enforces your rules and records who did what.
Dashboards & Reporting
Operational and analytics dashboards built on your real data, with the queries and refresh behaviour thought through.
APIs & Integrations
REST and GraphQL APIs, webhooks, and integrations with the third-party systems your business already depends on.
Auth, Roles & Permissions
Authentication, single sign-on, and role-based access designed up front rather than bolted on after a security review.
Legacy Modernisation
Incremental migration off an ageing application, keeping it running while functionality moves across.
Common Use Cases
- Multi-tenant SaaS products with subscription billing
- Internal operations tools replacing spreadsheet workflows
- Customer and partner portals over existing back-office systems
- Operational dashboards and reporting
- Booking, scheduling, and approval workflows
- Document and asset management with access control
- Incremental migration off a legacy application
Tech Stack
Outcomes you can expect
- A process that used to depend on one person's spreadsheet, running as software
- Permissions that hold up when someone asks who can see what
- A data model that can take the next feature without a rewrite
- Errors you find out about from monitoring rather than from a customer
What you receive
Everything below is handed over to you. Code and infrastructure live in your accounts, not ours.
- The application deployed to your own infrastructure
- Source code in your repositories, with environment setup documented
- A documented data model and migration history
- API documentation for anything another system will call
- Automated tests covering the paths where failure costs money
- Monitoring and error tracking, wired to somewhere you will see it
- Admin tooling so your team can operate the app without database access
Engagement models
Fixed-scope project
A defined deliverable at a fixed price, scoped up front. Best when you know what you need built and want a firm schedule and budget.
Best when: You know what you need built and want a firm budget and date.
Retainer
Ongoing delivery, maintenance, or advisory billed monthly. Best for continuous improvement after launch, or when priorities shift faster than a fixed scope allows.
Best when: The work is continuous and priorities shift faster than a fixed scope allows.
Extended team
Our engineers working inside your team, your process, and your repositories. Best when you have the roadmap but not the capacity or the specific skills.

Frequently asked questions about Custom Web Applications
Software delivered through a browser that does a job specific to your business: a SaaS product, an internal tool, a dashboard, or a customer portal. The distinction from a website is that people use it to do work, not to read about what you do.
Buy, if a product fits how you work with reasonable configuration — you are also buying its maintenance, security patching, and support. Build when the process is a genuine differentiator, or when no tool can express it. We review this before scoping a build, and will say so if buying wins.
Typically Next.js and TypeScript on the frontend, Node.js or Python on the backend, PostgreSQL for data, and Prisma for access. Auth via Clerk or Auth0, Stripe for billing, deployed on Vercel or AWS. We will use your existing stack instead where you have one.
Designed up front, not added later. We model the roles and what each one can see and do before building any features, because retrofitting permissions onto an application that assumed a single user type is one of the most expensive changes you can be asked to make.
Yes. We start with an audit: what it does, what it is built on, what is out of date, and what will break first. That report tells you whether extending it or replacing it is the better spend, and we will recommend replacement if that is the answer.
You do, in your own accounts. We deploy into your infrastructure with the setup defined as code, so you are never dependent on us to deploy, scale, or move it. Handover includes the repositories, environment configuration, deployment pipeline, and runbooks for operating it.
Discovery. We agree the goal, review whatever exists already, and produce a written scope: what will be built, in what order, what you will receive, and what we need from you. It ends with a plan you can approve, amend, or take elsewhere.
The outcome you want and how you will judge it, access to any existing code, designs, hosting, and analytics, one person who can make decisions, and any hard constraints — a fixed launch date, a required stack, compliance obligations. Missing pieces we can work around; an unnamed decision-maker we cannot.
Both. Our published work spans early-stage products and established companies, and our smallest engagements are single fixed-scope projects. What matters is that someone on your side can make decisions and that the problem is defined well enough to scope, not company size.
Yes, as a retainer covering monitoring, security patching, dependency upgrades, performance work, and a monthly allowance for fixes and small changes. You get a report each month showing what was done. It is a separate engagement from the build, so upkeep does not compete with feature work.
Engineering and design work is delivered remotely, so location is not a constraint for those. Our in-person work — hackathons, builder houses, developer meetups, and campus programmes — runs in Delhi, Bangalore, Hyderabad, and Mumbai, plus university campuses across the country.
You get a written summary of what we understood, a proposed scope broken into phases, what each phase delivers, and the engagement model we would recommend. If we think you should buy something off the shelf or not build yet, the summary says that instead.
