Service
Web App Development.
Full-stack web applications built for scale — dashboards, internal tools, SaaS products, and customer portals with clean architecture from day one, not bolted on after launch.
What is custom web app development?
Custom web app development is the design, build and hosting of browser-based software tailored to a specific business workflow, such as a customer portal, internal dashboard, marketplace or SaaS product, instead of adapting off-the-shelf tools. Qodexify builds web apps with React or Next.js frontends and Node.js or Python backends. A typical MVP takes 8–12 weeks and costs roughly $25,000–$60,000.
What's included
Everything from first wireframe to production
Modern frontends
React and Next.js interfaces that stay fast and maintainable as the product grows.
API-first backends
Node and Python services designed around clear contracts, not tangled business logic.
Auth & data security
Role-based access, encrypted data handling, and audit trails built in from the start.
Cloud infra & CI/CD
Automated deploys, monitoring, and rollback plans so launches stay uneventful.
Our approach
How a web app project runs
Map the data model
We define entities, permissions, and integrations before touching UI.
Prototype the core flow
The riskiest user journey gets built first, so we validate early.
Build in vertical slices
Each sprint ships a usable feature end-to-end, not just UI or just backend.
Harden & launch
Load testing, monitoring, and a rollback plan before anything goes live.
Use cases
Web application use cases
Common projects where this service delivers the fastest return.
SaaS products & MVPs
Launch a subscription product with authentication, billing and an admin console, then iterate on real user feedback.
Customer portals
Give customers self-service access to orders, documents, tickets and account data.
Internal tools & dashboards
Replace spreadsheets with role-based tools your team can trust.
Marketplaces & booking platforms
Connect buyers and sellers or schedule appointments with payments and notifications.
Data dashboards & reporting
Turn scattered data sources into live, shareable reporting.
Legacy modernization
Migrate outdated systems to a modern stack with zero-downtime cutover.
Cost & timeline
Typical cost and timeline
Typical ranges based on our past projects. Final pricing depends on scope, integrations, compliance requirements and design complexity.
| Project type | Typical timeline | Typical budget |
|---|---|---|
| Internal tool or dashboard | 4–8 weeks | $15k–$40k |
| SaaS MVP (version 1) | 8–12 weeks | $25k–$60k |
| Customer portal | 6–12 weeks | $30k–$80k |
| Full platform with integrations | 4–6 months | $60k–$150k+ |
Compare options
Custom web app vs. no-code vs. off-the-shelf SaaS
An honest comparison to help you pick the right approach.
| Custom web app | No-code platform | Off-the-shelf SaaS | |
|---|---|---|---|
| Fit to your workflow | Built exactly around your process | Good for simple flows | You adapt to the tool |
| Scalability | Scales with architecture you control | Limits at higher volume and complexity | Vendor-defined limits |
| Ownership | You own code and data model | Locked to the platform | Subscription, no ownership |
| Upfront cost | Highest | Low | Lowest |
| Time to launch | 8–12 weeks for an MVP | Days to weeks | Immediate |

Common questions
About web app projects
How long does a web app typically take?
Most web apps run 6–12 weeks depending on scope, with a usable v1 demoable within the first few weeks.
Can you take over an existing codebase?
Yes — we regularly inherit existing apps. We start with an audit before committing to a scope or timeline.
How much does custom web app development cost?
Most custom web apps cost between $15,000 and $150,000. An internal tool is typically $15k–$40k, a SaaS MVP $25k–$60k and a full platform $60k–$150k or more. We provide a fixed or capped quote after a free scoping call.
Which technology stack do you use for web apps?
Our default stack is React or Next.js with TypeScript on the frontend, Node.js or Python (FastAPI) on the backend and PostgreSQL for data, deployed on AWS or Google Cloud with CI/CD. We choose the stack that your team can hire for and maintain.
Do I own the source code?
Yes. Unless a contract states otherwise, all custom code and deliverables become your property on final payment, and we hand over documentation and deployment runbooks.
Can you build an MVP first and scale later?
Yes. We recommend starting with the smallest version that validates the riskiest assumption, then adding features in vertical slices as usage grows.
