Why Choose a Top Custom Web App Development Agency
A generic agency ships templates. A top agency ships custom code that scales to 100,000 users.
IRPR has shipped over 200 custom web applications. Each one is built from scratch using Next.js, React, Node.js, or Python. We do not use page builders or drag-and-drop tools. Every line of code is written by a senior engineer with 8+ years of experience.
Our clients come from 50+ countries and include funded startups, mid-market companies, and Fortune 500 teams. We deliver in 8-12 weeks with a fixed price. No scope creep, no surprise invoices. You own the full codebase from day one.
How We Compare to Other Agencies
Not all custom web app development agencies deliver the same outcome. Here is the difference.
Many agencies use hourly billing, junior developers, and pre-built templates. They quote low but charge for every change. IRPR works differently.
We assign senior engineers only, give you a fixed price, and ship your code to your own GitHub repo. No lock-in, no hidden fees.
- Hourly billing with no cap
- Junior developers with 1-2 years experience

- Code stays on their servers
- Scope creep costs extra
- No compliance expertise
- Fixed price from the Roadmap phase
- Senior engineers with 8+ years experience
- Custom code in Next.js, React, Node.js, Python
- Code in your repo from day one
- No scope creep - we define scope upfront
- HIPAA, PCI-DSS, SOC 2 compliance built in
Our 4-Phase Custom Web App Development Process
From idea to production in 8-12 weeks. Each phase has a clear deliverable.
Phase 1 is the Idea validation call. We listen to your problem and confirm fit in 30 minutes. Phase 2 is the Roadmap - a 1-week sprint that produces a detailed plan, wireframes, and a fixed price.
Phase 3 is Product build. Our engineers code your web app in 6-10 weeks using Next.js or React on the frontend and Node.js or Python on the backend. Phase 4 is Release - we deploy to AWS, set up monitoring with Sentry and New Relic, and hand over the keys.
What Ships with Every Custom Web App
Every project includes these deliverables by default. No add-ons, no upselling.
We believe in full transparency. Every deliverable is listed in the Roadmap and included in the fixed price.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and monitoring
- New Relic performance monitoring
- AWS or Vercel production deployment
- PostgreSQL database with automated backups
- API documentation (Swagger or Postman)
- Admin dashboard for managing users and data
