One of the most common questions we get at Adeocode is: "How long does it actually take to build a custom web app?"
Our answer: 8 weeks — and we've refined this process across hundreds of projects since 2017.
Here's exactly how we structure it.
Week 1–2: Discovery & Architecture
Before writing a single line of code, we align on goals, user flows, and technical requirements. We map out the database schema, define the tech stack, and produce a clickable prototype. This phase prevents the most common cause of blown timelines: scope creep from unclear requirements.
Stack we typically use:
- Frontend: React or Next.js
- Backend: Node.js or Python (FastAPI)
- Database: PostgreSQL
- Hosting: AWS or Vercel
Week 3–4: Core Build
With architecture locked in, we sprint through the core features. By end of Week 4, clients have a working prototype they can actually click through — not a static mockup, but a real, deployed application.
Week 5–6: Feature Completion & Integrations
This is where the polish happens. Third-party integrations (Stripe, Auth0, SendGrid, AI APIs), admin dashboards, and secondary features get built out. We also begin internal QA.
Week 7: QA & Performance
Every endpoint gets tested. We run Lighthouse audits, fix accessibility issues, and optimize database queries. Nothing ships slow.
Week 8: Launch & Handoff
We handle DNS configuration, SSL, monitoring setup (Datadog or Sentry), and deploy to production. We hand off full documentation and source code.
Why This Works
The 8-week constraint forces prioritization. Most failed software projects don't fail from lack of features — they fail from too many features built in the wrong order.
By shipping a production-ready MVP in Week 8, clients can validate with real users before investing in a V2.
