What does custom web application development cost?

Every project is scoped individually because scope varies enormously — a lightweight internal tool is a very different engagement from a multi-tenant customer portal with Stripe billing and CRM sync. After a free discovery call we produce a detailed specification and a fixed quote so you know the full cost before committing.

Do I need a finished Figma design before we start?

No. If you have designs, great â we’ll build from them pixel-perfect. If you only have wireframes or a rough concept, we include a design sprint in the project scope where we produce production-ready Figma screens before engineering begins.

What tech stack do you use?

Our default stack is Next.js (React) for the front end, Node.js (or Next.js API routes) for the back end, PostgreSQL for the database, and Vercel or Railway for hosting. We’re also comfortable with Remix, Express, Supabase, or PlanetScale â we’ll recommend what fits your requirements and long-term maintenance plan.

Can you integrate with our existing tools — Stripe, HubSpot, our internal API?

Yes. Third-party integrations are a core part of custom web app development for us, not an afterthought. We scope and test integrations against your live accounts — Stripe billing, HubSpot CRM, Salesforce, REST and GraphQL APIs, webhooks, and data pipelines are all things we handle regularly.

Will we own the code at the end?

Completely. All source code is committed to a repository in your Git organization from day one. You own everything — code, database schema, deployment configuration, and documentation. There are no licensing fees, no vendor lock-in, and no ongoing dependency on Figmafy.

How do you handle changes to scope mid-project?

We lock scope in a written specification before we build. If new requirements emerge mid-project, we assess the impact, provide a change-order estimate, and proceed only with your approval. Scope creep doesn’t silently inflate your bill.

Overview

What is custom web application development?

Custom web application development is the process of designing and engineering a web-based software product from scratch — built precisely for your workflows, your data model, and your users. Unlike off-the-shelf tools, a custom web app does exactly what you need it to do, nothing more and nothing less, and it grows with your business rather than constraining it.

At Figmafy, custom web application development starts in Figma — either from designs you already have or from a discovery sprint we run together. We then engineer the full stack: a React or Next.js front end, a Node.js API layer, a Postgres database, role-based auth, third-party integrations, and whatever real-time or data-visualization features your product needs. You get a living, deployable application — not a prototype, not a template — shipped under a fixed scope and a fixed price.

Pixel-perfect

Builds that match your Figma down to the pixel — at every breakpoint.

Fast turnaround

Most projects ship in 3–7 days. Rush options available.

QA tested

Cross-browser, responsive, and accessibility-checked before delivery.

Real developers

Senior engineers, not converters. Dedicated support throughout.

Benefits

Why teams choose our Web Apps service

The advantages of a hand-built Custom Web Applications project, done right the first time.

Built for your exact workflow

Every screen, data model, and permission rule is designed around how your team actually works — not bent to fit a generic SaaS product.

Auth and role-based access

Secure authentication (email, SSO, magic link) and granular role permissions are engineered in from the start — not bolted on later.

Real-time features and live data

WebSocket-powered live updates, real-time dashboards, and instant notifications — so your users always see the current state without a page refresh.

Third-party integrations that actually work

Stripe billing, CRM syncs, REST and GraphQL APIs, webhooks, and data pipelines — integrated cleanly and tested against your real accounts.

Performance-first architecture

Server-side rendering, edge caching, optimized database queries, and lazy-loaded components keep your app fast as data and user counts grow.

Clean, documented code you own

TypeScript throughout, consistent conventions, in-line documentation, and a handover package — so your team can maintain and extend the codebase without us.

What's included

Everything in your build, by default

No upsells for the essentials. Every project ships with the fundamentals done properly.

How it works

How your Web Apps project gets built

A transparent, predictable process with fixed pricing and a dedicated developer at every stage.

01
Share your Figma file
Send us your design link and requirements. We review the file, flag anything ambiguous, and confirm scope — usually the same day.
02
Review & fixed quote
You receive a clear, fixed-price quote and timeline within 24 hours. No hourly surprises, no vague estimates.
03
Development begins
A dedicated developer builds your project pixel-for-pixel, with clean, well-structured code and regular progress updates.
04
Rigorous QA testing
We test every breakpoint, browser, and interaction. Accessibility, performance, and responsiveness are checked before you ever see it.
05
Revisions & feedback
You review a live staging link. We refine until it matches your design exactly — revision rounds are included.
06
Delivery & support
We hand over clean files, deploy if needed, and stay available for post-launch support. Your project is yours to own.

Timeline

A clear path to delivery

1
Discovery & architecture
Week 1
We audit your Figma, map your data model and user roles, define the API contract, and lock a fixed scope document before a single line of code is written.
2
Core build
Weeks 2–5
Front end and back end are built in parallel sprints — components, API endpoints, database schema, auth, and integrations — with a staging environment updated continuously.
3
Integrations & QA
Week 6
Third-party services are wired up and tested against live credentials, then the full app passes cross-browser, performance, and security QA.
4
Review, polish & handover
Week 7
You review the staging build and request revisions. We apply final polish, deploy to production, and hand over the codebase, environment variables, and documentation.

Deliverables

What you receive

Deployed, production-ready web application
Full codebase in your Git repository (TypeScript, documented)
Database schema, migrations, and environment setup guide
Admin access and all third-party service credentials documented
30-day post-launch support window

Who it's for

Built for the way you work

Our Custom Web Applications service fits a range of teams and goals.

Ops and product teams

Your team has outgrown spreadsheets and Notion hacks. You need a purpose-built internal tool — with your data, your permissions, and your logic — that people will actually use.

B2B SaaS founders

You have Figma designs for a customer-facing portal or dashboard and need a full-stack engineering team that can ship it on schedule, under a fixed budget.

Agencies with client mandates

White-label custom web application development for your end clients — we build to your Figma files, you deliver under your brand.

Why Figmafy

The right partner for Custom Web Applications

Design-first, engineering-second

We start in Figma, not in a code editor â so every screen is validated against your design before we build it, and nothing ships that doesn’t match.

True full-stack ownership

One team owns the front end, the API, the database, and the infrastructure — no coordination gap between a UI contractor and a back-end freelancer.

Fixed scope, no surprises

We scope every project to a detailed specification before work begins. You know exactly what you’re getting, when you’re getting it, and what it costs.
