How long does web application development take?

8–14 weeks for a focused tool or portal; 14–24 weeks for a typical business platform; 6+ months for enterprise scope. Working software is visible on staging from week two either way.

Which technology should our web app use?

For most US businesses: React/Next.js + Node.js or Python + PostgreSQL on AWS — mainstream, fast, and easy to hire for later. But the honest answer depends on your integrations, team, and constraints, which is what discovery determines. Comparisons: [React vs Angular vs Vue](/compare/react-vs-angular-vs-vue/), [Node.js vs Python](/compare/nodejs-vs-python/).

Can a web app work offline / on phones?

Yes — responsive design is standard, and where field conditions demand it we build offline-tolerant PWAs with sync. If you need store distribution or deep hardware access, that's [mobile app development](/services/mobile-app-development/).

Can you integrate with our existing systems (QuickBooks, Salesforce, our ERP)?

Yes — integrations are half the value of most builds. We connect via official APIs, and where none exist, we've handled EDI, SFTP drops, and (reluctantly, reliably) screen-scraping. See [API development & integration](/services/api-development/).

Can you rebuild our old web application?

Yes — modernization is a core service. We extract the business rules that took you a decade to refine and re-platform them without a big-bang rewrite, usually via the [strangler-fig approach](/resources/architecture/strangler-fig-legacy-replacement/).

Who hosts the application?

Your cloud account, set up by us with infrastructure-as-code — you hold the keys from day one. Typical hosting runs $100–$1,500/month depending on scale.

Do you provide ongoing support?

Yes — SLA-backed [maintenance plans](/services/software-maintenance-support/) with monitoring, patching, and a standing improvement backlog.

Web Application Development Company

Web applications are where most business software should live in 2026: your field team's phone, your customer's laptop, and your office desktops all run the same version, and shipping an improvement takes a deploy — not an IT rollout. If that's the destination, this page covers what we build, how, and for how much. Shortcut: free estimate in 24 hours.

[ OUR WEB APPLICATION · 01 ]

Frontend: React with Next.js as the default — server-side rendering for speed and SEO, a component model that scales, and the largest hiring pool if you ever bring development in-house. Angular or Vue where your team's context favors them. Backend: Node.js for API-centric and real-time systems; Python/Django where data science and AI features live close to the product; .NET or Java in enterprise environments that standardize on them. Data & cloud: PostgreSQL as the default database (boring, bulletproof, free); AWS or Azure with infrastructure-as-code so your environment is reproducible, not artisanal. AI layer: where it earns its place — RAG search over your documents, AI agents for workflow steps, LLM features via OpenAI or Claude. See AI application development. Every stack choice is documented with a written rationale. If you've been told you need microservices for a 40-user internal tool, get a second opinion — ours is free: monolith vs microservices.

[ PROCESS · 02 ]

Process

**Discovery (1–3 weeks)** — workflows mapped, integrations audited, prototype built, fixed quote issued.

**Design** — UX tested with the people who'll actually use it; sign-off before code.

**Sprint development** — staging URL from week two; demo every sprint; you reprioritize between sprints.

**Hardening** — automated tests, load tests at your projected concurrency, OWASP security review, UAT.

**Launch** — rehearsed data migration, staged rollout, rollback plan, training.

**Run** — monitoring, SLA support, quarterly roadmap. [Maintenance plans](/services/software-maintenance-support/).

[ PERFORMANCE, SECURITY, ACCESSIBILITY · 03 ]

Performance, Security, Accessibility — By Default

**Speed:** Core Web Vitals budgets enforced in CI; slow software is abandoned software.

**Security:** OWASP Top 10 review, role-based access control, encrypted data at rest/in transit, SSO ([SAML/OIDC](/resources/how-to/how-to-set-up-sso-for-your-saas-product/)) where your org needs it.

**Accessibility:** WCAG 2.2 AA-aligned builds — legally prudent and simply larger-market correct.

**Compliance:** HIPAA, SOC 2, and PCI-scoped builds delivered with controls designed into the architecture. [Certification links.]

[ COST · 06 ]

Cost

Simple portals and dashboards: $25K–$60K. Standard business web applications: $60K–$150K. Complex platforms (multi-tenant, regulated, heavily integrated): $150K–$500K+. What moves the number: integration count, user roles/permission complexity, real-time features, and compliance scope. Full breakdown with examples: web application development cost.

A website presents information; a web application does work — it has logged-in users, data they create and change, and workflows it executes. Marketing site: web development. Software in the browser: this page.
