Web development questions, answered straight.
Still got questions? Our team replies to every enquiry inside 24 hours.
What does a web development agency do?
A web development agency builds the engineering behind your website or app: front-end code, back-end logic, databases, CMS setup, API integrations and performance. A senior team like Whitehat ships custom web development that loads under 2.5 seconds, meets WCAG 2.2 AA accessibility, and is benchmarked against your previous site at 60 days post-launch.
What's the difference between web design and web development?
Web design covers the look, feel and user experience — layout, branding, wireframes and conversion strategy. Web development is the engineering that turns those designs into a working, fast, secure site or app: code, databases, integrations and performance. We keep both under one roof so they never fall out of sync. See our sister web design service for the design-led view.
What technologies do your web developers use?
Our web developers build with React, Next.js, Astro, Node and TypeScript for custom work; Shopify and Shopify Plus for commerce; WordPress and WooCommerce for content-led sites; and Webflow for marketing builds. For headless and Jamstack we pair a Next.js or Astro front-end with Sanity, Contentful or Storyblok. We pick the stack that fits your scale and your team, not our preference.
Can you build a custom web application, not just a website?
Yes — custom web application development is core to what we do. We build customer portals, booking and quoting systems, internal dashboards and SaaS products. We scope the data model, design the architecture, build the app, and wire up authentication, user roles, billing and reporting. Every application ships with documentation and tests so your team can extend it.
Can you integrate our site with our CRM, ERP and payment tools?
Yes — API integrations are part of most builds. We routinely connect sites and apps to CRMs (HubSpot, Salesforce), ERPs and accounting (Xero, NetSuite), payment gateways (Stripe, PayPal) and marketing platforms (Mailchimp, Klaviyo). We map your stack during discovery so leads, orders and data sync automatically in real time — no manual re-keying between systems.
How much does web development cost?
Marketing-site development scales with page count, integrations and complexity. eCommerce and headless builds run $40k–$200k+. Custom web applications are scoped individually. We quote fixed-price after a discovery sprint, so there are no surprise invoices. Smaller fixes and feature work are available on a monthly dev retainer.
Do you work with our existing design or dev team?
Yes. We routinely build from a designer's Figma files, ship through in-house dev teams, and partner with other agencies. We provide briefs, QA tickets and clear acceptance criteria, and we write clean, documented, standards-compliant code so your team can review, merge and maintain it. We can lead the whole build or slot in as your engineering pod.
How do you make sites load in under 2.5 seconds?
Performance is engineered in from day one, not bolted on. We use code-splitting, server and edge rendering, image and font optimisation, critical CSS and CDN caching, then measure Core Web Vitals before launch. The result averages 2.1s mobile LCP and a 92+ Lighthouse score across the 47 sites we shipped in 2025 — faster sites rank, convert and retain better.
Do you offer web development packages for small businesses?
Yes. We scope right-sized web development packages for small business, from an affordable starter build to bespoke custom development as you grow. Rather than a fixed price list, we quote fixed-scope after a short discovery so you only pay for what moves the number — and every build hits the same sub-2.5s standard that lifts conversion 187% on average on our rebuilds.
Everything else we run in-house.
