Web Development in Oak Brook, IL

Websites That Work as Hard as You Do

At Xcelacore, we help businesses in Oak Brook and surrounding areas build modern, high-performing websites that actually support growth. Whether you need a new site from scratch or want to rebuild what you already have, we focus on clean, functional design and reliable performance, not trendy fluff that slows you down. Your website is more than just a digital business card. It’s your first impression, your sales team, and your storefront, especially if customers or clients are coming to you online. We make sure it does the job right.

Why Work with Xcelacore for Web Development?

Custom Websites

We don’t use cookie-cutter templates. We design and build websites tailored to your brand, audience, and goals. Whether you’re looking for leads, bookings, or purchases, we ensure your site supports that.

Full-Stack Development

Front-end, back-end, and everything in between—we handle it all. From polished designs to powerful functionality, we create a seamless experience across desktop and mobile.

Scalable and Secure Architecture

We build with growth in mind. Our development process ensures your website is not only secure but also able to scale as your business evolves.

API and System Integration

We connect your website to the tools you already use—CRMs, ERPs, payment systems, or third-party apps—so your data flows where it needs to go.

CMS Integration

Need control over your own content? We work with platforms like WordPress, Drupal, and headless CMS systems, giving you the ability to make updates without needing a developer.

How We Work

Xcelacore follows agile project management (APM) standards for most projects. You and your team will be assigned a dedicated project manager who will oversee the entire project from requirements gathering through execution.

We Start with the Why

What’s the goal of your site? More leads? Better brand image? Faster loading times? We start by understanding what matters most to your business.

We Design with Purpose

User-friendly layouts, modern design, and fast load times, our design team builds with the end user in mind, not just aesthetics.

We Develop and Test

Our developers bring the design to life and test across devices to make sure everything works exactly as it should.

We Support and Improve

Even after launch, we’re here to help with updates, changes, and improvements as your needs shift over time.

Success Stories

We start by understanding business objectives and requirements with technology strategies. Then our work focuses on the implementation of digital technology solutions that drive businesses forward.

“It’s not often that you can work with outside developers, consultants, who truly have your best interests at heart. At every step of the process from architecture to deployment and testing, and at a fraction of the cost of in-house development work has been a dream come true. I can’t speak highly enough of the whole team. Their ability to forecast and deliver on time and within scope is really good. They come with my highest recommendation. These guys are true winners.”

FAQs

Not at all. While we’re based in Oak Brook, we work with clients all over Illinois and the U.S. But if you’re local, we’re happy to meet face-to-face.

We do both. Whether you need a total overhaul or just want to modernize certain parts, we’ll work with what you’ve got—or help you start fresh.

Yes. If that’s important to you, we’ll build the site on a CMS (like WordPress) that lets you make changes easily without needing to code.

We can help with that. While we don’t provide hosting directly, we’ll set everything up and recommend the best options. We also offer ongoing maintenance if you want us to manage updates and security.

It depends on the scope, but most sites take between 4 to 8 weeks from start to finish. We’ll give you a clear timeline before we begin.
