Live Build Stack
Full-stack
Design, development, integrations, and launch support.
SEO-first
Built for crawlability, speed, schema, and conversion.
AI-assisted
Live build sessions that compress production cycles.
Flexible
Webflow, WordPress, Shopify, Next.js, React, and more.
Services
Web design and web development services built around business outcomes.
We build sites that can rank, convert, scale, and remain editable after launch. That means design, development, SEO, CMS, analytics, and performance are treated as one system.
Custom Web Development
Front-end, back-end, APIs, CMS architecture, dashboards, custom functionality, and integrations for sites that need more than templates.
Webflow Development
Fast, editable, visually polished Webflow sites with clean CMS structures, reusable components, responsive sections, and scalable page systems.
WordPress Development
Custom WordPress websites, technical SEO, page templates, blog architecture, plugin cleanup, migrations, and maintainable admin workflows.
Shopify & Ecommerce
Conversion-focused storefronts, product pages, custom sections, app integrations, performance improvements, and checkout-path optimization.
AI-Assisted Vibe Coding
Live working sessions where strategy, layout ideas, copy, code, and component prototypes move from concept to usable output faster.
Vibe Coding
Live AI-assisted build sessions that shorten the distance between idea and shipped page.
Traditional website projects move slowly because strategy, design, development, review, and revision happen in disconnected stages. Our live vibe coding sessions compress that cycle.
- Best for homepage redesigns, landing pages, Webflow sections, SaaS page concepts, ecommerce pages, and rapid UX iteration.
- AI speeds up production, but it does not replace senior developer judgment.
- Production code is reviewed, cleaned, tested, and improved before launch.

Development Depth
More than a web design shop.
A modern website has to perform as a sales asset, content engine, technical platform, and brand experience. DEV.co brings web design together with full-stack development, SEO architecture, analytics, integrations, and post-launch optimization.
- UX strategy, responsive design, and reusable design systems.
- CMS structures that your team can actually manage.
- Technical SEO, schema, internal linking, migration support, and Core Web Vitals.
- APIs, CRM integrations, forms, analytics, dashboards, and custom workflows.

Search + Conversion
Built for Google, AI search, and real conversion paths.
Good-looking pages are not enough. Your website needs to be crawlable, structured, fast, internally linked, schema-ready, and designed around the questions your buyers actually ask.
- Search-friendly information architecture and landing page hierarchy.
- Schema, clean HTML, crawlability, indexation, and SEO migration planning.
- AI and LLM visibility through structured, entity-rich content.
- Conversion tracking, form events, analytics, and CRM handoff.
Technology
Built on the right stack for the job.
We do not force every website into one platform. We match the stack to the business case: editing speed, scalability, SEO, performance, maintainability, and long-term ownership.

Designed for desktop, tablet, and mobile from the start.
Your website has to work across every screen. We design responsive systems with clear navigation, concise content, visible CTAs, fast-loading sections, and layouts that preserve the conversion path on mobile.
Process
A cleaner web design and development process.
The goal is not more meetings. The goal is fewer surprises, better communication, faster iteration, and a launch-ready website that can support growth.
Discovery & Strategy
We define goals, audience, offer, navigation, site architecture, technical requirements, and conversion paths.
UX/UI & Content
We map pages, messaging, content hierarchy, wireframes, design systems, and responsive layouts.

We build in Webflow, WordPress, Shopify, Next.js, React, or a custom stack using disciplined AI-assisted workflows.

We test speed, responsiveness, forms, tracking, SEO migration, accessibility basics, and post-launch improvements.

FAQ
Questions buyers ask before hiring a web design and development agency.
Web design defines the visual system, page structure, user experience, brand feel, and conversion paths. Web development turns that strategy into a functional, responsive, fast, editable, and technically sound website.
Yes. Webflow is a strong option for marketing websites, landing pages, CMS-driven content, and teams that want visual editing without relying on developers for every update.
Yes. Live vibe coding sessions are useful for rapid prototyping, layout exploration, page buildouts, UX iteration, and faster collaboration. AI accelerates the workflow, while DEV.co developers review and clean the output before production use.
Sometimes, but it should not be trusted blindly. We use AI to accelerate drafting and prototyping, then rely on human review, refactoring, QA, performance checks, accessibility checks, and technical oversight before launch.
Yes, but it requires planning. URL structure, redirects, metadata, internal links, indexation, page speed, schema, and content hierarchy need to be handled deliberately during the redesign process.
We support Webflow, WordPress, Shopify, Next.js, React, Node.js, Laravel, PHP, HTML, CSS, JavaScript, and custom CMS or API-driven architectures.
Yes. Ongoing support can include design updates, development support, CMS changes, technical SEO, Core Web Vitals work, content additions, CRO improvements, analytics, and bug fixes.
