The 6 Best Web Design Agencies in Seoul

Saleswell suits Korean small and mid-sized companies that want a business website planned around how they sell. The studio in Guro's digital business district has built company websites since 2019, working through a fixed process of business analysis, agreeing a direction, custom planning and an optimised build. Each project gets an interface designed for that client rather than a stock layout. Renewals of older websites and optimisation work are offered as separate services, and the website is in Korean.

The Cream Union suits large companies that need a website or digital platform designed and then run over time. The Gangnam agency has worked as a digital creative company since 2004, covering brand experience, UX and UI design, campaigns, content and the ongoing operation of sites. Its project list includes work for Lotte, AIA and KB Securities. It also develops its own AI products, and its website is available in Korean and English.

Web Design Korea suits small businesses in Yongsan and Itaewon that want one supplier for a website, an online shop and hosting. The studio works from an office on Itaewon-ro, and its listed services cover website design, e-commerce stores, web hosting and marketing. Keeping the site and the hosting together means a single contact when something needs fixing. Ask to see recent projects, including any bilingual sites, before agreeing the scope.

DFY suits brands that want a website or app planned as part of a wider digital strategy. The agency describes itself as a full-service digital marketing agency, and its work spans UX and UI design, digital products and platforms, branding and digital campaigns. Web accessibility appears among its services, which matters for public bodies and large companies with compliance requirements. Its main office is on Gangnam-daero 140-gil, with further spaces in Seongsu-dong and Paju.

Asiance suits premium brands that need a Korean website or online store built and then marketed by the same agency. Its customer experience team develops websites, apps, e-commerce sites and event booking systems, and builds custom AI tools. Strategy and market research come first, and advertising, social media and performance campaigns can follow once the site is live. The Jeong-dong office works with Kakao, Naver and Salesforce, and the agency's website is in English, Korean and Japanese.

MNCS Korea suits multinational companies that want their Korean website built and then promoted with the same data. Alongside its marketing work, the Cheongdam-dong agency offers web design and development, app development and content management system integration. Translation and localisation turn a global site into a Korean one, and SEO and SEM for Google and local search engines help it get found. The agency works with Kleinlab, and its website and company profile are in English and Korean.
