Service

We rapidly develop custom web applications that fit your business needs.

• We transform diverse business processes into web applications: customer management, approvals and workflows, reservations, search, data management, and more.
• We handle admin dashboards, authentication and authorization, notifications, payments, and API integrations with external services.
• Using Supabase, Cloudflare, SendGrid, and other technologies, we move quickly from prototype to full-scale development.

We design and develop web applications that fill gaps in existing SaaS solutions and align with your unique workflows, prioritizing clarity for end users.
Even when requirements aren't finalized, we create prototypes you can interact with to refine features. We build applications that start small, validate through testing, and grow sustainably as you operate.

Build
websites that are easy to update, fast, and secure.

• We select and build headless CMSs—including microCMS, Kuroco, KARTE, NILTO, and Contentful—tailored to your goals and operational structure.
• We support content migration from WordPress and legacy CMSs, as well as redesign of update workflows.
• We provide end-to-end support for infrastructure moves—from Vercel to Cloudflare—and API integration with marketing automation tools and third-party services.

Headless CMS combined with modern frontends like Astro and Next.js deliver both content agility and fast performance. Security hardening with Cloudflare and infrastructure optimization create maintainable, scalable websites.
We handle new builds, phased migration of existing sites, and shared platform architecture for multiple projects.

Websites that users can actually use with confidence.

• We provide accessibility audits and improvements based on WCAG 2.2 and JIS X 8341-3.
• We thoroughly validate usability through keyboard navigation and screen reader testing.
• We support VPAT and ACR creation for international markets, AA conformance achievement, and certification.

IAAP-certified WAS specialists review the design, implementation, and architecture of websites and applications. We diagnose items that automated checks cannot identify through careful manual review. Beyond creating investigation reports, we provide improvement recommendations, implement fixes, and conduct post-launch re-validation — supporting you every step of the way to build websites that adapt to individual user needs.

From feasibility verification to
high-quality frontend implementation.

• We implement frontends for complex APIs using React and Vue (including frameworks).
• We provide everything from specification definition and feasibility assessment to front-end test applications.
• We build flexible team structures, from partial participation to long-term projects.

We serve as your frontend implementation partner for design firms and system integrators, handling everything from design and specification-based implementation to complex API and headless CMS integration. Whether you need partial development support, technical verification only, or team participation in long-term projects, we adapt flexibly to your project scope and structure.

Transform complex workflows into clear, intuitive interfaces.

• We analyze the purpose, users, and workflows of your website or web application to design optimal UI/UX.
• We create Figma prototypes to quickly validate interaction patterns and screen flows.
• We establish design systems and style guides that are easy to maintain and update.

We consider not just visual beauty, but also information discoverability, usability, and implementation ease. Our team, experienced in frontend implementation, creates user-centered UI/UX design for everything from websites to business applications.
We also handle UI improvements and redesigns of existing services, pre-development prototyping, and preparation of Figma assets for handoff to operations teams.

We provide flexible technical expertise to solve even non-standardized web challenges.

• We plan and develop web services and AI content leveraging LLM and generative AI APIs.
• We also support migration from Vercel to Cloudflare, cookie consent management (GDPR), security measures, and more.
• We flexibly support legacy system improvements, technical research, and partial implementation or markup work.

From adopting cutting-edge web technologies to renovating long-running systems, we propose the optimal approach based on broad technical expertise and development experience. Starting from the stage of "we're unsure if it's feasible" or "we don't know which technology to choose," we conduct PoCs and feasibility studies to quickly turn implementation methods into concrete plans.
