Kabushiki Kaisha gini is a web production and development company based in Osaka, positioned as a team specializing in Jamstack. It is not a developer SaaS product that you can sign up for and use directly in the traditional sense; instead, it provides custom development services for corporate clients, covering websites, Headless CMS, web applications, mobile apps, and LINE mini apps.
Based on the site content, gini’s main focus is Jamstack website development. It can handle corporate sites, brand sites, service sites, web media, and rebuilds of existing websites. Its service scope covers requirements definition, technology selection, site design, UI design, front-end development, CMS design and implementation, infrastructure setup, data migration, testing and launch, and operational improvements. The stated technology stack includes Next.js, Astro.js, React, Vue.js, Flutter, microCMS, Contentful, Headless WordPress, AWS, Vercel, Cloudflare, and more. The company publicly highlights its official partnerships with microCMS and Contentful, and can also handle more complex requirements such as API integrations, access control, log design, and membership features.
The website does not publish standard packages; pricing is project-based. Consultation and proposals are free, and the inquiry form lists budget ranges from under 300,000 yen to over 10 million yen, suggesting that the company can cover both smaller implementations and mid-to-large projects. The production process is relatively clear, including consultation, interviews and proposals, contract signing, information architecture, design, development, and launch.
Its strengths are its focused positioning, making it suitable for companies that want to migrate from WordPress to Jamstack, adopt a Headless CMS, improve Core Web Vitals, or bring in external experts for technology selection. It also publishes a substantial amount of technical blog content and downloadable materials, with documentation-style content that is relatively strong among web production companies. The downsides are that it is not an out-of-the-box tool, and both cost and timeline depend on the project. Details such as source code delivery, self-hosting terms, SLA, and payment methods are not disclosed. Its service focus is also clearly centered on the Japanese market.
It is suitable for companies that lack Jamstack/Headless CMS experience but want a modern front-end architecture and one-stop delivery. Chinese clients considering cooperation should pay particular attention to Japanese/English communication, contract and payment arrangements, deployment regions, access speed from mainland China, and compliance requirements. The crawled text does not make it possible to determine access conditions from mainland China. Alternatives include working with a China-based Next.js/Jamstack development team, or building an in-house team using a combination of Vercel, Cloudflare Pages, AWS, and a Headless CMS.
