korosuke613.dev is the personal technical homepage of Futa Hirakoba (korosuke613). The crawled content indicates that the author is a software engineer at Cybozu, with a focus on topics such as developer productivity, CI/CD, IaC, and public cloud. The site mainly aggregates the author’s Posts, Blogs, Slides, and the long-running Productivity Weekly series.
The site functions more like a personal technical content portal. The top navigation provides categories for Posts, Blogs, and Slides; the homepage showcases featured content and recent articles; article pages include tags, publication dates, related article recommendations, Tweet sharing, a GitHub edit link, and edit history. Recently, a Slides list feature has also been added, aggregating presentation materials from platforms such as SlideShare, SpeakerDeck, and Docswell, while also supporting random content pages and a full-text search index.
No commercial pricing, subscriptions, memberships, or paid content information was found. The site should currently be regarded as a free, publicly accessible personal blog/resource archive rather than a customer-facing product for sale.
The strengths are its clear content focus, with a technical stack and topics oriented toward engineering practice. It is useful for readers interested in GitHub, CI/CD, automation, Astro site building, and developer productivity. The site is built with Astro, has a lightweight structure and clear navigation, and makes its source code and GitHub edit links public, offering a good level of transparency.
The drawbacks are that it is not a platform-style service and lacks features such as accounts, community interaction, APIs, and commercial support. The content is mainly in Japanese, which makes it less friendly for Chinese-speaking users. The breadth of materials and ongoing updates also depend entirely on the individual author. In addition, some slide or blog links rely on external platforms, so the browsing experience may be affected by third-party services.
It is suitable for software engineers, DevOps/cloud-native practitioners, technical bloggers, and anyone looking for inspiration for the information architecture of a personal technical homepage. If you are looking for structured courses, commercial tools, or a Chinese-language technical community, it is not the most suitable choice.
Judging by the domain and content format, this appears to be an ordinary personal static website with no obvious characteristics of restricted services, so it is expected to be directly accessible from mainland China. However, external links such as GitHub, Zenn, and Docswell may vary in speed or availability depending on the network environment.
