Feisky.xyz is Feisky’s personal technical blog and portfolio hub. Based on the site content, the author is a Geek Time columnist with a long-standing focus on Kubernetes, Linux performance optimization, eBPF, SDN, AI Infra, AI Agents, and related areas. This is not a traditional news outlet or SaaS product; it is better understood as a Chinese-language technical news and in-depth analysis blog for engineers, and is therefore best categorized as a personal tech blog under “news and information.”
The site mainly offers three types of content. First, it publishes regularly updated technical articles, with many recent posts covering Claude Code, Codex CLI, AI coding assistants, Agentic AI, AI Infra, and large-model infrastructure. Second, it provides entry points to the author’s open-source projects, including claude-code-settings, codex-settings, koder, mcp-kubernetes-server, and kube-copilot. Third, it serves as an index of resources, such as the open-source books Kubernetes Guide and SDN Guide, Geek Time columns, and records of technical talks from events such as KubeCon.
The articles and resource links on the site appear to be free to access, and no membership subscription or paywall was found. Note that the Geek Time columns recommended on the site are external commercial courses; whether they are paid and how much they cost should be checked on the Geek Time platform. The site itself does not provide a clear pricing plan.
The main advantages are its high level of technical depth and highly focused subject matter, making it especially suitable for readers interested in the intersection of cloud native technologies and AI engineering. Many articles are tied to real-world tools and open-source projects, which makes them practical, and the Chinese-language writing lowers the barrier for domestic engineers to understand cutting-edge English-language materials. The downside is that it remains a personal blog, so its information architecture and learning paths are not as complete as those of a structured course platform. The content also skews advanced, and readers without a foundation in Kubernetes, LLM toolchains, or DevOps may find it hard to follow. In addition, the site does not provide formal technical support or service guarantees.
Feisky.xyz is suitable for Kubernetes platform engineers, SREs, DevOps engineers, backend developers, AI Infra engineers, and technical users exploring AI Agents, AI coding assistants, and the MCP ecosystem. It is less suitable for users looking for beginner-friendly courses from scratch, commercial product procurement, or non-technical popular science content.
The author is listed as being based in Shanghai, and the site is in Chinese. Based on the crawled information, it does not appear to rely on any obviously restricted login process, so it is likely directly accessible from mainland China. However, some external links referenced in articles, such as GitHub, X, or overseas model service links, may have access restrictions.
