cirosantilli.com is the personal homepage, knowledge base, and project showcase of Ciro Santilli, centered around his open-source knowledge publishing system OurBigBook. The site functions both as the author’s digital garden and as an entry point for open education initiatives, covering university-level STEM, programming, open-source projects, critiques of education systems, blockchain archival research, OSINT projects, and more.
The website is written in OurBigBook Markup and can be published as a static site or synced to the multi-user dynamic instance at OurBigBook.com. The content shows a very large knowledge base, with hundreds of thousands of words and tens of thousands of articles or nodes, organized through a tree-like topic structure. Its focus is not simply “blogging”; rather, it attempts to combine Wikipedia, GitHub, Stack Overflow, and Obsidian-style knowledge management for open STEM textbooks and collaborative knowledge production.
Public content is free to access, the source repositories are open, and the site content is licensed under CC BY-SA 4.0 unless otherwise stated. The author accepts sponsorship via GitHub Sponsors starting from USD 1/month. He also offers private online STEM tutoring and education consulting, but pricing is “to be discussed” and there are no standard packages.
Its strengths are deep content, strong technical depth, high traceability, and a clear commitment to open source and free licensing. The author has a certain reputation on platforms such as Stack Overflow and GitHub, which provides external validation for his ability to explain technical topics. The downsides are that the site is highly personal, information-dense, and not always easy to navigate or read. The content mixes academic, technical, political, and personal viewpoints, so readers need to judge objectivity and applicability for themselves. If you approach it as a mature SaaS product or a standardized course platform, it may feel under-productized.
It is best suited to self-directed STEM learners, technical researchers, people interested in open education, and developers who want to study open-source knowledge publishing tools like OurBigBook. If you need a structured, step-by-step online course with homework grading and certificates, this is not the best choice.
The main domain itself may be directly accessible, but the site relies heavily on external resources such as GitHub, YouTube, Twitter/X, and Stack Overflow, some of which are restricted or require a proxy in mainland China. Overall, access should therefore be considered “partially restricted.”
