Squarespace is built for a different kind of user than the rest of this list — polished, design-forward, all-in-one sites for creatives and small businesses where the blog is one content type among portfolios, stores, and booking pages. It's a genuinely good product for that audience. Developers writing technical content aren't really who it's built for.

What Squarespace gets right
Beautiful, professionally designed templates with a drag-and-drop editor that requires no code at all. Hosting, commerce, scheduling, and email marketing are bundled in, so a small business or creative professional can run their entire online presence from one dashboard without touching a line of code.
Where it costs you
There's no file-based, git-versioned content — posts live entirely inside Squarespace's editor and database, with no local Markdown files to write in your own editor or track changes on. Code blocks and technical formatting are supported but clearly secondary to the platform's design-first templates; syntax highlighting and inline code rendering feel bolted on rather than native. SEO tooling is solid for general use but generic — you're working within Squarespace's built-in fields rather than controlling canonical tags, structured data, or sitemap behavior at the code level.
Where Blogizi differs
Blogizi is built around exactly the workflow Squarespace doesn't support: Markdown files with frontmatter, written in your own editor, versioned in git if you want, published with blogizi publish path/to/post.md — see blogging from your terminal. Sitemaps, canonical URLs, and per-post OG images are handled automatically, and code blocks render the way a technical reader expects — see the technical SEO checklist.
The actual decision
Pick Squarespace if: you need a polished all-in-one site — commerce, bookings, portfolio, blog — and don't need code-level control over your content or its SEO plumbing.
Pick Blogizi if: the blog is a technical, code-heavy publication first, and you want to write in your own editor rather than a drag-and-drop CMS.
