Docusaurus is, first and foremost, a documentation-site framework — versioned docs, sidebar navigation, search, and MDX support are the core of what it's built for. It ships with a blog feature, but it's worth being clear-eyed about what that feature actually is: a secondary capability on a tool designed around something else.
For the wider field of options, see best developer blogging platforms.
What Docusaurus gets right
If you're already building versioned product documentation — the kind with a "docs for v2, docs for v3" structure — Docusaurus is a strong, well-maintained choice, and having a blog live in the same site, sharing the same theme and navigation, is genuinely convenient. MDX support means you can drop React components directly into posts when you need something more interactive than plain Markdown.
Where it costs you
The blog plugin (@docusaurus/plugin-content-blog) covers the basics — post listing, tags, pagination, RSS — but it's noticeably thinner than a dedicated blogging tool: no built-in OG image generation, no per-post analytics, and design customization means working within Docusaurus's theming system rather than a blog-specific one. If your actual goal is a strong standalone blog rather than docs-plus-blog, you're carrying the weight of a full documentation framework to get a secondary feature.
There's also a build step and a deploy pipeline to maintain, same as any React-based static site generator.
Where Blogizi differs
Blogizi is built around one thing: the blog itself. Posts are Markdown files with frontmatter, published with blogizi publish path/to/post.md — no docs framework to run alongside it, no build step. OG images, sitemaps, and canonical URLs are generated automatically per post rather than left to a secondary plugin — see the technical SEO checklist.
The actual decision
Pick Docusaurus if: you need real versioned documentation and want a lightweight blog living in the same site — the docs are the primary need, and the blog is a bonus.
Pick Blogizi if: the blog is the actual goal, not a secondary feature on top of a documentation framework you'd otherwise not need.
