GitLab Pages is GitLab's answer to GitHub Pages — free static hosting driven by your CI/CD pipeline rather than a simple git push. If your team already lives in GitLab, it's a reasonable default. The trade-offs are largely the same ones that come with any static hosting option: the hosting is free, everything else about running a blog is still on you.
For the wider field of options, see best developer blogging platforms, and GitHub Pages vs Blogizi for the closely related comparison on the GitHub side.
What GitLab Pages gets right
Free HTTPS hosting, custom domain support, and deep integration with GitLab CI/CD — your .gitlab-ci.yml builds whatever static site generator you're using (Hugo, Jekyll, Eleventy, plain HTML) and deploys the output automatically on push. If your team already has GitLab CI expertise, this is genuinely low-friction to set up.
Where it costs you
The generator you choose determines everything else — sitemap, RSS, and OG image support all depend on whatever plugins or manual setup that generator requires, the same trade-offs covered in the sitemap guide, RSS feed guide, and how to add OG images. GitLab Pages itself doesn't add any of this — it's purely the hosting and build-pipeline layer.
Publishing a post means a commit, a CI pipeline run, and a wait for the build to finish and deploy — slower feedback than a direct publish command, and one more thing that can fail (a broken build, a CI runner issue) between writing and going live.
Where Blogizi differs
Blogizi skips the pipeline entirely: blogizi publish path/to/post.md reads the file's frontmatter and the post is live, with no CI job to wait on and no build to break. Sitemap, canonical URLs, and per-post OG images are generated automatically per project — see the technical SEO checklist.
The actual decision
Pick GitLab Pages if: your team already runs on GitLab CI/CD and free static hosting integrated into your existing pipeline is worth more to you than a faster, simpler publish step.
Pick Blogizi if: you'd rather not wait on a CI pipeline for every post, and want sitemap, RSS, and OG image support without picking and configuring a static site generator first.
