Every developer blog decision eventually comes down to where the words actually live. Two options dominate: plain Markdown files, or Notion. Both work. Neither is objectively better — they optimize for different things, and picking the wrong one is why a lot of blogs quietly die after a few posts.
This is the trade-off in plain terms, so you can pick once and stop relitigating it. For the bigger picture on tools and platforms, see the developer blogging guide.
What Markdown gets right
Markdown files are just text. That sounds unremarkable until you consider what it unlocks:
You own them completely. No account, no export step, no risk of a service shutting down and taking your archive with it. A .md file works the same in ten years as it does today.
They live in git. Version history, diffs, branches, PRs for edits — the same workflow you already use for code. You can see exactly what changed between drafts, and roll back a bad edit the same way you'd revert a commit.
They move freely between tools. Markdown is the closest thing writing has to a universal format. Static site generators, most blogging platforms, and tools like Blogizi all read it natively — switch platforms later and your content comes with you unchanged.
They fit your existing editor. No new app to learn. Write in VS Code, Vim, or whatever you already have open next to your code, with the same keyboard shortcuts and extensions.
The cost is friction on the input side. Markdown has no visual preview by default, embedding images means managing files or URLs by hand, and there's no built-in commenting or real-time collaboration — you're back to PR review for feedback.
What Notion gets right
Notion is built for writing, not for storage, and it shows in a few places Markdown can't match:
It's fast to start in. Open a page, start typing, format as you go — no file, no folder structure, no frontmatter to remember.
Collaboration is native. Comments, mentions, and real-time co-editing work out of the box. If someone else reviews or contributes to your posts, this alone can be the deciding factor.
Embeds and rich content are easy. Images, embeds, toggles, and databases all drop in without touching a URL or a file path.
The cost is lock-in. Your posts live in Notion's format, in Notion's database, behind Notion's account. Getting content out means exporting — and Notion's Markdown export is not always clean, often mangling nested lists, callouts, or embeds into something you have to hand-fix before it's usable elsewhere. There's no real diff or version history in the git sense, and no offline file you can grep, back up independently, or hand to another tool without going through that export step.
The actual decision
The honest way to choose is by asking what you're optimizing for:
Pick Markdown if you want long-term ownership, you're comfortable in a text editor, you want your posts versioned alongside your code, or you might switch blogging platforms later and don't want to redo the migration.
Pick Notion if you're writing collaboratively with non-developers, you want zero setup before your first post, or the writing itself is the bottleneck and file management would just slow you down.
A middle path a lot of developers land on: draft loosely in Notion when a teammate needs to weigh in, then convert to Markdown before publishing. It costs one export step per post but keeps the archive portable.
Where this fits into your publishing workflow
If you're writing in Markdown, the next question is what turns that file into a published, SEO-formatted post without extra manual steps — covered in best developer blogging platforms. Tools like Blogizi are built specifically around this: write the .md file locally, run one publish command, and skip the CMS entirely. See blogging from your terminal for what that looks like end to end.
If you're staying in Notion, budget for the export-and-clean-up step as a permanent part of your workflow rather than a one-time cost — it recurs with every post.
