Automate Your Dev.to Publishing With This Simple Python Script

Every developer who writes on Dev.to knows the pain: you finish writing a great article, save it as markdown, then spend 5 minutes clicking through the publishing UI. Do that for a 5-article series and you've wasted 25 minutes.

I built a command-line tool that reduces this to one command.

How It Works

The script reads all markdown files from a directory, extracts metadata from YAML frontmatter, logs into Dev.to via your credentials, and publishes each article in sequence.

Before:

✗ Open browser
✗ Navigate to dev.to/new
✗ Paste content
✗ Add tags
✗ Click publish
✗ Repeat 5 times
→ ~25 minutes

After:

$ python publish.py ./articles/
→ ~30 seconds

The Tech

The script handles three tricky parts of Dev.to's backend:

CSRF Token Chain — It extracts the authenticity token from the login page, authenticates, then gets a fresh token from the dashboard that works for article creation.
Session Persistence — Saves session cookies to a JSON file so you don't need to re-login every time. Sessions last for weeks.
Rate Limit Handling — Dev.to allows roughly one publish per 30 seconds. The script auto-waits between publishes and retries on failure.

Real-World Test

I've published 5 articles using this tool across different topics — all went live without issues. The script handled everything from login to final publish.
