Real, tested workflows — not rewritten changelogs
Hi, I’m Jeonghoon. I’m a solo developer and operator based in South Korea, and WorkflowDen is where I document what actually works (and what breaks) in AI coding and automation tools — Claude Code, n8n, Cursor, and whatever ships next.
English is my second language. What I can’t polish in prose, I make up for in screenshots and working code.
Why this site exists
The official docs tell you what a feature should do. They rarely tell you what happens when it doesn’t — the version-specific bugs, the usage limits you hit mid-task, the settings that silently changed after an update. That gap is what WorkflowDen covers.
How I work
- Everything is tested on my own machine before publishing. The screenshots are from my actual sessions, with version numbers visible.
- I pay for my own subscriptions. I’m not affiliated with or endorsed by Anthropic, n8n GmbH, Anysphere (Cursor), or any tool I write about.
- Posts get updated. AI tools change weekly, so every post shows a “Last updated” date, and I refresh the most-read guides monthly.
- Found a mistake? Email me at hello@workflowden.com — I fix posts within 48 hours.
What I cover
- Claude Code — usage limits, model settings, troubleshooting, plan comparisons
- n8n — automation workflows, error handling patterns, and self-hosting guides
- Cursor — setup, pricing, and comparisons (coming soon)

About the author
WorkflowDen is written and run by one person: Jeonghoon, a Korean developer and builder. The site covers self-hosted n8n automation and Claude Code workflows — specifically, what happens when you actually run them, not what the documentation says should happen.
Every post here follows the same method: run it, break it, screenshot it, then write. Nothing gets published from release notes or secondhand summaries. The screenshots are from Jeonghoon’s own machines, the version numbers are the ones actually installed, and the measurements come from his own logs — including the nightly /usage logs he keeps on his Claude subscription. When tools change (in this space, that’s weekly), posts get dated updates rather than quiet rewrites.
Some of that testing has turned into things readers use directly: a seven-workflow error-handling set exported as downloadable JSON files, and an n8n release watcher that monitors npm for new versions. That watcher is the same workflow that messaged him overnight in July 2026 when Anthropic rolled back a Claude Code release — the alert became a post the next morning.
Current test setup: Windows 11 PC · self-hosted n8n 2.29.9 in Docker · Claude Max subscription (paid for out of his own pocket).
A note on how these posts are made: Jeonghoon thinks and drafts in Korean, then uses AI tools to polish the English wording. The testing, the numbers, and the screenshots are entirely his own work, and he verifies every technical claim against his own logs before it goes live. Human-tested and human-verified first; polished second.
