Hi all,
I built a simple tool for educational purposes. It lets you analyze potential weak spots in your workflow— like missing retries, no error workflow, or unhandled failures and provides suggestions for improvement. You can use it to check your workflow for resilience and learn more about related concepts.
The tool is available here: https://flowcheck-learning-edition.lovable.app/
This is how it works: Paste your exported n8n workflow JSON, and Flow Check will analyze it.
It’s still a work in progress, but already covers the basics of error handling and recovery.
If you’re exploring n8n or just learning automation, I’d love your feedback, ideas, or bug reports!
I’m thinking about making it Open Source, in case there is any interest in the tool.
Hey @annafischer, this looks really useful — I tried Flow Check with one of my older automation workflows and it immediately pointed out a couple of retry gaps I hadn’t noticed. The idea of turning this into an open-source educational tool sounds great, especially for people learning n8n or general automation design.
One small suggestion — maybe include a few “before and after” examples for common issues like unhandled errors or timeout handling. Visual comparisons can really help beginners understand how resilience improves with small tweaks.
Also, for anyone collecting study material or reference slides about workflow design and automation concepts, I’ve often relied on a resource like this one to quickly grab relevant slides for review. It’s handy when you’re documenting learning progress.
Overall, fantastic initiative — this could turn into a really valuable teaching aid if expanded further!

Hey @annafischer , this is super helpful for beginner and amateur n8n users!
I am interested in the source code of the tool!

Thank you! I am currently not working on the tool, but I just published it Open Source and might continue if there is enough interest
