Frequently Asked Questions

How quickly will I get a response?
We aim to respond to all messages within 2–3 business days. Bug reports that affect functionality are typically prioritised and may be addressed sooner.
I found a bug β€” what should I include?
The most helpful bug reports include: (1) the exact diagram text that caused the problem, (2) the output you expected, (3) the output you actually received, and (4) the browser and OS you are using. Opening a GitHub issue is the best way to track bugs publicly.
I have a feature request. Will it be implemented?
We genuinely consider every feature request. The best place to submit one is a GitHub issue, where it can be upvoted by others and tracked publicly. Popular requests with clear use cases are typically prioritised in our roadmap.
Where can I find the documentation?
Full documentation is available in the documentation. It covers the Mermaid ER syntax, PlantUML syntax, all SQL dialects and ORM frameworks, the REST API reference, and how the schema diff tool works. If the docs don't answer your question, feel free to contact us.
