What to include
Please include the tool URL, the diagram format, a short description of the issue, and whether the problem affects preview, export, localization, metadata, or generated content.
If the issue is about rendering, include a minimal input sample that reproduces the problem. If the issue is about account, billing, or a third-party provider, do not include API keys or secrets.
Response scope
DiagramPreview is a self-serve web toolbox, so most support is handled by email and product updates. Reports that include a reproducible sample are much easier to verify and prioritize.
