Diagram proxy
- Tier: Free, Premium, Ultimate
- Offering: GitLab Self-Managed, GitLab Dedicated
Use the diagram proxy to prevent browsers from sending diagram content to external services like Kroki or PlantUML. GitLab fetches diagrams on the user’s behalf and serves them through a one-time URL that expires after use.

Turn on the diagram proxy separately for the Kroki and PlantUML integrations. You can turn on the diagram proxy for Kroki, PlantUML, or both.

- In the upper-right corner, select Admin.
