What you give up either way
- Real-time multi-user collaboration and presence
- Enterprise admin features (SSO/SCIM, org-level sharing, audit logs)

- Polished templates, UX polish, and extensive customer support
- Advanced add-ons like Cloud Accelerator and bulk cloud imports
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Lucidchart, and it does not prove anyone has run it for a month. How we decide.
