| Verdict | Depends | Depends |
| Best for | Data platform and engineering teams | Enterprise data teams |
| Who it's not for | Small teams with a handful of tables | Small teams wanting a simple data dictionary |
| Privacy | Multiple public CVEs from 2024-2026 (RCE, SSRF, open redirect, SSTI); vendor maintains a public CVE list.⁴ | No known public vulnerabilities found in the sources reviewed. |
| Support quality | No direct support-quality evidence found | No customer support evidence found |
| Public sentiment | r/dataengineering threads show steady interest and constant comparison with DataHub, with self-hosting effort and trust concerns recurring. | Public review snippets praise easy integrations, but the sources contain little detailed, quotable customer feedback. |
| Biggest gotcha | Open-source is not free total cost: you run servers, upgrades, and security patches yourself.⁷ | Pricing is quote-only; expect enterprise sales negotiation and annual commitments. |
