| Compare | Leantime | OpenProject.org |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Small self-hosting teams | Public institutions and enterprises needing on-prem |
| Who it's not for | Enterprises needing compliance-grade security | Small teams wanting a simple to-do list . this is a heavy suite |
| Privacy | Multiple CVEs in 2025-2026, including authentication bypass, broken access control, and XSS . patch fast if self-hosting.⁸ | Transparent CVE disclosure with external audits, but a real history: SQL injection, XSS, data exposure, and a Docker default-secret RCE . patch promptly. |
| Support quality | No demo; opaque plugin pricing | Trustpilot 4/5 but tiny 11-review sample |
| Public sentiment | G2 raters like the idea-to-action flow, while some r/selfhosted users found it buggy and the site unhelpful.³ | Reviews skew positive on Capterra and GetApp, but G2 sits near 3.8/5 and some users find it heavier than they need.16 |
| Biggest gotcha | Self-hosted updates are not automatic; outdated installs stay exposed to known CVEs.10 | Self-hosting means you own patching; known CVEs make lagging updates genuinely risky |
