|---|---|---|
| Verdict | Depends | Worth it |
| Best for | Self-hosters and homelab users | Small businesses and solo founders |
| Who it's not for | Teams with no Linux/Docker admin capacity | Orgs already standardized on Microsoft 365 |
| Privacy | Pattern of CVEs 2024-2026 including RCE, SSTI, XSS, and auth bypass; fine if patched fast, risky if neglected. | Platform security is strong; public findings center on misconfiguration, phishing/OAuth abuse, and third-party tools . not core Workspace CVEs. |
| Support quality | Community forum and docs only; quality unverified | Trustpilot 1.3/5; 'ghost company' complaints |
| Public sentiment | Users praise its completeness but warn it is resource-hungry and overkill for simple needs.² | Users rate the tools highly but consistently knock the support experience.13 |
| Biggest gotcha | "Free" isn't free: expect $170-400/yr VPS plus hours of admin time⁴ | Existing customers reported 29% price increases . budget for hikes at renewal. |
