| Compare | Just the Docs | GitBook |
|---|---|---|
| Verdict | Worth it | Depends |

| Who it's not for | Non-technical teams . no Ruby/Jekyll skills, no site | Solo writers wanting a cheap wiki |
| Privacy | No known public vulnerabilities found in the sources reviewed.13 | Hosted product maintains a trust center and disclosure program; known CVEs affect only the legacy open-source CLI, not the current SaaS. |
| Support quality | Community-funded project; GitHub issues, no SLA | No direct support evidence found |
| Public sentiment | Users value the clean docs output and search, but setup, customization, and GitHub Pages builds are recurring friction points.⁹ | Users praise GitBook's clean editor and organization, but pricing changes are the dominant complaint.16 |
| Biggest gotcha | Jekyll dependency and version mismatches cause frequent GitHub Pages build errors11 | ~$65 per site reported; every extra doc site multiplies cost |
