| Compare | ||
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Privacy-focused solo note-takers | Personal knowledge bases |
| Who it's not for | Teams handling sensitive data . RCE CVE, ignored XSS reports | Teams needing shared, out-of-box collaboration |
| Privacy | Active 2026 CVEs include remote code execution; researchers report ignored XSS findings; no dedicated security page found.⁸ | Private, local-first design with third-party audits, but the plugin ecosystem has attracted real malware abuse. |
| Support quality | Security reports allegedly ignored for months | No direct support-quality evidence found. |
| Public sentiment | Sentiment is split: privacy-minded fans praise the lightweight local-first design, while others complain it feels raw and unstable.⁴ | Users love the flexibility and adaptability but frequently flag the steep learning curve, and some long-time fans are drifting away.13 |
| Biggest gotcha | Open-source license is not MIT despite marketing framing; verify terms before commercial use⁷ | Malicious plugins have been abused to deploy malware; vet third-party plugins carefully. |
