| Compare | Memos | Obsidian |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Self-hosters comfortable with Docker | Personal knowledge bases |
| Who it's not for | Teams wanting vendor support, SLAs, or compliance guarantees | Teams needing shared, out-of-box collaboration |
| Privacy | Self-hosted, so data stays with you . but the project is pre-1.0 with three public CVEs since 2025.⁵ | Private, local-first design with third-party audits, but the plugin ecosystem has attracted real malware abuse.12 |
| Support quality | Guess: community support only, no vendor SLA | No direct support-quality evidence found. |
| Public sentiment | Self-hosters on Reddit and reviewers describe Memos as a fast, simple daily-notes tool that is intentionally minimal.10 | Users love the flexibility and adaptability but frequently flag the steep learning curve, and some long-time fans are drifting away. |
| Biggest gotcha | Patch fast: XSS (CVE-2026-30586) and other 2025-2026 CVEs are public⁷ | Malicious plugins have been abused to deploy malware; vet third-party plugins carefully.12 |
