Our verdict on ZeroNote
ZeroNote is an open-source note-taking app and personal data vault for individuals managing notes, documentation, bookmarks, credentials, and personal knowledge bases. It stores notes locally in IndexedDB with client-side AES encryption, supports offline access, and provides Markdown rendering with split-screen editing. Smart tags can organize note types and structured fields, while search covers notes, titles, and content. Attachments support images, PDFs, and documents. Its strongest fit is for people who want a private, self-managed workspace rather than a shared team notebook.
The product’s main distinction is the combination of local-first storage, encryption, and optional synchronization. WebRTC peer-to-peer synchronization can connect devices directly, while encrypted backup synchronization supports AWS S3 and MinIO. That gives users a choice between device-to-device syncing and S3-compatible backup storage. The broader personal-vault scope also includes password management, bookmark management, and TOTP codes. These capabilities make ZeroNote more than a basic text notebook, but the published platform coverage is limited to the web.
ZeroNote’s most important limitation is its maintenance status. It is no longer maintained, development and support have stopped, and the repository was archived on July 16, 2026. That makes it a poor choice for users who need ongoing fixes, active support, or a current collaboration ecosystem. It is better suited to technically confident individuals who accept that trade-off and value open-source software, offline storage, client-side encryption, and control over backups. Users seeking verified sharing, collaboration, broader platform access, or an actively maintained product should choose an alternative.
