What plumio is

Plumio is a free, self-hosted note-taking app for individuals and teams that want to keep data on infrastructure they control. It runs on the web, supports offline access, and also provides an API. Notes use the Milkdown editor, with GitHub Flavored Markdown, highlighted code blocks, Mermaid diagrams, mathematical equations, tables, and task lists. You can create multiple organizations, arrange notes in folders, add tags, and search or filter documents. Import options include Standard Notes JSON exports, Obsidian markdown folders, and other markdown files; notes can be exported as a ZIP. Deployment works through Docker, Docker Compose, or from source. The FAQ describes local storage without external-service transmission, telemetry, or tracking. Optional AES-256 encryption at rest, JWT authentication, bcrypt password hashing, and HTTPS through a reverse proxy are available. The free plan costs nothing and has no premium tiers or paid features.
