notekpr

A self-hosted, open-source, local-first Markdown knowledge base: Obsidian's plain-Markdown philosophy and offline access, Notion's friendly interface and real-time collaboration — with end-to-end encryption so the server can't read anything.

• Private by design — notes, file names, folders, attachments and history are encrypted on your devices. The server stores ciphertext and coordinates.
• Collaborative — share vaults with family or colleagues as editor or viewer; edit the same note simultaneously with live cursors. Conflict-free merging (CRDTs), also after working offline.
• Plain Markdown — wiki links, backlinks, tags, embeds, export to a folder of .md files at any time.
• Use your own editor — the CLI keeps your vaults as a plain folder of Markdown files, synced live and both ways: edit with Obsidian, Neovim, VS Code or anything else while the server only stores ciphertext (how).
• Easy for everyone — sign in with your existing identity provider (OIDC), one click to set up encryption, a clean editor with a formatting toolbar.
• For AI agents too — give an agent its own identity and keys, share only the vaults it needs; it works with notes through the CLI, a folder of Markdown files, or a local HTTP gateway.
• Rust everywhere — the server, the CLI and the browser client (compiled to WebAssembly) share one core crate for all cryptography and syncing. No npm, no third-party JavaScript.

Features:

• Writing — a live-preview Markdown editor with a toolbar, tables, task lists, code blocks, callouts, colors, images, video and audio; optional Vim keys.
• Drawings — a whiteboard among your notes, drawn together live and shown in any note; compatible with Excalidraw: copy and paste, its files and Obsidian's.
• Organizing and finding — folders with drag and drop, icons, a quick switcher, full-text search, backlinks, a graph, quick notes, a trash and every note's history.
• Working together — share a vault or a single note, edit together with live cursors, comment and @mention.
• Privacy and security — a key for every note, signed membership and edits, new devices approved from one you already use.
• Offline, and your own tools — works offline; the CLI does everything and keeps your vaults as a folder of Markdown files; import (Markdown, Obsidian, Notion) and export.
• For AI agents — their own identity, only the vaults you share, through the CLI, files or an HTTP gateway.
• Running it — one Rust server with SQLite, attachments in S3 or a folder, an admin page, limits and metrics.
