Zen Notes, a fast, self hosted markdown notes app that keeps your knowledge base entirely under your control.
Zen Notes is an open source, single binary note taking application that stores every note as markdown inside a local SQLite database with full text search, flexible tags, templates and image uploads. It gives individuals a private, low resource place to capture and organise ideas without a hosted service.
cloudimg ships Zen Notes preconfigured on a hardened, fully patched Ubuntu 24.04 base behind nginx TLS so the web interface is ready right after boot. A unique administrator credential is generated on first boot with no default login, notes live on a dedicated data volume, and 24/7 support is included.
