Memos is a self-hosted note-taking server with a chronological, Twitter-like feed for quick thoughts and longer markdown notes. It runs as a single binary backed by SQLite, making it easy to deploy on a personal server or VPS. Privacy here comes entirely from self-hosting: there is no end-to-end encryption, so the security of your notes depends on how you secure your server.

For anyone who wants a fast, zero-friction place to capture thoughts without feeding a cloud service, Memos is hard to beat on simplicity. The Go binary with embedded SQLite means a one-command setup, and the MIT license means you own the stack completely. The catch is worth being clear about: this is not an encrypted notebook. If your server is compromised, your notes are readable in plain text. That makes it a strong pick for self-hosters who already run hardened infrastructure, and a poor fit for anyone who needs confidentiality guarantees without managing their own security perimeter.
