Jotty

Jotty is more focused than Notion: a self-hosted app for personal notes and checklists rather than a full wiki/database platform. It is licensed under AGPL-3.0, built with Next.js and the TipTap editor (with syntax highlighting and full Markdown support), and is geared toward individuals or small teams managing tasks and notes rather than building block-based documents.

Jotty is fully file-based — there is no database. Notes are stored as Markdown and checklists as JSON inside a single data/ directory that you mount as a Docker volume. That means backups are as simple as rsync or tar on the host, and you can read, edit, or version your content with normal Unix tools.

Yes — Jotty offers full PGP encryption for notes, documented in howto/ENCRYPTION.md in the repo. Encryption and decryption are done per-item, and the project explicitly markets this as a privacy-first feature for self-hosters. The app is also themable, with 14 built-in themes plus custom theme and emoji support.

There is no native mobile app, but Jotty is built mobile-first as a PWA — install it to your home screen and it behaves like an app-store app. The README is upfront about offline behavior: pages you've visited while online are cached and re-readable offline, but offline CRUD (create/edit) is not yet supported.
