Productivity & Notes covers open-source tools for capturing information, organizing tasks, and managing personal or team knowledge. This includes note-taking apps built around local-first storage and markdown files, such as Logseq, AppFlowy, and Joplin, encrypted note apps like Standard Notes, and task and project management tools such as Focalboard and Wekan. Many projects in this category emphasize data ownership: notes are stored as plain files or in a local database rather than locked inside a proprietary format on someone else's server.
The main split is between outline-and-link tools built for networked thought (Logseq, backlink-heavy wikis) and traditional folder-and-note apps closer to a notebook (Joplin, Notesnook). Teams managing tasks instead of notes look at kanban-style boards (Wekan, Focalboard) or full project trackers, which usually add features like due dates, assignees, and status columns on top of basic note storage.
Sync and storage model are practical deciding factors. Some tools store everything locally and sync through a file service you control (Syncthing, a private server, or plain git), while others ship with their own hosted sync backend that can also be self-hosted for teams that want control over where data lives. End-to-end encryption is worth checking directly in the project docs if notes will contain sensitive information, since not every tool encrypts data at rest by default.
