About TagSpaces

TagSpaces is a free, open-source app for sorting, labeling and handling the files stored on your own computer. It works completely offline, with no cloud service, internet connection or vendor lock-in, and it keeps your documents as ordinary files and folders on your own disk.

It runs on Windows, Linux and macOS and includes a Web Clipper browser extension for Firefox, Edge and Chrome that captures online content as local files. Repository topics include note taking, offline-first and self-hosting, and the app offers file and folder management plus tagging so information can be found without a proprietary database.
