Logseq vs outl

Logseq is a free, open-source platform for knowledge management and collaboration, with tools for notes, tasks, and PDF annotation. It supports Markdown and Org-mode files, and connects information through block references, backlinks, linked references, and queries. Logseq supports note sharing and real-time collaboration, and lists Zotero as an integration. The product says users keep their data locally and can work fully on-device; offline access is listed. It is available on web, Windows, macOS, Linux, iOS, and Android. A plugin and theme ecosystem extends the app, with the homepage listing more than 150 plugins and at least 30 themes. Logseq Sync provides encrypted file syncing across devices. Its public-beta Sync service does not support multiple people using the same graph at once, and the maker warns that data loss can occur. The database version is in beta, while the new mobile app and real-time collaboration features are in alpha; the maker also warns of possible data loss for these. Personal use is free forever. Sync Backer costs $5 a month and Sync Sponsor costs $15 a month, each described as a monthly recurring donation.

outl is a free, local-first outliner and bullet-point note app that stores plain Markdown files on disk. Its nested blocks, wiki-style links, backlinks, tags, and daily journal support structured note-taking. Stable block IDs and metadata are kept in sidecar files rather than the Markdown notes. Notes can be edited offline, and devices on the same Wi-Fi can sync directly without internet; device syncing uses peer-to-peer end-to-end encryption and does not require an account or cloud. Markdown code blocks can run Python, JavaScript, Lua, and Rust, with Lisp available behind a build flag. An MCP server lets compatible hosts including Claude, Cursor, Zed, and ChatGPT read and write local notes. Native desktop builds are listed for macOS, Linux, and Windows, alongside iOS TestFlight and Android APK beta builds. The product is pre-1.0, and the download page describes builds as public beta. The macOS desktop DMG is currently unsigned. An optional Docker deployment can run an always-on peer with a full replica of notes. Export formats include Markdown, JSON, and Hugo; navigation includes search, a fuzzy switcher, and a command palette.
