AppFlowy vs Obsidian

AppFlowy is an open-source collaborative workspace that covers notes, wikis, databases and project boards, positioned as a privacy-focused alternative to Notion. It is built with Flutter for the interface and Rust for the core, so it ships as native apps for macOS, Windows, Linux, iOS and Android rather than a web wrapper, and its source code is published on GitHub under the AGPL license.

The core product combines rich documents with databases that can be viewed as a grid, kanban board or calendar, plus templates, offline mode and an AI assistant for writing, summarising and asking questions about your content. You can use AppFlowy Cloud as a hosted service with a free tier and paid per-user plans, or self-host the backend with Docker so that every page and database stays on your own servers.

AppFlowy fits developers, privacy-conscious teams and organisations with data residency rules who want a Notion-style experience without handing their content to a third party. It is less mature than Notion in integrations, templates, permissions and the polish of real-time collaboration, and its plugin ecosystem is small. Anytype is the other well-known open-source, local-first option; AFFiNE combines docs with whiteboards; Notion remains the safer choice when a broad integration ecosystem matters more than data ownership.

Obsidian is a local-first knowledge base and note-taking app made by Dynalist Inc., launched in 2020 by Shida Li and Erica Xu. Notes are plain Markdown files in a folder on your own device, linked with wikilinks and shown as a graph, so your notes stay readable by any text editor and nothing reaches Obsidian's servers unless you choose its paid services.

The core app includes backlinks, a graph view, Canvas for visual boards, daily notes, templates, powerful search, Bases for database-style views over notes, and apps for Windows, macOS, Linux, iOS and Android. A community ecosystem of more than 2,000 plugins and many themes adds task management, calendars, spaced repetition, Dataview queries, Zotero integration, Kanban boards and much more. Obsidian is free for personal use and, since 2025, for commercial use as well; paid add-ons are Sync for end-to-end encrypted syncing with version history and Publish for turning notes into a website, plus an optional one-time Catalyst supporter license.

Obsidian suits individuals, researchers, students, developers and writers who want long-term ownership of their notes and deep customization. It is single-player by design, with no real-time collaboration, and the plugin ecosystem can tempt users into endless setup. Notion and Outline are better for shared team wikis, Logseq offers a free outliner-based alternative with similar local files, and Apple Notes or Bear suit people who want zero setup.

The introduction of Bases in 2025 brought database views into the core app, reducing reliance on community plugins for structured notes.
