Editorial illustration: Obsidian Alternatives 2026: 5 Free Options

Verdict:Obsidian's core app is free with no limits, including commercial use, and your notes stay on disk as plain files. Leave it for a reason the free tier does not fix. Usually that means you want open source, you need a shared space for a small team, or you need sync without paying $4 a month billed annually. Logseq is the outliner choice: free, AGPL-3.0, and built around nested bullets rather than long documents. Joplin is free and open source too, and it can sync through Dropbox or OneDrive, so Joplin Cloud is optional. AFFiNE is MIT-licensed, and its Cloud Basic plan covers up to three members with 10 GB. AppFlowy has an open-source core, but its free personal plan caps storage at 100 MB, so it works for small workspaces better than for a large archive. Notion is the one to avoid if you want local files, because it is closed source and runs in the cloud. Stay with Obsidian if you write alone and your notes fit in one vault.

Good fit if

  • You want an open-source notes app built around an outliner (Logseq is the pick)
  • You want sync through a drive you already pay for (Joplin is the pick)
  • A small team needs shared pages on a free tier (AFFiNE is the pick)
  • You need team databases and an online editor (Notion is the pick)

Not ideal if

  • You rely on Obsidian features or integrations that these tools do not replicate

Obsidian today: Free (core app with no limits, including commercial use); paid from $4 per user/month, billed annually (Sync add-on; $5 billed monthly) (Obsidian pricing, checked 2026-10-22).

Why people look for Obsidian alternatives

The Obsidian app is described as free without limits, but sync and publishing are separate paid add-ons: Sync is $4 per user per month billed annually ($5 monthly) and Publish is $8 per site per month annually ($10 monthly). A commercial license is listed at $50 per user per year. Using notes across devices therefore means either paying for Sync or setting up your own syncing.

FAQ

Is there a free open source Obsidian alternative with sync?

Joplin is AGPL-3.0-or-later open source and syncs through Joplin Cloud, Dropbox, OneDrive and other services with end-to-end encryption, so you can avoid a sync subscription if you already use a cloud drive. Obsidian's own Sync add-on costs $4 per user per month billed annually.

What is a good self-hosted Obsidian alternative?

AppFlowy and AFFiNE both list a self-hosted option. AppFlowy is AGPL-3.0, while AFFiNE is MIT-licensed and also offers local workspaces. Check the AppFlowy free plan first, which lists 100 MB of storage, 7 MB uploads and 7-day version history.

Which Obsidian alternative works on Android?

Joplin, AppFlowy and Notion list Android apps. Logseq's mobile app for the database version is on iOS for now, with Android marked as coming soon. AFFiNE lists web, Windows, macOS, Linux and self-hosted options but no Android app.
