Obsidian vs Logseq

Obsidian is a free, local-first Markdown knowledge base with a plugin ecosystem thousands strong; Logseq is a free, open-source, local-first outliner with flashcards and a privacy-first ethos. Here’s how they compare on pricing, platforms, linking, search, capture and collaboration — and how to decide between them.

What is Obsidian?

Obsidian stores your notes as plain Markdown files in a folder on your own device — a “vault” you can read with any text editor, back up however you like, and keep forever. On top of those files it layers backlinks, a graph view, a Canvas whiteboard, and Bases (native database views over your notes, added in 2025). The app is completely free, including for commercial use since early 2025.

Its defining feature is the community: roughly two thousand plugins extend it with everything from spaced repetition to Kanban boards to AI integrations. Official add-ons are paid — Sync ($4/month, end-to-end encrypted) keeps vaults identical across devices, and Publish ($8/month) turns notes into a public site. There’s no web app; Obsidian runs as desktop and mobile apps against your local files.

What is Logseq?

Logseq is the open-source counterpart to Roam: an outliner built on bidirectional links and daily notes, but storing everything as local Markdown (or Org-mode) files on your device. It’s free, AGPL-licensed, and adds flashcards with spaced repetition, PDF annotation, queries, whiteboards and a plugin ecosystem. Sync is available end-to-end encrypted, or you can roll your own with Git or Syncthing.

The project is mid-transition: alongside the classic Markdown version, a rebuilt “DB version” backed by a local database entered public beta in July 2026, bringing real properties and Tana-style structured tags plus more reliable sync. That rewrite consumed several years of development attention, so the classic version evolved slowly — but the foundation of free, local, open-source outlining has kept a devoted community.

Where Obsidian shines

• True data ownership: plain Markdown files on your disk, readable by any app, with no account required and no lock-in.
• The largest plugin ecosystem in the category — if you want a workflow, someone has probably built it.
• Free for personal and commercial use; you only pay for optional Sync or Publish.
• Bases and Canvas add database views and visual thinking without leaving your local vault.
• End-to-end encrypted sync (as a paid add-on) for the privacy-conscious.

Worth knowing: There’s no web app, and multi-device use effectively requires paid Sync or DIY setups. Collaboration is weak — shared vaults exist but there’s no real-time co-editing. Out of the box it’s fairly bare; the power comes from configuring plugins yourself, which is a hobby in its own right. Capturing web content, newsletters or feeds means assembling extensions and plugins rather than anything built in.

Where Logseq shines

• Free and open source (AGPL) with local-first storage — the strongest ownership story among outliners.
• Built-in spaced-repetition flashcards and PDF annotation, no plugins needed.
• Block references, queries and whiteboards cover most of Roam’s power features.
• The new DB version adds structured properties and tags with trustworthy sync.

Worth knowing: No real-time collaboration — it’s a single-player tool. The MD-to-DB transition splits the product; some features (like whiteboards) are temporarily missing from the DB beta. Polish and mobile experience trail the paid competition, and web capture relies on community tooling.

Which should you choose?

Choose Obsidian if:

• You want your notes as local files you fully control, independent of any company’s servers.
• You enjoy tinkering and want to assemble a personalized system from plugins.
• You work offline often or in environments where cloud tools are off-limits.
• You want a free tool with no note limits.

Choose Logseq if:

• You want Roam-style outlining without the subscription, as open-source software.
• Local files and end-to-end-encrypted sync are non-negotiable.
• You want flashcards built into the same tool as your notes.

A third option: Dexi

If what you actually want is one searchable place for notes, bookmarks, newsletters and RSS — with tags, @mentions and [[wiki links]] that organize themselves as you write, semantic search that finds ideas even when the words don’t match, and an MCP server so Claude and other AI assistants can work with your notes directly — take a look at Dexi. It’s free for up to 1,000 notes, with no app to install.
