People leave Obsidian for a handful of reasons, and they’re not the same reason. Some want something lighter, because a plugin-heavy vault takes several seconds to open and eats memory in the background. Some want something simpler, because they set up a knowledge management system and then never used the graph view once. Some want something with real sync that doesn’t cost extra. And some just don’t want an Electron app.
Which alternative is right for you depends entirely on which of those you are. So before the list, one question worth answering honestly.
First: do you need a knowledge base, or an editor?
Obsidian is two things bolted together. It’s a markdown editor, and it’s a knowledge management system on top of that editor: backlinks, the graph view, tags, daily notes, plugins, and a “vault” concept that treats a folder as a database.
A lot of people install Obsidian for the second thing, use only the first thing, and then feel like the app is too heavy. If that’s you, you don’t want an Obsidian alternative at all. You want a markdown editor, and the rest of this list will look overbuilt.
If you genuinely use backlinks and the graph, you want a like-for-like replacement, and the first few options below are the real candidates.
Either way, the good news: Obsidian stores your notes as plain .md files in an ordinary folder. There’s nothing to export and nothing to convert. Every app below that reads markdown can point straight at your existing vault folder.
Like-for-like replacements
Logseq
Logseq is the closest philosophical match to Obsidian. It’s open source, stores notes as local markdown (or org-mode) files, and supports backlinks, daily notes, and a graph view.
The main difference is structure: Logseq is an outliner. Everything is a bullet point, and blocks are the unit you link and reference, rather than whole pages. People who think in nested lists tend to prefer it immediately; people who write in paragraphs often find it fights them.
Pros: Open source, local-first, block-level linking, strong daily-notes workflow. Cons: The outliner model isn’t optional. Also Electron, so it isn’t meaningfully lighter than Obsidian. Best for: Obsidian users who want the same capabilities with a block-based structure.
Joplin
Joplin is an open-source notes app with markdown at its core, and it’s the usual recommendation when sync is the sticking point. It supports end-to-end encrypted sync across a range of backends, including ones you host yourself.
Notes live in a local database rather than as loose .md files, which is a real trade-off: you get better sync and search, but you lose the “it’s just a folder” property that makes Obsidian vaults so portable. Import and export are both supported.
Pros: Free and open source, flexible encrypted sync, mobile apps, web clipper. Cons: Notes aren’t plain files on disk. Interface is functional rather than polished. Best for: People whose main complaint about Obsidian is sync.
Zettlr
Zettlr is a markdown editor aimed at academic and long-form writing. It works directly on a folder of markdown files, and supports internal linking, citations via BibTeX/Zotero, and export through Pandoc.
It’s less of a “second brain” tool and more of a serious writing environment that happens to understand linked notes.
Pros: Open source, excellent citation and export handling, works on plain folders. Cons: Narrower focus. If you don’t write papers or long documents, much of it goes unused. Best for: Researchers, academics, and anyone writing with references.
Polished Mac-native options
Bear
Bear is a well-regarded Mac and iOS notes app with a markdown-flavored editor and a tag-based organization model instead of folders. It’s genuinely pleasant to write in, and it’s native rather than Electron, so it’s fast.
The catch for Obsidian refugees: Bear keeps notes in its own library rather than as .md files you own on disk. You can export to markdown, but day to day you’re not editing plain files. Sync across devices is a paid subscription.
Pros: Native and fast, beautiful typography, strong tagging, excellent iOS app. Cons: Not plain-file storage. Sync requires a subscription. Apple platforms only. Best for: People who want a polished writing app and don’t need file-level ownership.
Craft
Craft is another Mac-native option, built around nested documents and blocks, with a strong focus on presentation and sharing. It’s closer to Notion in feel than to Obsidian, but it’s fast in a way Notion isn’t.
Pros: Native, very polished, good sharing and publishing, offline-capable. Cons: Proprietary format rather than markdown files. Paid tiers for the useful parts. Best for: People who want documents that look good and get shared with others.
Apple Notes
Worth naming, because for a meaningful number of people it’s the honest answer. It’s free, it’s already installed, it syncs flawlessly across Apple devices, and it’s fast.
It is not markdown, and it doesn’t do backlinks in any real sense (it added links between notes, but that’s not a graph). If your Obsidian vault was really just a pile of notes you occasionally search, this covers it with zero setup.
Pros: Free, built in, best-in-class sync, instant. Cons: No markdown, no plain files, no linked-thought features. Best for: People who over-engineered their note-taking and want to stop thinking about it.
If you only wanted the editor
mdMD
We build mdMD, so read this section knowing that. It is not an Obsidian replacement, and it would be silly to pretend otherwise: there are no backlinks, no graph view, no tags, no plugins, and no vault.
What it is: a free, native macOS editor for markdown files. It opens a .md file in well under a second, shows raw source and rendered preview side by side, and renders Mermaid diagrams offline. It’s built with SwiftUI and AppKit rather than Electron, so it uses a fraction of the memory.
The reason it belongs on this list is that a good number of people searching for an Obsidian alternative are describing the editor problem, not the knowledge-base problem. If you set up a vault, wrote a hundred notes, and never once opened the graph, then what you actually want is something that opens markdown files quickly and gets out of the way.
Because Obsidian vaults are just folders of .md files, you can point mdMD at yours and start editing today. One caveat worth stating plainly: Obsidian’s own syntax extensions — [[wikilinks]], ![[embeds]], %%comments%% — aren’t part of standard markdown, and mdMD renders them as literal text rather than as links. If your notes lean heavily on wikilinks, that will annoy you. If they’re mostly ordinary markdown, you won’t notice.
There’s more detail on using it against an existing vault in editing Obsidian vault files without opening Obsidian.
Pros: Native and genuinely fast, free, split view, offline Mermaid rendering, edits your existing files in place. Cons: No backlinks, graph, or plugins. Doesn’t render Obsidian-specific syntax. macOS 15+ only. Best for: People who wanted a markdown editor and accidentally installed a knowledge base.
The short version
- You use backlinks and the graph daily: Logseq is the nearest equivalent, with an outliner twist.
- Sync is your problem: Joplin.
- You write papers or long documents: Zettlr.
- You want something polished and native, and don’t need plain files: Bear or Craft.
- You over-built it and want out: Apple Notes.
- You only ever wanted to open and edit
.mdfiles quickly: mdMD, free, macOS 15 or later.
Whichever way you go, your vault is a folder of plain text. That’s the whole reason switching is low-risk — try two or three against a copy of it and keep whichever one you stop thinking about.
