The Best Obsidian Alternatives in 2026: Free, Open-Source and Self-Hostable, Ranked by Real Cost

Looking for the best Obsidian alternatives in 2026? The fastest free swap is Logseq — open-source, local-first, and it stores your notes as plain markdown files exactly like Obsidian, for $0. If privacy is your priority, Joplin adds real end-to-end encryption; if you want to run everything on your own server, SiYuan, Trilium and Anytype are genuinely self-hostable. The honest catch: Obsidian's app is already free, so most people don't leave over price. They leave because it's closed-source, or because they don't want to pay $4/month for Sync.

At TechRiseUps we compare a lot of self-hosted and open-source tools, and note apps are a category where the best Obsidian alternatives hide the most nuance in what "free" actually costs. So this comparison ranks each option by what you really pay to use it the way Obsidian users expect — full sync, offline access, and ownership of your files — not by the sticker price on the download button.

Why look for an Obsidian alternative?

Obsidian is fast, extensible and free to use, so the reasons to switch are specific rather than about cost. First, it is closed-source: the app is proprietary freeware, not open source, which rules it out for anyone who needs auditable code or wants to avoid depending on a single private company. Second, sync costs money — keeping a vault in step across devices through Obsidian Sync is $4/month on annual billing ($5 monthly), and while you can sync free with third-party tools, it is not built in. Third, the interface is a plain file manager by design: powerful once configured, but heavy for people who want structure, databases or collaboration out of the box. Note that since February 2025 Obsidian is free for commercial use too, so a business license is no longer a reason to leave. If you need open code, encrypted sync, or a tool you can host yourself, that is the real trigger.

The best Obsidian alternatives at a glance

Prices are entry-plan list prices as of July 2026. "Self-host" means you can run the app or its sync back-end on your own server.

Tool	Starts at	Open source	Self-host	Best for	Verdict
Logseq	Free	Yes (AGPL)	Files only	Local-first markdown, outliners	Closest free swap
Joplin	Free	Yes (AGPL/MIT)	Yes	Privacy + encryption	Best for private notes
SiYuan	Free	Yes (AGPL)	Yes (Docker)	Self-hosted block editor	Best self-host all-rounder
Trilium Next	Free	Yes (AGPL)	Yes (Docker)	Large personal knowledge bases	Best for deep hierarchies
Anytype	Free	Yes	Yes (own node)	Encrypted, local-first Notion feel	Best offline all-in-one
Standard Notes	Free	Yes	Yes	End-to-end encrypted writing	Best pure-privacy notes
Notion	Free / ~$10 user/mo	No	No	Databases + team collaboration	Best cloud all-in-one
Capacities	Free / ~$10/mo	No	No	Visual, object-based notes	Best polished cloud PKM

For reference, Obsidian itself is a free, closed-source app with optional Sync at $4/mo and Publish at $8/mo per site. Every tool below is judged against that.

Logseq: the closest free, open-source swap

Logseq is the tool most Obsidian users try first, and for good reason. It is free, open-source under the AGPL, local-first, and stores everything as plain markdown (or org-mode) files on your disk — so there is no lock-in and your notes outlive the app. The main difference is philosophical: Logseq is outliner-first, where every block is a bullet you can reference and zoom into, while Obsidian is document-first. That makes Logseq excellent for daily journaling, task management and networked thought, and slightly awkward for long-form prose. Backlinks, a graph view, PDF annotation and a plugin ecosystem are all present. Sync is the one gap — Logseq Sync is still in beta, so most people sync the folder with Git, Syncthing or a cloud drive, exactly as they would a free Obsidian vault. For a like-for-like, zero-cost switch, it is the default answer.

Joplin: the privacy-first pick with real encryption

If your reason for leaving is trust rather than features, Joplin is the strongest option. It is free, open-source, and the one mainstream note app with end-to-end encryption built in, so your notes are encrypted before they ever sync. You can sync for free through your own Dropbox, OneDrive, S3 bucket or a WebDAV server, or pay for Joplin Cloud from €2.99/month (about $3.20) if you would rather not wire that up yourself. Joplin stores notes in markdown, imports cleanly from Evernote and Obsidian, and ships mobile, desktop and CLI clients. The trade-off is polish: the interface is more utilitarian than Obsidian or Notion, and the plugin scene is smaller. But for encrypted, self-controlled notes at no cost, nothing else here matches it.

Run it on your own server: SiYuan, Trilium and Anytype

This is where an Obsidian alternative can actually beat Obsidian — true self-hosting, where your notes and their sync live on a server you control instead of a vendor's cloud. SiYuan is the best all-rounder: an open-source, block-based editor (Notion's feel with Obsidian's local files) that runs as a Docker container on any VPS, with optional paid cloud sync if you do not want to self-host. Trilium Next suits enormous personal knowledge bases — a hierarchical, self-hosted note tree with scripting and strong linking, again a single Docker container. Anytype is the most polished of the three: open-source and local-first with end-to-end encryption and the option to run your own sync and backup node. All three are free software; the only real cost is the server, and a $4–6/month VPS is plenty for a personal vault. If you have never done this, our guides to self-hosting apps on a VPS and the best cheap VPS hosting walk through the setup end to end.

Notion and Capacities: the polished cloud options

Not everyone wants plain files. If you would trade local-first ownership for databases, collaboration and a cleaner ramp, Notion is the obvious pick — free for personal use, then roughly $10 per user/month (Plus) and $20 (Business), with relational databases and team features Obsidian cannot touch. It is cloud-only and closed-source, the opposite of Obsidian's philosophy, but it is the best all-in-one workspace for teams. Capacities is an interesting middle ground: an object-based note app where every note is a typed object you can link and query, with a free tier and a Pro plan around $10/month. Craft and Tana sit nearby if you want polished, cloud-first personal knowledge management. For solo note-taking without a team, though, these are usually more tool than you need — see our Notion alternatives guide for the fuller list.

The real cost: Obsidian Sync vs doing it yourself

Here is the honest math, because "free app" hides where the money actually goes. Obsidian's app is free; the recurring cost, if any, is Sync at $4/month ($48/year) to keep devices in step, or Publish at $8/month to put a vault online. Every alternative changes that equation. Logseq, Joplin and the self-hosted trio all sync for $0 if you are willing to use Git, Syncthing or your own storage — so the cost is a little setup time, not a subscription. Pay for managed sync only when you value zero-config convenience: Joplin Cloud (€2.99/month) and SiYuan's cloud plan both undercut Obsidian Sync. And if you already run a server, self-hosting your notes adds no marginal cost at all. Switching purely to save money only makes sense if you were paying for Sync in the first place.

Which Obsidian alternative should you pick?

For most people, Logseq is the best all-round swap — free, open-source, plain markdown, and the smallest jump from Obsidian's mental model. If privacy is the point, choose Joplin for its built-in encryption and free self-controlled sync. If you want to own the whole stack, SiYuan (all-rounder), Trilium Next (deep hierarchies) or Anytype (polished, encrypted) all run on a cheap VPS for the price of the server alone. If you would rather have databases and team collaboration than local files, Notion is the better tool even though it abandons the local-first idea. And if the only thing bothering you about Obsidian is the $4/month Sync fee, remember the app is free — you can sync your existing vault with Syncthing and keep everything you already have. Whatever you choose, export a copy of your vault and test the importer before you commit.

FAQ

What is the best replacement for Obsidian? For a free, like-for-like swap, Logseq is the top pick: open-source, local-first, and it stores your notes as plain markdown files just like Obsidian. If you want encryption, choose Joplin; if you want to self-host everything on your own server, SiYuan or Anytype are the strongest options.

Why are people leaving Obsidian? The common reasons are that Obsidian is closed-source (proprietary freeware, not open source), that its sync feature costs $4/month, and that its bare file-manager interface feels heavy to people who want built-in structure, databases or collaboration. It is notably not about price: the app is free, and since February 2025 it is free for commercial use too.

Is there an open-source equivalent of Obsidian? Yes, several. Logseq, Joplin, SiYuan, Trilium Next, Anytype and Standard Notes are all open-source, and unlike Obsidian their code is auditable. Logseq is the closest match for markdown-based, local-first note-taking; the others add encryption or self-hosting.

Is there a self-hosted alternative to Obsidian? Yes. SiYuan, Trilium Next and Anytype can all run on your own server, usually as a Docker container on a VPS, so both your notes and their sync stay on infrastructure you control. Joplin can also sync through your own WebDAV or S3 storage. A $4–6/month VPS is enough for a personal knowledge base.

Is Obsidian 100% private? Your notes are stored locally on your device by default, which Obsidian cannot read. But the app itself is closed-source, so you cannot fully audit what it does, and Obsidian Sync — though encrypted — routes data through Obsidian's servers. For fully auditable privacy, an open-source, end-to-end-encrypted tool like Joplin or Standard Notes gives stronger guarantees.
