Obsidian is a local markdown vault on your machine. Sync and Publish are paid cloud; you do not run an Obsidian server. Logseq is a local-first outliner with an AGPL client. Joplin is markdown notes with optional Joplin Server. AppFlowy can run AppFlowy Cloud on a VPS you operate. Anytype is local-first with an optional sync node. Standard Notes and Notesnook encrypt notes and publish self-hostable sync. SiYuan keeps a local kernel and can live on your disk or a host you run.
Local markdown vaults on your machine, plus sync servers you can operate, not another Notion workspace.
Self-hosted note-taking splits into two honest shapes. Local files: the app writes Markdown or a database on the laptop in front of you. A server you operate: a sync or API process on a VPS, the same operational idea as Umami or Grafana. Mixing those up is how people buy Obsidian Sync and think they "self-host." Toolradar data: Toolradar lists 10,429 published tools as of September 1, 2026, including 170 published note-taking tools, 84% of them free or freemium (38 free-only, 105 freemium, 27 paid).
That 84% looks friendly because many note apps have a free desktop cut. Most of the 170 are still cloud workspaces (Notion-class) or closed mobile apps. This guide keeps eight that are local-first or give you a sync server you can run. Notesnook is the eighth pick because that slug already appears as a toolSlug in seo-listicles-oss-1.ts, not because we invented a product. Notion and Evernote are out: you do not operate their stores.
Obsidian is closed source and still belongs here. The vault is folders of Markdown on your disk. That is self-hosted in the "your machine holds the files" sense, not in the "you run a multi-tenant notes API" sense. Logseq and Joplin give you files plus optional sync you choose (Git, WebDAV, Nextcloud, or a server). AppFlowy, Standard Notes, Notesnook, and SiYuan are the picks where a Docker compose on your VPS is a real path. Anytype sits between: local objects, optional node.
License hygiene still applies. These apps are not Redis or MongoDB, but if you put notes behind a stack that includes relicensed Redis or SSPL MongoDB, the same caveat you saw in analytics and monitoring applies. Do not call a source-available client "open source" without reading it. Anytype's client license is tighter than Logseq's AGPL.

Best for: People who want a folder of Markdown, a huge plugin list, and no notes server to patch
- Pro: The vault is local files. That is self-hosted in the laptop sense, not the VPS sense
- Pro: Free for personal use of the app; commercial use of the app has its own license terms to read
- Pro: Plugins, graph, and daily notes are why the name is the default PKM answer
- Con: Not a server you operate. Obsidian Sync and Publish are vendor cloud
- Con: Source is closed; you cannot audit the app the way you audit Logseq
Obsidian core app is genuinely free with no feature gating, every note-taking and knowledge management feature works without paying.
Watch out
No built-in collaboration beyond Sync shared vaults. Real-time multiplayer editing requires third-party solutions. Teams needing Google Docs-style collaboration will find Obsidian inadequate without significant workarounds
Logseq
AGPL local-first outliner with bidirectional links; sync is Git, files, or optional paid Logseq Sync.
- 5.0 on SourceForge (2 reviews)
- Starting price
- Free
- Free plan
- Free to use
Best for: People who think in bullets and want an OSI-licensed client with files on the machine
- Pro: AGPL-3.0 client, local-first, no paywall on core outlining, queries, or whiteboards
- Pro: Files (or a local DB, depending on version) live on your machine
- Pro: Free sync via Git, Syncthing, or a folder; official Sync is optional paid cloud
- Con: Outliner UX is a learning curve if you want long prose documents

- Pro: AGPL desktop, mobile, and CLI, plus a clipper, with E2E encryption available
- Pro: Sync through Nextcloud, WebDAV, Dropbox, or filesystem without a Joplin account
- Pro: Optional Joplin Server is the 'server you operate' path; read the server license for commercial hosting
- Con: UI looks older than Obsidian or AppFlowy
- Con: Joplin Server's license is not identical to the clients; check it if you sell hosting
Joplin's pricing is fair, especially for individual users.
- Starting price
- From $6/mo
- Free plan
- Yes
Best for: Teams that want docs plus boards without putting the workspace on Notion's servers
- Pro: AGPL-3.0, no feature gate on self-hosting the documented Cloud stack
- Pro: Documents, databases, and board views in one workspace
- Pro: Docker Compose path: this is a server you operate, unlike Obsidian
- Con: Younger than Notion; some automations still trail
- Con: Self-hosted AI needs your own API or local models
AppFlowy's pricing is generally fair, with a generous Free tier for small teams.
- Starting price
- From $9/mo
- Free plan
- Yes
Best for: Users who want offline objects and will accept a source-available client if the protocol is hostable
- Pro: Local-first: objects live on your machine, usable offline
- Pro: any-sync is MIT-licensed infrastructure you can host as your own node
- Pro: E2E encrypted sync when you do sync
- Con: Client apps use a source-available license (ASAL), not AGPL or MIT. Do not call the client OSI open source without that caveat
- Con: Hosted storage beyond the free allotment is paid
Anytype is one of the most generous free tiers in the note-taking space, local-first, end-to-end encrypted, and open-source with 1 GB of sync storage at no cost.
Watch out
Free tier limited to 1 GB network sync space
Standard Notes
E2E encrypted notes; self-host the server to unlock editors that the hosted free plan leaves plain.

- Pro: Rich editor, notebooks, tags, vault, clipper
- Con: Hosted free attachments are capped (about 50 MB a month, 10 MB per file); Pro raises that
- Con: Version history and app lock lean Pro on hosted
Notesnook's Free tier is incredibly generous, offering a vast array of features that many competitors reserve for paid plans.
Local Files Versus a Notes Server You Run
A local-first notes app stores the canonical copy on the device. Obsidian vaults are directories. Logseq graphs are files (or a local DB in newer builds). Joplin keeps a local profile and can sync. If the laptop works on a plane, the product works. Sync is a pipe, not the product.
A notes server you operate is optional extra process: Joplin Server, AppFlowy Cloud, Standard Notes server, Notesnook server, a SiYuan host, an Anytype node. That process is closer to Matomo than to a folder in iCloud. You apply updates. You take database dumps. You put TLS in front.
Self-hosted note-taking in this guide means at least one of those two: files on your machine, or a server you run. It does not mean "the vendor's free cloud tier." It does not mean Outline the wiki (that lives in the wiki guide). It does not mean Nextcloud-as-a-notes-app unless you are already committed to Nextcloud for files.
Why Notes Belong on Disk You Control
Notes hold drafts, journals, work secrets, and medical side channels people should not put in a random SaaS. A local vault you can zip and encrypt is a weaker legal story than "we never uploaded it." A sync server in a region you chose is the next-best story when you need two devices.
Vendor lock-in is the everyday risk. Closed formats and export buttons that strip links are how years of thinking become a PDF graveyard. Markdown on disk, or an export you have already tested, is the exit plan. Obsidian, Logseq, Joplin, and SiYuan are strong on portable text. Encrypted databases (Standard Notes, Notesnook) trade some portability for default encryption.
The category is 84% free or freemium in our September 1, 2026 snapshot, which hides paid Sync, Publish, and "unlock the editor" add-ons. Price the pipe. Obsidian Sync and Publish are paid cloud. Joplin Cloud is optional if you run your own sync. Read that split before you call the stack free.
Key Features to Look For
Canonical copy on your disk or your VPS (Essential)
If the only full copy lives in a vendor database, it is not in this guide. Files or a server you operate.
Say which shape you are buying (Essential)
Obsidian is local files. Umami-style notes servers are processes. Do not market Sync as self-hosting.
Export that survives the app (Essential)
Markdown, HTML, or a documented encrypted export. Test a round trip before you migrate a decade of notes.
License you can quote (Important)
AGPL and GPL clients are OSI open source. Closed Obsidian is still valid as a local vault. Source-available clients need a caveat, same habit as Sentry FSL.
Sync you can name (Important)
Git, Syncthing, WebDAV, Nextcloud, or a first-party server you run. 'The cloud' is not a name.
Encryption defaults (Nice to have)
Standard Notes and Notesnook encrypt by default. A plain Markdown folder does not, until you add disk encryption or a vault tool.
Mistakes to Avoid
- ×
Calling Obsidian Sync self-hosted. The vault is local files. Sync and Publish are paid cloud. You do not run an Obsidian server.
- ×
Picking Notion or Evernote for a self-hosted list. You cannot operate those stores.
- ×
- ×
Skipping an export test. Encrypted apps and outliners lose structure if you first export on the day you quit.
- ×
Calling Anytype's client open source without the ASAL caveat, or calling Redis and MongoDB open source if they appear in a notes-adjacent compose.
Expert Tips
- →
- →
If you want a notes API on a VPS, use Joplin Server, AppFlowy Cloud, Standard Notes, Notesnook, or SiYuan on a host you patch.
- →
Write 'local files' or 'server we operate' in the team README. The analytics and monitoring guides in this file use the same words on purpose.
- →
Encrypt the laptop disk. E2E on Standard Notes or Notesnook does not help a stolen unlocked machine with an open vault.
- →
Re-check licenses yearly. Notes apps are calmer than Redis, MongoDB SSPL, and Sentry FSL, but source-available clients still move.
The Bottom Line
Start with Obsidian if you want a local markdown vault and you accept a closed app. Start with Logseq or Joplin if you want OSI-licensed clients and files or sync you choose. Run AppFlowy, Standard Notes, Notesnook, or SiYuan when you want a server you operate. Use Anytype when local objects matter and you can live with a source-available client. Do not call vendor Sync self-hosting.
Frequently Asked Questions
Is Obsidian self-hosted?
What is the best open-source self-hosted notes app?
Do I need a VPS for notes?
No. Obsidian, Logseq, and a Joplin client work as local apps. A VPS is for Joplin Server, AppFlowy Cloud, Standard Notes server, Notesnook server, or a hosted SiYuan. That VPS is a server you operate, like Umami, not like a folder.
Why is Notesnook the eighth pick?
Notesnook is a published notes app with a self-hostable sync server, and the toolSlug already appears in seo-listicles-oss-1.ts. This list does not invent slugs.
Is Anytype open source?
The any-sync protocol is MIT and you can host a node. The Anytype client uses a source-available license. Quote that split. It is the same honesty we use for Sentry FSL versus OSI licenses on Grafana and Prometheus.
