Best self-hosted Notion alternatives: AppFlowy vs Outline

Di short answer

Self-hosted Notion alternatives dey fall into three groups. To pick di correct one, first decide which part of Notion you really dey use. If you want di Notion experience, with pages inside pages and database view, run AppFlowy. If you want fast team wiki with excellent search, run Outline. If you want di shortest way from fresh server to working workspace, run Docmost.

Two more tools dey show often for this search, and both answer different questions well. BookStack na di better choice when wetin you really need na structured documentation. Obsidian na di better choice when only one person dey use di workspace: you.

How dem compare

Dis na comparison of wetin each project documentation show say e fit do. E come from each project official documentation, published environment sample, and public compose file, wey dem check for July 2026. Dis no be report of one year for production on each project. Any limit wey dem state below come from the project own docs or repository, and the guide talk which one. Dis one matter because plenty comparisons like dis dey quietly make up the parts wey dem no check.

The four areas below na the ones people dey really ask about, for the order wey dem dey ask: databases and table views, real time collaboration, mobile access, and hosting weight.

AppFlowy: Notion dey closest, but licence get one catch

AppFlowy na the only project for here wey really copy Notion data model. Pages, boards, grids and calendar views all dey available. Desktop and mobile apps na native apps. The local-first design mean say app go continue to work when server no dey.

To self-host am, na git clone and compose file you need:

git clone https://github.com/AppFlowy-IO/AppFlowy-Cloud
cd AppFlowy-Cloud
cp deploy.env .env
docker compose up -d

Edit .env before you run that last command. FQDN and SCHEME set the public address. GOTRUE_ADMIN_EMAIL and GOTRUE_ADMIN_PASSWORD set the first admin account. If you leave GOTRUE_ADMIN_PASSWORD=password there, e go release a public server with admin login wey person fit guess easily.

Here be the catch, and na the most important fact for this post. AppFlowy Cloud don move to open-core model. The AppFlowy Cloud README talk say self-hosted Free tier get "One user seat (per instance)" plus up to three guest editors for pages wey you share. So, the version wey most people mean when dem talk "self-hosted Notion" na personal workspace with limited guests for the free tier. Paid self-hosted tiers remove that limit. Check the current tiers before you plan rollout for ten people.

Outline: best search, if you already get single sign-on

Outline na the strongest option for pure writing and reading experience among the group. Search dey fast and e dey really find things, the editor dey calm, and the structure na collections plus nested documents instead of database engine. Teams wey dey write plenty usually dey continue with Outline.

Outline need PostgreSQL and Redis, and the app dey listen on port 3000. E need two secrets, and the sample environment file dey show you exactly how to create them:

openssl rand -hex 32   # SECRET_KEY
openssl rand -hex 32   # UTILS_SECRET

Then set URL to your public HTTPS address, DATABASE_URL, and REDIS_URL. The thing wey dey surprise people na authentication. Outline no get built-in username and password login. Its own .env.sample talk about the third-party sign-in credentials say "at least ONE OF these is required for a working installation or you'll have no sign-in options". Google, Microsoft Entra, Slack, Discord and generic OpenID Connect (OIDC) provider na the supported options.

This one get real cost. If you no already dey run identity provider, self-hosting Outline mean say you must self-host one more service before Outline fit work at all. If you dey run one already, this one na feature, and Outline probably be your answer.

Docmost: di fastest one to stand up

Docmost na the newest among the three, and na the one wey need the least work to start. E get real-time collaborative editing, page trees, spaces, comments, plus built-in email and password accounts. So, you no need solve identity provider first.

The official installation page give four commands:

mkdir docmost
cd docmost
curl -O https://raw.githubusercontent.com/docmost/docmost/main/docker-compose.yml
openssl rand -hex 32

Put that hex string for APP_SECRET inside the compose file. Set APP_URL to the address wey you go really use. Replace STRONG_DB_PASSWORD for both places wey e appear. Then start am:

docker compose up -d
docker compose ps

Every service suppose read running. Open the address for browser. You suppose see the Docmost setup page, where you go create the first workspace and the first admin user. The stack na Docmost, PostgreSQL and Redis. The docs set the minimum at 2 vCPU and 4 GB of RAM.

One warning wey the docs repeat worth noting: the editor dey use WebSockets. If reverse proxy no pass WebSocket upgrade headers, the page go load, but edits from a second browser no go appear. Neither user go see any error. If you dey terminate TLS in front of am, a Traefik reverse proxy wey dey handle several apps for one box dey handle the upgrade correctly by default.

BookStack: when you need documentation, no be workspace

BookStack dey arrange content as shelves, books, chapters and pages. This fixed hierarchy na the main reason to use am. Nobody need invent structure, and even after one year, the wiki still easy to navigate. E get strong permissions, good editor, and e no dey complicated, just as infrastructure documentation suppose be.

Wetin e no get na database view or block-style editing, so e no be Notion replacement like the first three. BookStack need PHP 8.2 or newer and MySQL 8.0 or MariaDB 10.6 or newer. The project no publish im own Docker image; instead, e point to community images. The LinuxServer.io image na the one wey people use pass:

docker pull lscr.io/linuxserver/bookstack:latest

Because community dey maintain the image, pin one version instead of tracking latest, and read the image own documentation to know the variables wey e require.

Obsidian: e no be server app, and na dat be the point

Obsidian dey store plain Markdown files inside one folder for your machine. Server no dey, so you no get anything to self-host and nothing wey fit break for 3am. If na one person dey write notes, e dey faster pass every option wey dey above, and you fit trust say your files go outlive the software.

Na the sync part you go host. Options na paid first party sync service, one CouchDB instance wey dey power the community LiveSync plugin, or plain file sync like Syncthing or one WebDAV share. Real-time editing by many people no dey for the list. So if two people need use the same page at the same time, Obsidian no be the correct tool.

Databases and tables: where most alternatives stop

Na dis database dey determine the search. People wey miss Notion usually miss the database: table wey get typed fields, different views for the same rows, and filters.

AppFlowy get this feature, with grid, board and calendar views. Outline, Docmost and BookStack no get am. Dem get documents wey fit contain simple tables, but that one no be the same thing, because you no fit query the rows and no get another view for dem. If Notion database dey hold your work, AppFlowy na your only real option for this group, and you suppose test the free tier seat limit against your team size before you commit.

Hosting weight: wetin each stack really dey run

Docmost and Outline both dey run three containers: the app, PostgreSQL and Redis. Both fit run well for small VPS. BookStack dey run the app plus MySQL or MariaDB database, so e na the lightest of the four.

AppFlowy Cloud na by far the heaviest one. The compose file wey dem publish dey start nginx, MinIO for object storage, PostgreSQL with the pgvector extension, Redis, GoTrue for authentication, the AppFlowy Cloud service itself, an admin frontend, a worker, a search service, an AI service, and the web app. This na real database, object store and about ten containers. Plan enough memory for am, and read how Docker Compose services, volumes and networks dey work together before you start to edit that file.

Which one you suppose choose

One person, notes and drafts, and you no want server: Obsidian, with your own sync.

One person or small group wey want Notion-style databases: AppFlowy, but first check the free tier seat limit.

Team wey dey write plenty and already get Google Workspace, Entra or an OIDC provider: Outline.

Team wey want shared workspace wey go work this afternoon without identity provider: Docmost.

Infrastructure or product documentation wey many people dey read but only few people dey edit: BookStack.

Wetin fit spoil after install

Three problems dey cause most support threads for these projects, and all three na configuration issues, no be bugs.

The first one na app URL. Docmost APP_URL and Outline URL must use the address wey browser really dey use, including https://. Set am to localhost and put the app behind a domain, and login redirects go send users to machine wey no be their own.

The second one na WebSockets, as we don describe above. Collaborative editing go stop without any warning, even when the app still dey look healthy.

The third one na backups. All these apps dey keep their content for PostgreSQL or MySQL, no be for the files wey you fit see. So, copying the volume directory of database wey dey run no be backup wey you fit trust. Dump the database on schedule and store the dump outside the server, just as scheduled encrypted backups with restic dey handle any other stateful service. When you dey choose wetin else to run alongside am, the wider list of apps worth self-hosting this year fit help you check how much work one server suppose carry.

FAQ

Which self-hosted Notion alternative dey closest to Notion itself?

AppFlowy. Na the only one among these projects wey get real database concept. This means say typed fields fit get grid, board and calendar views over the same rows. Outline, Docmost and BookStack na document tools with page hierarchies. Dem dey excellent for documents, but dem no replace Notion database.

I fit self-host Notion itself?

No. Notion na commercial hosted product wey no get self-hosted edition and no published server component. Every option for this guide na separate open source project wey cover part of wetin Notion dey do. Migration na export and import, e no be lift of the same software.

These tools get mobile apps?

AppFlowy dey release native iOS and Android apps wey dey connect to your own server after you point dem to your instance. You dey use Outline and Docmost through mobile browser, and both dey work well for reading and small editing that way. Obsidian get full mobile apps, but na you go provide the sync. BookStack na responsive web application wey no get first party mobile app.

How much RAM I need for VPS?

Docmost document say minimum na 2 vCPU and 4 GB of RAM. Outline and BookStack dey around the same range for small team. AppFlowy Cloud different, because its compose file dey start around ten services, including PostgreSQL with pgvector and MinIO object storage. So plan for noticeably more memory and disk for there.

Outline dey usable without Google or Microsoft sign-in?

Yes, but e no dey work without some identity provider. Outline support generic OpenID Connect provider together with the named ones, so self-hosted OIDC server go work. Wetin e no support na plain local username and password. Its own environment sample talk say at least one third party provider must dey configured, otherwise the installation no get sign-in options.
