7 Notion alternatives, honestly compared.
Notion made documents flexible and pleasant — and then the wiki quietly drifted out of date, because the talking happens in Slack, the meetings in Zoom, and the tickets somewhere else again. And when compliance asks where your internal knowledge physically lives, Notion has one answer: their cloud. As of this writing there is no self-hosted option.
This guide compares seven real alternatives for team docs and wikis. One of them is our own product; we say so on its card and apply the same honest-caveat rule to it as to everyone else.
Five questions worth asking before you switch.
- (01)
Where does your knowledge live?
An internal wiki is some of your most sensitive data. Cloud-only, or can you run it on your own servers — in your region, under your keys?
- (02)
Does the wiki live next to the work?
Docs in one silo, chat in another is how wikis go stale. The closer writing sits to the discussion that produced it, the longer it stays true.
- (03)
How structured does it need to be?
Some teams need pages; some need databases with typed columns and linked records. Tools differ sharply on the structured half.
- (04)
What are your exit options?
Markdown export, CSV export and open formats decide how hard leaving will be later. Ask before you pour three years of knowledge in.
- (05)
Who tends it on day two?
Every knowledge base needs a gardener — and self-hosted ones need an operator too. Budget for both, or the tool won't matter.
The seven contenders.
- 01(01)
Polybase
Our productThe sovereign team workspace
Full disclosure: Polybase is our product. Read this entry as the maker's perspective — the caveat below is as real as everyone else's.
Polybase gives every channel block-based documents — slash commands, conflict-free co-editing with per-block locking and presence, version history, comments — living right next to the chat, tasks, tables and calls of the same project. Knowledge stays where the work happens instead of drifting in a separate wiki, and the whole workspace runs as EU-region cloud, in your own VPC, or fully self-hosted including air-gapped setups. Core is €10 per user/month, with optional add-ons.
- Best for
- Teams whose Notion wiki drifts stale because chat, tasks and meetings live in other tools — and organisations that need a self-hosted knowledge base.
- Hosting model
- EU cloud, private VPC, or self-hosted / air-gapped (Docker Compose).
- Honest caveat
- A young product: Notion's editor and template ecosystem run deeper, SOC 2 and ISO 27001 are on the roadmap rather than held.
- 02(02)
Confluence
The Atlassian wiki, Jira's neighbour
Confluence is Atlassian's wiki — the long-standing default for engineering documentation, deeply integrated with Jira. It scales to very large organisations, and unlike most of this list it still offers a self-managed edition (Data Center) alongside Atlassian Cloud.
- Best for
- Jira-centric organisations that want documentation in the same vendor family.
- Hosting model
- Atlassian Cloud or self-managed Data Center.
- Honest caveat
- The Server edition is discontinued and Data Center targets large deployments. Day to day it remains a wiki — chat, tasks and calls live in other tools.
- 03(03)
Slite
Deliberately docs-only, for remote teams
Slite is a focused documentation tool for remote teams: a clean editor, a tidy knowledge-base structure, and AI-assisted answers on top of your docs. It deliberately does one thing well instead of trying to be an everything-app.
- Best for
- Remote teams that want a low-friction, docs-only knowledge base.
- Hosting model
- SaaS only.
- Honest caveat
- No self-hosting, and by design no chat, tasks or calls — the rest of your stack stays exactly where it is.
- 04(04)
Outline
The open-source team wiki
Outline is an open-source team wiki with a fast, Markdown-friendly editor, a clean structure and strong search. You can run it on your own servers or use the hosted cloud, and the open codebase keeps your exit options honest.
- Best for
- Teams that want a self-hosted, no-nonsense wiki and are comfortable operating it.
- Hosting model
- Self-hosted (open source) or Outline's hosted cloud.
- Honest caveat
- A wiki, not a workspace — and self-hosting means wiring up an external auth provider (Google, Slack or OIDC) plus the usual day-two operations.
- 05(05)
AppFlowy
The open-source Notion re-imagining
AppFlowy is an open-source Notion alternative built in Rust and Flutter — local-first, with an optional self-hostable cloud for sync and collaboration. It reproduces the Notion feel — blocks, databases, kanban — under your own control.
- Best for
- Individuals and teams that want the Notion model as open source, on their own terms.
- Hosting model
- Local-first apps; self-hostable AppFlowy Cloud for sync.
- Honest caveat
- A young project that moves fast; collaboration features and the ecosystem are still maturing compared to the incumbents.
- 06(06)
Coda
Docs that behave like apps
Coda blends documents with database tables, buttons and automations — 'docs as apps' — so a single doc can run a process, not just describe it. Its pricing is unusual in a good way: only Doc Makers pay; editors and viewers don't.
- Best for
- Ops-minded teams that want to build lightweight internal tools out of documents.
- Hosting model
- SaaS only.
- Honest caveat
- No self-hosting, and the power concentrates with the makers — docs can grow into apps that only a few people can maintain.
- 07(07)
Obsidian
Local-first notes you own outright
Obsidian is the local-first outlier: Markdown files on your own disk, linked notes, a graph view and a huge plugin ecosystem. It is a personal knowledge tool first — many teams use it, but through shared vaults and sync rather than a server.
- Best for
- Individuals who want durable, portable notes under their full control.
- Hosting model
- Local files on your device; optional paid sync, or bring your own.
- Honest caveat
- Real-time team editing, permissions and a shared source of truth aren't the model — it earns its place here as a different philosophy, not a drop-in team wiki.
Where Polybase wins — and where we don't win yet.
You are reading this list on our site, so here is the part vendors usually skip.
- Docs next to the conversationDocuments live in the channel where the discussion, tasks and calls already are — the decision gets written where it was made, and stays findable.
- A wiki you can self-hostEU-region cloud, your own VPC, or air-gapped self-host — your servers, your keys. Notion does not offer a self-hosted option today.
- Structured data includedNotion-style databases map to Polybase Tables — typed columns, formulas, lookups, linked records — living in the same channels as the docs.
- Plain pricingCore is €10 per user/month, with optional add-ons — instead of a docs bill plus a chat bill plus a meetings bill.
- AI with the full pictureBring your own model — Anthropic, OpenAI, Gemini or self-hosted via Ollama. The assistant sees docs, chat and tables as one context, and your content isn't used to train foundation models.
- Editor depth and templatesNotion's synced blocks and template ecosystem run deeper. Polybase covers the everyday core — blocks, comments, version history, file viewers with OCR, DOCX import, PDF and Markdown export.
- CertificationsNot certified yet — SOC 2 and ISO 27001 are on our roadmap. We answer security questionnaires and architecture questions today.
- Enterprise sign-onSSO/SAML/SCIM are on the roadmap; today sign-in is email/password and magic links.
- Importers and native appsNo guided Notion importer yet — we offer migration assistance during onboarding, with automated importers on the roadmap. Desktop and mobile apps are available.
Choosing a Notion alternative.
It depends on your binding constraint. Open-source self-hosted wiki: Outline or AppFlowy. Atlassian shop: Confluence. Docs that run processes: Coda. Local-first personal knowledge: Obsidian. Docs living next to the chat, tasks and calls that produce them, with a self-host option: that is the case Polybase is built for — we're biased, so read the side-by-side comparison too.
Outline and AppFlowy are open source and self-hostable. Obsidian is free to use and local-first, but not open source. Polybase is not open source either, but it can be fully self-hosted, including air-gapped deployments.
Notion exports Markdown and CSV, which most tools on this list can work from. In Polybase, documents come into the block editor and database CSVs into Tables; we offer migration assistance during onboarding, and automated importers are on our roadmap. Migrate the living documents rather than the whole archive.
Your internal knowledge base holds architecture decisions, processes and sometimes customer or HR context. Notion does not offer self-hosting today, so that data lives in US-jurisdiction cloud. Self-hosting — Outline, AppFlowy or Polybase — keeps it on your servers, under your keys, which simplifies GDPR and data-residency conversations considerably.
Polybase Core is €10 per user/month, with optional add-ons such as Boards, Email, Tables and AI. Whether that beats your Notion bill depends on what sits around it — if Notion plus Slack plus Zoom is carrying one team today, consolidation is where the saving comes from. A demo walks through your actual stack.
