6 Confluence alternatives, honestly compared.
Confluence is the enterprise wiki default for a reason: deep page trees, the Jira tie-in, and a marketplace of macros and apps for almost anything. But the ground has shifted. Confluence Cloud runs on AWS under a US-listed operator — data residency options exist, but the operator stays within reach of US jurisdiction — and on the self-hosted side, Server licences were discontinued with support ending in early 2024, leaving Data Center as the only on-premises path, positioned for large enterprises.
This guide compares six real alternatives for team documentation 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)
Wiki next to the work, or a separate silo?
Pages written far from the conversations that produced them go stale. Docs that live beside chat, tasks and calls stay current, because updating them doesn't require leaving the work.
- (02)
Can you actually self-host it?
With Confluence Server discontinued, self-hosting Confluence means the Data Center edition, positioned for large deployments. Check which tools on your shortlist run on your own servers at a size and price your team can realistically carry.
- (03)
How does editing feel in 2026?
Page forms and macros are one era; block editors with real-time collaboration are another. Your team writes in this tool every day — small editor friction compounds.
- (04)
Can you get your content out again?
Import is how you arrive; export is how you stay free to leave. Look at the formats each tool reads and writes before you pour years of knowledge into it.
- (05)
What does the bill do as you grow?
Per-user tiers, enterprise-only editions, and marketplace apps that are themselves priced per user across the whole site — model the total cost at next year's headcount, not today's.
The six 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 docs — conflict-free co-editing with per-block locking and presence, version history, comments, full-text search — living right next to the chat, tasks and calls of the same project, so a decision made in a call becomes a task and a documented page in the same place. DOCX files import, pages export to PDF and Markdown, and built-in viewers with OCR text extraction make even scanned PDFs searchable. Self-hosting goes all the way to air-gapped: it runs fully offline; calls use a self-hosted LiveKit server.
- Best for
- Teams whose documentation should live next to the conversations and tasks that produce it, and organisations that want the wiki on infrastructure they control.
- Hosting model
- EU cloud, private VPC, or self-hosted / air-gapped via Docker Compose.
- Honest caveat
- No macro or plugin marketplace — Confluence's app ecosystem has no equivalent here — and import/export is still maturing: DOCX in, PDF and Markdown out, no automated Confluence importer yet.
- 02(02)
Notion
The all-in-one docs-and-databases workspace
Notion turned documents, wikis and lightweight databases into one flexible block-based canvas, with a huge template ecosystem and a heavy AI push. For teams that want their knowledge base and their trackers in the same flexible tool, it redefined the category Confluence used to own.
- Best for
- Teams that want flexible docs plus lightweight databases in one polished cloud tool.
- Hosting model
- SaaS only.
- Honest caveat
- No self-hosting, and flexibility cuts both ways: big workspaces drift into disorder without real curation discipline, and the deeper you build on its databases, the harder it becomes to leave.
- 03(03)
Outline
The open-source knowledge base that feels modern
Outline is an open-source team knowledge base that actually feels like a 2026 product: fast, Markdown-friendly, with real-time editing and a clean reading experience. You can use the hosted cloud or run it on your own servers — exactly the option smaller teams lost when Confluence Server was discontinued.
- Best for
- Teams that want a modern, self-hostable wiki without an enterprise price floor.
- Hosting model
- Hosted cloud, or self-hosted (open source).
- Honest caveat
- Sign-in leans on an external identity provider (Google, Slack, OIDC), self-hosting means running Postgres and Redis yourself, and it is deliberately a wiki only — tasks, chat and calls live elsewhere.
- 04(04)
BookStack
The straightforward open-source wiki
BookStack is a free, MIT-licensed wiki that organises content the way a library does: shelves, books, chapters, pages. It is a simple PHP application that runs happily on modest hardware, which has made it a quiet favourite for internal documentation and IT teams.
- Best for
- Small and mid-sized teams that want dependable self-hosted documentation with minimal operations work.
- Hosting model
- Self-hosted (open source); managed hosting available via third parties.
- Honest caveat
- The fixed shelf–book–chapter hierarchy is opinionated, there is no real-time co-editing today, and the writing experience is plainer than modern block editors — by design, but plainer.
- 05(05)
SharePoint
The Microsoft 365 intranet workhorse
SharePoint bundles intranet sites, pages and heavyweight document management under the Microsoft 365 licence most enterprises already pay for. Its governance, retention and permissions machinery is genuinely deep, and for Office-centric organisations the integration is unmatched.
- Best for
- Microsoft 365 enterprises that need an intranet and document management with serious governance under one licence.
- Hosting model
- Microsoft cloud (SharePoint Online); an on-premises Server edition remains for large enterprises, but Microsoft's investment is cloud-first.
- Honest caveat
- Powerful but heavy: making SharePoint feel like a pleasant wiki takes real configuration work and admin ownership, and the day-to-day editing experience trails modern block editors.
- 06(06)
GitBook
Polished docs, wired to Git
GitBook is a documentation platform loved for product and API docs: Git sync, branch-based change requests, and publishing that looks good out of the box. If your documentation is curated content with an audience — customers, developers, the public — it shows.
- Best for
- Developer-facing product docs and public knowledge bases with a publishing workflow.
- Hosting model
- SaaS only — the old self-hosted edition was discontinued years ago.
- Honest caveat
- Built for curated, published documentation more than a sprawling internal wiki, and per-user pricing adds up once everyone in the company needs edit access.
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 live where the work happensEvery channel has docs right next to its chat, tasks and calls. The decision gets made, becomes a task, and gets documented in the same place — no separate wiki drifting out of date.
- An editor from this decadeA block editor with conflict-free co-editing — per-block locking and presence — plus version history, comments and full-text search. Writing a page feels like writing, not filling in a page form.
- Self-hosting without an enterprise floorThe same Docker Compose deploy works for ten people or the whole company — including air-gapped: it runs fully offline; calls use a self-hosted LiveKit server. No enterprise-only self-host tier.
- Search that reads your files tooFull-text search covers docs, and built-in viewers for PDF, DOCX, XLSX and PPTX extract text with OCR — so the knowledge trapped in scanned attachments becomes findable instead of invisible.
- Plain pricingCore is €10 per user/month, with optional add-ons — and no marketplace of per-user-priced apps quietly multiplying the bill as your site grows.
- Macros and appsConfluence's marketplace of macros and apps has no equivalent in Polybase. There is a REST API, an MCP server, GitHub and HubSpot connectors and Flows automation — but a macro-heavy Confluence setup will not map one-to-one.
- Import and export maturityToday: DOCX import, PDF and Markdown export. There is no automated Confluence importer yet — we offer migration assistance during onboarding, and automated importers are on the roadmap.
- 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.
- Native appsDesktop and mobile apps are available. You can also use the web app or installable PWA.
Choosing a Confluence alternative.
It depends on your binding constraint. A modern self-hostable wiki: Outline. Simple, dependable open-source documentation: BookStack. Already deep in Microsoft 365: SharePoint. Flexible cloud docs plus databases: Notion. Published product docs: GitBook. Docs living beside the chat, tasks and calls that produce them, self-hostable at any size: that is the case Polybase is built for — we're biased, so read the side-by-side comparison too.
Outline and BookStack are open source and self-hostable at any size. Polybase self-hosts too — including air-gapped setups, where it runs fully offline and calls use a self-hosted LiveKit server inside the same network. Notion and GitBook are cloud-only, and SharePoint's on-premises edition is a large-enterprise affair; Microsoft's momentum is firmly cloud.
Atlassian ended support for its Server products in early 2024. That leaves three honest paths: move to Confluence Cloud (AWS, under a US-jurisdiction operator — residency options exist, but the CLOUD Act reaches the operator), buy Data Center (still self-hosted, but positioned for large enterprises), or switch to a tool where self-hosting is a first-class option — Outline, BookStack, or Polybase.
There is no automated Confluence importer today — we say that plainly. Polybase imports DOCX and we provide migration assistance during onboarding; automated importers are on the roadmap. Going forward, your pages export to PDF and Markdown, so the knowledge you build in Polybase is not locked in.
No — there is no macro or app marketplace, and if your Confluence value lives in specific marketplace apps, check for equivalents before switching. What Polybase offers instead: a REST API, per-channel scoped API keys, an MCP server that works with Claude, Cursor and ChatGPT, GitHub and HubSpot connectors, and Flows for visual workflow automation.
Polybase Core is €10 per user/month, with optional add-ons such as Boards, Email, Tables and AI; self-hosted and enterprise deployments are custom — talk to us. Note that Confluence's sticker price is rarely the whole bill: marketplace apps are typically priced per user across the entire site. Whether Polybase beats your total depends on what else it replaces — a demo walks through your actual stack.
