Confluence alternatives: 11 knowledge base tools compared

Confluence alternatives are sought by teams whose wiki has outgrown anyone's ability to find things in it, and by those without Jira who inherited it anyway. Smaller teams move to a faster, search-led internal wiki; organisations that want control move to open source; support teams move to a dedicated help centre.

Short answer: The first three alternatives to Confluence in our knowledge base ranking are XWiki, Outline and Archbee. Where a category has smaller vendors worth recommending, they occupy the first three places and the big brands come below them. Choose XWiki if you need Confluence-scale structure but want open source and control of the servers. Every one of the 11 products below comes from Best Knowledge Base Software in 2026, with a note on how it departs from Confluence.

Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.

Confluence

#12 of 20 in our knowledge base ranking

  • Pricing: Free to 10 users; paid per user per month, published
  • Established in: United States

Why buyers look past Confluence

  1. 01

    Pages pile up faster than they are tended

    The characteristic Confluence problem is not missing content but thousands of pages nobody can find and nobody dares delete. Spaces and macros make adding easy. Bulk archiving, page analytics and admin insights, the tools for tending a large wiki, are listed by Atlassian as Premium features, so on Standard the curation is manual and the sprawl keeps growing.

  2. 02

    Finding things costs extra

    A knowledge base is judged on how fast people find an answer. Atlassian lists site, space and page analytics only on Confluence Premium, at USD 10.44 per user per month against USD 5.42 for Standard. Slite and Slab were designed around search first, and Slab includes unified search across connected tools on every plan, the free one included.

  3. 03

    Without Jira, the reason is gone

    Confluence is bought almost entirely because Jira is already there, and the link between a ticket and its documentation is worth something real. A company that does not run Jira, or whose non-engineering staff never open it, pays per user for an integration it does not use.

What each one does differently

XWiki

France · Published

XWiki is built as a Confluence replacement, with structured pages and fine-grained rights. The difference is ownership: the code is open and it runs on your servers or theirs at the same subscription tiers. The Confluence migration toolkit is included free on Business and Enterprise plans; the Pro apps start at Basic.

Switch from Confluence if you need Confluence-scale structure but want open source and control of the servers.

Outline

United States · Published

Outline is open source with the best editor among the open options, run on your own infrastructure or bought hosted. Hosted pricing is by team size, not per seat: USD 10 per month for 1 to 10 members, USD 79 for 11 to 100, USD 249 for 101 to 200, with single sign-on and audit logs on every plan.

Switch from Confluence if you want open source without accepting a worse writing experience.

Archbee

Romania · Published

Archbee publishes documentation portals with custom domains and a GitHub integration, and it charges for team members, not readers. Growing starts at USD 80 a month and Scaling at USD 350, both with unlimited readers and spaces, after a 14-day trial. It is a portal publisher, so there is no Jira link.

Switch from Confluence if the wiki mainly feeds public product documentation with many readers and few writers.

Where Archbee stands: place 10 of 20 in the knowledge base ranking →

Slite

France · Published

Slite assumes people ask questions instead of browsing: its Ask feature answers from your documents, capped at 30 questions per seat a month on Basic. Basic is listed at USD 10 per user per month billed yearly, Pro at USD 20 adds search across connected tools, and there is a 14-day trial but no free plan on the pricing page.

Switch from Confluence if staff complain they cannot find anything and nobody depends on the Jira link.

Nuclino

Germany · Published

Nuclino opens instantly and keeps its structure deliberately shallow: pages and links, with no space hierarchy or macros to maintain. Its free plan is capped at 50 items and 2 GB. SAML single sign-on, the audit log and advanced security controls sit on the Business plan, so it gives up Confluence's organisational depth.

Switch from Confluence if a small team wants writing to take under a minute and needs few restrictions.

Slab

United States · Published

Slab searches Slack, Google Drive and other tools alongside its own pages, accepting that company knowledge is scattered. Unified search is on every plan. It is free for up to 10 users, then USD 6.67 per user per month billed annually on Startup and USD 12.50 on Business; full users are billed, guests are limited per user.

Switch from Confluence if your knowledge already lives in several tools and will never all be moved.

Our knowledge base guide puts Slab at 9 of 20; read why →

BookStack

United Kingdom · Published

BookStack replaces spaces and page trees with books, chapters and pages, a structure people grasp without being taught. It is free, MIT licensed and self-hosted on PHP and MySQL, so content sits in a database you control. The editor is plain, with an optional Markdown mode, and you run the server.

Switch from Confluence if licence cost must be nil and someone can administer a server.

Our knowledge base guide puts BookStack at 7 of 20; read why →

GitBook

France · Published

GitBook treats documentation as a repository with review before publishing, syncing with GitHub or GitLab where Confluence links to Jira tickets. Pricing is per published site plus users: Premium is USD 65 per site per month billed annually, Ultimate USD 249, each with USD 12 per user per month on top.

Switch from Confluence if the documentation is written by the engineers who write the software.

Document360

United Kingdom · On request

Document360 is a customer-facing knowledge base, not an internal wiki: article-level analytics, version history and scheduled review dates keep a help centre from rotting. It no longer lists flat tiers; the price is quoted from team accounts, workspaces, languages and security needs, after a 14-day trial with all features.

Switch from Confluence if you have been using Confluence to publish help articles to customers.

KnowledgeOwl

United States · Published

KnowledgeOwl prices by the knowledge base and the author, not the user: Basic is USD 100 a month with one author and one knowledge base, extra authors cost USD 25 and extra bases USD 50. Readers are unlimited, private and public bases are supported, and there is a 30-day free trial.

Switch from Confluence if a few people write and many staff or customers only read.

Check KnowledgeOwl in the ranked list (1 out of 20, knowledge base) →

Helpjuice

United States · Published

Helpjuice sells a flat monthly knowledge base instead of per-seat pricing: USD 249 for up to 30 users, USD 449 for up to 100 with SSO and the AI suite, USD 799 for unlimited users. It hand-builds the design on signup and has a free 14-day trial, but no free tier.

Switch from Confluence if you want a branded, flat-priced knowledge base and not a per-user bill.

Our knowledge base guide puts Helpjuice at 11 of 20; read why →

When Confluence is still the right choice

Confluence earns its keep in a company already running Jira, where linking a ticket to its documentation is the whole reason to have it. Spaces, permissions and macros handle organisational complexity that the lighter wikis cannot, it is free for up to 10 users, and Standard is listed at USD 5.42 per user per month. If somebody is given the job of curating it, most of what drives people away becomes manageable.

05

What moving off Confluence involves

  1. 01

    Check what an import does to macros

    Confluence pages lean on macros, and those are the part least likely to survive a move. XWiki includes its Confluence migration toolkit free on Business and Enterprise plans; elsewhere, export a sample space first and see whether images, tables and links between pages arrive as working content and not as plain text.

  2. 02

    Permissions will flatten

    Space and page restrictions are a real Confluence strength, and lighter tools such as Nuclino do not offer granular permissions. Identify which spaces are genuinely restricted, for instance HR or legal, and confirm the target can keep them private before anything is moved.

  3. 03

    Do not carry the sprawl across

    The pile of unfindable pages is the reason for leaving, so migrate selectively. Move spaces still being edited or read, name an owner for each, and keep the old instance available for reference. Decide separately how Jira tickets will point to documentation afterwards.

Questions about replacing Confluence

5 answers
What is the best open-source alternative to Confluence?

XWiki is the closest match: it was built as a Confluence replacement, has an importer, and offers fine-grained rights. Outline has the nicest editor of the open-source options, and BookStack is the simplest to understand. All three can be self-hosted.

Is there a Confluence alternative with better search?

Slite answers questions from your documents, and its Pro plan at USD 20 per user per month billed yearly also searches tools such as Slack, Jira and Google Drive.

Slab includes unified search across connected tools on every plan, including the free one for up to 10 users.

Should we leave Confluence if we still use Jira?

Probably not without a strong reason. The connection between a Jira ticket and its documentation is the main argument for Confluence, and it is a legitimate one. Appointing someone to curate the existing wiki addresses the sprawl without giving that link up.

Can a Confluence alternative also run a customer help centre?

The internal wikis, such as Nuclino, Slite and Slab, are not built for that. Document360, Helpjuice and KnowledgeOwl are dedicated help-centre products; Document360 adds article-level analytics and Helpjuice reports failed searches. GitBook publishes good-looking public documentation for engineering-led teams.

How much does Confluence cost compared with its alternatives?

Atlassian lists Confluence as free for up to 10 users, Standard at USD 5.42 and Premium at USD 10.44 per user per month.

Slab's Startup plan is USD 6.67 per user billed annually, Slite Basic is USD 10 billed yearly, and hosted Outline is USD 10 per month for a team of up to 10.
