Teams look beyond Nuclino when a 50-item ceiling on the free plan starts to bite, when they want a wiki they can host on their own servers, or when single sign-on and audit logs sitting only on the top tier feels like a steep step. The usual moves are to a self-hosted open source wiki, to a workspace with databases, or to a larger structured wiki.
Short answer: Looking for a replacement for Nuclino? Docmost, Outline and Slab come first in our wiki software ranking. Challengers take places 1 to 3 here. Big brands follow in the order of our category ranking. Start with Docmost if you want a collaborative wiki you can run yourself and later buy support for. Each of the 11 alternatives sits in Best Wiki Software in 2026 and is described against Nuclino.
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.

Why buyers look past Nuclino
01
The free plan fills up quickly
Nuclino Free allows up to 50 items, 3 canvases and 2 GB of storage in total. Items are documents that the team edits together, counted across all workspaces. A small team documenting processes can reach 50 pages within weeks, and the next step is a per-user paid plan.
02
Admin and security features cluster on Business
Starter adds unlimited items, admin tools, publishing and 30-day version history. Sidekick AI, the audit log, team insights, advanced security controls, SAML single sign-on, a custom publishing domain and unlimited history all appear first on Business. A team needing only SSO therefore buys the whole upper tier.
03
Hosted only, with every member counted
Nuclino's security page describes a managed service with encrypted backups kept for up to 60 days, and the pricing page says a user is anyone who joins, guests and read-only members included. Upgrading moves the entire team to the paid plan, and we found no self-hosted edition on the pages we read.

What each one does differently

Docmost
Not stated by the vendor · Published
Docmost keeps a community edition under AGPL-3.0 that you run yourself, with unlimited spaces. Business adds a published per-seat price billed yearly with a ten-seat minimum, and a trial licence comes through a registration link. Its operator is Docmost, Inc. under Delaware law, so the vendor names a legal home but no country.
Switch from Nuclino if you want a collaborative wiki you can run yourself and later buy support for.
Outline publishes cloud plans in three bands by team size, up to 200 members, each with a trial button, which makes budgeting simple for a growing team. Larger organisations can install it themselves: a Community Edition without support, then Business from 10 users and Enterprise from 100. The code uses the source available BSL 1.1 licence.
Switch from Nuclino if you would rather pay by team-size band than count every guest as a user.
Slab, from Fallacy Labs, offers a free plan for up to ten users with 10 MB attachments and 90 days of history. Startup extends history to 365 days, while Business removes the limit and brings an uptime SLA. Enterprise starts at 100 users. The limit here is people rather than documents, so page counts do not run out.
Switch from Nuclino if a cap on people suits you better than a cap on pages.
AppFlowy combines documents with databases, projects, forms and a site builder, so a wiki is one use among several. The README states AGPLv3 and the vendor calls the model open core. Personal is free for one workspace owner with 100 MB of storage. Pro is billed per member and unlocks unlimited storage and 90 days of history.
Switch from Nuclino if you want databases and projects beside your pages and the option to self-host.
XWiki SAS of Paris sells Starter, Basic, Business and Enterprise, scaled by users, sub-wikis, support contacts and storage. Starter runs in the cloud with 25 users and one sub-wiki, so on-premise delivery begins one step higher. It carries a long history as an enterprise wiki, and every plan has a trial button.
Switch from Nuclino if you need sub-wikis, a European vendor and an on-premise route.
BlueSpice is the MediaWiki-based product of Hallo Welt! GmbH in Regensburg. It layers real-time collaborative editing, search across texts, titles, files and attachments, workflows, forms, permissions and subwikis over MediaWiki. Migration support covers Confluence, SharePoint and MediaWiki sources. Price is not shown on the pages we read, so budget needs a conversation.
Switch from Nuclino if your company needs permissions and workflows and wants help migrating.
Wiki.js is AGPL software that needs a team member comfortable with Node.js and PostgreSQL. Deployment options listed are Docker, Kubernetes with Helm, bare metal and one-click cloud templates. Editors cover Markdown, Visual and AsciiDoc, and sign-in works through OIDC, LDAP and SAML, the same standards Nuclino reserves for its top tier.
Switch from Nuclino if you have an admin who can run a database-backed server and want SSO built in.
Tiki treats the wiki as one part of a no-code framework, with trackers offering 45 field types and pages that can act as forms or templates. File galleries, blogs, forums and spreadsheets ship in the same install. A not-for-profit association in Ontario holds the trademarks. Managed hosting comes from a third party, TikiHosting.
Switch from Nuclino if your wiki needs to double as a tracker, form tool or intranet.
Wikidot is a hosted wiki farm incorporated in Delaware and registered in Toruń, Poland. A free account allows five sites of 300 MB each and shows ads. Pro Lite, Pro and Pro+ are sold per twelve months in euros including VAT, with storage from 30 to 200 GB. The home page shows a monthly price that differs from the plans page.
Switch from Nuclino if you want separate small wikis per project, billed yearly in euros.
MediaWiki is the software behind Wikipedia, published by the Wikimedia Foundation under GPL version 2 or later and free to download. You install and configure it, or use a hosting service. Extra functions arrive as extensions, so a corporate wiki means choosing, combining and maintaining several. Content structure is article-style, closer to an encyclopedia than to Nuclino's item boards.
Switch from Nuclino if you want a proven encyclopedia engine with a very large extension catalogue.
Gollum turns a Git repository into a wiki, so pages are plain text or markup files that you can also edit in any editor, with history you can view and revert. The repository states the MIT licence. Install goes through RubyGems, Docker or a Java war file, and Windows requires JRuby. No company or support plan appears.
Switch from Nuclino if your team already lives in Git and wants documentation stored as files.
You want to host the wiki yourself and keep support as an option
Docmost: Docmost's community edition is AGPL-3.0 and self-hosted with unlimited spaces, while Business adds a seat price with a ten-seat minimum. Enterprise features sit under a separate licence.
02
You prefer a free plan limited by people, not pages
Slab: Slab's free plan covers up to ten users with 90 days of history. Startup lifts history to 365 days and Business removes the limit.
03
You need SSO and have someone who can run a server
Wiki.js: Wiki.js sign-in covers OIDC, LDAP and SAML, and it runs on Docker or Kubernetes. Search needs PostgreSQL 17 or later.
04
You want a European vendor with sub-wikis and an on-premise route
XWiki: XWiki SAS is registered in Paris. Starter is cloud only with 25 users and one sub-wiki, and on-premise delivery begins one plan higher.
05
You want documentation stored as files in Git
Gollum: Gollum builds a wiki from a Git repository under the MIT licence, with page history you can revert. Install through RubyGems, Docker or a Java war file.
04
When Nuclino is still the right choice
Nuclino stays a fair pick when a small team wants a quiet, quick wiki and the free plan's limits are not a problem. Items, canvases and list, board, table and graph views arrive on every plan, real-time editing is included, and an API plus apps for web, desktop and mobile exist. Nuclino GmbH operates from Germany, and the security page lists ISO 27001, ISO 27018 and SOC2 as infrastructure standards. Check whether Starter covers you before moving.
05
What moving off Nuclino involves
01
Items and canvases export, but structure is yours to rebuild
Nuclino says you can export data in open and standardised formats, and the audit-oriented controls that restrict export live on Business. Export a sample workspace first and check how headings, links between items and canvas diagrams look in the target tool. Canvases may need redrawing.
02
Published workspaces and links need a plan
If you publish a workspace as a website or on a custom domain, list those addresses before you cut over, and set redirects or a notice. Also re-create groups, private workspaces and guest roles in the new tool, since member counting and permission models differ between wikis.
06
Questions about replacing Nuclino
6 answers
What does the Nuclino free plan include?
The pricing page lists up to 50 items, up to 3 canvases and 2 GB of total storage, with real-time collaboration, the list, board, table and graph views, integrations and an API. Starter lifts items and canvases to unlimited.
How long is Nuclino's version history?
Starter keeps 30 days of version history and Business keeps unlimited history. The pricing page shows no history for the free plan, so check the live comparison table before relying on it.
Is there a self-hosted wiki that replaces Nuclino?
Docmost, Wiki.js, Outline, XWiki, Tiki, MediaWiki, Gollum and AppFlowy all describe an install you run yourself. Licences differ: AGPL, BSL 1.1, GPL and MIT appear among them, so read the licence against how you plan to use it.
Does Nuclino offer single sign-on?
SAML single sign-on appears only on the Business plan, together with the audit log, team insights, advanced security controls and Sidekick AI. Wiki.js lists OIDC, LDAP and SAML sign-in in its self-run software.
Does Nuclino have a free trial?
Starter carries a 14-day free trial with no credit card required. The free plan itself is not time limited but is capped by item count.
Which alternatives name a European vendor?
XWiki is registered in Paris and BlueSpice comes from Hallo Welt! GmbH in Regensburg. Wikidot is registered in Toruń, Poland. Several others state no country, so ask before assuming where data sits.
