Nuclino review (2026): features, pros and cons, and what to check before you buy
Lightweight wiki and workspace with a free tier and SAML SSO plus audit log on the top plan.
Our take for buyers
Nuclino is a lightweight wiki and workspace from a Munich-based company, founded in 2015. It suits small teams that want a simple, fast wiki and teams that need SAML SSO at a lower tier than enterprise suites. G2 reviewers rate it 4.7 out of 5, although the pool is only 24 reviews, so treat it cautiously. Capterra shows 4.7 from 105 reviews.
Reviewers praise ease of use, simple design and clean markdown handling. The one complaint is that search handles typos poorly. Shortlist it for small teams with straightforward knowledge needs. Skip it for heavy workflow or approval processes, customer help centers and teams over 100 users, who need a custom conversation. Security features such as SSO and audit log sit on the top plan only.
