Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nuclino

  • There is no publishing layer, so a public help centre or versioned product documentation cannot live here and has to be maintained in a second tool.
  • The free plan is capped at roughly fifty items, which a real team passes within weeks, making it a trial rather than a usable tier.
  • Per user pricing means occasional readers who open a document twice a month cost the same as the writers who maintain it.
  • The editor is intentionally limited, with no databases, relations or page-level templates, so structured content such as a request register needs a different product.
  • Export options are limited to Markdown and PDF per item, so moving a large workspace elsewhere is a bulk conversion job rather than a supported migration.

Postman

  • Free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • Only 25 collection runs per month and 1,000 API calls/month on free tier
  • Removed local-only Scratch Pad mode in 2023, forcing cloud account creation and sync
  • Requires Postman account and internet connection for most features
  • Cloud-first architecture with mandatory syncing to Postman's cloud servers
  • No CI/CD integration or advanced security features on free plan

Answered from the vendors’ own pages

Nuclino: Can Nuclino publish a public documentation site?

No. Individual items can be shared by link, but there is no branded, versioned public site.

Postman: What is the cost of Postman?

Postman has a free plan limited to 1 user, 25 collection runs/month, 1,000 API calls/month. Team plans start at $14/user/month for Basic. Professional at $29/user/month, and Enterprise at $49/user/month.

Source
Nuclino: Where is the data stored?

In the European Union, by a company registered in Germany, which is usually the reason procurement shortlists it.

Postman: Can I use Postman offline?

Postman requires an internet connection to sync collections to the cloud. Since 2023, the Scratch Pad local-only mode was removed. Users must sign in with a Postman account, and collections sync to cloud by default. Offline work is possible but limited without cloud sync features.

Source
Nuclino: Does it handle translated content?

No. There is no locale model, so translations would be separate items kept in sync by hand.

Postman: Does Postman have team collaboration?

Team collaboration is not available on the free plan (limited to 1 user). Team plans start at $14/user/month and include shared workspaces, real-time collaboration, and team management features.

Source
Postman: What are the free plan limits?

Free plan allows: 1 user only, 25 collection runs per month, 1,000 API calls/month, and 1,000 mock server calls/month. No CI/CD integration or advanced security features.

Source
Postman: Does Postman work with other development tools?

Postman integrates with Git repositories, offers a Node.js runner (Newman) for automation, and connects with popular CI/CD platforms. Teams using git-native workflows may prefer alternatives like Bruno.
