The short version

  • Only Swagger UI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Paligo the Business plan starts at $15,000/year for only two authors, which is a high price floor compared with help-centre or wiki tools and prices out small documentation teams; Swagger UI only as good as the specification: a thin OpenAPI file produces thin documentation
  • They diverge on capability: Paligo covers Topic-based reuse, Swagger UI covers OpenAPI rendering.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

  • Internal API discovery across teamsnot Paligo

Where each one falls short

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

Paligo

  • The Business plan starts at $15,000/year for only two authors, which is a high price floor compared with help-centre or wiki tools and prices out small documentation teams
  • Topic-based, structured authoring has a real learning curve for writers used to free-form documents or Markdown, and onboarding time should be budgeted separately from the licence
  • Nexus Portal and Nexus Answers are separate paid products, so a buyer wanting hosted delivery or AI answers on top of authoring should expect additional annual cost beyond the base plan
  • Storage is capped per author (10 GB on Business) with additional storage or authors priced as add-ons, so a growing team's costs are not fully captured by the headline per-author price
  • Unlimited languages are only included on the Enterprise plan; Business is capped at two languages, which limits it for teams with more than a couple of target markets
  • Migrating an existing large documentation set into Paligo's structured content model is a real project, not a data import, and that migration cost sits outside the subscription price

Swagger UI

  • Only as good as the specification: a thin OpenAPI file produces thin documentation
  • Default presentation is dated compared with modern documentation tools
  • Large specifications render slowly and become hard to navigate
  • Try it out against production needs care with authentication and CORS, and is often disabled as a result
