The short version

  • Only Scalar 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; Scalar it documents only what an OpenAPI document can express, so guides, authentication walkthroughs and conceptual pages need a second tool and a second navigation.
  • They diverge on capability: Paligo covers Topic-based reuse, Scalar covers OpenAPI driven reference.
  • Prices and features above were last checked on 1 September 2026.

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

Scalar

  • It documents only what an OpenAPI document can express, so guides, authentication walkthroughs and conceptual pages need a second tool and a second navigation.
  • The output is only as good as the spec, so an API with thin descriptions and missing examples produces a thin reference and the tool cannot compensate.
  • Deep visual customisation goes beyond the theme variables quickly, and matching an existing brand often means overriding styles against internal class names that can change.
  • Running the embedded client against a production API invites readers to send real requests, which means rate limits, test accounts and CORS configuration become your problem.
  • The open source renderer and the hosted platform advance at different rates, so a feature seen in a demo is not necessarily in the package you self host.

Answered from the vendors’ own pages

Paligo: Is there a free tier?

No, Paligo has no published free plan; pricing starts at $15,000/year for the Business plan.

Scalar: Can I use it without paying anything?

Yes. The renderer is open source and self hostable. The hosted platform is a separate paid product.

Paligo: Are Nexus Portal and Nexus Answers included in the base licence?

No, they are separate products priced from $5,000/year and $6,000/year respectively.

Scalar: Does it replace a full documentation site?

No. It covers API reference. Guides and concepts need a general documentation generator alongside it.

Paligo: How is AI translation priced?

Through prepaid, non-expiring token packages (5M, 10M or 20M tokens) rather than a per-seat fee.

Scalar: Will my reference go out of date?

Only if your OpenAPI document does. The reference is generated, so there is no second copy to forget.

Scalar: Does the embedded client send real requests?

Yes, from the reader browser. Plan for CORS, rate limits and a sandbox environment before publishing.

Scalar: What if my API has no OpenAPI document?

Then this is the wrong tool. Producing an accurate spec is the prerequisite, not an optional step.
