Scalar

Scalar belongs in the catalog because it is becoming one of the clearest modern API-tooling platforms built around OpenAPI as a system of record rather than an afterthought. The official pricing page now frames Scalar as one platform for docs, SDKs, governance, and API client workflows. That breadth matters. Scalar is not just a docs renderer and not just a codegen utility. It is trying to become a coherent API product layer that spans publishing, tooling, and standards discipline.

It also deserves inclusion because the pricing is public and specific. The checked official pricing page shows Free at $0, Pro at $24 per seat per month with a minimum of three seats, and Enterprise as custom pricing. Scalar’s own product docs also note that SDK generation is part of paid plans and is billed at $100 per month per language. That combination is useful for buyers because it exposes both the collaborative platform price and one of the most important add-on costs. In a category that often blurs platform and usage economics, Scalar is refreshingly direct.
