Scalar

Scalar is an open-source API client for Windows built around the OpenAPI format. Its offline-first design is intended for API work that does not depend on a continuous network connection. It is suited to developers and other technical users who work with APIs described through OpenAPI.

The software centers on using OpenAPI descriptions within a client application. This gives users an API-focused tool that starts with an OpenAPI definition rather than a general-purpose application. The available information does not identify additional modules or workflows, so Scalar is best understood through its offline-first API client role.

Scalar’s open-source license allows the software to be used under the terms of that license and distinguishes it from proprietary applications. Its Windows platform designation makes it relevant to users seeking an OpenAPI client for Windows. The combination of an open-source license and a Windows target places it in the developer tools category of a download catalog.

MirrorNest mirrors the official Scalar build directly on its own storage. The mirrored build is scanned for malware before it is published. This gives catalog users access to a stored copy of the official Windows build through MirrorNest. Scalar therefore fits the platform as an open-source Windows API tool distributed through a scanned mirror of its official build.
