About Scalar
Scalar's mock server learns event-driven APIs while the reference UI picks up localization
Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.
