Wave Client brings free API testing inside VS Code
Wave Client is a REST tool that runs inside VS Code. It can send HTTP, WebSocket, and SSE requests, and it lets people organize requests into collections. Existing work can be imported from Postman and OpenAPI/Swagger files.
It supports environments, dynamic values such as dates and UUIDs, and several login methods including Basic, Digest, and OAuth2. It also includes response checks, request flows, and test suites for more advanced use. The tool is free to use and is intended to stay free; a future paid version for may be separate instead of turning the current product into a paywalled app.
Data stays on the user’s own device, with no telemetry or tracking.
