Released · VS Code extension

The local-first API client for VS Code.

Demo recorded from the extension installed in VS Code20 seconds · With sound

In the video

: A {{variable}} is autocompleted into the URL, the request is sent, and a 200 OK JSON response arrives.
: The Command Palette switches from local to staging, and the same request is sent again for a staging response.
: In the Collection Runner one request fails with 503, and Rerun Failed runs only the failed request again.
: Events from a text/event-stream response appear as they arrive.

Collections, environments, variables, history and the response viewer share one workspace inside VS Code.

Working now: Build, send and inspect requests inside VS Code. Environments and variables, collection runs, scripts, response compare, code generation, cURL/OpenAPI/Postman import and export, and WebSocket connections are supported.
Stays local: No login, no cloud sync, no telemetry. The only network traffic is the API requests you send. Requests and metadata are stored as local JSON; protected secret variable values go to VS Code SecretStorage.
Video: The window is a real recording of the extension installed in VS Code; captions, camera moves, the pointer and the soundtrack were added afterwards.
Status: Published on the VS Code Marketplace.
