emRequest: REST and GraphQL API Client for VS Code, Cursor and Antigravity
A fast, lightweight REST and GraphQL API client that lives in your editor. Built by Emvigo Technologies.
Test APIs without switching to another app. Send a request, see the response, save it, and reuse it with different environments.
Features
- Request builder: method, URL, query params (kept in sync with the URL), headers, body (JSON, XML, text, form).
- Auth: Bearer token, Basic auth, API key (in a header or query).
- Response viewer: status, time, size, highlighted JSON, response headers. Copy it, or open it in an editor tab.
- Collections: save requests into named collections. Rename or delete them with the pencil or bin icons, right-click, or F2.
- History: every request you send is logged. Click one to open it again.
- Environments: variables like
{{baseUrl}} and {{token}} work anywhere in a request. Switch environments from the sidebar or the request tab.
- cURL: paste a cURL command to import it (it reads your clipboard), or copy any request as cURL.
- GraphQL: pick GraphQL in the Body tab to get a query editor and a variables box. Works with any GraphQL endpoint.
- Schema: click Fetch schema (it uses the request's own headers and auth), or Load file for a
.graphql or introspection .json file. The schema is saved per endpoint.
- Autocomplete and checking: field suggestions while you type, and unknown fields are underlined.
- Schema tab: browse types and fields with their descriptions, search, and click + to add a field to the query.
- Errors: GraphQL errors are shown in red even when the server answers 200 OK.
- More: an operation picker when the query has several operations, a Format button, GET or POST,
{{env}} variables inside the query and variables, and cURL import/export.
