Collections & folders
Organize requests in a nested sidebar tree. Create folders, duplicate or delete items, and reload saved method, URL, headers, and body from each collection.
Native REST API testing for desktop
Send HTTP requests, organize nested collections, import Postman, Bruno, and OpenAPI specs, run test suites with JSONPath assertions, and inspect responses in a focused native app.
Designed for everyday API testing
Compose requests, interchange collections, run suites with assertions, and inspect JSONPath results without leaving the desktop app.
Environments & variables
Set a base URL per environment and share collection {{var}} variables across them. Configuration is stored as JSON with Save all and auto-save on exit.
Import & export
Bring collections in from Postman, Insomnia, Bruno, OpenAPI JSON/YAML, HAR, or a pasted cURL command. Export back out, or copy the current request as cURL.
OpenAPI 3.x
Import from a URL or local JSON/YAML file. Operations land in tag folders; path parameters become variables. Choose to update the current collection or create a new one.
Collection runner
Run named test suites with expected status codes, JSONPath assertions and captures, cancel support, and elapsed timing for each step.
Response inspection
Review status and headers with JSON pretty-print and syntax highlighting. Filter bodies with JSONPath and keep a per-request path history.
HTTP & HTTPS
Send GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS, TRACE, CONNECT, and LIST over HTTP or HTTPS. Set a per-request timeout; Send and Cancel run on a worker thread.
Light & dark
System-aware light and dark themes are available, with optional overrides through environment variables or CLI flags.
