Xplorer Interface

Overview

Xplorer is a desktop application that runs collections and environments (Postman format) locally. It provides:

  • 100% Local - Zero Cloud: Your API keys, tokens, and secrets never leave your machine. No CORS issues, no cloud routing and no agents to configure. Test localhost and internal APIs directly without security risks.
  • API Spec Navigator: Browse and test APIs directly from OpenAPI/Swagger specs. Navigate schemas, view documentation, and build live requests.
  • OAuth 2.0 Support: Full OAuth 2.0 authentication with system browser integration. Supports Authorization Code, PKCE, and Client Credentials flows.
  • Zero Migration Effort: Run existing collections as-is, no changes needed
  • Enhanced Feedback: Pass/fail indicators in navigation tree and detailed output pane
  • Data-Driven Testing: Run collections with CSV or JSON data files
  • Enterprise Ready: Signed desktop application for macOS, Windows, and Linux

Key Differentiators

True Local Execution

As a true desktop app, Xplorer runs 100% local. Test localhost APIs and environments within your firewall directly. No worrying about CORS or runner agents.

Superior Test Feedback

Xplorer shows pass/fail indicators directly in the navigation tree, making it easy to see test results at a glance. The output pane provides detailed HTML reports with assertion details.

Data-Driven Testing

Easily run collections with different data sets using the CSV/JSON tab. Perfect for testing multiple scenarios without duplicating requests.

cURL Import

Quickly convert cURL commands to requests using the Import pane. Great for adding examples from API documentation.

API Spec Navigator

Open any OpenAPI or Swagger specification and instantly browse all endpoints. View complete schema documentation with reference traversal, build sample JSON payloads, select which fields to include, and go from spec to live request with one click. Perfect for API exploration and testing.

Simple Environment Handling

One active environment at a time keeps things simple. Environment variables are displayed in the Environment pane and update in real-time during execution. Drag and drop another environment file at any time to apply it.
