Karate Xplorer
Xplorer is a desktop app for working with APIs on your own machine. One window holds three rails, each picked from the activity bar on the left edge:
| Rail | What it opens | What you do there |
|---|---|---|
| Collections | Postman collections (v2.0, v2.1), environments and globals | Edit, send, run folders and collections, scripts, every Postman auth type |
| OpenAPI | OpenAPI 3.0 and 3.1, Swagger 2.0 (JSON or YAML, file or URL) | Browse operations and schemas, read the docs, try an operation against a server |
| Karate | A Karate project folder | Browse and edit features, run tests, read results and reports |
Everything runs locally. Xplorer sends nothing except what you start: your requests, OAuth sign-ins, Open URL, and on demand the update check and license sign-in.

Free and Premium

Xplorer is free. Premium adds the actions that run or generate tests from a spec or a project. Premium features are always visible in the app, marked with a ★; using one without a license opens the License pane.
| Rail | Free | Premium ★ |
|---|---|---|
| Collections | Everything: open, edit, save, send, run folders and collections with data files, environments, every auth type including OAuth 2.0 browser grants, scripts, cURL import, Copy as cURL, Export to Karate, run output and run history | Save report… of a run (HTML, JUnit, JSON) |
| OpenAPI | Open, browse, docs, schemas, samples, source view, search, Problems, Copy as cURL, Copy Path | Try It, Add to Collection, Export to Karate, Copy as Karate |
| Karate | Open a project, browse, edit and save, highlighting, completion, Problems, new project or feature, Copy Run Command, Open in IDE, open a report on disk, Copy failure | Runs from every entry point, re-run, re-run failed, saved run reports and run history |
Premium comes with an Xplorer license, Karate Agent, Karate IDE Pro or Ultimate. Karate IDE Plus does not include it. See Licensing.
File mode and project mode
A window works in one of two modes:
- File mode — loose collections, environments and specs. Runs stay in memory; nothing is written to disk.
- Project mode — open a Karate project, or a folder with a
pom.xml,build.gradleorkarate-pom.json, and that folder becomes the window's project root. Collections and specs listed for the project open with it, and Postman and Karate runs are kept as run history.
See Projects.
