$0

Postman rail

No account. No credit card. No expiry.

Your machine is the perimeter

✓API keys, tokens, and payloads never leave your device
✓No CORS headaches, requests originate from the desktop, not a browser
✓Test localhost and anything behind your firewall
✓No agents, proxies, or sidecars to install

02 · 100% Local, Zero Cloud

Your secrets stay on your machine

API clients that round-trip through a cloud service are a problem for regulated teams and anything behind a firewall. Xplorer is a desktop app, requests go from your laptop to the API and back. Nothing in between.

03 · Zero Migration Effort

Import your existing collections. Run them as-is.

Open the collections you already have. Xplorer runs their scripts and assertions as your team wrote them.

✓Postman collections, environments and every auth, incl. OAuth2 browser grants
✓Run folders and collections with CSV or JSON data files
✓Standard pm.test / pm.expect assertion syntax supported
✓Paste a cURL command and it becomes a request
✓Export any request back to cURL in one click

# drop in a cURL, get a request

curl -X POST https://api.example.com/v1/policies \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"holder":"acme","amount":5000}'

✓ Request created · headers parsed · body formatted

05 · Familiar Interface

No new UX to learn

If you’ve used a desktop API client before, you already know how Xplorer works. Panels on the left, request composer in the middle, response on the right. Everything where you expect it.

✓Dark mode and theme support out of the box
✓A command palette and shortcuts for every common action
✓Adjustable font size, great for demos and pair sessions
✓Syntax highlighting for JSON, XML, YAML, and more

Typical workflow

1 Open an existing collection, nothing gets rewritten
2 Edit requests, headers, or assertions in place
3 Commit back, or export to a Karate .feature file when you’re ready to automate

06 · Edit & Maintain

Preserve the test investments you already have

Xplorer respects the work already in your repo. Edit existing tests and collections in place, no forced rewrites, no lossy conversions. Migrate to Karate feature files when the team decides, not when the tool forces it.
