Features | Karate Xplorer — Local-First API Client

01 · No Limits. No Paywalls.

Free forever, without the fine print

Xplorer is genuinely free for every developer. No sign-in, no account, no telemetry, no “free tier” ceiling that nudges you toward a subscription.

✓No sign-in required — download, open, send requests
✓No artificial caps on requests, collections, or test runs
✓No telemetry and no analytics beacons phoning home
✓Core features stay free — forever

$0

Core features

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.

Bring the collections you already have. Xplorer reads standard formats directly and runs JS-style assertions the same way your team wrote them.

✓Import Postman collections and environments
✓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

# any LLM, editing your collection

$ claude mcp add xplorer \
    --transport http \
    http://localhost:8080/mcp

> "Add an auth header to every request in the
   ‘staging’ folder, then run the smoke suite."

✓ xplorer.collection.update · 12 requests
✓ xplorer.env.get           · staging
✓ xplorer.run               · 12 pass · 0 fail

04 · LLM Agent & MCP

Coming Q3 2026

Plug in any LLM. Edit and run in plain English.

Xplorer will expose an MCP server and a plain HTTP interface so Claude Code, Copilot, Cursor, or a local model can read, edit, and run your collections directly. Your artifacts never leave your machine — no cloud round-trip, no leaking secrets to a hosted assistant.

✓Works with any MCP-capable client or plain curl
✓LLM authors against your local artifacts — nothing leaves your machine
✓Describe the change; Xplorer applies it and runs the suite
✓BYO LLM — your tokens, your rate limits, your choice of model

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
✓Keyboard shortcuts for every common action
✓Adjustable font size — great for demos and pair sessions
✓Syntax highlighting for JSON, XML, YAML, and more

Typical workflow

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.
