Xplorer Features: 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

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.
