Stop sending API secrets to the cloud. 🛑 Meet Xplorer: The secure, 100% local-first API client. It runs your existing Postman collections instantly—ZERO migration needed. 🔒 No Cloud Sync 👤 No Accounts Required 🚫 No Telemetry ⚡️ Core Features Perpetually Free. Built for enterprise teams who need an "escape hatch" from cloud-forced tools. Your data stays on your machine. Period.
We work with many large enterprise customers (banking, insurance, healthcare) who use our open-source framework, Karate.
Over the last few years, we noticed a recurring concern among their security teams: developers were inadvertently syncing sensitive API collections, environment variables, and secrets to third-party clouds (like Postman’s) just to use the tool.
For many of these orgs, having internal API endpoints and auth tokens sitting on someone else's server is a compliance nightmare and a massive security vector. They need an "escape hatch" – a local-first developer tool. They wish to continue using collections that evolved over years, without disruption.
So we built Xplorer.
- The Security Premise: Xplorer is architected to be 100% Local. It is not a web-app wrapper that depends on the cloud, it is a true desktop app that uses your file-system.
- No Cloud Sync: Your collections and secrets never leave your machine.
- No Accounts: No login required. No identity tracking.
- No Telemetry: We don’t track usage. This is critical for air-gapped or high-security environments.
- The Migration Path: We know teams won't switch if they must rewrite or migrate anything. Xplorer runs Postman collections and environments as-is. There is no migration step. We emulate even JavaScript APIs so that your pre-request scripts and tests run without modification.
- Business Model (Transparency):We are building a sustainable business without monetizing user data.
Free: The core client (running collections, importing, scripting, local environment management) is perpetually free.
- Paid: We charge for features that solve "enterprise-scale" problems which includes OpenAPI and Swagger support, CI/CD and CLI runners, HTML reports, Git-friendliness (exploding collections into folders and files), and parallel execution.
If your security team has been clamping down on cloud-based API tools, or if you just want a simpler, local-first and cross-platform alternative to what you currently use, give Xplorer a try.
Next week, we release an update with deep OpenAPI and Swagger support. This is designed to get you from a spec to a live HTTP request in just a few clicks. One click to build a JSON payload and one click to bring up the API request playground (note the "Try It" button). Also, the best, human-friendly way to navigate those thousand-line YAML files you have, instead of relying on verbose generated HTML. Stay tuned !
Really enjoyed how fast everything loads. No background syncing, nothing slowing me down
