Xplorer

Product Introduction

1. Xplorer is a secure, 100% local-first API client designed to execute existing Postman collections, environments, and tests without requiring migration or cloud synchronization. It operates entirely on the user’s machine, ensuring sensitive data like API keys and secrets never leave the local environment.
2. The core value of Xplorer lies in its commitment to data sovereignty and privacy, eliminating cloud dependencies while maintaining full compatibility with industry-standard tools and workflows. It provides enterprise teams with a frictionless, secure alternative to cloud-forced API testing platforms, prioritizing user control and offline functionality.

Main Features

1. Xplorer enables users to run existing Postman collections and environments instantly, supporting all standard formats and JavaScript assertion syntax without requiring modifications or migrations. This ensures seamless integration with established API testing workflows while preserving investments in existing test suites.
2. All data, including API secrets, payloads, and test results, remains 100% local to the user’s machine, with no cloud sync, telemetry, or external server interactions. The application handles CORS-free localhost testing and operates entirely within the user’s firewall for enhanced security.
3. The desktop app offers a familiar interface with dark mode, theme customization, keyboard shortcuts, and font-size adjustments, mimicking the UX of popular API clients to reduce learning curves. It supports direct editing of tests and collections in-place, allowing teams to maintain legacy tests indefinitely.

Problems Solved

1. Xplorer addresses the critical security risk of exposing API secrets and sensitive payloads to third-party cloud platforms by enforcing strict local execution and storage. This eliminates compliance concerns associated with cloud-based tools and mitigates risks of data breaches or unauthorized access.
2. The product targets enterprise development and QA teams that require full control over their API testing environments, particularly those bound by strict data governance policies or regulatory requirements. It serves organizations seeking to decouple from vendor-locked cloud ecosystems.
3. Typical use cases include securely testing internal APIs hosted on localhost or within private networks, maintaining legacy Postman collections without refactoring, and enabling offline API development in air-gapped or restricted environments. It also supports demo scenarios where internet access is unavailable.

Unique Advantages

1. Unlike cloud-based API clients, Xplorer operates without accounts, subscriptions, or internet connectivity, ensuring zero data leakage and uninterrupted offline functionality. It bypasses artificial limits on API requests or test runs imposed by competitors, offering perpetual free access to core features.
2. The application’s innovative local-first architecture combines Postman-compatible execution with native desktop app security, including signed builds for macOS, Windows, and Linux. It resolves CORS issues natively without requiring proxy configurations or cloud agents.
3. Competitive advantages include enterprise-ready deployment packages, perpetual free access to critical features, and compatibility with legacy test suites. Xplorer’s no-telemetry policy and avoidance of vendor lock-in differentiate it from tools that monetize user data or enforce mandatory upgrades.

Frequently Asked Questions (FAQ)

1. How does Xplorer ensure the security of API secrets? Xplorer processes all requests locally on your machine, never transmitting data to external servers or storing it in the cloud. Secrets remain encrypted within your device’s storage and are excluded from telemetry or diagnostics.
2. Can Xplorer run Postman collections without modifications? Yes, Xplorer supports all standard Postman collection formats, environments, and pre-request scripts natively, enabling immediate execution with zero migration effort. JavaScript-based assertions and variables function identically to Postman’s runtime.
3. Is there a paid version of Xplorer? Core features such as collection execution, local data storage, and environment management are perpetually free. Optional enterprise support and advanced team collaboration tools are available through separate licensing for large organizations.
