Laker is an independent software publisher that distributes its work openly through GitHub, reflecting a community-oriented approach to development in which source code, issue tracking, and collaboration are handled in public. The publisher's catalog currently consists of a single product, EasyPostman, a desktop application that combines two complementary capabilities commonly needed by developers and quality assurance engineers. On one side, EasyPostman functions as an API client in the style of Postman, allowing users to construct, send, and inspect HTTP requests, organize endpoints into collections, manage environments and variables, and review response data such as headers, status codes, and payloads. On the other side, it provides load testing functionality comparable to JMeter, enabling users to simulate concurrent traffic against an API or web service in order to measure throughput, latency, and stability under stress. By merging functional API testing and performance testing into one open-source desktop tool, EasyPostman addresses the typical workflow of backend and full-stack development teams, where engineers first verify that individual endpoints behave correctly and then validate that the system as a whole can handle realistic demand. The application fits naturally into categories such as developer tools, API development and testing, performance and load testing, and debugging utilities. Typical use cases include testing RESTful services during development, regression-checking endpoints after code changes, preparing load scenarios before a production release, and benchmarking infrastructure under configurable concurrency. Because it is open source, EasyPostman also serves users who prefer transparent, extensible tooling that they can audit, customize, or contribute to, making Laker's offering particularly relevant for teams that value cost-free, community-driven software in their testing pipeline.
