Lightweight API client with built-in load testing and Git workspaces
Experience a blend of API debugging and JMeter-style load testing in one desktop tool, with local-first storage and a built-in MCP server for AI integration. EasyPostman, created by Laker, targets developers, backend engineers, and QA testers who need request inspection, SSE and WebSocket support, and thread-group based stress tests. The app supports Postman v2.1 import, runs headless via CLI for CI/CD, and stores collections in Git workspaces so teams can manage APIs as code.
What EasyPostman actually does for API development
EasyPostman combines request inspection and performance testing. It sends HTTP/HTTPS requests, handles Server-Sent Events and WebSocket flows, runs scripted pre-request and post-request logic, and imports Postman v2.1 collections and cURL commands. The tool also exposes a built-in Model Context Protocol server so AI clients can query and execute saved requests. These capabilities address debugging, validation, and automated interaction from one local desktop environment.
How it affects system resources and CI workflows
The tool runs locally with a bundled Java runtime and a headless CLI mode. Windows installers include a JRE so no separate Java install is required, and the CLI can execute collections and performance tests inside CI/CD pipelines. Performance testing uses thread groups and real-time metrics, which lets you run load scenarios on a desktop during development rather than on remote infrastructure.
Safety, data handling, and collaboration model
Local-first storage and Git workspaces prioritise on-device control over data. Collections, environments, and test data remain on the machine, and native Git workspaces let teams version API collections like source code. There is no account registration or cloud sync, so collaboration depends on your Git workflow. The developer provides the project as open source under Apache-2.0.
Who can operate it without deep tooling expertise
The tool suits developers and QA who understand requests and basic scripting. It exposes scripting for assertions and request lifecycle hooks, plus a Swing-based desktop UI and headless runs for automation. Casual users can import Postman collections, but effective use of performance tests and MCP integration assumes familiarity with thread-group concepts and Git-based collaboration.
Clear technical match for developers and testers needing local control
EasyPostman is a suitable tool for engineers and QA teams who want an on-device API client that also runs JMeter-style load tests and stores collections in Git. One trade-off is that collaboration relies on Git workspaces rather than an integrated cloud service. Keep CI runs in headless CLI and run stress tests during off-peak hours to avoid interfering with developer machines. The app performs reliably for local API development and testing.
