Overview
Requestly is a local-first, lightweight developer toolkit that combines an API client, HTTP interceptor, and API mocking capabilities. It is designed to help frontend developers, QA engineers, and support teams debug, mock, and test APIs without waiting for backend services. With a focus on data privacy, Requestly stores everything locally or syncs via Git, and offers self-hosting for enterprises.
LoadTester is a web-based distributed load testing tool that allows teams to run HTTP and API load tests in seconds from their browser or CI/CD pipeline. It provides live analytics, auto-stop thresholds, scheduled baselines, and regression detection. LoadTester handles all infrastructure, so teams can focus on results rather than setup.
