Best Python-native choice: tests are real Python code, highly flexible for complex user journeys and microservice workflows, easy to extend, distributed, and excellent for teams already living in Python

What would move Locust up

GPT Add more polished built-in reporting, hosted execution, and observability workflows so teams need fewer third-party pieces
Claude Ship stronger built-in reporting and metrics (percentile accuracy, trend analysis, richer exports) so results are decision-grade without bolting on Grafana or third-party dashboards
Gemini Better raw execution performance and lower memory usage per virtual user to match compiled languages.
Grok Optimize core engine for significantly higher RPS per instance to compete on extreme scale with async tools.
