Blitz vs Locust: What are the differences?

1. Programming Language: Blitz uses its own in-house built language called HTML++ for scripting load tests, while Locust allows users to write test scenarios in Python, which can be more versatile and familiar to Python developers.

2. User Interface: Blitz provides a user-friendly web interface for creating and running load tests, making it easier for non-technical users to set up tests. In contrast, Locust is designed to be more developer-centric, with a focus on writing test scripts using Python code.

3. Scalability: Blitz offers a cloud infrastructure that automatically scales up resources based on the load test requirements, allowing for testing with a high number of virtual users. On the other hand, Locust requires users to manage their own infrastructure, which may limit the scalability of load tests.

4. Community Support: Locust has a large and active open-source community that contributes to its development and provides support to users. In comparison, Blitz being a commercial product, has a limited community support system, with most support coming from the Blitz team.

5. Customization: Locust allows users to customize their load testing scenarios in detail by writing Python code, offering more flexibility and control over the testing process. Blitz, while providing a user-friendly interface, may restrict the level of customization available to users who prefer more advanced scripting options.

In Summary, Blitz and Locust differ in their programming language, user interface, scalability, community support, and customization options for load testing web applications.
