Blitz vs Loader.io: What are the differences?

## Introduction
Blitz and Loader.io are both performance testing tools that help developers and testers assess the performance of their applications under different load conditions. However, there are key differences between the two services that make them unique in their own right.

1. **Type of Testing**: Blitz focuses on stress and load testing by simulating a large number of concurrent users to analyze how well an application can perform under heavy loads. Loader.io, on the other hand, offers both load and stress testing as well as performance testing by providing detailed reports on response times and other metrics.
   
2. **Execution Environment**: Blitz provides a cloud-based testing platform where users can easily set up and run tests without the need for any additional infrastructure. Loader.io, on the other hand, allows users to run tests either on their own servers using the open-source loader agent or utilize Loader's cloud-based testing infrastructure.
   
3. **Monitoring Capabilities**: Blitz offers real-time monitoring and alerts during the testing process to help users identify performance bottlenecks and optimize their applications. Loader.io provides detailed charts and graphs post-testing to analyze the performance of the application under different conditions.
   
4. **Integration with CI/CD**: Blitz seamlessly integrates with popular continuous integration and continuous deployment tools like Jenkins, CircleCI, and Travis CI, allowing users to automate performance tests as part of their CI/CD pipeline. Loader.io also supports integration with CI/CD tools but may require additional configuration to set up automated tests.
   
5. **Customization Options**: Blitz offers a wide range of customization options for users to design and configure their tests according to their specific requirements, including setting up custom load patterns and scenarios. Loader.io provides a user-friendly interface but may have fewer customization options compared to Blitz.
   
6. **Price Structure**: Blitz offers a pay-as-you-go pricing model based on the number of tests and virtual users, while Loader.io offers a free tier with limited features and pricing plans based on the number of monthly test runs and virtual users.

In Summary, Blitz and Loader.io differ in their focus on testing types, execution environments, monitoring capabilities, integration with CI/CD, customization options, and pricing structures.

Needs advice

I have a team that is not heavy on programming skills. I am looking for a load testing tool that is easy to use. Preferably, the tool should be a record and playback tool without much programming. Also, the tool should be able to test APIs apart from web-based applications. What tool should I opt for?
