Blitz vs Loader.io: What are the differences?

Developers describe Blitz as "Load testing for websites, web apps, and REST APIs". Build bulletproof, scalable solutions with Blitz - a simple and fun service for load testing web apps and APIs in the cloud. Blitz offers powerful yet simple capabilities including continuous monitoring, performance testing and remediation. Blitz enables you to instantly burst up to 50,000 concurrent users against your app in seconds from multiple points of presence around the world. On the other hand, Loader.io is detailed as "Simple Cloud-based Load Testing". Loader.io is a free load testing service that allows you to stress test your web-apps/apis with thousands of concurrent connections.

Blitz and Loader.io can be primarily classified as "Load and Performance Testing" tools.

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?

My choice would be Apache JMeter, It's free and opensource plus it comes with lots of plugins and extendability. Apache JMeter needs a small amount of a learning curve and a basic understanding of Network, Protocols (TCP/IP ports, HTTP(S) and REST/SOAP, etc.) for initial setup. But it doesn't require programming skills. it has a nice record and playback option. You can still carry on without the developer skillset if you follow these steps. 1. Take backup. 2. Start recording and interact with the application. 3. stop recording and save the test case. This will give you your test-bed, after this, after these steps, every time just do Restore from backup and then Playback and observer results.

If you have longer recordings then an understanding of how to modify the recorded scripts will come handy.

For some of the advanced features such as Configuring variables, implementing loops, throttling adding think time, and automating test scaling to the number of users will require good planning of test scenarios and a Developer experience but this is true for any tool (even loader.io)

Disclaimer: I work at k6, and I recommend you try our tool.

It might require some coding skills, but we support a few options to record a user session to autogenerate the load test. Read How to record a browser session with k6 OSS.

The k6 Cloud also supports recording a user session with a Browser Extension. Additionally, it provides a Test Builder UI to generate a load test for testing APIs.

If you have questions or need help, you can ask on Slack and the Community forum.

What are some alternatives to Blitz and Loader.io?
Apache JMeter
It is open source software, a 100% pure Java application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions.
Gatling
Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance. Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships JMS support.
Locust
Locust is an easy-to-use, distributed, user load testing tool. Intended for load testing web sites (or other systems) and figuring out how many concurrent users a system can handle.
k6
It is a developer centric open source load testing tool for testing the performance of your backend infrastructure. It’s built with Go and JavaScript to integrate well into your development workflow.
