Constellation is an open-source, serverless, framework that simplifies geographically distributed API load testing
Constellation can simulate loads of up to 10,000 concurrent users from all across the globe. Tests can be of any duration, from minutes to hours or longer. Users can also see the results of their load test in an easy-to-read locally installed visualizer app.
With 26 regions to choose from, you can simulate real user-traffic to your API from around the world.
Powered by NodeJS and the Axios library, it is easy to script how users interact with your API.
You only pay the AWS charges stemming from the infrastructure spun up to run your test.
Use Constellation's visualizer to get insights about the performance of your API.
