Needs adviceonJenkinsJenkinsGatlingGatlingLocustLocust

I am looking for a performance testing tool that I can use for testing the documents accessed by many users simultaneously. I also want to integrate Jenkins with the performance automation tool. I am not able to decide which shall I choose Gatling or Locust. But for me, Jenkins integration is important. I am looking for suggestions for this scenario.

I have to run a multi-user load test and have test scripts developed in Gatling and Locust.

I am planning to run the tests with Flood IO, as it allows us to create a custom grid. They support Gatling. Did anyone try Locust tests? I would prefer not to use multiple infra providers for running these tests!

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?
