You can use most JMeter plugins in OctoPerf. To install a plugin you simply need to upload it using the Files manager.
We will automatically download standard plugins right before running each test. Thanks to this you do not need to upload them to your projects unless your test is run from a location where it has no access to https://jmeter-plugins.org. Check the JMX import page for more info about this.
OctoPerf executes JMeter containers that already have the Standard set of plugins installed.
