Four things Load Impact is great at

Automated testing

Automated testing

Always be ‘ready to release’ great software with our Continuous Delivery load testing solution. Opt for quick installation with our CI plug-ins or full control with our API and SDKs.

API testing

Exercise the set of calls documented in your API exactly as your users would. Ensure that resources exposed by the API can be created, listed, updated and deleted appropriately under expected load.

Web app testing
