Artillery vs Azure Load Testing
Answer Artillery is an open source, self-hosted protocol and API load tool from Artillery Software, scripted in JavaScript, TypeScript. Azure Load Testing is a commercial, vendor-hosted cloud load testing service from Microsoft, scripted in Java, Groovy. The practical split is the cost model: Artillery is open source, Azure Load Testing is commercial.
Curator verdict
Both cover HTTP, HTTPS. On recorded coverage Artillery is the wider of the two (5 protocols against 4), which matters only if your workload actually uses the extra ones. Budget and procurement usually settle Artillery against Azure Load Testing before any benchmark does. Run the same scenario on both before you standardize; the rows below only tell you what is true on paper.
