We performed a comparison between BlazeMeter and k6 Open Source based on real PeerSpot user reviews.
Find out what your peers are saying about Apache, Tricentis, OpenText and others in Load Testing Tools."It's a great platform because it's a SaaS solution, but it also builds the on-premises hosting solutions, so we have implemented a hybrid approach. BlazeMeter sets us up for our traditional hosting platforms and application stack as well as the modern cloud-based or SaaS-based application technologies."
"It has helped us simulate heavy load situations so we can fix performance issues ahead of time."
"For me, the best part is that we can graphically see the test result at runtime. It helps us understand the behavior of the application during all stages of the test."
"BlazeMeter's most valuable feature is its cloud-based platform for performance testing."
"The orchestration feature is the most valuable. It's like the tourist backend component of BlazeMeter. It allows me to essentially give BlazeMeter multiple JMeter scripts and a YAML file, and it will orchestrate and execute that load test and all those scripts as I define them."
"Using cloud-based load generators is highly valuable to us, as we can test from outside our network and increase load generation without having to upscale our hardware as much. The cloud load generator is there when we need it and is the feature we leverage the most."
"It has a unique programming dashboard that is very user-friendly."
"The baseline comparison in BlazeMeter is very easy, especially considering the different tests that users can easily compare."
"The standout feature of k6 is its strong focus on API performance testing."
"In terms of improvement, I would like to have the ability to customize reports."
"Lacks an option to include additional users during a test run."
"If the solution had better support and the documentation was efficient it would do better in the market."
"BlazeMeter needs more granular access control. Currently, BlazeMeter controls everything at a workspace level, so a user can view or modify anything inside that workspace depending on their role. It would be nice if there was a more granular control where you could say, "This person can only do A, B, and C," or, "This user only has access to functional testing. This user only has access to mock services." That feature set doesn't currently exist."
"My only complaint is about the technical support, where sometimes I found that they would not read into and understand the details of my question before answering it."
"The performance could be better. When reviewing finished cases, it sometimes takes a while for BlazeMeter to load. That has improved recently, but it's still a problem with unusually large test cases. The same goes for editing test cases. When editing test cases, it starts to take a long time to open those action groups and stuff."
"From a performance perspective, BlazeMeter needs to be improved...BlazeMeter has not found the extensions for WebSockets or Java Applet."
"The should be some visibility into load testing. I'd like to capture items via snapshots."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
