Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The stability is good.""The product's initial setup phase was simple.""The extensibility that the tool offers across environments and teams is valuable.""The most valuable feature of the solution is its ability to run high loads and generate reports.""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.""BlazeMeter has allowed us to simplify and speed up our load testing process.""One thing that we are doing a lot with the solution, and it's very good, is orchestrating a lot of JMeter agents. This feature has helped us a lot because we can reuse other vendors' performance scripts that they have used with JMeter before.""The baseline comparison in BlazeMeter is very easy, especially considering the different tests that users can easily compare."

More BlazeMeter Pros →

"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process.""The standout feature of k6 is its strong focus on API performance testing."

Cons
"For a new user of BlazeMeter, it might be difficult to understand it from a programming perspective.""Integration with APM tools like Dynatrace or AppDynamics needs to be improved.""A possible improvement could be the integration with APM tools.""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.""If the solution had better support and the documentation was efficient it would do better in the market.""Integration is one of the things lacking in BlazeMeter compared to some newer options.""The should be some visibility into load testing. I'd like to capture items via snapshots.""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."

"One area where k6 could improve is by introducing a GUI similar to JMeter."

Pricing and Cost Advice
  • "The licensing fees are billed on a monthly basis and they cost approximately $100 for the basic plan."
  • "The solution is free and open source."
  • "The product isn't cheap, but it isn't the most expensive on the market. During our proof of concept, we discovered that you get what you pay for; we found a cheaper solution we tested to be full of bugs. Therefore, we are willing to pay the higher price tag for the quality BlazeMeter offers."
  • "The overall product is less costly than our past solutions, so we've absolutely saved money."
  • "It's consumption-based pricing but with a ceiling. They're called CVUs, or consumption variable units. We can use API testing, GUI testing, and test data, but everything gets converted into CVUs, so we are free to use the platform in its entirety without getting bogged down by a license for certain testing areas. We know for sure how much we are going to spend."
  • "My company has opted for a pay-as-you-go model, so we don't make use of the free version of the product."
  • "I rate the product's price two on a scale of one to ten, where one is very cheap, and ten is very expensive. The solution is not expensive."
  • "When compared with the cost of the licenses of other tools, BlazeMeter's license price is good."
