Director at SMKR Consultancy LLP

Provides global load simulations without managing infrastructure and offers built-in reporting features

BlazeMeter should improve or make available some features out of the box that JMeter requires customization for. The licensing cost is also a concern since BlazeMeter is not free like JMeter, which limits its use. Additionally, if there is no host in preferred locations such as some Asian or Middle Eastern countries, it might not be convenient to use BlazeMeter.

Supports web and mobile applications, very scalable, very stable, and wonderful support

There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The solution’s most valuable feature is the dashboard."

"The most valuable feature of the solution is its ability to run high loads and generate reports."

"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."

"Its most valuable features are its strong community support, user-friendly interface, and flexible capacity options."

"BlazeMeter's most valuable feature is its cloud-based platform for performance testing."

"The solution offers flexibility with its configurations."

"The stability is good."

"The on-the-fly test data improved our testing productivity a lot. The new test data features changed how we test the applications because there are different things we can do. We can use mock data or real data. We can also build data based on different formats."

More BlazeMeter pros

"Technical support is very good. I'm very satisfied with the assistance we've received so far."

"It can support both web applications and mobile applications, and in certain cases, it can also support testing of desktop applications or software-based applications. You can write web applications, mobile applications, and software-based applications."

Cons

"BlazeMeter should improve or make available some features out of the box that JMeter requires customization for."

"BlazeMeter has room for improvement in terms of its integration with GitLab, particularly in the context of CI/CD processes. While it has multiple integrations available, the level of integration with GitLab may need further enhancements. It is known to work well with Git and Jenkins, although the extent of compatibility with GitLab is uncertain."

"The product currently doesn't allow users to run parallel thread groups, making it an area that should be considered for improvement."

"We encountered some minor bugs, and I would like to have the ability to add load generators to workspaces without having to use APIs. We can't do that now, so we're beholden to the APIs."

"The reporting capabilities could be improved."

"BlazeMeter does not provide integration with the Aternity tool."

"I don't think I can generate a JMX file unless I run JMeter, which is one of my concerns when it comes to BlazeMeter."

"The scalability features still need improvement."

More BlazeMeter cons

"The solution is not easily scalable. If you want to extend the solution, you need to purchase a different kind of license. You also have to work with the IBM team to assist in scaling."

"There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies."

Pricing and Cost Advice

"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."

"My company has opted for a pay-as-you-go model, so we don't make use of the free version of the product."

"The overall product is less costly than our past solutions, so we've absolutely saved money."

"The solution is free and open source."

"I would rate the pricing a three out of ten, where one is very cheap, and ten is very expensive."

"The product pricing is reasonable."

"It is an averagely priced product."

"The pricing is manageable. It is not that big. Big companies won't mind the licensing costs."

More BlazeMeter pricing and cost advice

"It is much cheaper than Micro Focus LoadRunner. We need perpetual licenses. Support is included in the first sale. After that, you need to renew support every year."
