K6 vs ConvertKit

"Developer-Friendly Performance Testing Tool & Infrastructure" What do you like best about k6? -Excellent documentation and supportive blogs (and video content like the Office Hours series) content simplifies getting started with k6 -Developer-friendly -- Easy to install and get going in the CLI. Makes performance testing more accessible to not just a few, but all of those on an engineering team. This is so important as performance testing is no longer just an expectation of a single niche quality team because of limitations of licensing or knowledge of an antiquated tool. -k6 cloud -- So far, ensuring the ability to scale our tests beyond the resource of our machines has been reassuring. The analyses and comparison features between test executions is helpful so far. Looking forward to the continued work against this infrastructure platform. Review collected by and hosted on G2.com. What do you dislike about k6? -The user experience of using k6 with npm modules is not consistent with what you expect from typical development -xk6 extensions conceptually are great as a community is helping to build out a need. Just be cautious of utilization as they may not be supported long-term, though these extensions are featured in k6 documentation. Review collected by and hosted on G2.com. What problems is k6 solving and how is that benefiting you? k6 has made performance testing an accessible practice for engineering teams. It's a rather low barrier to entry (getting started with k6) , yet you can get as advanced as you with, customizing your scripts as you need to get the insights required. Because of this tool, I'm seeing engineering teams starting to take on the responsibility of knowing and testing the limitations of their APIs and tiers.

"K6-Game changer for API Load and Performance test" What do you like best about k6? It is developer friendly and easy to write load tests and has excellent documentation. Most importantly it is a straightforward K6 report that can tell where the performance issues are. We did a thorough analysis where we compared several tools/frameworks and we can tell with full confidence that K6 is much superior compared to other tools. These are some of the benefits: It is easy to install and start writing the first L&P test, code review It is great community support and excellent documentation Excellent Report and Integrates with NewRelic, CloudWatch if we decide to retire later it is easy to do because we can still run locally without being locked to one tool. I would call the K6 a modern L&P framework that can beneficial for any company. Review collected by and hosted on G2.com. What do you dislike about k6? I wish it had better support for HTTP protocols. It is awesome with API test but not so great with UI load test. Review collected by and hosted on G2.com. What problems is k6 solving and how is that benefiting you? Ensuring that API we develop performance well at Production. It is not a guessing game anymore. It is a data-driven decision.

What do you like best about k6? It's ease of use, readability and its fantastic set of constantly evolving features, paired with a vibrant community - which together with its good performance makes, to me, the best option for performance testing. And its extensibility as well... Tests are code, as they should. And readable code! Review collected by and hosted on G2.com. What do you dislike about k6? There is an extensibility /plug-in system but some integrations are still not covered… To complain about something, its only issue is that apart from the excellent readability of the tests, they still need to be written, so you need to know what you are doing- thank god- I still have a job. But give it time… (summary: tests needs to be written, haha) And the fact that you have to write in JavaScript - it would be fantastic to write in your own language such as C# as in my case :) Review collected by and hosted on G2.com. Recommendations to others considering k6: Check other options, make your own decisions. My criteria might not match yours. My decision points were the performance vs. features, mainly its code readability, how easy it is to define a real test, its open model, and extensibility. Review collected by and hosted on G2.com. What problems is k6 solving and how is that benefiting you? excellent, readable performance tests that evolve with the application, as code. One test source code fits all, so its simplicity is key.

I give ConvertKit a five out of five rating. Before I started using ConvertKit, I was using MailChimp, and I switched over to ConvertKit. It was a much more powerful tool, which gave me a lot more options for customizing my lists and reaching out to clients in a much more personalized manner. I chose to use ConvertKit because of its ability to interface with many of the other software programs that I was running for my health coaching business. And I also really liked that I was able to make various lists within ConvertKit based on my client's needs, so I could send some emails to people who had a certain need and other emails to people who had a different need. Not all emails had to go to everybody. I really liked the powerful software that ConvertKit came with that just gave me the opportunity to really be there for my clients in the exact way they needed me. When I first signed up for ConvertKit, I was able to choose a package that met my financial needs and the needs of my coaching business. And their references and help items were super great in walking me through all the steps that I was going to need. They have videos and tons of tutorials to help you get set up exactly the way that you needed. I always felt like if there was something that I wasn't sure how to do, I knew exactly where to go to find what I needed so I could get things set up just the way that was going to work best for me. If you're thinking about getting started with ConvertKit, I would highly recommend it. When I started using it after switching from a less powerful email management system, I truly thought, "Where has this been all of my life and why haven't I been using it before now?" It really is the way to go. As far as getting everything set up the way that you want. I feel like many of the other health coaches that I talked to felt the exact same way that once you switch to this more powerful program and see how it can be integrated with all of the other systems that you're using, it's worth the money, and it's worth the time to learn a new program or to get started with a program that is going to help you build your business successfully.

We have been using ConvertKit for 3.5 years now and we don't plan on going anywhere else! If you're looking for an email marketing platform that grows with your business and subscriber list, and that's straightforward to use as well as efficient, then you don't need to look any further than ConvertKit. My team and I find that it allows us to meet our goals quickly, deliver quality content, and all without overcomplicating things. Sometimes simple is best!

Overall, it's an ok tool. A lot of the glitches have cost me money (i.e. sending coupons to my list and excluding purchasers... only to find out prior purchasers still received the email). I've had requests for "discounts" from people who have received these emails after purchasing a product at full price. They are not happy. When people get stuck in sequences they go "cold"... then I end up sending a reengagement sequence before removing from my list and these people get very mad too... they have been expecting to hear from me and think that I don't send to my list regularly. Overall I really feel like just a number to ConvertKit. They don't care about my business and charge a FORTUNE. I think this product has hurt my business, cost me money and soured my reputation. In my opinion if they are charging such a premium price it really should be top notch and this really falls short in a lot of ways. I really wish I thought long and hard before signing up with them as it's going to be a NIGHTMARE to switch. I feel really "stuck" with using them and it's such a nightmare to manage at this point.
