LaunchDarkly

It is so much better than our old system which was a custom built system, always took very long to use, and required engineering resources to implement, adjust, update, etc. Now we can simply leverage LaunchDarkly. It is fast and easy. Anyone, not just engineers, can make updates. A particular use case for us is to modify traffic for tests. Turn up the participation or turn it down. Declare a winner. Now our analysts can directly do that as soon as they have the results. It is so much better!

VWO makes implementation and integration easy. They have done a great job to ensure the script does not heavily impact load times or page speeds. This was a very important aspect especially if you will be doing tests across multiple sites or products. Overall the UI is easy to learn and the support team is quick to address specific questions.

Pros

LaunchDarkly

  • Feature Flagging.
  • A/B Testing.
  • Giving any users access to edit feature flags.
  • Simple UI to interact with.

VWO

  • When designing A/B variations I can choose to either use the visual editor or to make the changes using code. I particularly like using jQuery.
  • VWO offers the ability to keep long term track of the performance of your goals.
  • I can easily identify recordings of users that dropped out of a funnel and watch those.
  • There is live chat to get support, with great response times and which is very helpful.
  • You are forced to create observations and hypotheses when creating a test, which is a great way to make sure that you are actually testing something worthwhile.
  • You can group tests together so that you can rule out interaction effects between tests that you are running at the same time.

Cons

LaunchDarkly

  • The messaging around features - especially those that turn on/off traffic for prod - could be clearer.
  • It's a little clunky to switch between projects & doesn't remember my default project for some reason.
  • I would like to make changes on my phone - not sure if they have a mobile app.

VWO

  • The user interface within VWO does take a bit of time to get used to, especially as it pertains to switching back and forth between tests. When running multiple experiments on a site at a time, a clear and succinct dashboard for everything in one place would be helpful (as opposed to needing to switch between A/B, multivariate, etc).

It's great value and we think we've ironed out all the major teething troubles. However, if we experience any more bugs or problems that significantly slow us down then we're seriously considering switching to Optimizely, which I haven't personally tested but have heard great things about from my CRO peers

I gave Visual Website Optimizer a rating of 8 because it is overall a great product to use. Setting up and keeping track of various tests is easy and straight forward. The only reason why this product is not rated higher is because the support documents online leave a lot of room for improvement.

While their online document support is lacking a simple email to their support team will almost always get responded to the next day. It has however taken more than one email to explain the problem to the support team till they understood the problem. The solution I was given also only half fixed the problem the rest I figured out on my own.

Alternatives Considered

LaunchDarkly

We built our own in-house solution, and that was what I compared it to. LaunchDarkly was faster, easier, and had a better UI than our internal tool.

VWO

We have used conversion.com and Lucky Orange. This is the 3rd CRO tool we have purchased. I think VWO is better than the other two. We also evaluated Optimizely and VWO was the clear winner in terms of price and functionality. The one thing that VWO lacked that Optimizely had was the ability to add custom dimensions to users for more granular business-specific testing segments.

Return on Investment

LaunchDarkly

  • Saved engineering time.
  • Increased speed to market for new features.
  • Enabled iterative development with easier feature flagging.
steven mandzik profile photo

VWO

  • We've been able to roll out new design patterns with confidence that short term revenue is not negatively effected.
  • We've had more wins than losses, as the company is just ramping up a testing strategy. We know percentage of wins will go down as we optimize, but VWO has been vital on making calculated steps along the way.
