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!

Optimizely

Optimizely is a great A/B testing tool for any size business. The Optimizely platform democratizes A/B testing through a simple interface, excellent training tools, easy implementation and low dependence on IT resources. Utilizing Optimizely I've been able to run robust experimentation programs with a variety of resources (acting as a 1-person team with limited access to IT resources as well as managing a team with high access to resources). Additionally, Optimizely is well-priced and positioned to be affordable for a variety of business sizes.

Pros

LaunchDarkly

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

Optimizely

  • Optimizely makes it extremely easy to setup almost any type of split or multi-variate testing experiment. It has a variety of test triggers types & many ways to segment incoming visitors.
  • I believe Optimizely's results dashboard is one of the best among split testing software. It allowed my team to get insights into the running of tests, like time to significance and a view of metric changes over time.
  • Optimizely is very easy to use for non-engineers. It has a powerful visual interface that allows marketers and advertisers to setup complex variations without 1 line of code.
  • In terms of documentation and implementation, I believe Optimizely is ahead of its competitors in terms of its focus on reliability and speed.

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.
steven mandzik | TrustRadius Reviewer

Optimizely

  • Assistance with on-boarding the tool as opossed to using a partner.
  • Dedicated training on the tool for internal business users both on the development and consultancy side.
  • Impression usage should be applied to running AB tests only - Development teams need to take some time to implement a winning variation and so using impressions to temporarily run a winning experience is not ideal.

Because it's an incredible and essential tool for my line of work as a conversion optimization specialist. Really couldn't do my job nearly as effectively without it. It's paid for itself many times over and I feel like I'm only beginning to unlock the tools potential.

I've heard great feedback from the Marketing and Development team who use the tool. I am not particularly great with code but find it easy to set up tests on my own and feel confident putting them live using the preview tool.

Web interface is nearly always available. Javascript snippet (which actually runs the test) is distributed on a CDN for near-constant availability.

They always are quick to respond, and are so friendly and helpful. They always answer the phone right away. And [they are] always willing to not only help you with your problem, but if you need ideas they have suggestions as well.

Ensure that your Optimizely JS script is loaded in the header of the page. The reason for this is that the DOM loads the page, and if you are changing elements on the page in your variation, Optimizely needs to know this before the page loads so that it can make those changes for your variation.

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.
steven mandzik | TrustRadius Reviewer

Optimizely

I think that Optimizely is more user-friendly than Adobe and Monetate, for example - Adobe is really suited for people with deep pockets and a distinct technical acumen that may not be suitable for a small business. Montetate is not user-friendly - even for seasoned marketers. Apptemize is a pretty great product but they killed their free product. Like Optimzely, they seem to be shooting for enterprise-level clients.

Optimizely offers excellent testing features and incredible technical support and training resources enabling non-technical teams most benefited by experimentation to truly own this function. Optimizely is easy to implement and use, has simple integration with other technologies making it a staple in our marketing technology stack. Finally, Optimizely continues to innovate around its core technology to add new features and capabilities to improve the overall experimentation process (such as acquiring Experimentation Engine in 2018). In a dynamic and ever-changing marketing technology landscape expect to continue using Optimizely in my marketing technology stack for many years to come.

Return on Investment

LaunchDarkly

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

Optimizely

  • Before using Optimizely, we were shooting in the dark with our design decisions. We'd make a change, then have to wait to see our user numbers drop over the course of a couple weeks, then roll back the changes. Our front end team would get frustrated with the wasted time, and try again. With Optimizely, our decisions are data-driven, morale doesn't take a hit, and we are always moving forward with our site.
