Chose Optimizely Feature Experimentation
I wasn’t part of the team that selected Optimizely, but its integrations with other tools were a big plus for us in making our decision. It was more expensive, however.
Chose Optimizely Feature Experimentation
We have not used any other similar tools, we evaluated both Kameleoon and VWO. With the combination of price, features, and expandability, we moved forward with Optimizely Feature Experimentation.
Chose Optimizely Feature Experimentation
Google optimize is great that it is an add on to an existing Analytics implementation, but only has a web version. Optimizely has the SDK so better option for testing new features
Chose Optimizely Feature Experimentation
We selected Optimizely as it was easy to use/understand, had clearly defined SLAs for keeping the platform up and was regarded as resilient within the industry. We needed something at our point in our experimentation journey that could be used for Product testing at scale and …
Chose Optimizely Feature Experimentation
Optimizely Feature Experimentation has similar features to Amplitude. As a matter of fact it looks like Amplitude copied Optimizely. However, Amplitude did not mimic the nomenclature issues.
Chose Optimizely Feature Experimentation
When Google Optimize goes off we searched for a tool where you can be sure to get a good GA4 implementation and easy to use for IT team and product team.

Optimizely Feature Experimentation seems to have a good balance between pricing and capabilities.
Chose Optimizely Feature Experimentation
In other companies, all of the feature flag controls were done locally and it got messy after a while. There was no much control on who was doing what. With Optimizely Feature Experimentation, it is clear what feature flags are enabled and which ones are not. It is easier to …
Chose Optimizely Feature Experimentation
not too much experience on that to answer this question
Chose Optimizely Feature Experimentation
There is a lot more flexibility with Optimizely once you have customized the implementation and better tools.
Chose Optimizely Feature Experimentation
WebX and FeatureX work well in pair, they organically complement each other
Chose Optimizely Feature Experimentation
Simple interface and ability to create audiences and assign them to experiments.
Chose Optimizely Feature Experimentation
Optimizely offered both web experimentation (WSYWIG editor for nontechnical marketing folks) and Feature Experimentation. That made the decision easier to get max value across different stakeholder groups.
Chose Optimizely Feature Experimentation
Optimizely FX is the only tool I've used that specifically allows for testing in the back-end. Most front end tools are great for simple tests, but there comes a time when you need to go a level deeper and that's not possible with front-end tools.
Chose Optimizely Feature Experimentation
Mixpanel, Google Analytics, Hotjar and A/B Smartly
Chose Optimizely Feature Experimentation
I prefer Optimizely Feature Experimentation to web experimentation. I think it's more straightforward to set up and as an engineer, I like being able to have more control from the code side.
Chose Optimizely Feature Experimentation
we wanted a shift with the tool that helps us with managing our data
Chose Optimizely Feature Experimentation
We haven't evaluated other products. We have an in-house product that is missing a lot of features and is very behind from making the test process easier.

Instead of evolving our in-house product with limited resources, we decided to go with Optimizely Feature Experimentation …
Chose Optimizely Feature Experimentation
Overall, Optimizely Feature Experimentation is an industry leader in terms of experimentation across web and mobile. For apps I would say amplitude does slightly a better job as it is tailored to that niche.
Chose Optimizely Feature Experimentation
Optimizely Feature Experimentation is better for building more complex experiments than Optimizely Web. However, Optimizely Web is much easier to kickstart your experimentation program with as the learning curve is much lower, and dedicated developer resources are not always …
Chose Optimizely Feature Experimentation
Optimizely Feature Experimentation is less of a point solution than LaunchDarkly, so LD has a few extra features, but Optimizely offers a much greater solution for experimentation, personalization etc.
Chose Optimizely Feature Experimentation
Feature experimentation is much more robust and allows more granular control over the decisions you want to make. While Optimizely Feature Experimentation is nice and can be delivered via Optimizely Feature Experimentation's UI, its still not ideal because its brittle and can …
Chose Optimizely Feature Experimentation
Google Tag Manager was less flexible for the business and required the Google Analytics tool for analysis and metric tracking. Optimizely allows the building of use cases. Optimizely provides real-time data and metrics that are easier to use. GTM provides tracking …

Based on my experience with Optimizely Feature Experimentation, I can highlight several scenarios where it excels and a few where it may be less suitable. Well-suited scenarios: - Multi-Channel product launches - Complex A/B testing and feature flag management - Gradual rollout and risk mitigation Less suited scenarios: - Simple A/B tests (their Web Experimentation product is probably better for that) - Non-technical team usage -

If you are writing apis and you make a logic change for eg change format of a number from showing no decimal points to 2 decimal points, and screen of your older version of ui app does not have enough space on screen which makes the ux break, instead of releasing a new version of the api you can toggle off the feature for app versions lower than the one being targetted so that api keeps responding with zero decimal points for older app and with decimal points for the newer version of the app

Cons
  • Difficult integration if your data is not front end
  • Costly MAU model needs to be based on experiments not on site visits
  • It's not easy to understand how to build an Experiment
  • Onboarding team is more focused on punching through their slides and not focused on your needs or understanding.

Easy to navigate the UI. Once you know how to use it, it is very easy to run experiments. And when the experiment is setup, the SDK code variables are generated and available for developers to use immediately so they can quickly build the experiment code

In previous companies I've used Monetate which is a similar A/B testing kind of feature experimentation engine that is very similar from my memory, but again, back to the point of these new features of the analytics engine and Opal, it kind of cuts it above Monetate from my experience. Obviously Monetate may have improved since when I lost use it, but from what I can see, yeah.

Return on Investment
  • We have a huge, noteworthy ROI case study of how we did a SaaS onboarding revamp early this year. Our A/B test on a guided setup flow improved activation rates by 20 percent, which translated to over $1.2m in retained ARR.

The Unleash Client SDK polls the Unleash API at regular intervals and caches all feature toggles locally. The interval is configurable from the client-side.Screenshot of Overview of all feature toggles across all environmentsScreenshot of The enhanced list of users helps track account activity. It can display and sort by when an account is last logged in, to find inactive accounts.Screenshot of Custom context fields extend the Unleash Context with more data that is applicable to any situation. Each context field definition consists of a name and an optional description. Additionally, a set of legal values can be defined, or whether or not the context field can be used in custom stickiness calculations can be selected, for the gradual rollout strategy and for feature toggle variants.Screenshot of API tokens can be used to connect to the Unleash server API.
