GTmetrix is very well suited for small organizations or startups that do not have sufficient technical staff for site optimization. GTmetrix also comes with the free version, which allows users to use their service for free for up to three websites, which is a good option. However, this might not be the best option for a large organization that works in different technical domains and have a good number of technical staff.

If a new feature should be added but unsure of how it will actually work or how users will accept the new enhancement or change, this tool allows you test and measure initial results. This saves so much time and energy knowing the results before it is deployed and might have low user adoption or acceptance.

Pros
Gossamer Threads Inc.
  • Really complete report of performance issues.
  • Get reports from PageSpeed and YSlow at same time.
  • Gives a score from each separate tool, also displays loading time, page size and total requests very easily.

  • A/B or Multi Variant Testing as a methodology to gather insight from customer usage. Experimentation as a feature within LaunchDarkly offers information around the success of one variant over another and whether the experiment has reached statistical significance.
  • Being able to decouple deployment of code from the release of a feature is hugely valuable.
  • Development teams are empowered to manage features within their production applications for reliability or testing purposes.

Cons
Gossamer Threads Inc.
  • Deeper knowledge of page elements and their importance
  • Knowing which areas will have great impact beyond time of load speeds
  • Should drop any elements that do not reach a certain level of impact - to save distraction and get important issues dealt with

  • Limited number of users on cheaper plans that is limiting our ability to audit log who is making changes.
  • Some of our engineers are confused between flags and segments and have set up items incorrectly.
  • Better documented support for React with Typescript.

It's easy to use fast, data is easy to read and take aways are great too.

It's very easy to create new feature flags and set them properly. It is more difficult to get LaunchDarkly integrated within a distributed system so that flags can be used. Especially on stateless servers where gating features by user is not easy. Overall though, it is very easy to get started and I like how simple it is to use.

From what I have seen, LaunchDarkly integrates well with your code and also services you might have in your tech ecosystem. We use Jenkins for automation and we were able to use it to build pipelines to automate the control of LaunchDarkly toggles in our code.

I have never had the need to use GTmetrix support. Therefore, there is really no way for me to give a grade here. However, if you are on a paid plan my guess and it is a guess, is that their support is as good as the tool is. There are a lot more features in the paid plans, reporting. monitoring etc. I could see where support could come into play as these features are added to the account

Given we are doing the work to improve in Google to a large degree - the Google product is essential. But GTMetrix may use their info as well as other independent stuff to be a little better. I appreciate the way GTMetrix provides the info - cleaner and clearer and thus quicker to address.

LaunchDarkly stood out to us because it put control of the application within the hands of our engineers. We didn't want to allow business users to manipulate the production site via a third-party tool. Instead, our focus was on delivering faster as an engineering team.

  • Improved developer experience with some teams moving to Trunk-based Development.
  • Increased deployment frequency due to smaller code releases.
  • Validation of the technical and business value of work is achieved more quickly through smaller pieces of work and through experimenting with a small group of users before a feature gets to 100% of customers.
