ROI

Sentiment score
7.0
Gremlin's platform improved ROI by reducing costs and downtime, streamlining error identification, and enhancing availability with efficient Chaos Engineering.
Sentiment score
7.0
LaunchDarkly improved deployment efficiency for some teams, though others faced challenges with infrastructure costs and Terraform configuration.
We are seeing a return on investment from using Gremlin Reliability Management Platform because we are getting less production issues by thirty percent, as I mentioned earlier, making it a great investment.
DEVOPS specialist at a media company with 10,001+ employees
We do not need to look at all the day's metrics on Grafana dashboards; we run our chaos experiments in a production environment to see how reliable our product or service is.
DevOps & Mlops Engineer at a printing company with 1-10 employees
If we needed ten people to do tests once upon a time, now, using Gremlin Reliability Management Platform, we can do it with a fifty percent reduction in employees.
Senior Software Engineer at a sports company with 10,001+ employees
We were eventually able to get it to a point where a very small team could administer access to LaunchDarkly for thousands of employees.
Staff Software Engineer at a wholesaler/distributor with 10,001+ employees
I cannot speak on money saved, but time saved is evident because we can ship products faster with more confidence, although I do not have metrics to quantify it.

Room For Improvement

Gremlin could improve through AI-driven analysis, better user onboarding, expanded service integrations, enhanced UI, and additional learning resources.
LaunchDarkly struggles with high costs, complex management, unclear documentation, unreliable support, and a cumbersome, non-intuitive user interface.
I think it would be useful to have some integration with Splunk or other log collectors, or maybe in the future, the ability to link Dynatrace or any other observability platform.
Dev Ops To Development (IT) at a non-tech company with self employed
If we can integrate it with natural language, could we talk to Gremlin Reliability Management Platform and have it configure some of the basic settings so that non-technical persons can also work on Gremlin Reliability Management Platform-like tools?
DEVOPS specialist at a media company with 10,001+ employees
The user interface is great, the integration is smooth, and Gremlin Reliability Management Platform has a fantastic support team that helps us a lot in many cases.
DevOps & Mlops Engineer at a printing company with 1-10 employees
Making one feature toggle or one set of feature toggles dependent on another one would allow us to turn them all on or turn them all off at one time.
Staff Software Engineer at a wholesaler/distributor with 10,001+ employees
I did not particularly like the rule area; there are many things to add into the rule to enable it, and I think we could make it easier or more customizable at the organizational level.
Senior Software Engineer at a tech vendor with 1,001-5,000 employees
 

Setup Cost

Enterprise users value Gremlin's platform for reliability and risk management, justifying costs despite visibility challenges in dashboards.
Enterprise users have mixed views on LaunchDarkly pricing, seeing it as expensive or fair, with varying licensing costs.
It is not so cheap, but it has very powerful features.
Dev Ops To Development (IT) at a non-tech company with self employed
From a pricing standpoint of view regarding Gremlin Reliability Management Platform, I would say it is a bit expensive, but that expense is worth it given the kind of benefits it offers.
VP Global at a tech vendor with 10,001+ employees
My role does not incur costs for us since we have an NFR for Gremlin Reliability Management Platform that we can use in our case.
DevOps & Mlops Engineer at a printing company with 1-10 employees
 

Valuable Features

Gremlin enhances efficiency with test suites, fault injection, risk detection, and reliability insights, boosting uptime and customer satisfaction.
LaunchDarkly provides feature flagging and experimentation tools with intuitive UI, supporting efficient deployment, targeting, API integration, and performance improvements.
There are really two pathways along: fewer incidents because with Gremlin Reliability Management Platform, we can make every part of the infrastructure more solid, and less downtime because we can test more architectures and then things like how to put in high availability clusters.
Dev Ops To Development (IT) at a non-tech company with self employed
We fix failures even before they occur, which is basically proactive risk detection and risk mitigation.
VP Global at a tech vendor with 10,001+ employees
Gremlin Reliability Management Platform has positively impacted our organization by making outages less frequent and improving recovery time significantly, resulting in fewer complaints on the customer success side and overall optimization of our DevOps process.
Documentation Engineer at a tech vendor with 1,001-5,000 employees
The main functionality of LaunchDarkly is providing feature toggle functionality.
Staff Software Engineer at a wholesaler/distributor with 10,001+ employees
LaunchDarkly stands out due to its ease of use, deployability across environments, and the ability to easily toggle features, which are all beneficial qualities.

VP Global at a tech vendor with 10,001+ employees
Proactive failure testing has increased confidence and reliability across complex microservices
There are certain areas where I think Gremlin Reliability Management Platform can improve. I would certainly add features related to AI and GenAI for recommendations. While dependency identification works well seamlessly, deeper dependency intelligence is lacking. When you have deeper dependencies, reliability management can struggle with identifying those deeper dependency intelligences. Having the intelligence to deeply analyze dependencies will be very helpful. Regarding reliability scores, while those scores are good, having more actionable reliability scores is something I would recommend adding to the existing system. Initially, when I started with Gremlin Reliability Management Platform certification programs, I completed two certifications with Gremlin—one professional and another practitioner. While that certification has helped me, an easier onboarding and learning curve for bringing people into this program can be adjusted. That is one current gap I see. If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform. If Gremlin Reliability Management Platform could help realize that and bring in visibility regarding the cost versus the benefit, that is the reason I provide a score less than ten. From a standpoint of simulating complex real-world failures, I believe there is still a gap concerning gap identification. Currently, Gremlin Reliability Management Platform mainly focuses on infrastructure-level failures and does not really simulate business logic failures, data corruption scenarios, or potential failures across regions. One of the key elements needing improvement with Gremlin Reliability Management Platform is the limited team workflow integration I see in my organization. Collaboration and limited team workflow integration are areas I would highlight as needing improvement.

Has increased developer confidence by enabling safe production releases using targeted feature toggles
I wish we were using more targeting in our feature toggles and I wish we were using more feature toggles as well as feature toggle dependencies. Making one feature toggle or one set of feature toggles dependent on another one would allow us to turn them all on or turn them all off at one time. For improvements in LaunchDarkly, managing team members and access to those team members was challenging. We could add team members through Terraform and do it programmatically, and then modify it through the user interface. However, once we started modifying things through the interface, we weren't able to go back to using any configuration programmatically for the team members. It made it challenging to orchestrate team member management. The other aspect I wasn't particularly fond of was when they started adding AI to the interface and deployment interface. It reminded me of old school wizards when installing software and simplified the interface too much, removing some of the engineering control I preferred.
