Fireworks AI has saved my team around half of what we used to take because initially, we had to manually research all the models.
full stack developer intern at a tech services company with 1-10 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.

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.

Sentiment score
7.6
LaunchDarkly's scalability is mixed; some users find it scalable, while others suggest improvements and adopting Kubernetes for better performance.
It's clearly built for production workloads.
FullStack Developer at EnactOn Technologies
Fireworks AI is pretty scalable, and you do not have to worry about it with a few customers using it at a single point in time.
Product Manager at a tech vendor with 11-50 employees
Fireworks AI's scalability is good, but it might be slow sometimes, which could be an issue.
full stack developer intern at a tech services company with 1-10 employees
We do not face many problems regarding scalability.
Senior Software Engineer at a tech vendor with 1,001-5,000 employees
 

Stability Issues

6.6
LaunchDarkly is generally stable but faces inconsistent infrastructure, occasional downtime, and mixed backend performance perceptions.
We didn't face any major outages, just occasional slowdowns.
FullStack Developer at EnactOn Technologies
 

Room For Improvement

Fireworks AI requires better documentation, debugging, cost transparency, integrations, and user-friendly improvements to enhance flexibility and reduce expenses.
LaunchDarkly is costly and complex, with unclear documentation, needing better customer support, UI, control, and analytics enhancements.
Fireworks AI is based on tool calling, so I think it needs to add more other kinds of connections to enable faster data retention and optimization.
Ai스페셜리스트매니저 at a tech vendor with 501-1,000 employees
I think it has zero video generation capabilities, making it really hard for someone wanting to make a visual AI project.
full stack developer intern at a tech services company with 1-10 employees
A product sold as 'pay-as-you-go' should never produce a surprise $40,000 charge with no spending cap, no real-time threshold alert, and no notification.
Principal Software Engineer at a consultancy 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 have mixed views on LaunchDarkly pricing, citing high costs but some find it fair or customizable.
We received a sudden $40,000 charge via AWS Marketplace, which we obviously never used, and we filed a case for it.
Principal Software Engineer at a consultancy with 1-10 employees
 

Valuable Features

Fireworks AI enhances AI deployment with rapid speed, cost efficiency, seamless integration, and extensive customization, boosting performance and development.
LaunchDarkly provides efficient feature flags for faster deployment, gradual rollouts, and user-friendly API integration, enhancing operational efficiency.
It follows standard OpenAI-compatible endpoints, which meant we could swap out models or integrate new ones without rewriting our entire service layer.
FullStack Developer at EnactOn Technologies
After introducing Fireworks AI's high-speed inference engine, I found that communication speed between agents was about twice as fast as before.
Ai스페셜리스트매니저 at a tech vendor with 501-1,000 employees
Having access to multiple model tiers helps our team balance quality and cost by giving us leverage where we can make options and look at what best suits our company and what we could use, which is beneficial because when you have multiple choices, you can tailor your approach and get what you actually need, so our options are not limited.
Assistant Banking Officer at Zenith-bank
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.
Senior Software Engineer at a tech vendor with 1,001-5,000 employees

Automation has accelerated agent workflows and now needs broader connections for enterprise data
In the current function calling, if Fireworks AI could be added as part of our RAG system not only with the function calling we are using now but also with a variety of other connections, then an even better situation would be possible. Fireworks is based on tool calling, so it needs to add more different kinds of connections to enable faster data retention and optimization. Although multiple optimal optimization or measurement methodologies for using LLMs are being discussed, when using them inside enterprises, the main thing is actually measuring work handling capability or work processing speed. Based on that, and also through what might be called interviews with business-side staff, we measured the speed improvements in a somewhat indirect manner.

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.
