Testimonials


HEAR IT FROM THE TRAILBLAZERS.

Our customers ship better LLM products. Hear it from them.

Thomas Steinacher
CTO & Co-Founder of Close.com



Lunary has become essential to supporting Close's GenAI work. The Lunary team
consistently delivers improvements and new features quickly, and their
Kubernetes setup is of high quality.
Ioannis
Product Manager at DHL



Lunary has proven to be an invaluable tool and great addition to our technology
stack. Its contribution has significantly enhanced the capabilities of our GenAI
solutions, bringing real value by optimizing our processes and offering advanced
insights.
Bart van der Meeren
CTO & Co-Founder of Growf



Very happy with Lunary AI as it requires no oversight from us and can always
trust that it works reliably. We were setup in minutes and directly got to
monitoring and improving our prompts. Integration into our stack was painless,
providing from day-1 features like logging and tracing. Definitely can say we
significantly improved the performance and efficiency of our LLM agents at
Growf. GDPR compliance is a must as an European company, so the cloud version
ended up being perfect for us. Plus really like the platform being open-source,
gives us transparency that we highly value. Highly recommend it to any
organization working with LLMs.

Morgan Pelissier
CEO & Co-Founder of Sparkmate Ltd



We've initially started using Lunary for the analytics & prompt features, but
have now fully integrated it across our AI stack. Setting up hallucination
guardrails has been a game-changer for the accuracy of our results.

No-nonsense OSS LLM Monitoring tool - one of the best out there!
Esben Christian Volsgaard
Founder at Tutur.io



Lunary has helped me reduce costs for the LLMs I use, and keep track of the
users with the highest usage. Another thing I love is the "Chats" functionality:
I can see how users directly interact with my product, along with the latency.
Prabir Vora
CEO & Co-founder of Alayna



We've been using Lunary in our production app for quite some time now and the
experience has been great. The team has been quick in assisting for any issues
as well as very considerate in taking inputs for their roadmap. Keep up the
great work!
Edvaldo Gjonikaj
CTO & co-founder @ TextYess



This is a must have if you're developing LLM products, it's so easy to integrate
and gives a lot of value to the whole team.
Pankaj Garkoti
SWE at Mavex



Great interface. Easy integration. No more combing the server logs to see what
went wrong.
Kaancan
Building stuff with AI



Just came across this repo. This is awesome. I looked into some other options
but always wanted something open-source. I even started my own project because
of that, but will discontinue that because Lunary looks great.
Sivan Helfer
SRE at SPIRITT



After searching a while for a good LLMops solution for our startup, I was lucky
to stumble upon Lunary. I can declare with confidence that this is going to be a
long relationship. Super easy to implement, super comfortable to interact, and
above all - a delight to interact with the team who keeps improving Lunary.
Thanks a lot guys, looking forward to keep working with you and Lunary!
