Launched on June 27th, 2024
Kerno, as a lightweight runtime intelligence engine, effectively connects developers and AI code agents to help reduce technical debt. I find it useful for improving development efficiency, but the features feel somewhat basic for now. I look forward to more advanced monitoring and analytics in future updates.
From the moment I heard about the idea behind Kerno, I thought it was absolutely genius. My only concern was whether they could actually bring it to life—and somehow, they managed to do that flawlessly.

Hey PH! 👋
I'm Karim, the co-founder of Kerno, and I'm excited to share with you Kerno Core!
👀 The Problem
AI is now writing some code
CTOs are under pressure to accelerate AI adoption
But AI and developers are flying blind.
Production context is missing from the coding experience.
And without it, AI makes poor guesses. Developers lose time.
More technical debt, higher costs, and limited AI Agent utility.
Today's tools make it impossible for developers to obtain real-time production context.
Complex instrumentation
Heavy data pipelines
Noisy dashboards
Steep learning curves
Zero IDE native workflows
🎯 Our Mission
Make production context accessible to every developer and every AI assistant as they build.
We’re Kerno.

@karim_traiaia Seems like there is a typo in your description - 'Giev AI production context and reduce technical debt', should be 'Give'?

@ragsontherocks Hey Rags, thx. It's fixed now :D
Kerno Core sounds like a smart evolution for modern dev workflows — creating real-time feedback between live systems, developers, and AI agents keeps everything adaptive and in sync. Lightweight, but packed with impact. Excited to see it in action!
Kerno
Thank you @supa_l !!
Kerno
Thank you@supa_l would love to get your feedback once you give it a try :D

Very cool—runtime intelligence in this way feels like a glimpse of where software development is headed. Do you see Kerno Core eventually influencing how agents write or self-correct code in real time?
Kerno
Thanks @phily_hayes!
"Do you see Kerno Core eventually influencing how agents write or self-correct code in real time?"
Yeah, absolutely! Next week, we'll release the results of internal tests we've been running, in which Kerno core helps cursors self-correct much quicker and cheaper (with about 30% fewer tokens) than if it didn't have runtime context.
