Hey Product Hunt! 👋
I built Kōan because I kept hitting the same wall — AI agents failing in production with zero visibility into why.
The name comes from Zen Buddhism. A kōan is a riddle with no obvious answer — which is exactly what debugging a black-box AI agent feels like. Kōan makes the invisible visible.
A few things I'd love your feedback on:
1. Which provider integrations matter most to you?
2. What would make the event stream more useful for debugging?
3. Would team sharing / log export unlock this for your workflow?

Happy to answer any questions below! 🎋

Who hunted Kōan ?
Kōan was hunted by Ashish Sharda. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
