Just add your API key and run.

Just shipped - v3 update
We've been heads-down building and just pushed a bunch of features based on early feedback:
What's new:
Sessions now persist — your API keys and agents survive browser refreshes. No more re-entering everything.
Search your agent logs — filter the live event stream by keyword or event type in real time.
Test your API keys — one click to verify a provider connection before running agents. Instant ✓ or ✗.
Copy any log entry — hover any event and copy the message instantly.
Keyboard shortcut — press R to run all agents, Esc to close modals.
Agent run counter — see how many times each agent has fired this session.
Import / Export agents — back up your agent configs as JSON or share them with your team.
Light & dark mode — toggle between themes from the header. Your preference is saved automatically.
Still free, still BYOK (bring your own keys), still works with Anthropic, OpenAI, Gemini, and any OpenAI-compatible API.
More coming soon — would love to hear what you want next. Drop a comment
Kōan
Update — Day 3 🎋
Shipped a few improvements based on your feedback:
→ Clearer positioning: Kōan is agent observability — not just a log viewer or debugger.
→ JSON + CSV export: download full agent sessions for offline debugging, sharing, or analysis.
→ Session sharing: generate a URL and share exactly what your agent did — reasoning steps, tool calls, and decisions included.
→ Clearer empty state: new users now know exactly what to do when they land.
Kōan works with OpenAI, Anthropic, Gemini, DeepSeek, Mistral, Ollama, and custom endpoints.
Still free. Still BYOK. Still no signup.
