Know exactly what your AI is doing and what it costs. Carbon captures every LLM and tool call in 2 lines of code and turns it into a queryable ledger — cost over time, spend by model, heaviest users, tool failures, where agents stall. Every provider, 1,000 events free.
Hi Product Hunt — Pranjal here.
We started building with LLMs like everyone else: wire up a few providers, ship fast, watch it work. Then the bill came — one number, no story behind it. We couldn't tell which feature, which agent, or which user was driving it, and our logs were a million rows nobody wanted to read. The questions that actually decide the roadmap went unanswered:
• Why did our AI bill double this month?
• Which agent burned $300 last Tuesday?
• Which model is actually cheapest for this task?
We were optimizing our most expensive system blindly. So we built Carbon.
How it works:
• Wrap your existing client in 2 lines of code — every call is captured automatically
• One ledger across every provider: OpenAI, Anthropic, Google, Vercel, Mistral, OpenRouter, DeepSeek and more
• Drill into clusters — cost, models, your heaviest users, and where agents stall
• Built for humans and the agents in your stack: we track tool calls, not just chat
It's free forever for 1,000 events/month, no credit card.
I'll be here all day. Tell me the one question about your AI you can never answer today, and I'll show you the Carbon view that answers it.
