TraceAgently is an observability API for AI agents. Drop a few lines into any agent and get a real-time dashboard showing every thought, tool call, tool result, and error in the exact order they happened.
AI agents fail silently. Your logs show nothing useful. You have no idea if your agent called the wrong tool, looped, or hit a token limit.
Raw OpenAI, Claude, Gemini, LangChain, CrewAI, or any custom loop. No framework lock-in.
Free tier: 5,000 events/month, no credit card.
