Best alternatives to Lunary in 2026
Once an AI chatbot or agent is live, the hardest question to answer is usually 'why did it just say that?' — without proper logging, you're stuck trying to reproduce a bad response after the fact with no record of what actually happened. Lunary exists to close that gap: it traces every conversation, tool call, and decision your AI agent makes in production, so debugging becomes a matter of looking at a log instead of guessing. It ships SDKs for TypeScript, Python, and Go, and works with over 100 LLM providers through an OpenAI-compatible format, meaning it isn't locked to a single AI vendor. For companies in regulated industries, it includes PII masking and SOC 2 Type II / ISO 27001 compliance, which matters if your chatbot handles customer data. The free tier covers 10,000 events/month and 3 projects; the Team plan is $20/user/month for 50,000 events and unlimited projects with a year of retention; Enterprise adds self-hosting, SSO/SAML, and a 99.9% SLA.
