Lunary — LLM Chatbot Monitoring and Optimization for AI-Powered Businesses

Stop flying blind with your AI chatbots—Lunary gives you complete visibility into how your language models are performing, what's breaking, and exactly how to fix it.

What It Does for Your Business

Lunary is an open-source observability and management platform built specifically for teams running AI chatbots and agents. If you've deployed a customer-facing chatbot, internal AI assistant, or any system powered by large language models, Lunary shows you exactly what's happening under the hood. You get real-time monitoring of every conversation, detailed logs of AI responses, error tracking, and performance metrics—all in one dashboard. Instead of getting support tickets about "the chatbot gave a weird answer," you can actually see what went wrong, why it happened, and prevent it from happening again.

The platform handles prompt management, letting you version control your AI instructions, test different prompts against real conversations, and deploy updates without breaking production. For small businesses using AI to handle customer service, lead qualification, or internal workflows, this eliminates the guesswork. You're no longer hoping your $200/month AI tool is working—you know exactly what it's doing and its impact on your bottom line.

Key Features

• Real-Time Conversation Monitoring — Watch every chatbot interaction as it happens, see user inputs and AI responses, and catch problems before customers complain
• Prompt Version Control & Testing — Test new prompts against historical conversations to validate improvements before deploying to production
• Error Tracking & Alerts — Automatic detection of failed responses, hallucinations, and quality drops with configurable alerts sent to your team
• Analytics & Performance Metrics — Track response times, user satisfaction, completion rates, and cost per conversation to measure actual ROI
• Multi-LLM Support — Works with OpenAI, Anthropic, Google, and other language model providers—no vendor lock-in
• Open-Source & Self-Hostable — Deploy on your own servers or use the cloud version; full transparency into how your data is handled

Best For

E-commerce businesses running customer service chatbots, marketing agencies building AI tools for clients, SaaS companies with AI-powered features, professional services firms using AI for intake and intake, and any small business that's invested in AI automation but needs visibility into performance and reliability.

Pricing

Open-source and free to self-host, or cloud-hosted plans starting at around $99/month for small deployments, scaling based on conversation volume.

Business ROI

Small businesses typically save 5-10 hours per week on chatbot troubleshooting and debugging once they have visibility into what's actually happening. You'll identify which prompts are costing you money through failed interactions and fix them, easily recovering $200-500+ monthly in wasted API costs. More importantly, you prevent reputational damage from broken AI—catching a hallucinating chatbot before it reaches customers. Teams report 30-40% faster iteration cycles on AI improvements because testing is data-driven instead of guesswork. If your chatbot currently handles customer service, measuring actual performance lets you confidently increase its responsibilities and reduce human support costs by 15-25%.
