Helicone

Helicone is a versatile platform designed to simplify the monitoring and optimization of applications powered by Large Language Models (LLMs). With its open-source foundation, Helicone allows developers to actively monitor their LLMs' performance, analyze usage trends, and implement data-driven improvements. This ensures efficient and reliable AI operations. In a world where AI-powered applications rely heavily on consistent performance, Helicone functions as a critical observability layer. It helps development teams understand how their models behave in production, providing insights that prevent outages, performance drops, and unexpected failures. Its open-source nature also makes it flexible and customizable for developers who want complete visibility and control over their LLM pipelines. Helicone equips developers with the tools to closely observe and enhance the performance of their AI models. Users can track request counts, response times, and error rates in real-time. This immediate feedback helps identify performance bottlenecks and areas for improvement. Developers can visualize trends in model performance, detect latency spikes, and analyze how changes in prompts or model configurations affect end-user experiences. Helicone’s detailed dashboards make it easy to correlate errors with specific model versions, user behaviors, or API integrations. Real-time alerts also ensure that teams can react quickly when performance deviates from expected levels. Beyond basic monitoring, Helicone provides detailed usage analytics that offer deeper insights into how models are performing across different environments. Developers can use these insights to optimize their applications, ensuring they deliver optimal performance and user satisfaction. These analytics go beyond raw numbers Helicone helps categorize requests, compare performance across LLM providers, and evaluate cost efficiency. Teams can use the platform to track token usage, understand prompt complexity, and identify which workflows use the most resources. This level of insight helps optimize pricing, reduce unnecessary calls, and improve latency across scaled AI applications. Offering a free plan for small-scale usage and paid options for more advanced features, Helicone serves both individual developers and businesses seeking scalable observability tools. The platform's design to grow alongside your needs guarantees that you always have access to the necessary tools, whether you’re just starting out or scaling up. Helicone is built with scalability in mind—developers can begin with basic monitoring and gradually unlock more sophisticated tools as their applications grow. It seamlessly integrates with major LLM providers such as OpenAI, Anthropic, and custom model deployments. For enterprises, Helicone provides compliance-ready solutions, robust access controls, and advanced security features needed for operating mission-critical AI systems.
