About Helicon

Built for AI Developers and Teams

Helicone is an open-source platform that gives developers complete visibility into the performance and behavior of large language model (LLM) applications. Designed for production-level observability, Helicone helps teams track API usage, debug prompts, evaluate outputs, and optimize user interactions with ease.

Trusted Infrastructure for LLM Workflows

Whether you're building with OpenAI, Anthropic, or other LLM providers, Helicone integrates seamlessly to bring clarity and control to your AI stack. With real-time monitoring and powerful debugging tools, it’s built to support developers from MVP to enterprise deployment.

Core Features of Helicone

LLM Observability Dashboard

Helicone’s intuitive dashboard lets developers monitor LLM usage, latency, errors, and cost across multiple providers and deployments. With detailed breakdowns and filters, you can pinpoint inefficiencies and make informed decisions.

Debug and Improve Prompt Engineering

Test and evaluate different prompt versions to see what performs best. Helicone’s built-in prompt playground and experiments module allow for fast iteration without redeploying your app.

Track API Requests and Sessions

From a single dashboard, visualize the entire lifecycle of your LLM interactions. Understand how users engage with your AI, detect anomalies, and improve performance in real time.

Experimentation and Evaluation

Run A/B tests or evaluate responses across datasets to refine model outputs. The evaluation framework helps you maintain high-quality, reliable user experiences.

Seamless Integrations

Helicone supports major LLM platforms and API providers, including:

• OpenAI
• Anthropic
• Azure OpenAI
• LiteLLM
• Together AI
• Anyscale
• OpenRouter

Integrate with just a few lines of code and start capturing valuable insights from day one.
