Helicone

Helicone provides advanced caching mechanisms that store previous LLM responses, preventing redundant API calls and lowering expenses. Additionally, our detailed cost tracking dashboard allows you to identify expensive prompts and optimize your token usage across different models.

Absolutely. Helicone includes a robust prompt management system that lets you create, version, and test prompts. This allows your team to iterate on prompt engineering safely and deploy changes to production without needing to redeploy your entire codebase.

Helicone provides comprehensive request logging that captures the full input, output, and metadata for every call. You can easily filter and search through logs to identify why a specific request failed, analyze latency issues, or debug unexpected model behaviors in real-time.

Helicone is designed for seamless integration, requiring only a single line of code to get started. By simply changing your API base URL to Helicone's proxy, you can immediately begin logging and monitoring your LLM requests without rewriting your core application logic.

Yes, Helicone is an open-source platform, allowing you to host it yourself or use our managed cloud service. This flexibility is ideal for developers who want full control over their observability stack or need to test features in a local environment before moving to production.

Helicone supports a wide range of popular providers, including OpenAI, Anthropic, and many others via our flexible proxy architecture. If you use a provider that follows standard API patterns, you can likely integrate it with Helicone to gain full observability.

Yes, Helicone integrates smoothly with popular AI frameworks like LangChain and LlamaIndex. Since we operate at the network level as a proxy, you can simply pass the Helicone headers and base URL into these frameworks to start capturing detailed execution traces.

The Pro plan at $79/month is designed for growing teams needing advanced features like prompt management and longer data retention. The Team plan at $799/month is built for scaling companies that require higher rate limits, priority support, and more collaborative tools for larger organizations.

Yes, we offer a 'Hobby' plan specifically designed to help developers kickstart their AI projects at no cost. It includes essential logging and monitoring features, making it perfect for those in the early stages of development or building personal tools.

Security is a top priority for Helicone. We use industry-standard encryption for data at rest and in transit. For enterprise customers with strict compliance needs, we offer custom packages and the ability to self-host the platform to ensure data never leaves your infrastructure.

Helicone provides tools to help you manage sensitive data, including the ability to mask or redact specific information before it is stored. This ensures that your team can monitor performance and debug issues without compromising user privacy or violating data regulations.

Pro users receive standard email support to help with integration and troubleshooting. Team and Enterprise customers benefit from priority support channels, including dedicated Slack rooms and faster response times to ensure their production environments remain stable.
