The platform is available as both open-source for self-hosting and as a managed cloud service with generous free tiers. Helicone helps teams understand and optimize their AI applications through comprehensive observability.

Portkey is an AI gateway and control panel trusted by thousands of development teams worldwide, providing comprehensive infrastructure for production AI applications. The platform processes over 10 billion LLM requests monthly with 99.9999% uptime and sub-40ms latency. Portkey's suite includes AI Gateway, Guardrails, Observability, and Prompt Management, routing requests to 1600+ models across major providers through a unified interface. Users praise easy integration, intuitive dashboards, dedicated support, and analytics providing detailed insights into traces, errors, caching, and cost visibility. However, real-world deployments often experience 20-40ms latency overhead (higher than claimed), with Kong benchmarks showing competitors 228% faster. Pricing typically ranges USD 2,000-10,000+ monthly depending on volume and deployment model. While powerful for enterprises, the platform can be overwhelming for new users and may require separate tools for comprehensive MLOps capabilities.
