Portkey provides a unified API gateway sitting between applications and LLM providers. Route requests across 200+ models from OpenAI, Anthropic, Google, Azure, and others with a single API call.
Intelligent routing enables automatic failover when providers are down, load balancing across models, and cost-based routing that selects the cheapest capable model. Response caching reduces costs and latency for repeated queries.
Guardrails filter inputs and outputs for PII, toxicity, and custom rules. Request logging captures full request/response data for debugging. Prompt management and evaluation tools support iterative improvement.
The open-source gateway can be self-hosted for data sovereignty. Portkey Cloud adds managed observability, team collaboration, and enterprise features.
