Portkey is an AI gateway that acts as a unified interface between your application and 200+ LLM providers. It provides intelligent routing, automatic fallbacks, semantic caching, budget management, and guardrails — all through a single API that's compatible with the OpenAI SDK format. The gateway architecture means zero code changes to add reliability features: if OpenAI is down, Portkey automatically routes to Anthropic or other configured fallbacks. Semantic caching identifies similar queries and serves cached responses, reducing costs by 20-40%. The observability dashboard shows request logs, latency percentiles, token usage, and cost breakdowns across all providers. Guardrails enable content filtering, PII detection, and output validation before responses reach users. Portkey's virtual keys feature lets you manage API keys centrally without exposing them in application code. Free tier includes 10K requests/month with basic features.
