Ship LLMs without the fragility

Portkey is the reliability layer between your app and the model providers. One integration, then route, retry, cache, and monitor every call without touching your code again.

Who it's for: Engineering and platform teams putting LLMs into production who need uptime, cost control, and audit trails.

Key features

Unified API

Call 200+ models through one OpenAI-compatible endpoint.

Fallbacks & load balancing

Auto-route around outages and split traffic across providers.

Observability

Trace every request, token, and latency spike in a dashboard.

Guardrails & caching

Add safety checks and semantic caching to cut cost and risk.

The honest take

✓ What works

  • One integration for every provider
  • Saves you when a provider goes down
  • Clear cost and latency analytics
  • Generous free tier

✗ What doesn't

  • Another dependency in your stack
  • Advanced features need paid plans
  • Learning curve on config
  • Some providers better supported than others

Verdict

Portkey is the boring, essential infrastructure every production LLM app should have. If you're calling a model provider directly in prod, you're one outage away from wishing you'd used it.
