Editorial Verdict
Best for
Platform teams managing AI access across an organizationDevelopers building LLM-powered apps needing reliability and observabilityEnterprise teams requiring governance, security, and complianceTeams running AI agents in production needing guardrails and monitoringOrganizations with high-volume LLM workloads optimizing cost and performance
Not ideal for
Hobbyists who only need a single model with no monitoringTeams wanting a fully self-hosted open-source solution without enterprise featuresUsers seeking a no-code AI agent builder (Portkey is developer-focused)Those who need on-device or offline inferenceTeams needing very long log retention on the free plan (only 3 days)
Portkey's AI Gateway is a comprehensive, battle-tested solution for teams scaling LLM usage with control. Its free tier is generous, and enterprise features are robust. Best for developers and platform teams, not end-users.

About Gateway
FreemiumIntermediateAPI availableAPI · CLI
Portkey's AI Gateway is a unified API layer that lets you connect to over 1600 LLMs from 250+ providers, with built-in guardrails, caching, routing, and observability. It is designed for teams that need to manage, secure, and optimize AI interactions at scale, from prototyping to production. The gateway acts as a proxy between your application and the LLM providers, handling key management, fallbacks, load balancing, retries, and more. What sets it apart is its combination of enterprise-grade features (SSO, SOC 2, HIPAA) with a developer-friendly open-source core and a generous free tier. It also includes an MCP Gateway for agent governance and a Prompt Studio for prompt management.
Behind the Verdict
We'd reach for Portkey's AI Gateway when we need a single reliable proxy to manage dozens of LLM integrations without rewriting code. Its free tier (10k logs/month) is perfect for prototyping, and the $49/month Production plan unlocks semantic caching and LLM guardrails. Where it bites: observability logs retention is only 3 days on free, and the self-hosted open-source version lacks the full monitoring stack. Compared to competitors like MLflow Gateway or Kong Konnect, Portkey offers tighter integration with LLM-specific features (virtual keys, prompt studio, canary testing). That said, if you're already deep in AWS Bedrock or Azure OpenAI, the native console might suffice. Portkey's MCP Gateway for agent governance is a forward-looking addition, but the docs on that are still maturing. For large enterprises, the custom plan includes private cloud and HIPAA compliance, but expect to negotiate. In practice, we've seen teams adopt Portkey to cut provider costs by 30% via caching alone. The CLI setup (npx @portkey-ai/gateway) is slick, but the dashboard's log search can be slow at high volumes.

Use Cases
- Route requests to the optimal LLM based on cost, latency, or custom rules.
- Automatically failover to a backup provider when primary is unavailable.
- Cache semantically similar prompts to reduce API costs and speed up responses.
- Monitor and analyze all LLM calls with detailed logs, traces, and cost breakdowns.
- Enforce guardrails to filter harmful content or validate outputs before returning to users.
- Manage API keys centrally with virtual keys and usage controls.
Limitations
- The free tier limits logs to 10k per month and 3-day retention; exceeding costs extra.
- Some advanced features like custom guardrails, SSO, and private cloud are only on the Enterprise plan.
- There is no dedicated desktop or mobile app—gateway is API/CLI only.
