Portkey
Production AI gateway, load-balancing, and LLMOps control plane
About Portkey
Portkey is an enterprise-grade AI Gateway and LLMOps control plane designed to make production AI applications fast, reliable, and cost-efficient. By acting as a unified proxy between your applications and 250+ LLMs, Portkey handles automated provider fallbacks, load balancing, rate-limiting, and semantic caching with zero code changes. Engineering teams use Portkey to eliminate single-provider downtime risks (e.g. automatic failover from OpenAI to Anthropic during outages) while cutting inference latency and API costs by up to 40% through intelligent semantic caching.
Portkey provides comprehensive real-time observability, tracing every request, token cost, and latency percentile in a unified dashboard. The gateway supports fine-grained budget limits, user-level rate-limiting, and content moderation guardrails to protect production systems from abuse. With ultra-fast 10ms gateway overhead and SOC 2 Type II compliance, Portkey is engineered for high-throughput enterprise workloads.

Frequently Asked Questions
What is Portkey AI Gateway?
Portkey is a unified proxy and control plane for AI applications that manages LLM routing, automatic failovers, rate limiting, and cost-saving caching across 250+ models.
Does Portkey work with the standard OpenAI SDK?
Yes, Portkey is 100% drop-in compatible with the standard OpenAI SDK by simply updating the base URL and API key.
How does Portkey semantic caching save money?
Portkey caches semantically similar user queries and serves cached model responses instantly without making redundant, expensive calls to upstream LLM providers.

Enterprise AI evaluation, prompt playground, and continuous LLM monitoring
Braintrust is an enterprise-grade AI evaluation, prompt engineering, and LLM observability platform built to help software teams safely iterate and deploy generative AI features to production. It bridges the gap between ad-hoc prompt tweaking and rigorous software engineering CI/CD workflows. With Braintrust, teams run automated evaluation benchmarks on every prompt change, comparing output quality, hallucination rates, and latency across multiple LLM versions before committing changes to production codebases.
Langfuse
Open source LLM observability, tracing, and evaluation platform
Langfuse is an open-source LLM engineering and observability platform built for teams developing production-grade generative AI applications and autonomous multi-agent pipelines. It captures granular traces across token usage, prompt versions, latency bottlenecks, and retrieval accuracy, giving developers complete visibility into model behavior at runtime. By integrating seamlessly with major AI frameworks such as LangChain, LlamaIndex, LiteLLM, and the OpenAI SDK, Langfuse eliminates the guesswork from debugging complex agent execution trees. Developers can monitor production cost metrics, identify hallucinated responses, and run rigorous continuous evaluation suites on live traffic.
Anthropic Console
Enterprise-grade AI for developers
The developer gateway to Claude models, offering advanced controls like prompt caching and Artifacts rendering via API.
Agno
High-performance multimodal AI agent framework with native memory and speed
Agno (formerly Phidata) is a lightweight, ultra-fast Python framework engineered for building production-grade autonomous multi-agent systems with native memory, knowledge retrieval, and multimodal reasoning capabilities. It is designed to replace bloated agent frameworks with a pure, pythonic developer experience. Agno agents operate up to 10x faster than legacy orchestration libraries by eliminating unnecessary abstractions. With built-in support for vector databases (PgVector, Qdrant, Pinecone), structured output schemas, and agent-to-agent delegating protocols, developers can build complex autonomous assistants with under 20 lines of clean code.
Relevance AI
Build and deploy custom AI agents and workflows
Relevance AI is a platform designed to create AI workforces by combining LLM agents, tasks, and data pipelines. It provides an intuitive low-code workspace to build autonomous agents that execute multi-step operations.
LangChain
Build context-aware reasoning applications
The most popular framework for developing applications powered by large language models, including agents and RAG.
