Top 5 AI Gateways to Use Claude Code with Non-Anthropic Models
Claude Code is a powerful terminal-based agentic coding tool that integrates seamlessly with Anthropic's models. However, production deployments often require flexibility to route requests across multiple providers, manage costs efficiently, and maintain failover redundancy. AI gateways solve this problem by creating an abstraction layer between Claude Code and any LLM provider.
This guide covers five enterprise-grade AI gateways that enable Claude Code to work with non-Anthropic models while maintaining performance, governance, and observability at scale.
1. Bifrost: High-Performance Multi-Provider Gateway
Platform Overview
Bifrost is an open-source AI gateway built by Maxim AI that unifies access to 20+ LLM providers through a single OpenAI-compatible API. Written in Go, Bifrost adds only 11 microseconds of latency overhead per request and handles 5,000 requests per second sustained throughput. This makes it the fastest gateway option for Claude Code, which makes dozens of API calls during agentic coding sessions.
Key Features
Bifrost provides enterprise-grade routing capabilities including automatic failover between providers, load balancing across multiple API keys, and semantic caching to reduce costs and latency. The gateway supports Model Context Protocol (MCP) for tool integration, allowing Claude Code to access external systems like databases and file systems. Budget management features include hierarchical cost controls with virtual keys and team-level budgets, enabling organizations to scale Claude Code safely across teams.
Advanced governance features include expression-based routing rules using CEL (Common Expression Language), comprehensive audit logging, and native observability through Prometheus metrics and distributed tracing. The platform integrates with HashiCorp Vault for secure API key management and supports SSO via Google and GitHub.
Best For
Bifrost is the optimal choice for teams running Claude Code at production scale. Organizations need fast, low-latency routing when developers are running rapid-fire agentic coding sessions. The platform excels in scenarios requiring cost optimization through intelligent routing, compliance-heavy environments needing detailed audit trails, and multi-team deployments where centralized governance is essential. See Bifrost documentation on unified interface and multi-provider support for setup details.
2. LiteLLM: Lightweight Multi-Model Router
Platform Overview
LiteLLM is a lightweight Python-based gateway that abstracts away differences between LLM provider APIs. It supports over 100 models across multiple providers and offers straightforward proxy configuration for Claude Code integration.
Key Features
LiteLLM provides basic routing capabilities, rate limiting, caching support, and fallback logic between providers. The platform includes cost tracking and logging functionality for monitoring API usage across different models.
Best For
LiteLLM suits teams seeking a simple, Python-native solution for multi-model support. However, Python-based gateways add approximately 8 milliseconds of latency overhead per request, which compounds during intensive agentic sessions where dozens of calls are made sequentially.
3. OpenRouter: Unified Model Marketplace
Platform Overview
OpenRouter aggregates access to hundreds of LLM models from various providers behind a single OpenAI-compatible endpoint. The service handles provider authentication and billing consolidation, simplifying multi-model deployments.
Key Features
OpenRouter offers model discovery and comparison tools, consolidated billing across providers, and native OpenAI API compatibility. The platform provides usage analytics and supports custom routing preferences based on model capabilities.
Best For
OpenRouter is ideal for teams exploring diverse model options without managing separate provider accounts. It works well for development and testing environments where consolidated billing and simplified API management are priorities over lowest-latency routing.
4. Cloudflare AI Gateway: Edge-Deployed Routing
Platform Overview
Cloudflare AI Gateway brings LLM request routing to the edge through Cloudflare's global network infrastructure. The service integrates with Cloudflare's broader security and performance platform for centralized request management.
Key Features
Cloudflare AI Gateway provides request caching, rate limiting, and DDoS protection integrated with Cloudflare's security services. The platform includes usage analytics and integrates with Cloudflare Workers for custom middleware logic.
Best For
Cloudflare AI Gateway benefits organizations already using Cloudflare services who need edge-level request management and security controls. It provides strong value for teams prioritizing security and global edge deployment over maximum throughput.
5. Ollama: Local Open Model Deployment
Platform Overview
Ollama enables local deployment of open-source models like Qwen and Llama with an Anthropic-compatible API. Models run entirely on local infrastructure without external API calls, providing data privacy and cost control.
Key Features
Ollama supports numerous open-source models, provides an Anthropic-compatible Messages API endpoint, and requires minimal configuration. The platform supports streaming responses and integrates directly with Claude Code through environment variable configuration.
Best For
Ollama is ideal for teams prioritizing data privacy, cost control through self-hosted infrastructure, or development environments where internet connectivity is limited. Organizations need models with sufficient context windows (minimum 64K tokens recommended) for complex agentic tasks.
Choosing Your Claude Code Gateway
Selecting the right gateway depends on your organization's specific priorities. Production teams requiring high performance, governance controls, and multi-team deployment should evaluate Bifrost. Teams already invested in Cloudflare infrastructure benefit from edge-level routing. Organizations exploring diverse models favor OpenRouter. Development teams with strong privacy requirements should consider Ollama.
Performance benchmarks matter significantly for Claude Code. During agentic coding sessions, a single developer might trigger hundreds of API calls. An 8-millisecond overhead per request (LiteLLM) versus 11 microseconds (Bifrost) compounds to meaningful differences in interactive responsiveness.
Enterprise deployments require governance features including audit logging, budget controls, and role-based access management. Bifrost provides these natively. Other gateways vary in native support for these capabilities.
Next Steps
Evaluate your primary use case: multi-team production scaling, development-only flexibility, privacy-first infrastructure, or edge security. Bifrost's open-source foundation and Go-based performance make it production-ready out of the box. For enterprise teams looking to standardize on Claude Code while maintaining cost control and governance, Bifrost integrates with Maxim AI's broader AI quality platform for evaluation, simulation, and observability.
