Best LLM Routers for Claude Code

OpenRouter is a unified AI inference platform that lets developers connect to a large catalog of models without integrating separately with every model provider. Through one API, users can access models from major AI companies including OpenAI, Google, Anthropic, Meta, Mistral, DeepSeek, Qwen, xAI, and numerous independent providers. The service supports multimodal workloads involving text, images, video, and audio. Developers can use a single account, credit balance, and API key across supported models instead of maintaining separate billing relationships and credentials. OpenRouter's routing infrastructure can prioritize providers based on factors such as price, latency, and reliability. Requests can also be redirected to alternate providers when a preferred endpoint becomes unavailable, helping applications maintain higher uptime. Organizations can configure data policies that restrict prompts to approved models and infrastructure providers. The platform provides benchmarks, model rankings, usage information, documentation, and developer tools for evaluating and deploying different models. OpenRouter is OpenAI API compatible, making it easier for teams to add broad model access to existing AI applications with limited integration changes.

Experiential serves as a gateway and inference platform powered by AI, designed for developers and organizations engaged in creating AI-driven products or internal solutions. It offers a consolidated API that directs requests to various hosted model providers, accounts supplied by customers, and self-hosted or custom models, including access to OpenAI and Anthropic APIs. Teams are equipped to oversee their API keys, budgets, and usage caps, while also being able to allocate costs to specific keys or agents, track requests, and set up provider routing along with fallback options. The service features both a complimentary plan and subscription-based monthly options, with an open-source version available for self-hosting. For enterprises, additional plans introduce organizational governance and data residency capabilities, and those on paid plans benefit from model optimization tools. Furthermore, enterprise clients have the unique opportunity to commission a model that is specifically trained on their traffic data. Developers can easily link up compatible applications and coding agents by simply adjusting their API endpoints and credentials, thereby enhancing integration flexibility. This comprehensive platform ultimately streamlines the process of implementing AI functionalities within various applications.

Openlayer is the enterprise AI governance platform for discovering, testing, monitoring, securing, and governing AI systems from development through production. Openlayer brings AI evaluation, observability, guardrails, compliance, gateway enforcement, and cost controls into one platform.

RelaySwitch serves as a centralized API gateway for developers, enabling them to access AI models from various providers via a unified endpoint and account. It offers an API that is compatible with OpenAI and accommodates the Anthropic Messages format for Claude models, which allows developers to easily integrate their preferred SDKs and tools by simply updating the base URL and API key. The platform features a diverse catalog that includes chat, image, video, speech, and 3D models, along with detailed model identifiers and token pricing. Billing is conducted using a prepaid USD balance, where separate rates for input and output are provided, and in some cases, utilizing cached input may be more economical. Users can replenish their balance through various accepted payment methods, including credit cards and digital assets, without the need for a monthly subscription. RelaySwitch is specifically designed for developers and teams focused on creating applications and agents utilizing hosted AI models, and it includes extensive API documentation, comprehensive model listings, and setup instructions to facilitate integration with supported SDKs and tools. Additionally, the platform aims to streamline the development process, making it easier for users to leverage advanced AI capabilities in their projects.

UnoRouter serves as a versatile gateway for accessing various OpenAI-compatible language models. With a single API key, users can unleash over 200 models from multiple providers including OpenAI, Anthropic, Google, and others, seamlessly integrating coding agents like Claude Code, Cline, Codex, and Kilo Code. By simply directing any OpenAI SDK to the designated base URL, users can effortlessly switch between models without needing to modify their existing code. Additionally, UnoRouter features an integrated chat and character client, which supports personas, lorebooks, and the import of SillyTavern cards, all accessible with the same API key. The platform operates on a usage-based pricing model that includes a free tier, ensuring users have access to live updates on model availability and pricing. This innovative approach simplifies the process of utilizing multiple AI models for various applications.

Concentrate AI serves as a centralized gateway for rapidly evolving teams, offering a single API that connects to all major LLM providers while consolidating routing, spending, logging, and controls. This platform empowers teams to securely leverage and manage artificial intelligence through a unified API, ensuring that each request is directed towards the most efficient, cost-effective, and high-performing model for specific tasks or workflows. With access to over 130 models, teams can evaluate speed, quality, and expense, seamlessly directing workloads to the most suitable options without having to integrate multiple provider APIs into their environments. Concentrate recognizes that different applications such as support bots, coding agents, internal tools, chat functions, and batch jobs have varying needs, allowing teams to choose model slugs, restrict authorized providers, prioritize based on real-time latency, and implement fallback strategies to redirect traffic when a provider encounters slowdowns, errors, or limitations. Additionally, it offers a comprehensive view of AI utilization for engineering, finance, security, and leadership teams, featuring detailed logs at the request level that include models used, provider information, duration, token usage, expenditure, error rates, alerts, and data export capabilities, thereby enhancing oversight and decision-making in AI deployment. This level of transparency and control allows organizations to optimize their AI strategies effectively.
