Best AI Gateways for Aider

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.

Kunavo serves as a centralized AI API gateway tailored for developers and teams, allowing them to manage a single account, utilize one API key, and maintain a prepaid credit balance to access a variety of models from different providers. This platform offers Chat Completions compatible with OpenAI and a dedicated endpoint for Anthropic Messages, all of which are detailed in its live catalog and API documentation. The service is capable of processing requests that encompass text, images, videos, and audio, depending on the chosen model and route. Developers can easily integrate supported SDKs, coding agents, workflow tools, and other clients by simply providing the base URL, key, and model identifier. A user-friendly dashboard tracks request usage and associated costs, and it allows API keys to have individual spending limits and IP allowlists to enhance security. Billing operates on a pay-as-you-go model against prepaid credit, with transparent rates that differ based on the model and modality, eliminating the need for a recurring subscription. Potential applications include the incorporation of model inference into various applications, streamlining coding workflows, automating processes, and enhancing customer support or data processing capabilities with AI. This flexibility makes Kunavo an appealing choice for teams looking to leverage multiple AI models efficiently.
