List of the Top 4 On-Prem AI Gateways in 2025

Effortlessly manage APIs across both cloud-based and on-premises environments: In addition to utilizing Azure, establish API gateways that work in tandem with APIs deployed across various cloud services and local infrastructures to optimize API traffic flow. It is crucial to uphold security and compliance standards while ensuring a unified management experience and full visibility over all APIs, both internal and external. Speed up your operations through integrated API management: Modern businesses are increasingly adopting API frameworks to drive their growth. Streamline your workflows in hybrid and multi-cloud environments by using a centralized platform to oversee all your APIs effectively. Protect your resources diligently: Exercise the option to selectively grant access to data and services for employees, partners, and clients by implementing measures for authentication, authorization, and usage limitations. This approach not only helps maintain tight control over access but also fosters collaboration and efficient interactions, thereby enhancing overall operational effectiveness. Ultimately, a robust API management strategy can be a key driver of innovation and efficiency within an organization.

LMOps is a comprehensive stack designed for launching production-ready applications that facilitate monitoring, model management, and additional features. Portkey serves as an alternative to OpenAI and similar API providers. With Portkey, you can efficiently oversee engines, parameters, and versions, enabling you to switch, upgrade, and test models with ease and assurance. You can also access aggregated metrics for your application and user activity, allowing for optimization of usage and control over API expenses. To safeguard your user data against malicious threats and accidental leaks, proactive alerts will notify you if any issues arise. You have the opportunity to evaluate your models under real-world scenarios and deploy those that exhibit the best performance. After spending more than two and a half years developing applications that utilize LLM APIs, we found that while creating a proof of concept was manageable in a weekend, the transition to production and ongoing management proved to be cumbersome. To address these challenges, we created Portkey to facilitate the effective deployment of large language model APIs in your applications. Whether or not you decide to give Portkey a try, we are committed to assisting you in your journey! Additionally, our team is here to provide support and share insights that can enhance your experience with LLM technologies.

Arch functions as an advanced gateway that protects, supervises, and customizes the performance of AI agents by fluidly connecting with your APIs. Utilizing Envoy Proxy, Arch guarantees secure data handling, smart traffic management, comprehensive monitoring, and smooth integration with backend systems, all while maintaining a separation from business logic. Its architecture operates externally, accommodating a range of programming languages, which facilitates quick deployments and seamless updates. Designed with cutting-edge sub-billion parameter Large Language Models (LLMs), Arch excels in carrying out critical prompt-related tasks, such as personalizing APIs through function invocation, applying prompt safeguards to reduce harmful content or circumventing attempts, and identifying shifts in intent to enhance both retrieval accuracy and response times. By expanding Envoy's cluster subsystem, Arch effectively oversees upstream connections to LLMs, promoting the development of powerful AI applications. In addition, it serves as a front-end gateway for AI applications, offering essential features like TLS termination, rate limiting, and prompt-based routing. These robust functionalities establish Arch as a vital resource for developers who aspire to improve the effectiveness and security of their AI-enhanced solutions, while also delivering a smooth user experience. Moreover, Arch's flexibility and adaptability ensure it can evolve alongside the rapidly changing landscape of AI technology.
