AI Gateway vs LiteLLM

Self-hosted vs managed: LiteLLM is free open-source software but requires self-hosting, DevOps, and monitoring ($500-2,000/month in hidden costs). AI Gateway is fully managed at $99/month with $5,000 usage budget and intelligent routing. Choose LiteLLM if you have a DevOps team and want full control. Choose AI Gateway if you want zero ops overhead.

Core Difference

LiteLLM = Open Source, Self-Hosted

LiteLLM is free, open-source software you run on your own infrastructure. You have full control, can customize everything, and pay $0 for the software itself. However, you pay for hosting, DevOps time, monitoring, and maintenance. Best for: teams with existing DevOps who want complete control.

AI Gateway = Fully Managed SaaS

AI Gateway is a managed service. No servers to maintain, no deployments, no monitoring setup. You get a URL and API key, and it just works. $99/month includes $5,000 usage budget, infrastructure, monitoring, and support. Best for: teams who want to ship fast without DevOps overhead.
