Cloudflare AI Gateway vs Vercel AI Gateway
Updated March 10, 2026
Overview
Cloudflare AI Gateway is a proxy for AI API traffic that provides caching, rate limiting, analytics, and logging for LLM requests. Running on Cloudflare's global edge network, it reduces latency and costs by caching repeated requests. Free to use on all Cloudflare plans.
Vercel AI Gateway provides a unified API for accessing multiple LLM providers with built-in caching, rate limiting, and fallback routing. Integrated into the Vercel platform, it offers edge-optimized inference, usage analytics, and seamless integration with the Vercel AI SDK for production AI applications.

What each tool does well, and the limitations to keep in mind.
Pros
- Core features free with Cloudflare plans—no per-call gateway fees
- Tightly integrated with Cloudflare global network for low-latency routing
- One-line integration for major LLM providers
- Built-in caching, rate limiting, and fallbacks improve reliability
Cons
- Adds 10-50ms proxy latency to every request
- Lacks token-level tracing and prompt analysis
- Strict log retention caps require manual management at scale
- No enterprise governance features like RBAC or audit trails
Pros
- Zero markup on tokens with bring-your-own-key—transparent pricing
- USD 5 monthly free credit enables risk-free experimentation
- Excellent developer experience with minimal setup
- Automatic failover ensures reliability when providers fail
Cons
