| Leaderboard | Cloudflare Rate Limiting | Envoy Rate Limit Service |
|---|---|---|
| Best API rate limiting services for distributed systems | #1 / 8 | #3 / 8 |
Why the models rank Cloudflare Rate Limiting — on best api rate limiting services for distributed systems
“Edge-deployed global distribution with proven massive scale (hundreds of millions of requests), sliding window accuracy, low latency enforcement before origin, integrated with WAF/DDoS protection, minimal ops for practitioners.”
Why the models rank Envoy Rate Limit Service — on best api rate limiting services for distributed systems
“The de facto standard for distributed rate limiting in service-mesh and gateway architectures — a gRPC service with Redis backing that Envoy, Istio, Contour, and Emissary all speak natively; battle-tested at Lyft/Google-scale traffic, open source, and it centralizes limit decisions across any number of proxy instances with descriptor-based rules that compose well (per-user, per-route, per-header). Assumes you already run Envoy or a mesh; that assumption drives its #1 rank because most distributed systems at scale in 2026 do.”
