The models' case: Best overall value: very low-startup isolate runtime, broad edge coverage, strong routing and caching, integrated WAF/rate limiting, and useful state primitives. The models' main caveat: Its proprietary runtime, 128 MB memory ceiling, and outbound-connection limits rule out heavyweight or highly connection-parallel gateways. The strongest alternative is Fastly Compute — Excellent latency consistency, per-request WebAssembly isolation, first-rate cache control, and serious Rust, Go, JavaScript, and C++ support make it.
