Fastly Compute@Edge
0 reviews
4.3/5
Cloudflare Workers
0 reviews
Cloudflare Workers is rated higher (4.3 vs 3.8). Fastly Compute@Edge runs WebAssembly serverless functions at Fastly's edge PoPs globally. Ultra-low latency, near-instant startup, and support for Rust, JavaScript, Go, and other WASM-compiled languages. Run JavaScript, Python, and Rust functions at the edge with sub-millisecond latency. Ideal for APIs, middleware, and full-stack applications needing global distribution.

Fastly Compute@Edge
Pros
- + Per-request WebAssembly sandboxes with very fast startup — effectively no cold starts
- + Generous free allowances: 10 million requests and 100 million vCPU-milliseconds free every month
- + Billing by requests and vCPU only (duration meter removed for new purchases) rewards efficient code
- + Runs globally on Fastly's 100+ PoP network with HTTP/3, IPv6 and DDoS mitigation included
- + Official SDKs for Rust, JavaScript, Go and C++, plus KV Store, Secret Store, Object Store and Fanout
Cons
- - WASM compilation and capability-based sandboxing add real tooling friction versus mainstream serverless
- - Free-trial state on first deploy, account-type-dependent limits, and two legacy pricing regimes complicate planning
- - Edge state stores use Fastly-specific APIs — no S3-compatible or Redis-compatible interface
- - Outside the official SDK languages, you are a pioneer; long-running workloads do not fit
- - Production use pushes toward a sales conversation rather than pure self-serve
Cloudflare Workers
Pros
- + No cold starts: V8 isolates start in microseconds at 330+ locations
- + CPU-time billing with a genuinely usable free tier (100k requests/day)
- + No egress or bandwidth charges on any plan
- + Storage stack (KV, D1, Durable Objects, R2) binds declaratively and stays in-network
- + Strong docs: pricing and limits pages are explicit and example-driven
Cons
- - CPU time caps exclude compute-heavy and long-running workloads
- - Real vendor lock-in through Durable Objects, bindings and deployment model
- - KV writes ($5.00/M) and Durable Objects duration billing surprise stateful designs
- - Conceptual shift for teams used to container-based serverless
- - No uptime SLA below the Business plan
