Cloudflare Workers is rated higher (4.3 vs 3.9). Google Cloud Functions is GCP's serverless compute. HTTP-triggered or event-driven. 2M free invocations/month. Node.js, Python, Go, Java, Ruby, PHP, and .NET supported. Deep integration with Firebase. Run JavaScript, Python, and Rust functions at the edge with sub-millisecond latency. Ideal for APIs, middleware, and full-stack applications needing global distribution.

Google Cloud Functions
Pros
- + 2 million free invocations per month, permanently, per billing account
- + Published 99.95% uptime SLA with 10/25/50% financial credits
- + 2nd gen on Cloud Run infrastructure: concurrency, Eventarc triggers, traffic splitting, GPU access
- + First-class Firebase, Pub/Sub, Cloud Storage, and Secret Manager integration
Cons
- - GCP lock-in: events, IAM, and deployment are Google Cloud objects
- - Gen 1 / gen 2 split means two pricing models and two capability levels in one product
- - Costs scale with abuse and bugs — every failed invocation is billed, no per-function spend cap
- - Container image storage (Artifact Registry) bills separately even within the free tier
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
