Cloudflare Workers — Edge Compute for Agent API Proxies

Content

{
  "cons": [
    "128MB memory limit and 10ms CPU time limit (50ms on paid) constrain heavy compute tasks",
    "No Node.js built-in modules — many npm packages require polyfills or rewrites",
    "Durable Objects have regional affinity — global consistency patterns require careful design",
    "Wrangler CLI tooling has occasional breaking changes between major versions"
  ],
  "pros": [
    "Sub-5ms cold start globally — effectively no cold start penalty vs AWS Lambda",
    "Workers AI provides GPU inference at edge — useful for embedding generation near user",
    "KV, Durable Objects, and R2 provide consistent primitives for stateful edge agents",
    "Free tier includes 100k requests/day — adequate for prototyping and low-traffic APIs"
  ],
  "rating": 8,
  "verdict": "Ideal for lightweight API proxies and edge-side logic that needs global distribution. Not suitable for CPU-intensive tasks or packages with heavy Node.js dependencies. Combine with Hono for type-safe route handling.",
  "tool_name": "Cloudflare Workers",
  "use_cases": [
    "LLM API rate limit proxies",
    "Edge-side auth validation and token refresh",
    "Webhook ingestion and routing",
    "Low-latency agent API gateways"
  ],
  "version_tested": "Cloudflare Workers (2024 Q4)"
