Key features
Cloudflare Workers
Run serverless JS/Wasm at the edge with instant cold starts
Cloudflare Workers at $5/month is among the cheapest serverless entry points, and the free tier (100K requests/day) is genuinely generous for prototyping.
Watch out
CPU time is the real billing dimension, not requests. The included 30M CPU-ms sounds generous, but a single image-processing Worker using 50ms CPU per request exhausts it after just 600K requests/month, well under the 10M request allowance
Strengths
- +Global edge network
- +Great free tier
- +Low latency
Weaknesses
- -Limited runtime
- -Different programming model
