Best Cloudflare Workers alternatives in 2026

Cloudflare Workers runs JavaScript, TypeScript, and WebAssembly at the edge in 200+ cities worldwide. Deploy serverless functions with sub-millisecond cold starts. KV and Durable Objects provide global data storage.

Here are the real cost and limitation gotchas that push teams to look elsewhere:

• •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
• •KV storage charges separately: $0.50/M reads, $5.00/M writes, $0.50/GB-month storage. A medium-traffic cache with 5M reads and 500K writes/month adds $4.00/month on top of the base $5
• •Durable Objects pricing is complex: $0.15/M requests plus $12.50/M GB-seconds of duration. A real-time collaborative app with 1M DO requests and persistent WebSocket connections can easily cost $20-50/month in DO charges alone
• •D1 database bills per row read/written after generous free tiers (25B reads, 50M writes). Heavy read workloads stay cheap, but write-heavy apps at $1.00/M rows written add up: 10M writes/month = $10/month extra
