What is it?
Cloudflare Workers is a serverless compute platform that runs JavaScript, TypeScript, Rust, and Python at the edge — across 300+ data centers worldwide. Combined with D1 (SQLite database), KV (key-value store), R2 (object storage), and Queues, it forms a complete application platform without traditional server management.
Why does it matter?
Sub-millisecond cold starts eliminate the serverless “cold start tax” that plagues AWS Lambda and similar platforms. For latency-sensitive applications — APIs, auth flows, real-time data processing — Workers deliver consistent performance without provisioning or scaling decisions.
Trade-offs
Strengths:
- Near-zero cold start latency
- Global distribution by default (no region selection needed)
- Generous free tier (100K requests/day)
- D1, KV, R2, Queues create a cohesive ecosystem
- Wrangler CLI provides excellent local development experience
Limitations:
- 128MB memory limit constrains memory-intensive workloads
- D1 is still maturing (limited query complexity)
- Vendor lock-in for platform-specific APIs (KV, Durable Objects)
- CPU time limits (50ms on free, 30s on paid) restrict heavy computation
Our take
We run TechBlips entirely on Cloudflare’s stack — Pages for static content, Workers for API endpoints. For small-to-medium applications that need global performance without DevOps overhead, this is the strongest option available. The ecosystem maturity crossed our comfort threshold for production use in late 2025.
