When designing modern micro-SaaS web utilities (calculators, formatters, text cleaners), developers often default to Serverless Edge Functions or Server-Side Rendering (SSR).
However, for single-task utility sites, this approach often introduces unnecessary architecture overhead: cold-start latency, cloud costs, and potential data privacy concerns.
Here is why adopting a Pure Client-Side Static Export (output: 'export') model is often a superior architectural decision.
1. Zero Cloud Overhead & Unlimited Scalability
Serverless functions offer free tiers, but traffic spikes or malicious bot attacks can quickly trigger unexpected usage billing.
