Deploy serverless code instantly across Cloudflare’s global network of 330+ data centers using V8 isolates for zero-cold-start performance.

Cloudflare Workers move logic to the edge, executing JavaScript, Rust, or Python within milliseconds of your users. By ditching traditional containers for V8 isolates, the platform eliminates cold starts and reduces overhead (memory limits typically sit at 128MB). You get built-in integration with KV storage, R2 object storage, and D1 SQL databases. It is the standard for building high-performance APIs, HTML rewriters, and full-stack applications that scale automatically without managing a single server or region.

### [Construindo LPs antes de perder tempo com MVP](https://curitiba.aitinkerers.org/talks/rsvp_JRMwzR5stSc)

Before writing a single line of backend code, you can validate whether anyone actually wants what you're building. This talk shows how to launch a pre-MVP in just a few hours using a landing page, PostHog, a Cloudflare Worker, and a small ad budget, and only build the real product if the data justifies it. The entire process was tested on a real project: Artesia.ink, a Duolingo-style app for learning art and history. During the demo, I showed how I used a custom Claude skill (startup-design) to refine the concept, validated the idea before building, created the first version with AI Studio, set up PostHog for visibility into user behavior, enabled email capture and notifications through a Cloudflare Worker connected to Resend, and launched Instagram and Meta ads to drive traffic and measure demand.
