Running compute at the edge means you can transform and optimize content before it reaches your users — with sub-millisecond cold starts and no additional infrastructure. Every FastEdge worker runs on WebAssembly, providing sandboxed, predi

One of the most powerful features of edge computing is the ability to inspect and route traffic before it ever reaches your origin server. FastEdge gives you full programmatic control over request routing at every edge location worldwide.In

When your code runs across 100+ edge locations worldwide, understanding what each worker is doing becomes critical for debugging, optimization, and reliability. FastEdge provides logging and timing capabilities that give you visibility into

FastEdge provides distributed edge KV storage that lets you read and write data from any edge location worldwide. Unlike traditional centralized databases, edge KV stores data close to users — reads are served from the nearest PoP, making t

Security at the edge means threats are stopped before they reach your infrastructure. By implementing security logic in FastEdge workers, you can validate, filter, and block requests at the closest edge location to the user — providing the

The trick is to do all the hard work at build time. With Rust's build scripts, you can generate your HTML during compilation and embed it directly into the Wasm binary.The PatternCreate a build.rs file that renders the HTML and writes it to

FastEdge isn't just for responding to requests — you can also make outbound HTTP calls from your edge worker. This is useful for fetching data from upstream APIs, aggregating content, or acting as a proxy.The fastedge crate approachUsing th

FastEdge lets you run WebAssembly on the Gcore edge network — close to your users, with cold starts measured in microseconds. In this guide you'll build your first worker from scratch.PrerequisitesYou'll need Rust installed and the wasm32-w
