Zero-allocation web servers in roc

Web server framework with constant memory usage

Memory consumption in web servers is hard to predict and control. Our zero-allocation web server guarantees constant memory usage and per-request memory caps. These guarantees and capabilities make web infrastructure more reliable, because it is actually possible to calculate how much server capacity is required for a certain amount of traffic.

The vast majority of webservers are written in a language with automatic memory management. They cannot provide the guarantees that our webserver can, and often have other downsides like poor general performance and GC pauses.

The core of our webserver is written in rust, and while it works in a rust-only context, is meant to be used in combination with the roc programming language, a fast, friendly, functional language with automatic memory management, but without GC pauses. Users will be able to write web applications using roc, without having to consider how memory is allocated. At the same time, we manage the memory as efficiently as possible under the hood.
