Vermell

A minimal, zero-bloat web framework designed for modern C++ environments. Fast, structural, and strictly typed.

Vermell is a web framework for modern C++ environments : one header to include, one static library to link, and nothing else. No runtime, no garbage collector, no framework-specific DSL, no vendored dependencies — what you write is C++, and what runs is C++.

Under the hood it is an event-driven engine: a non-blocking epoll loop reads requests and hands work to a pool of worker threads. That split is what makes Vermell fast under load and resilient against slow clients.

Zero dependencies — only base Linux APIs (sockets, epoll, pthreads, fork/exec).

One command to build — g++ -std=c++20 server.cpp -o exe -lvermell .

Any Linux with g++ — x86_64, ARM (aarch64, armv7), Android via Termux, WSL, Raspberry Pi, containers.

Hardened by default — timeouts, request caps, connection limits and a render jail are on out of the box.

In-tree JSON DOM — strict RFC 8259 parser and serializer, typed parameters, raw bodies, multipart uploads.

A Vermell server is a Router : register a handler for a route, choose a port, and call listen() .

For larger projects use CMake, but a server is always one command away.

The router exposes one registration method per HTTP verb. Static routes dispatch in O(1) through a transparent-hash route map.
