About Yaws
Yaws (Yet Another Web Server) is a high-performance, open-source web server written in Erlang, designed to handle large numbers of concurrent connections with low memory overhead. Its architecture leverages Erlang's concurrency model to serve thousands of simultaneous requests efficiently.
Yaws is particularly well-suited for dynamic web applications and REST APIs that require high concurrency, and it supports WebSockets, SSL/TLS, and server-side Erlang scripting. While not as widely deployed as Apache or Nginx, Yaws has a dedicated following among Erlang developers and is used in telecommunications, financial, and real-time web applications where Erlang's fault-tolerance characteristics are valued.
